What stands out
Owners have filed 78 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA powertrain complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2012 Chevrolet Equinox powertrain is troubled by chronic excessive oil consumption, timing chain failures, stalling in traffic, and hard transmission shifts—issues GM was aware of but did not adequately recall or warn about. Engine replacement, transmission repair, and repeated visits for unresolved faults are common, and warranty coverage is often denied once the powertrain warranty expires, leaving owners with thousands in unexpected repair costs.
The 2012 Equinox powertrain complaints cluster around two interdependent failures: oil starvation and transmission dysfunction. Owners consistently report the engine burning through a quart of oil every few hundred miles with no low-oil warning light to alert them. This oil loss—traced to bent piston rings by some mechanics—allows the timing chain to stretch, skip, or snap, sometimes before any check-engine light appears. Stalling in traffic is widespread, happening at stops, intersections, and even highway speeds without warning. Many owners spent $1,400+ replacing O2 sensors, catalytic converters, and camshaft solenoids only to find the stalling persists.
Transmission problems include violent downshifts that feel like rear-end collisions, hesitation from a dead stop, and lurching into neutral during motion. Dealers often claim inability to reproduce these defects, leaving owners stranded with no remedy despite multiple visits.
GM issued service bulletins and special oil-consumption policies for 2010–2011 models but excluded many 2012 vehicles, even when symptoms matched exactly. The extended warranty and recall coverage did not transfer reliably to the 2012 generation. Owners discovered class action lawsuits already underway online, only to have claims denied because they had not completed the time-intensive oil consumption test—a process the company itself controlled. The safety risk is acute: vehicles stall in busy intersections, fail to accelerate when merging, and offer no warning before engine shutdown.

Failure modes owners describe
Excessive Oil Consumption & Timing Chain Failure
Engine burns oil rapidly despite regular maintenance, often with no low-oil warning light activation. Oil escapes through bent piston rings, coating internal components. Inadequate oil supply causes timing chain stretch, jump, or snap, and camshaft actuator/solenoid failures. Multiple owners report engines requiring complete replacement or catastrophic seizure.
When: Typically 48k–120k miles; some failures occur early (under 50k)
Symptoms owners cite: Low or absent oil despite regular changes; No low-oil warning light; Engine bucking, rough idle, stalling; Knocking or rattling from engine; Oil in tailpipe or visible burning; Timing chain stretch or skip detected; Camshaft actuator solenoid malfunction; Check engine light with stall events; Reduced engine power warnings; Sputtering and loss of power during acceleration or idle
Codes mentioned: P0300 (multiple misfires), P0335 (crankshaft position sensor), P0016 (cam/crank misalignment), P0101 (mass airflow sensor), P0128 (coolant temp malfunction), P0304 (cylinder 4 misfire), P0404 (EGR), Various O2 sensor codes
Repairs/costs cited: Engine replacement: $5,100–$10,000+ (owner cost varies; warranty typically covers 30% or denies after expiration). Timing chain replacement: $1,600–$2,000+. Camshaft actuator solenoid: $200+. Fuel pump replacement: noted in some cases. Owners report multiple trips and part replacements (sensors, actuators, chains) without resolving root cause.
Recalls/TSBs owners mention: GM issued oil consumption special policies (TSB/SCA 12313B, 12313D, 13-06-01-003F, 13-06-01-003H) for 2010–2011 models, offering extended warranty or partial coverage. 2012 models not consistently included. Service bulletins PI0562, PI0202A, PIP4716, PI0469, PIP4112Q issued but do not guarantee repair or recall applicability. Oil consumption test process lengthy (months, multiple visits) and diagnostic fee ($150) sometimes charged. Class action lawsuit denials cited due to lack of documented oil consumption test completion.
Transmission Hard Shifts, Lurching, & Loss of Power
Transmission shifts violently or hesitates, lurches forward on acceleration, or goes into neutral during driving. Vehicle may not respond to accelerator input, causing dangerous slow-speed or no-speed conditions in traffic. Intermittent nature makes dealer diagnosis difficult. Transmission control module (TCM) failure reported in some cases.
