On the 2010-2017 Chevrolet Equinox 2.4L Ecotec, the 2.4L Ecotec engine uses low-tension piston rings that fail to maintain proper tension to keep oil in the crankcase. Vehicles consume 1 quart of oil per 800-1,000 miles. This defect can cause premature engine wear, engine failure, and potential fire risk if oil levels drop critically low. GM acknowledged this defect through TSBs and class action settlements.
Piston ring replacement (may not be permanent fix). Complete piston assembly replacement with updated GM parts. Engine replacement with revised long block. Check eligibility for Special Coverage Adjustment 16118.
Owner tips & cautions
TipGM has a formal oil consumption test procedure - ask dealer to perform it. If consumption exceeds 1qt/2,000 miles, GM may authorize piston ring replacement under warranty.
TipUse Dexos1 Gen 2 certified 5W-30 full synthetic oil. Some owners report reduced consumption with slightly heavier oil but this may void warranty.
WarningCheck oil level every 1,000 miles on 2.4L Equinox - running low damages the timing chain and bearings

On the 2010-2013 Chevrolet Equinox 2.4L Ecotec, the 2.4L Ecotec engine is prone to premature timing chain failure due to improperly hardened chains and faulty tensioners. A defective batch of timing chains that were not hardened properly causes the chains to stretch prematurely. When the timing chain fails or jumps teeth on the sprockets, it can cause catastrophic valve damage and complete engine failure.
Replace timing chain, tensioners, and guides. Inspect and replace damaged valves if timing jumped. Complete engine replacement if severe damage occurred. Check for GM Special Coverage letter for warranty extension.

On the 2010-2017 Chevrolet Equinox 2.4L LAF/LEA Ecotec I4, the 2.4L Ecotec in 2010-2017 Equinox is prone to premature timing-chain and balance-chain stretch, driven primarily by a collapsing chain tensioner and made worse by the engine's known oil-consumption problem (low oil reduces hydraulic pressure to the tensioner). Symptoms are a rattle at cold startup, a check-engine light, and rough running or loss of power. Because the engine is an interference design, a chain that skips timing far enough lets the valves contact the pistons, turning a maintenance item into an engine-destroying failure. GM issued Special Coverage Adjustment 12313D covering premature timing/balance chain wear on certain 2010-2011 2.4L engines.
Check engine light with cam-crank correlation codes
Rough idle, hesitation, reduced power
Engine running rough or stalling
How to Fix
Diagnose with cam/crank correlation codes and inspect chain stretch. Replace the full timing chain kit (chains, guides, tensioners) and the balance chain; correct any underlying oil consumption first or the new chain will wear early. Address promptly at first rattle — driving on a stretched chain risks valve-to-piston contact and a totaled engine.

On the 2010-2017 Chevrolet Equinox 2.4L LAF/LEA Ecotec I4, the 2.4L Ecotec (LAF/LEA) four-cylinder used in 2010-2017 Equinox (and its GMC Terrain twin) consumes oil at an abnormal rate — frequently as much as 1 quart per 1,000-2,000 miles — due to low-tension/stuck oil-control piston rings combined with PCV-system issues that draw oil past the rings. Owners report blue exhaust smoke on startup and acceleration, low-oil warnings between changes, and in severe cases engine damage when the oil level drops unnoticed. GM acknowledged the defect in a 2015 service bulletin instructing dealers to replace the four piston assemblies on affected engines, and nearly 400 NHTSA complaints describe the same failure. A $42M class-action settlement (final approval Nov 2019) covered 2010-2013 vehicles, and a January 2023 suit extended claims to 2014-2017 units.
Low oil level between changes / oil light comes on
Blue smoke from exhaust on startup or acceleration
Burning more than 1 quart per 1,000-2,000 miles
Engine knock or damage if run low on oil
Fouled spark plugs
How to Fix
Have an oil-consumption test performed (documented quart-per-mile measurement) to qualify for goodwill/settlement coverage. The proper repair is replacement of all four piston assemblies with updated rings; clean or replace the PCV orifice and check for carbon buildup. Check oil at every fuel fill as an interim measure to avoid running low. If out of coverage, expect ring/piston replacement or, where the engine was damaged from oil starvation, a long-block replacement.

On the 2010-2017 Chevrolet Equinox, gM's high-feature V6 in the Equinox suffers premature timing-chain stretch, distinct from the covered 2.4L chain issue. Worn chains/guides/tensioners throw off cam-to-crank timing, setting P0008/P0009 (engine position performance) and P0016-P0019 (crank/cam correlation). The classic symptom is a rattle or chain-slap on cold start from the front/passenger side of the engine. Long oil-change intervals and low oil accelerate the wear; left unfixed, a chain can jump time or break and bend valves.
Rattle/chain-slap on cold start from front of engine
Check engine light with timing-correlation codes
Rough idle, hesitation, loss of power
Reduced fuel economy
Possible no-start if timing has jumped
How to Fix
Verify with the correlation codes and a cam-timing check; do not keep driving with active correlation codes. Replace the timing chains, guides, and tensioners as a complete updated kit (both banks on the V6), and change oil on time with the correct spec afterward. This is a labor-intensive repair, commonly $2,000-$3,500.

On the 2018-2023 Chevrolet Equinox 1.5T, the 1.5L turbocharged engine experiences oil leaks near the dipstick tube and PCV valve-related crankcase pressure issues. A faulty PCV valve causes excessive crankcase pressure, which can lift the dipstick tube seal and cause oil leaks.
Replace PCV valve. Reseal dipstick tube. Replace turbo if seals have failed. Clean intake system if oil contaminated. Use shorter oil change intervals (4,500-5,000 miles).
Owner tips & cautions
TipAfter replacing valve cover, check intercooler for oil contamination - failed PCV allows oil into the intake tract

On the 2018-2022 Chevrolet Equinox 1.5L turbo I4 (LYX), on 1.5L turbo (LYX) Equinox models, moisture accumulates inside the charge air cooler (intercooler) and, in cold or highly humid weather, can freeze or pool enough to severely restrict intake airflow. This trips turbo underboost/MAP faults and pushes the engine into 'Engine Power Reduced' limp mode with sluggish acceleration. A related GM TSB also documents the charge air cooler outlet tube separating from the throttle body on 2018-2022 1.5L turbo models, producing the same reduced-power symptom. This is distinct from the known coolant-loss/intercooler-condensation head-gasket issue — here the failure is airflow restriction and boost loss, not coolant consumption.
Inspect and reseat or replace the charge air cooler outlet duct/clamp at the throttle body per GM TSB; clear accumulated condensate from the intercooler; verify the CAC and ducting for cracks. Reprogram the ECM if a related calibration update applies. Some owners drill a small factory-spec weep provision or follow the TSB ducting repair.

