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.

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 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 2010-2020 Chevrolet Equinox, transmission shuddering is common in Equinox models, typically caused by torque converter clutch issues or depleted transmission fluid additives. The shudder is most noticeable during light acceleration between 25-50 mph as the transmission shifts through 3rd-5th gears.

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.
Common Symptoms
A/C suddenly blows warm and never cools again
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, 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.
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.

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.

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, 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.
Common Symptoms
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 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 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.

What is the 2010-2017 Chevrolet Equinox 2.4L Ecotec excessive oil consumption (worn/stuck oil-control piston rings)?
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 pa… Repairs typically run $1,500-$5,000. Severity: high.
What is the 2010-2017 Chevrolet Equinox Catalytic Converter Failure (P0420) Caused by Oil-Burning — GM Special Coverage 15810?
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… Repairs typically run $500-$2,500. Severity: high.
What is the 2010-2017 Chevrolet Equinox P0700 — Transmission Fault Flag from 6T40/6T45 TCC Solenoid (Companion P0741)?
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 beh… Repairs typically run $300-$900. Severity: high.
What is the 2010-2017 Chevrolet Equinox 3.0L / 3.6L V6 Timing Chain Stretch Causing Rattle and P0008/P0016 Codes?
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 clas… Repairs typically run $2,000-$3,500. Severity: high.
What is the 2010-2020 Chevrolet Equinox Transmission Shudder and Torque Converter Failure?
Transmission shuddering is common in Equinox models, typically caused by torque converter clutch issues or depleted transmission fluid additives. The shudder is most noticeable during light acceleration between 25-50 mph as the transmission shifts through 3rd-5th gears. Repairs typically run $150-$3,500. Severity: medium.
What is the 2010-2023 Chevrolet Equinox Parasitic Battery Drain and Electrical System Issues?
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. Repairs typically run $150-$800. Severity: medium.
What is the 2010-2022 Chevrolet Equinox A/C condenser refrigerant leak (warm air from vents)?
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 replacem… Repairs typically run $400-$900. Severity: medium.
What is the 2007-2017 Chevrolet Equinox P0430 — Bank 2 Catalytic Converter Efficiency Loss on V6 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 Equi… Repairs typically run $250-$1,400.