When: Intermittent; can occur from early ownership through high mileage (30k–122k miles reported)
Symptoms owners cite: Violent or hard downshift at 14–18 mph; Hesitation or lurching on acceleration from stop; Transmission slams into low gear without warning; Vehicle goes into neutral during motion, coasts; No forward movement when accelerating from stop; Transmission does not upshift smoothly from 1st to 2nd gear; Transmission flashing 'R' or 'D' on display; Vehicle sluggish and unresponsive to throttle; Hard clunking noise when shifting into Drive
Codes mentioned: P0700 (transmission control system malfunction), P069E, U0073, U0100
Repairs/costs cited: Dealers often cannot duplicate problem. Transmission replacement recommended at $3,000–$4,000+. Intake solenoid replacement: noted. Some owners report trading vehicle in rather than repair due to cost. Temporary fixes via power cycle (key off/on) reset the system briefly.
Recalls/TSBs owners mention: Service bulletin PIP4112Q issued, stating condition is 'normal' or due to aggressive acceleration (not matching owner experience). Dealers unable or unwilling to perform warranty repair due to inability to reproduce. No formal recall identified in narratives for this failure mode; owners directed to trading vehicle in.
Stalling in Drive, at Stops & in Traffic
Engine cuts off without warning while vehicle is in Drive at red lights, during slow-speed traffic, or while backing up. Restart is usually possible but vehicle may stall again within minutes. No warning lights in many cases. Creates immediate hazard in busy intersections and highway traffic.
When: Intermittent; reported from early ownership to high mileage (50k–122k miles). Some events clustered in first few months.
Symptoms owners cite: Complete engine shutdown while in Drive; No check engine light or warning preceding stall; Vehicle stalls when slowing down or coming to stop; Stalls repeatedly in quick succession (2–4 times per drive); Stalls while backing up; Stalls on highway in stop-and-go traffic; Steering wheel locks when stall occurs; Check engine light may illuminate after stall; Vehicle restarts but stalls again shortly after
Codes mentioned: P0300 (random misfire), P0335 (crankshaft position), Various misfire codes
Repairs/costs cited: Dealers often cannot reproduce issue. Intake camshaft actuator solenoid replacement sometimes performed ($200–$300 range). Tune-ups, O2 sensor replacement, catalytic converter replacement reported as attempted fixes without resolution ($1,400 spent in one case with no result). Some owners perform neutral shift at stops as temporary workaround. Multiple visits to dealership reported without permanent fix.
Recalls/TSBs owners mention: Service bulletins issued (PI0562, PI0202A, PIP4716, PI0469) for 2011 models, not consistently applied to 2012. Owners note same issue persists in 2012 model despite bulletins. No formal recall for stalling identified. One owner cited Recall #11195 and #12312 as related to 2011 model.
Rear Main Seal Failure
Rear main seal breaks or leaks, often triggered by cold weather. Root cause identified as defective PCV (positive crankcase ventilation) system. Service bulletin issued with special coverage, but VIN exclusion prevents many owners from receiving warranty coverage despite having identical symptoms.
When: Reported in cold weather conditions; some cases around 5–6 years ownership
Symptoms owners cite: Oil leak detected at rear of engine; Leak becomes apparent in cold weather
Repairs/costs cited: Repair cost not specified in narratives. Service bulletin indicates replacement of affected seal and PCV system components.
Recalls/TSBs owners mention: GM Service Bulletin (SB-10057977-8108) issued for special coverage; however, published list of 'impacted VINs' does not include all affected vehicles. Owner unable to view complete VIN list and dealership denies coverage despite vehicle matching symptom description. Coverage is case-by-case and relies on dealership interpretation of incomplete data.
Engine Power Loss, Reduced Power Mode, & Electrical Shutdown
Vehicle enters 'reduced engine power' or limp mode, limiting speed to 30 mph or less. In severe cases, all electronics (radio, power steering, air condition, screen) shut off simultaneously. Engine loses responsiveness and may sputter or hesitate. Often triggered by low oil or sensor failures related to oil contamination.
When: Variable mileage (25 mph incident to 112k miles reported)
Symptoms owners cite: Reduced engine power warning appears on dash; Vehicle speed capped at 25–30 mph; All electronics shut off (power steering, AC, radio); Engine sputters or hesitates before loss of power; Service StabiliTrak light illuminates; Check engine light on; Dashboard gauges erratic (speedometer up and down, ECO light flashing); Engine unable to accelerate
Codes mentioned: P069E, P0700, U0073, U0100
Repairs/costs cited: One case involved fuel pump leaking into crankcase; timing chain replacement performed. Another required ECM board replacement due to oil contamination. Actuator replacement attempted in one case without resolution. Root cause often traced to oil-related contamination of sensors and electrical components.