On the 2018-2024 Chevrolet Equinox 1.5L Turbo I4 (LYX), because the 1.5L turbo (and the earlier 2.4L SIDI) is a gasoline direct-injection engine, no fuel washes over the back of the intake valves. Over 40k-80k miles, oil vapor from the PCV system bakes onto the valves as hard carbon, restricting airflow and disrupting the seal. Owners report a check-engine light with single- or multi-cylinder misfires that are worst on a cold start, plus a slight loss of power and rougher idle. GM technical document PIP5029E acknowledges misfires caused by 'major carbon build up on the intake and/or exhaust valves.'
Occasional stumble that may not always be felt by the driver
How to Fix
Confirm with fuel trims and a borescope of the intake valves. The definitive fix is walnut-shell media blasting of the intake ports to physically remove the deposits (typically $300-$600). Top-tier fuel and periodic intake/induction cleaners (e.g., CRC GDI IVD, GM Top Engine Cleaner) slow accumulation but will not fully clear heavy deposits. Address any leaking PCV/oil-separator that is feeding oil vapor into the intake, and keep to shorter oil-change intervals to reduce future buildup.

On the 2016-2022 Chevrolet Equinox, the turbocharger wastegate regulator solenoid (and the wastegate actuator linkage) on the turbo engines can stick, weaken, or freeze - moisture and oil condensate can jam the solenoid in cold weather. The result is erratic boost control that trips overboost or underboost faults and throws the vehicle into limp mode with a 'Engine Power Is Reduced' message, sometimes limited to ~15 mph. Testing shows wastegates weakening as early as ~8k miles on hard-used examples. This is a boost-control defect separate from the covered charge-air-cooler condensation issue.
Sudden loss of power, sometimes capped near 15 mph
Erratic or surging boost
Check engine light with over/underboost codes
Worse in cold or humid weather
How to Fix
Scan for boost-related codes and monitor commanded vs. actual boost. Inspect the wastegate solenoid and actuator for sticking/play; replace the wastegate regulator solenoid valve (and, if the mechanical wastegate/actuator is worn, the turbo actuator or turbo). Clear codes and re-test boost. Solenoid replacement is modest ($150-$400); a full turbo actuator/turbo replacement is far more.

On the 2018-2019 Chevrolet Equinox 1.5L turbo I4 (LYX), gM technical guidance documents 2018-2019 Equinox models with the four-cylinder turbo engine running rough and/or stalling on a cold start with the malfunction indicator lamp illuminated. Performance smooths out once the engine warms. The condition is caused by an engine control module software anomaly, with DTC P050D found set/stored in history. Owners experience repeated cold-start stumble, near-stalls, or actual stalls in cold morning starts.
Common Symptoms
Rough running on cold start
Stalling shortly after a cold start

On the 2025-2026 Chevrolet Equinox Electric (Ultium), gM recalled certain 2025-2026 Chevrolet Equinox EV models (and Cadillac Optiq) equipped with optional 21-inch Continental CrossContact RX 275/40R21 all-season tires (RPO QLT). Continental found that tires built during DOT week 4024 (week of October 6, 2024) had inadequate sulfur in the tread-base rubber compound, which can prevent proper adhesion and lead to partial or full tread detachment — raising crash risk. The campaign covers roughly 19,000 Equinox EVs of the ~22,900 total vehicles.
Common Symptoms

On the 2005-2009 Chevrolet Equinox, premature front wheel bearing and hub assembly wear is a common issue on the 2005-2009 Equinox. Owners often first notice a humming or growling noise that changes with speed, followed by ABS or traction control warnings when the integrated wheel speed sensor signal becomes erratic. Because the sensor is built into the hub on many replacements, a failing hub can create both noise and brake/traction system faults.
Diagnosis involves road-testing for bearing noise, checking for wheel play, and scanning ABS data for an intermittent or weak wheel speed signal. The standard repair is replacement of the affected hub assembly, often in pairs if both sides are noisy or high-mileage. After replacement, technicians should verify sensor wiring condition and clear any stored ABS codes.
Owner tips & cautions
TipIf the ABS light appears with a wheel-speed code and there is also a humming noise, inspect the hub first before replacing separate sensors or wiring.

On the 2018-2022 Chevrolet Equinox All engines, owners of third-generation (2018+) Equinox report tires wearing out far ahead of their tread-life rating - some down to 1-2/32 in under 20,000 miles on tires rated for 60,000. Investigations point to out-of-spec rear alignment from the factory (excessive rear toe and camber), which scrubs the tires on the inner or outer edges. A fleet report found 7 of 7 checked vehicles had rear alignment out of spec. Chevrolet has frequently declined warranty claims, calling it a tire-manufacturer issue.
Common Symptoms
Tires worn out well before their mileage rating
Inner- or outer-edge (feathered) tire wear
Wear worse on the rear tires
Vehicle needing frequent realignments
Road noise/vibration from cupped tires
How to Fix
Get a full four-wheel alignment (not front-only) and specifically verify rear toe and camber against spec; correct the rear settings, adding aftermarket rear adjustment cams if the OE range is insufficient. Rotate tires every 5,000-7,500 miles and re-check alignment after suspension work or curb impacts. Alignment ~$100-$200; a set of replacement tires typically $600-$900.

On the 2023-2024 Chevrolet Equinox 1.5L turbo I4 (LYX), owners of 2023-2024 Equinox models with the 1.5L turbo (LYX) report the engine-mounted high-pressure direct-injection fuel pump failing, often well under 60,000 miles (some as early as 28,000 miles). The pump can no longer maintain rail pressure, so the engine suddenly loses power, drops into 'Engine Power Reduced' limp mode (speed limited to roughly 5-55 mph), stalls, or won't restart, frequently leaving the vehicle undrivable and requiring a tow. CarComplaints logged 20 distinct 2023 fuel/propulsion complaints centered on this part, and many owners report the replacement pump being on national back-order for months. This is a separate failure from the earlier 2021-2022 in-tank low-pressure fuel pump module recall.
Engine Power Reduced / limp mode (speed capped 5-55 mph)
Check engine light
Hesitation and loss of acceleration
No-start or vehicle must be towed
How to Fix
Dealer diagnoses low fuel-rail pressure and replaces the high-pressure fuel pump (and gaskets); some cases also require fuel injectors or rail cleaning. Out of warranty, repairs have run roughly $1,000-$1,100. Owners should check for any GM warranty extension or special coverage and verify it is the high-pressure pump (not the in-tank module) before paying out of pocket.

