2017 Chevrolet Equinox Problems: 19 Known Issues

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.

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 12313 (10 years/120,000 miles) for 2010-2011 2.4L (LAF) engines because the chrome layer on the balance chain pins may wear and let the balance chain stretch; it covers the balance chain and fuel pump, not the timing chain.

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.

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.

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.

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, 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.

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.

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.

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.

On the 2010-2017 Chevrolet Equinox, the electronic power steering (EPS) system can fail intermittently or completely, resulting in sudden loss of power steering assist. This creates a dangerous driving condition requiring significant physical effort to steer.

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.

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/LFW of 2010-2012 and 3.6L LFX of 2013-2017), 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.

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.

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.

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.

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.

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.

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.