Recalls/TSBs owners mention: Dealer investigation noted in one case (2010–2011 bulletin 12313B describes fuel pump issue as known defect). 2012 model not covered under special extended warranty even when identical symptoms present.
Engine Failure (Complete Seizure or Catastrophic Damage)
Engine seizes suddenly or experiences catastrophic internal damage (holes in block, blown pistons, melted components). Typically follows period of low oil or oil contamination. Vehicle may lose power on highway at speed. In one case, fire erupted under vehicle.
When: Under 70k miles; some failures under warranty expiration window
Symptoms owners cite: Complete loss of power while driving; Knocking sound prior to seizure; Black smoke and flames underneath vehicle (one case); Engine will not restart or turns over without combustion; Large visible holes in engine block discovered post-failure
Repairs/costs cited: Engine replacement or teardown diagnostic required ($750–$10,000+). One vehicle totaled due to fire damage. Warranty coverage denied once vehicle exceeded mileage limit (warranty ran out 5 months before failure in one case). Dealership diagnostic fee ($750) charged to owner to investigate cause.
Recalls/TSBs owners mention: Warranty denial common once powertrain warranty expires (typically 5 years/60k miles). Class action lawsuit claims denied due to lack of documented oil consumption test. One case (fire): GM warranty investigation 'totaled' vehicle but customer service declined replacement assistance.
Unexpected Vehicle Movement in Park
Vehicle rolls or moves while in Park with keys in ignition and engine off. Reported incident resulted in owner being crushed under vehicle.
When: Parked, engine off, keys in ignition
Symptoms owners cite: Vehicle rolls backward while parked
Repairs/costs cited: Related to NHTSA campaign 16V502000 (Electrical System, Power Train). Physical injury sustained (5 broken ribs, punctured lung, infection).
Recalls/TSBs owners mention: NHTSA campaign 16V502000 issued; however, owner's attempts to contact GM CEO and general counsel went unanswered.
High-Speed Engine Rev & Loss of Control
Engine revs uncontrollably to high RPM when accelerator is applied or during normal operation. Engine continues to rev even after brakes applied and vehicle shifted to Neutral or Park. Creates hazard if loss of control occurs during highway merge or heavy traffic.
When: Intermittent during driving
Symptoms owners cite: Engine revs rapidly and uncontrollably; Engine rev continues after brakes applied; Engine rev continues after shifting to Neutral or Park; Required engine shutdown to reset condition; Vehicle red-lines at 6,000 RPM before banging into gear
Repairs/costs cited: One case: dealer towed vehicle and performed investigation; vehicle was at dealership at time of report. Another case: vehicle red-lining and hard gear engagement ongoing for months; dealer repeatedly unable or unwilling to resolve despite multiple visits and on-going warranty coverage.
Recalls/TSBs owners mention: Transmission control module and powertrain control module updates applied in one case; dealer could not guarantee repair would remedy failure.
Faulty Oil Level Warning System
Low-oil warning light fails to illuminate when engine oil is critically low or depleted. Owners often discover near-bone-dry oil only after engine damage occurs or during routine maintenance visits.
When: Occurs throughout vehicle ownership, especially in vehicles with high oil consumption
Symptoms owners cite: No low-oil warning light despite critically low or absent oil; Oil found to be bone-dry or dangerously low during check; Multiple oil additions required between changes; Oil viscosity/condition degrades rapidly
Repairs/costs cited: Warning system malfunction or sensor failure inferred; no specific repair procedure cited.
Recalls/TSBs owners mention: GM issued letter 16118 instructing owners to have vehicle towed to dealership if knock/rattle heard, and to begin oil consumption test. However, test process is lengthy and does not prevent engine damage during wait period. No recall issued to address warning light failure.

What owners are reporting 3 most recent
Briefly, for the last month and a half I have experienced rough idle on start and rough idle & stall with the car losing power and going dead at red lights and in traffic while in drive. I took the car to the auto mechanic and stored codes suggested replacing o2 sensors, the catalytic converter and a tune-up would resolve the issue; I replaced all of the above to the tune of 1400.00; the issue of…