On the 2018-2025 Chevrolet Equinox 1.5L Turbo I4 (LYX), the direct-injection fuel injectors on the 1.5L turbo can leak - internally past a cracked injector body/tip (dumping raw fuel into the cylinder and causing a misfire) or externally past worn upper O-rings (fuel smell, weeping at the rail). This is distinct from the covered high-pressure fuel-pump and in-tank fuel-pump-module failures. GM issued a Customer Satisfaction Program for a fuel-injector leak on some 2025 Equinox that directs dealers to replace all four injectors and the fuel feed pipe.
Diagnose with fuel trims, a misfire counter, and a visual/smell check at the fuel rail. Replace the leaking injector - GM guidance for the 2025 program replaces all four injectors, the rail bolts, and the fuel feed intermediate pipe. For O-ring-only external leaks, new upper O-rings may suffice. Check for any open Customer Satisfaction Program by VIN. Repairs commonly $750-$1,000.

On the 2018-2022 Chevrolet Equinox, a very common 2018+ Equinox complaint: the fuel gauge is wildly inaccurate. Owners report the needle never reaches Full even after topping off (often reading ~3/4), drops or jumps erratically, or hits 'E' with many gallons still in the tank — making it nearly impossible to judge real range. The cause is a fuel-level sender/fuel-pump module that does not seat correctly in the bottom of the tank (insulator pads interfere with sender float travel) and/or sender wiring/ground faults. Dealers have told customers the issue affects essentially all 2018 Equinox/Terrain units, and swapping clusters or senders alone often does not fix it without correcting the module seating.
Common Symptoms
Gauge never reads Full even after the tank is topped off
Needle reads Empty with several gallons still remaining
Reading jumps or drops erratically while driving
Distance-to-empty estimate is unreliable
Problem persists after a cluster swap
How to Fix
Diagnose by graphing fuel-level sender voltage vs. actual fuel added; confirm whether the gauge tracks linearly. The documented correction is to drop the tank, remove the interfering insulator pads from the bottom of the fuel-pump/sender module, and verify the sender float travels its full range and seats correctly. Inspect the sender connector and grounds for corrosion. If the sender card itself is worn, replace the fuel-level sender / fuel-pump module assembly (verify exact PN by VIN). Re-calibrate/relearn if required and road-test from full to confirm accurate readings.

On the 2010-2017 Chevrolet Equinox, equinox models with the GM 6T70/6T75 six-speed automatic suffer shudder, harsh or delayed shifts, slipping, and loss of reverse. A common root cause is failure of the 3-5-reverse wave plate, which can crack and cause extreme shudder when reverse is engaged and eventual loss of drive. Overheated/degraded fluid that loses viscosity accelerates internal wear. Failures typically appear between roughly 60,000 and 150,000 miles. Owners report bucking when engaging gear, failure to shift out of 2nd, and inability to engage reverse.
Service the fluid on a strict interval (and after any overheating). For wave-plate failure, the transmission must be removed and rebuilt with the updated/stronger wave plate; a fluid-and-filter service alone will not fix a cracked wave plate. Verify a current 6T70 software/calibration update is installed to address shudder/shift quality.

On the 2010-2017 Chevrolet Equinox, p0700 is not a standalone defect — it is the transmission control module's way of telling the engine computer to turn on the check-engine light because a more specific transmission code is stored. On the second-generation Equinox, which uses GM's 6T40/6T45 six-speed automatic behind the 2.4L four-cylinder (and the 6T70 behind the V6), P0700 most often appears alongside P0741, Torque Converter Clutch (TCC) solenoid stuck-off. The TCC solenoid is a well-documented weak point across the 6T40/6T45/6T70 family: aged, unchanged transmission fluid lets debris cause the solenoid to stick, so the converter clutch won't lock up properly. P0700 can also accompany shift-solenoid performance codes. Because P0700 itself is generic, the actual fault must be read from the TCM's companion code — treating P0700 in isolation leads to misdiagnosis.
Shudder or slipping at highway speed (TCC not locking)
Stuck in one gear / limp mode
Reduced fuel economy from converter not locking up
How to Fix
Scan the TCM (not just generic powertrain codes) to retrieve the companion code — most commonly P0741 on this platform, or a shift-solenoid code. For a TCC/shift-solenoid fault, drop the transmission pan, replace the affected solenoid (many shops replace the solenoid set while the valve body is out), and service the fluid and filter — fresh fluid alone sometimes frees a mildly sticking TCC solenoid. Verify TCC slip speed returns to near zero when commanded on. If harsh shifting or limp mode is present, address it promptly to avoid further clutch/converter wear.

On the 2018-2024 Chevrolet Equinox, a widespread, heavily-searched complaint: the driver information center displays "Shift to Park" even though the lever is already fully in Park, and the vehicle then refuses to lock, refuses to allow the key/fob to leave, or will not restart. The root cause is an internal park-position microswitch inside the transmission-control (shifter) assembly whose contacts/actuator arm wear out and stop sending the correct low-voltage signal to the Body Control Module. It is intermittent at first (often heat- or vibration-related) and progresses to a daily no-start/no-lock condition. GM addressed it through service bulletins (e.g. PIT5616 series) rather than a recall, and the official repair is replacement of the entire shifter assembly because the switch is not sold separately. The same defect affects the platform-mate GMC Terrain and many other 2014-2024 GM models, which is why owner forums are full of it.
Common Symptoms
"Shift to Park" message displays even though the shifter is in Park
Doors will not lock and the key/fob cannot be removed or detected as leaving
Vehicle will not restart, thinking it is not in Park
Intermittent at first (worse when hot or after a bump), then constant
Battery drain because the car never fully powers down / stays awake
How to Fix
Confirm the fault by checking for the park-switch signal (a scan tool will show the BCM not seeing Park). The GM-approved fix is to replace the complete automatic-transmission shift-control (shifter) assembly (e.g. GM PN 13540931 on 2022+ Equinox; the microswitch is not serviced separately). Many DIYers instead disassemble the shifter and replace/clean the worn internal microswitch. Apply any BCM update per the applicable PIT bulletin. After replacement, verify the DIC clears and the vehicle locks and restarts normally. Budget ~1-1.5 hours labor plus the assembly; aftermarket complete shifter assemblies are far cheaper than dealer OEM.

On the 2024-2026 Chevrolet Equinox Electric (Ultium), in early 2026 GM launched a broad recall covering roughly 102,000 Chevrolet Equinox EVs (primarily 2024-2026 model years) over a vehicle-control / propulsion software defect that can cause an unexpected loss of power or loss of propulsion while driving. Related field reports describe limp-home behavior, propulsion/stability warnings, and in some cases state-of-charge readings dropping suddenly toward zero, leaving the vehicle stranded. A separate GM customer-satisfaction program covers the drive motor power-distribution control module hardware on some Equinox EV and Blazer EV units. Sudden loss of propulsion in traffic raises the risk of a crash.
Common Symptoms
Sudden loss of power / propulsion while driving
Limp-home / reduced propulsion mode
Propulsion or stability warning messages
State-of-charge dropping unexpectedly
Vehicle stranded, may require tow
How to Fix
GM's remedy is a software update (typically dealer-installed, some over-the-air) to correct the propulsion/power-loss logic; the related hardware program replaces the drive motor power-distribution control module and associated parts at no cost. Owners experiencing propulsion or stability warnings should stop driving and schedule service, and verify open recalls by VIN at NHTSA.gov.

On the 2010-2017 Chevrolet Equinox, water and road debris intrude into the windshield wiper module/transmission ball joints, causing corrosion and excessive wear that detaches the linkage and leaves one or both wipers inoperative — a serious safety issue in rain/snow. GM recalled ~367,800 model-year 2013 Equinox/Terrain SUVs under NHTSA recall 16V582000 (Aug 2016), and later recalled 2014-2015 vehicles under recall 22V165 (2022). After an NHTSA investigation found high failure rates on 2010-2012 and 2016-2017 units that were not recalled, GM created Special Coverage Adjustment N192266181 covering wiper-transmission failures for 15 years / 200,000 miles.
Check your VIN against recalls 16V582000 (2013) and 22V165 (2014-2015) at nhtsa.gov; affected vehicles get the wiper module/transmission inspected and replaced free. For 2010-2012 and 2016-2017 models, request repair under Special Coverage N192266181. Out of coverage, replace the wiper transmission/linkage assembly.

On the 2010-2023 Chevrolet Equinox, equinox models are prone to parasitic battery drain where electrical components continue drawing power when the vehicle is off. Common culprits include the OnStar module, radio/infotainment system, interior lights, and stuck relays.
Common Symptoms
Dead battery after sitting overnight
Repeated need to jump-start
Battery fails prematurely (under 3 years)
Infotainment screen going black while driving
Accessories not turning off completely
How to Fix
Perform parasitic draw test to identify culprit. Replace faulty OnStar module. Update infotainment software. Replace radio/infotainment module if drawing excessive current. Install battery maintainer if vehicle sits for extended periods.
Owner tips & cautions
TipCommon parasitic draw sources on Equinox: body control module (BCM) not going to sleep, OnStar module, and radio. A parasitic draw test identifies the circuit.

On the 2018-2024 Chevrolet Equinox, the center touchscreen (Chevrolet MyLink / Infotainment 3) intermittently goes completely black, freezes, or reboots in a loop while the rest of the car operates normally. Owners lose the backup camera, climate display, radio, Apple CarPlay/Android Auto, and OnStar screen. The failure is usually a software/HMI-module fault but is also commonly traced to loose or corroded connectors and cables at the radio receiver located behind/below the glove box, or to a failing HMI (Human-Machine Interface) display module. A temporary fix is a system reboot (hold the power/volume knob ~10-15 s, or hold Home + fast-forward for 10 s), but it returns until the underlying module or wiring is addressed. This is one of the most-searched Equinox electrical complaints across model years.
Common Symptoms
Touchscreen goes fully black while driving but the car keeps running
Screen reboots in a loop or freezes on the Chevrolet logo
Loss of backup camera image, radio, and climate display
Apple CarPlay / Android Auto drops out repeatedly
Screen comes back after a manual reset, then fails again
How to Fix
First attempt the documented soft reset (press and hold the power/volume knob 10-15 seconds, or Home + Seek-Forward for 10 seconds) and let the system reboot. If blackouts persist, inspect and reseat the connectors/cables at the radio receiver behind/below the glove box and check for corrosion or a poor ground. Apply any available GM infotainment software update at the dealer. If the HMI display module itself is failing, replace it with a GM-programmed HMI module (plug-and-play replacements are available and are reflashed to the VIN). Confirm CarPlay/camera/climate all return after repair.

On the 2005-2009 Chevrolet Equinox, a recurring safety complaint on this generation is failure of the passenger presence/occupant classification system in the front passenger seat. Owners report the air bag warning lamp, 'Passenger Air Bag Off' message when an adult is seated, or intermittent operation depending on seat position. The issue is tied to the seat sensor mat/module and related wiring/connectors, and it can disable proper passenger airbag deployment logic.
Scan the SIR module for occupant classification and seat sensor faults, inspect under-seat connectors for tension or corrosion, and verify the system with a capable scan tool after repairs. Depending on the fault, repair may involve connector service, harness repair, or replacement/calibration of the passenger presence sensor assembly. Because this affects airbag operation, proper post-repair verification is essential.

On the 2025 Chevrolet Equinox Electric (Ultium), gM recalled approximately 2,890 model year 2025 Chevrolet Equinox EV all-wheel-drive vehicles (those NOT equipped with Super Cruise) because incorrect brake system control module software can cause the adaptive cruise control system to fail to engage the friction brakes as expected. When a vehicle cuts in front, the Equinox EV may try to slow using regenerative braking torque alone rather than applying the hydraulic brakes aggressively enough, increasing the risk of a collision.
Common Symptoms
Adaptive cruise control does not brake firmly for cut-in vehicles
Vehicle relies on regen braking instead of hydraulic brakes
Insufficient deceleration with ACC engaged
How to Fix
Under recall 25V012000, dealers (or an over-the-air update) install corrected brake system control module software at no cost. Owners can verify by VIN at NHTSA.gov or call Chevrolet at 1-800-222-1020.

On the 2017-2024 Chevrolet Equinox All engines, owners across multiple model years report the factory windshield cracking from very minor rock strikes that would normally cause only a chip, with some drivers on their second, third, or fourth windshield within a year or two. A separate but related complaint is optical distortion/blurriness in the glass that causes glare and, for some, motion sickness, and which often persists even after a warranty replacement. The thinness/quality of the laminated glass is the suspected root cause; there is no recall, but the complaint volume is high.
Common Symptoms
Windshield cracks spreading from tiny rock chips
Repeated windshield replacements in a short period
Blurry/distorted view causing glare or eye strain
Distortion remaining after replacement glass installed
How to Fix
There is no permanent fix beyond replacement. Insist on GM/OEM-spec glass rather than the cheapest aftermarket unit, and on ADAS-equipped trims ensure the forward camera is recalibrated after any windshield replacement (a required step that adds cost). Prompt chip repair (before it spreads) is cheaper than full replacement. Windshield replacement typically runs $300-$500 for base trims and $700-$1,300+ when camera calibration is required.

On the 2024-2026 Chevrolet Equinox Electric (Ultium), multiple recalls address the Equinox EV's exterior pedestrian warning sound (required on EVs at low speed) being too quiet or not varying enough in volume between standstill and creeping speeds, due to incorrect body control module / sound system software calibration. Pedestrians — especially those who are blind or have low vision — may not hear the vehicle approaching, increasing the risk of a pedestrian crash. The campaigns span the 2024 model year (25V639000), 2025 (24V925000), and a large ~81,000-vehicle 2025-2026 campaign (25V878000).
Common Symptoms
Little or no exterior warning sound at low speed
Inconsistent pedestrian alert volume
Vehicle nearly silent when creeping

On the 2018-2021 Chevrolet Equinox 1.5L LYX Turbo I4, the 1.5L turbo (LYX) in 2018+ Equinox is reported to lose coolant with no obvious external leak, leading to overheating and, in some cases, head-gasket failure (coolant entering the combustion chamber). Owners describe the coolant level dropping over time with overheating events. Separately, the early 1.5L turbo had an intercooler/charge-pipe condensation problem in very cold climates where moisture freezes and blocks airflow, triggering reduced-power conditions; GM updated the intercooler and charge-pipe design on later builds.
Pressure-test the cooling system and perform a combustion-gas (block) test to confirm head-gasket involvement when coolant disappears without an external leak. Repair/replace the head gasket as needed and inspect for warpage. For cold-climate condensation/limp-mode complaints, install the updated intercooler and charge-pipe parts. Monitor coolant level and address overheating immediately to avoid further engine damage.

On the 2005-2009 Chevrolet Equinox 3.4L V6, the first-generation Equinox commonly uses the GM 3.4L LA1 V6, and owners have repeatedly reported coolant loss, overheating, and eventual head gasket failure. In many cases the problem starts as an external or internal coolant leak, then progresses to overheating, rough running, white exhaust smoke, or coolant contamination. This issue is well documented in owner complaints and repair discussions for the 2005-2009 Equinox/Torrent platform.
Diagnosis usually includes pressure-testing the cooling system, checking for combustion gases in the coolant, inspecting for coolant loss with no visible leak, and verifying whether the engine has been overheated. Repair typically involves replacing the head gaskets, checking head flatness, resurfacing if needed, and replacing related components such as intake gaskets, head bolts, thermostat, and coolant. If overheating was severe, the cylinder heads or engine may also need machine work or replacement.
Owner tips & cautions
TipDo not continue driving once the temperature gauge spikes; repeated overheating is what often turns a gasket repair into a full engine replacement.
TipPressure-test the cooling system cold and hot, and check for exhaust gases in the coolant before replacing thermostats or radiators blindly.

On the 2010-2017 Chevrolet Equinox, the plastic coolant surge/recovery tank on second-generation (2010-2017) Equinox becomes brittle from years of heat and pressure cycling and develops hairline cracks, most often at the seams or around the cap neck. This causes a slow, mysterious coolant loss with occasional sweet smell and pink/orange residue near the front of the engine, and if ignored can progress to overheating. This is distinct from the 1.5T head-gasket coolant loss and the 3.4L V6 head-gasket leak.
Gradually dropping coolant level with no obvious puddle
Low-coolant warning / overheating
Sweet coolant smell
Dried pink/orange residue on or below the reservoir
Visible crack or seepage at the tank seam or cap
How to Fix
Pressure-test the cooling system to confirm the tank (not a hose, water pump, or radiator) is the source. Replace the surge tank and its cap with a new assembly; plastic-weld repairs rarely hold under pressure. Refill with the correct DEX-COOL and bleed the system. Parts are inexpensive (aftermarket tanks ~$30-$80, GM assembly more); total job typically $150-$400.

On the 2007-2009 Chevrolet Equinox, a known safety issue on later first-generation Equinox models involves corrosion in the brake pressure modulator valve (BPMV), which can cause the ABS to activate improperly at low speeds. Owners report a sudden buzzing pedal, unexpected increase in stopping distance, and the vehicle seeming to roll through a stop on dry pavement. This problem was serious enough to trigger a GM safety recall in salt-belt states.
Diagnosis includes scanning the ABS module, checking wheel speed sensor data, and inspecting whether the vehicle falls under the recall population. The recall remedy involved installing a corrosion-resistant protective coating and, in some cases, replacing the BPMV. If the recall has not been completed, owners should verify VIN status with GM or NHTSA immediately.
Owner tips & cautions
TipCheck recall completion by VIN before paying for ABS hydraulic unit work, because some vehicles were covered by GM's safety campaign.
TipIf the pedal chatters only below about 10 mph on dry roads, inspect the ABS system before replacing pads or rotors.

On the 2018-2022 Chevrolet Equinox, third-generation Equinox (2018-2022) uses a camshaft-driven mechanical vacuum pump mounted at the rear of the cylinder head to supply the brake booster (the turbo intake is pressurized, so there is no manifold vacuum). This pump can seize and its drive gear break, suddenly eliminating brake assist — the pedal becomes 'hard as a rock' with greatly increased stopping distances. In severe cases the pump shatters and sends metal debris into the engine, causing catastrophic internal damage. NHTSA has over 300 complaints; a related GM recall (19V645000) reprogrammed the brake control module on other models but excluded the Equinox/Terrain, and a February 2026 class action (Thieme v. General Motors) targets 2018-2022 Equinox/Terrain.
Common Symptoms
Sudden hard/stiff brake pedal
Greatly increased stopping distance / loss of power assist
Long crank or crank-no-start
Noise from rear of engine before failure
How to Fix
If the brake pedal suddenly goes hard, stop driving and tow the vehicle — continued driving risks a crash and possible engine destruction. Replace the failed vacuum pump (and brake booster if damaged); inspect for metal debris in the engine if the pump came apart. Check VIN for any applicable recall/special coverage and document the complaint with NHTSA.

On the 2005-2009 Chevrolet Equinox, owners of first-generation Equinox models frequently report water intrusion at the rear hatch area, often showing up as wet cargo trim, damp headliner near the liftgate, or malfunctioning rear electrical components. Leaks can come from liftgate seals, body seams, roof rack mounting points, or rear lamp/hatch trim penetrations. Over time, trapped moisture can corrode connectors and contribute to liftgate latch, rear wiper, or lighting problems.
Common Symptoms

musty smell
condensation on rear glass
rear hatch electrical issues
corrosion near rear connectors
How to Fix
Inspect the liftgate weatherstrip, roof rack fasteners, rear body seams, and tail lamp seals using a controlled water test. Repair typically involves resealing seams or penetrations, replacing damaged weatherstrips, drying the interior thoroughly, and cleaning or repairing corroded connectors. If the rear module or latch has already been damaged by moisture, electrical repairs may be needed after the leak is fixed.

On the 2018-2022 Chevrolet Equinox, on Equinox models with the panoramic/power sunroof, the four sunroof drain tubes are prone to clogging with debris or shrinking and popping off the sunroof tray fittings. Instead of routing rainwater/wash water down the A- and C-pillars and out under the vehicle, the water backs up and dumps inside — soaking the headliner, A-pillar trim, front carpet/footwells, rear seat area, and pooling in the spare-tire well. Owners frequently first notice damp carpet, a musty smell, or fogged windows before finding the source. Left unaddressed, the standing water in the spare well can corrode body metal and damage under-floor electrical connectors and modules. This is a high-volume owner complaint distinct from the rear-liftgate leak.
Common Symptoms
Wet carpet or padding in the front or rear footwells after rain or a car wash
Water pooled in the spare-tire well / cargo floor
Damp headliner or water dripping from the A-pillar or dome light area
Musty/mildew smell and foggy interior windows
Intermittent electrical faults from corroded under-floor connectors
How to Fix
Locate and clear all four sunroof drains (front pair exit near the front fenders/cowl, rear pair route down the C-pillars). Owners clear them with low-pressure compressed air or weed-trimmer line and verify flow by pouring water into each corner of the sunroof tray. If a rear drain tube has shrunk and disconnected, peel back the headliner/trim and reseat or replace the tube and clamp. Dry the carpet and padding thoroughly (and treat the spare well for any rust) to prevent mold and corrosion of under-floor connectors. Re-test by flooding each drain corner with water and confirming it exits underneath.

On the 2010-2022 Chevrolet Equinox All engines, on power-liftgate-equipped Equinox, the hands-free/power tailgate frequently stops working - it won't open, opens but won't latch closed, partially opens then stops, or won't hold itself up. Root causes include a failed liftgate latch actuator, a worn strut/drive motor, misaligned position sensors, a corroded wiring harness at the hinge, or a failed liftgate control module (sometimes triggered by a battery disconnect that loses module programming). On some second-gen cars a non-serviceable latch relay inside the underhood fuse block is the culprit.
Common Symptoms
Power liftgate won't open or close from any button
Gate opens but will not latch/close
Gate partially opens then stops
Gate won't stay up (drops)
Beeps/chimes with no movement
How to Fix
Diagnose in order: check the underhood liftgate fuse/relay, verify power at the switch, then test the latch actuator and drive motor and inspect the flex harness at the top hinge for broken wires. Replace the failed component (actuator, motor/strut, or module); a replaced control module or fuse block must be programmed by a dealer/scan tool so door locks and gate function correctly. Repairs typically $300-$800 depending on the part.

On the 2018-2019 Chevrolet Equinox 1.6L Turbo-Diesel I4 (LH7), the diesel Equinox (1.6L LH7) is prone to NOx-sensor and diesel-exhaust-fluid (DEF/SCR) emissions faults. Failing or out-of-calibration NOx sensors and reductant-injection problems set codes such as P11DB (NOx sensor 1 performance) and P249D (closed-loop reductant control at limit), trigger a 'service emissions system' warning with a countdown, and ultimately force the vehicle into a speed-limited limp mode to protect the SCR catalyst. Owners report repeat failures because GM revised the NOx sensors multiple times. A holed/leaking charge-air cooler can also let unmetered air in and mimic the same emissions faults, so the intake must be checked too. This is a high-stakes, expensive emissions issue for the relatively rare but enthusiast-tracked diesel.
Common Symptoms
'Service emissions system' / DEF warning with mileage or speed-limit countdown
Reduced engine power and limp mode at low speed
Check-engine light with NOx/SCR codes (P11DB, P249D)
Repeat NOx-sensor failures after replacement
Increased DEF consumption
How to Fix
Scan and record all emissions DTCs (e.g., P11DB, P249D) and freeze-frame data. Verify DEF quality and the DEF/reductant injector and pump operation, then test the upstream/downstream NOx sensors against live SCR data. Replace the failed NOx sensor with the latest revised GM part for this engine (verify the exact PN by VIN, as GM issued multiple revisions — a wrong NOx sensor will not resolve the fault). Inspect the charge-air cooler and intake for leaks/holes that can trigger the same limp mode. After repair, perform the required relearn/forced regeneration and confirm the countdown/limp-mode clears.

On the 2007-2017 Chevrolet Equinox, p0430 flags the rear cylinder bank's catalytic converter as no longer scrubbing exhaust efficiently. Because Bank 2 only exists on the V6 Equinox (the 3.4L LNJ of 2005-2009 and the 3.0L LF1 / 3.6L LFW/LFX of 2010-2017), this code is effectively a V6-only complaint — inline-4 Equinox models have only Bank 1. On these transverse V6s, Bank 2 is the firewall (rear) bank, whose exhaust manifold and downstream (post-cat) oxygen sensor are the hardest to reach. The ECM compares the upstream and downstream O2 sensor waveforms; when the rear converter can no longer store oxygen, the downstream sensor begins to mirror the upstream sensor and the code sets. On the Equinox the two most common root causes are a lazy/aged downstream (Bank 2, sensor 2) oxygen sensor giving a false reading, and a genuinely degraded rear catalytic converter — the 3.6L in particular has a documented cat-substrate/flange failure pattern (GM TSB 17-NA-321), and its known oil consumption can accelerate substrate poisoning.
Confirm no misfire or fuel-trim codes are present first (fix those before the cat, or a new converter will fail again). Compare Bank 2 upstream vs downstream O2 sensor data on a scan tool — a downstream sensor that switches rapidly with the upstream one indicates a worn converter; a flat/lazy downstream sensor points to the sensor itself. Replace the Bank 2 downstream O2 sensor first when readings are ambiguous (cheaper), and replace the rear catalytic converter if the substrate is confirmed spent. Inspect the rear exhaust manifold and gaskets for leaks, which can also trip P0430.

On the 2010-2017 Chevrolet Equinox, the vapor-canister purge solenoid on the V6 Equinox (and Terrain) commonly fails stuck-open, letting fuel vapor flow into the intake when it shouldn't. This sets DTC P0496 (EVAP flow during a non-purge condition) and sometimes P0455/P0446, illuminates the check-engine light, and can cause a rough/rich idle, hard starting, and even a faint fuel smell. It is one of the most frequently replaced emissions parts on the V6 Equinox because the valve is a known weak point and the repair is cheap and easy. The valve sits on top of the engine and is a roughly one-hour DIY job.
Check-engine light with code P0496 (sometimes P0455/P0446)
Rough or rich idle, occasional stumble
Hard starting, especially right after refueling
Faint raw-fuel smell
Failed emissions/EVAP monitor readiness
How to Fix
Confirm P0496 and inspect the purge-valve vacuum lines for cracks and the connector for damage before replacing. Replace the vapor canister purge valve with the GM/ACDelco OE part 12690512 (supersedes 12610560). After replacement, clear codes and run a drive cycle to confirm the EVAP monitor passes and the light stays off. Also verify the gas cap and EVAP lines if leak codes (P0455/P0446) accompany the purge code.

On the 2010-2020 Chevrolet Equinox, p0442 sets when the ECM detects a small evaporative-system leak — roughly a 0.020–0.040 inch hole's worth of pressure loss. On the Equinox this code follows a clear hierarchy of culprits. The single most common cause across all years is a degraded gas-cap O-ring that no longer seals (or a cap not clicked tight after refueling). On the second-generation 2.4L (LEA/LAF) and V6 models, the next most frequent offenders are the EVAP purge solenoid and the canister vent solenoid, which stick or leak internally. A cause that is distinctly an Equinox/Terrain pattern — especially in salt-belt states — is the metal EVAP line running under the driver's-side frame rail rusting through, which no amount of solenoid or gas-cap replacement will fix.
Hard start immediately after refueling (when purge/vent related)
No performance change; passes as a 'small leak'
May fail emissions inspection
How to Fix
Start with the cheapest, most likely fix: inspect the gas-cap O-ring for cracking/dry-rot and re-tighten until it clicks several times; replace with an OEM ACDelco cap if the seal is degraded. If the cap is good, perform a smoke test — this is the key step that separates a leaking purge/vent solenoid from a rusted-through metal EVAP line under the vehicle. Replace the purge or vent solenoid only if the smoke test localizes the leak there; if the underbody EVAP line is rusted, replace the line rather than throwing solenoids at it. Clear the code and complete a drive cycle to confirm.

On the 2010-2017 Chevrolet Equinox, a well-documented and expensive failure mode: the A/C compressor on the 2010-2017 Equinox platform fails internally and grenades, shedding fine aluminum/metal particles ("black death") that circulate through the entire refrigerant system. Owners notice the A/C suddenly stops blowing cold, sometimes with a grinding/clunking noise or a seized clutch. Because the debris contaminates the condenser, lines, orifice/expansion device, and accumulator, simply bolting on a new compressor causes the replacement to fail almost immediately. A proper repair requires replacing the compressor AND condenser/accumulator and thoroughly flushing the system. This drives repair bills well above a simple compressor swap and is a top owner complaint on these years.
Grinding, clunking, or rattling from the compressor; seized or chattering clutch
Metal/aluminum debris found in the refrigerant or accumulator
Replacement compressor fails shortly after install (system not flushed)
High repair estimate because condenser and lines are contaminated
How to Fix
When the compressor has failed internally, do not just replace it. Replace the A/C compressor and the condenser and accumulator/receiver-drier, replace the orifice tube/expansion valve, and flush all serviceable lines and the evaporator until clean of metal debris. Pull a proper vacuum, recharge to spec, and add the correct PAG oil charge. Compressor part numbers vary by year/engine on this platform (e.g., ACDelco 15-22343 and 15-22276 for 2010-2011, 15-22330 for 2015-2017), so verify the exact PN by VIN before ordering. Skipping the flush/condenser is the most common reason a replacement compressor fails again quickly.

On the 2010-2022 Chevrolet Equinox, the air-conditioning condenser on the Equinox commonly develops refrigerant leaks at its tubes and seals, or from stone-chip damage to the front-mounted core. Because the condenser's internal tubes and seals cannot be serviced individually, a leak requires full condenser replacement. The classic symptom is the A/C blowing warm air, often with an oily, grimy residue visible on the condenser where refrigerant and PAG oil have escaped. This is a frequently reported wear item across multiple model years, especially 2016-2017.
Refrigerant low on recharge / repeat recharges needed
Oily grimy residue on condenser
Reduced cooling performance over time
How to Fix
Perform a dye/electronic leak test to confirm the condenser is the source. Replace the A/C condenser, evacuate and recharge the system to spec, and replace the receiver/drier or desiccant as recommended. Inspect for stone-chip damage and consider a condenser guard in high-debris environments.

On the 2010-2017 Chevrolet Equinox 2.4L I4 (LAF/LEA), on the 2.4L Ecotec Equinox, the catalytic converter is frequently destroyed by the engine's chronic oil consumption (worn piston rings) — burned oil coats and thermally damages the catalyst, setting P0420 (catalyst efficiency below threshold) and the check-engine light. Replacing only the converter without first fixing the oil-consumption root cause leads to rapid re-failure of the new cat. GM acknowledged the thermal/erosion converter failures with Special Coverage 15810, extending coverage to 10 years / 120,000 miles on affected 2010-2011 LAF-engine vehicles. This is a high-demand search because owners face an expensive converter plus the underlying ring/oil repair, and aftermarket "universal" cats often won't clear the code.
Check-engine light with code P0420 (catalyst efficiency below threshold)
Elevated oil consumption preceding the converter failure
Reduced fuel economy and sluggish performance
Rotten-egg/sulfur smell from exhaust
Repeat P0420 after a cheap aftermarket cat was installed
How to Fix
Diagnose P0420 properly (verify upstream/downstream O2 behavior; rule out exhaust leaks and bad O2 sensors). Critically, fix the oil-consumption root cause first — perform the GM oil-consumption repair (piston rings, per the applicable GM oil-consumption PI/TSB) or the new converter will fail again. Replace with a quality OE-grade catalytic converter (cheap universal cats often won't keep P0420 from returning). Check eligibility for GM Special Coverage 15810 (10 yr / 120k mi) on 2010-2011 LAF vehicles for converter replacement. Clear codes and run a drive cycle to confirm the catalyst monitor passes.

On the 2010-2014 Chevrolet Equinox 2.4L I4 (LAF/LEA), the integrated exhaust manifold on the 2.4L Ecotec is prone to cracking, producing a loud ticking/exhaust-leak sound that is loudest on a cold start and can fade as the metal expands. Beyond the noise, the leak can allow exhaust fumes into the cabin and set oxygen-sensor/misfire-adjacent codes. The problem is often aggravated by the 2.4L's well-known oil consumption (a clogged converter raises backpressure) and repeat failures within a couple of years are commonly reported.
Inspect the manifold cold for cracks and check for a leaking manifold-to-pipe gasket and broken/rusted studs. Replace the cracked manifold (or the integrated manifold/converter assembly on federal-emissions cars) with new gaskets and studs. Address underlying oil consumption to protect the new converter. Repairs typically $400-$900 depending on whether the catalytic section is integrated.

Owners describe whining, grinding, or binding from the rear of the vehicle, especially during turns or at highway speed, and some report loss of AWD function. The issue is tied to wear in the rear differential/drive module and sometimes fluid neglect or seal leakage.
Common Symptoms
whining from rear of vehicle
grinding or growling noise
binding during turns
vibration from rear drivetrain
loss of AWD performance
rear differential fluid leak
How to Fix
Diagnosis includes checking rear differential fluid condition and level, listening for rear-end noise on a lift or road test, and inspecting for metal debris or leaks. Depending on severity, repairs range from fluid service and seal replacement to complete rear drive module or differential replacement. Catching the issue early can sometimes prevent catastrophic gear damage.
Owner tips & cautions
TipIf you hear a rear whine on an AWD Equinox, check fluid level and condition immediately; owners who keep driving often end up needing a full rear drive module.
TipConfirm the noise source carefully because worn rear wheel bearings can mimic differential noise.

On the 2005-2009 Chevrolet Equinox, a recurring complaint on first-generation Equinox models is water or coolant intrusion into the passenger-side floor area. Owners report either a leaking heater core/coolant smell inside the cabin or water entering through HVAC case drains and cowl sealing issues, leaving carpets soaked and windows fogged. The problem can lead to mold, electrical connector corrosion under the carpet, and persistent interior odor.
Common Symptoms
wet passenger floor
sweet coolant smell in cabin
fogging windows
low coolant level
damp carpet after rain
musty interior odor
How to Fix
The source needs to be identified first: coolant residue and sweet odor point toward the heater core, while clear water after rain or A/C use suggests a blocked evaporator drain or body sealing issue. Repairs may include heater core replacement, clearing the A/C drain, resealing cowl/body seams, and drying the carpet and underlayment thoroughly to prevent mold and connector damage.
Owner tips & cautions
TipCheck whether the liquid is coolant or plain water before ordering parts; many owners replace a heater core when the real problem is a clogged evaporator drain.
TipLift and dry the carpet padding completely after the repair, because trapped moisture under the carpet can cause odor and electrical corrosion for months.

On the 2005-2009 Chevrolet Equinox, a common first-generation Equinox/Torrent problem is failure of one or more HVAC door actuators, especially the temperature blend and mode actuators. Owners report repetitive clicking or knocking from behind the dash, inability to switch between defrost/floor/panel modes, or heat stuck hot/cold on one side. GM service information and owner reports point to stripped plastic gears or an actuator that loses calibration after battery disconnect or normal wear.
Common Symptoms
clicking or knocking behind dashboard
air only blows from defrost or floor vents
temperature stuck hot or cold
airflow mode changes intermittently
noise starts after key-on or after battery replacement
How to Fix
Diagnose by commanding HVAC mode and temperature changes while listening for actuator clicking under the dash and verifying door movement with a scan tool or visual inspection where accessible. Recalibration can help if the actuator has only lost position, but most cases require replacing the failed actuator and then performing HVAC recalibration. Access can be time-consuming depending on which actuator failed.

On the 2005-2017 Chevrolet Equinox All engines, a clunk, knock, or notchy feel through the steering wheel - most noticeable at low speed, during parking-lot maneuvers, or over bumps - traces to a worn/dry steering intermediate shaft or its universal joints. Rust and lack of lubrication in the shaft's slip joint and U-joints, and sometimes a loose shaft-to-gear pinch bolt, produce the noise where the shaft passes through the firewall to the rack. It is a widely reported, non-safety-critical annoyance separate from the electric-power-steering assist loss and the wiper-transmission ball-joint issues.
Common Symptoms
Clunk/knock felt in the wheel when turning at low speed
Notchy or rattling steering over bumps
Noise near the firewall where the shaft meets the rack
Play detectable at the intermediate shaft U-joint
How to Fix
Have the intermediate shaft and column joints checked for play and the pinch bolt for tightness. Some cases resolve by re-torquing the bolt or lubricating the joint; a worn shaft should be replaced (the second-gen shaft is not always separately serviceable and may come with adjacent components). Typical repair $150-$400.
