What stands out
Owners have filed 135 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.
Among the 22 model years of Chevrolet Equinox in our records for powertrain problems, this one ranks #2 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This service bulletin informs the technician of an alternate lift procedure that has been developed when the lift plate does not fit the top of the transmission case for 6T30, 6T35, 6T40, 6T45, and 6T50 Transmissions.

full bulletin at NHTSA ↗This service bulletin provides information on some vehicles that may rock or move slightly forward or rearward while in Park at start up after cold soak. This condition may be accompanied by a clunk noise. This is a slight movement that is more often seen visually, rather than felt, when viewed from the outside and using the auto-start feature, if equipped.
full bulletin at NHTSA ↗GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

The failure pattern owners describe
The 2011 Equinox's 2.4L engine and transmission are the core problem. Timing chains rattle early and fail catastrophically, sometimes multiple times despite dealer repairs. Owners discover their engines burning oil at rates requiring quarts every 200–3,000 miles, yet dealers call this normal. When the engine finally starves for oil, it stalls without warning—sometimes repeatedly in the same week on busy roads.
Throttle bodies fail consistently between 50,000 and 60,000 miles, cutting power from highway speed to 20 mph instantly. GM removed this part from powertrain warranty coverage after 2009, leaving owners with $500–$600 repairs despite it being essential for the engine to run. Camshaft solenoids fail and cause stalling; recall 11195A exists, but many owners report their VINs excluded despite having identical symptoms.
Transmissions shatter internally with no warning—the wave plate explodes and fragments circulate through the system, destroying it completely. Repair costs $3,000–$5,000. Some transmissions slip or fail to re-engage while driving. Multiple owners report dealers initially insisting nothing is wrong, then later diagnosing expensive failures. One transmission shop owner confirmed seeing 4–5 of these failures annually on this generation.
Throughout the complaints, owners cite rough idle, metal shavings in oil, cracked exhaust manifolds, and stalling on highways while carrying children. Dealers frequently claim unusual symptoms are normal Equinox behavior and deny warranty coverage despite knowing these are documented defects.

Failure modes owners describe
Timing chain stretch, rattle, and failure
Loose or stretched timing chain causes engine ticking/rattling noise, eventually leading to complete chain breakage that destroys the engine and related components. Owners report loose timing chains that dealers initially claim to have fixed, only for the problem to recur or escalate to catastrophic failure.
When: 10,000–102,000 miles; some cases within 3,600–3,800 miles of prior service
Symptoms owners cite: engine ticking or rattling noise at cold start and while driving; rough or loud idle; reduced engine power messages; check engine light; engine stalling; engine failure with metal shavings in oil
Codes mentioned: P0010 (Camshaft Position Actuator Solenoid), P2135 (Throttle Body)
Repairs/costs cited: Timing chain replacement (often $198–$7,800+ depending on extent of damage); water pump, fuel pump, exhaust manifold, head gasket, and engine replacement required in severe cases
Recalls/TSBs owners mention: GM issued Technical Service Bulletin (TSB) for timing chain issues; some owners reported coverage under a special warranty letter for balance chain repairs, but timing chain repairs sometimes denied as out of warranty or not covered
Excessive oil consumption
Engine burns or leaks oil at abnormally high rates with no external leaks visible. Oil level drops dramatically between changes, starving the engine of lubrication and accelerating wear on timing chain, pistons, and other internal components. Owners report being told oil consumption is 'normal' by dealers.
When: Can begin early (2,000–10,000 miles) and persist throughout ownership; often discovered during oil consumption tests at dealerships
Symptoms owners cite: oil dipstick reading empty or very low 2,000–3,000 miles after change; need to add 1–2 quarts monthly or every 200 miles in severe cases; no warning lights or indicators; rough idle and engine ticking as a result of low oil; excessive heat in engine (cracked exhaust manifold); catalytic converter failure from oil seeping into exhaust
Codes mentioned: Oil consumption test performed by dealers; no specific codes mentioned
Repairs/costs cited: Piston and ring replacement; exhaust manifold replacement (cracked manifolds replaced in 2013 and again in 2018 in one case); owners report denial of coverage citing inability to prove oil-change intervals
Recalls/TSBs owners mention: GM Technical Service Bulletin 15285C issued but coverage denied in some cases on grounds that consumer could not prove 5,000-mile oil-change intervals; Special Coverage Adjustment program exists but owners report inconsistent application and denial
Camshaft position actuator solenoid failure
Intake and/or exhaust camshaft actuator solenoids fail, triggering stalling, rough idle, hesitation, and loss of power. Multiple owners cite recall 11195A for this issue, but some VINs reported as not included in the recall despite experiencing identical symptoms.
When: Around 30,000–71,000 miles reported
Symptoms owners cite: check engine light; vehicle shutting off while driving; stalling at idle in forward and reverse; stalling/hesitation/surging; rough idle; loss of power
Codes mentioned: P0010 (Intake Camshaft Position Actuator Solenoid fault)
Repairs/costs cited: Intake and exhaust camshaft solenoids replaced at no charge under recall 11195A for some; owners reported costs of $500+ for throttle body repairs incorrectly attributed to non-coverage issues
Recalls/TSBs owners mention: Recall 11195A issued for camshaft position actuator solenoids; however, some owners report their VINs were not included in the recall database despite having identical symptoms and matching the recall criteria exactly
Throttle body failure and loss of power
Throttle body sensor or the entire throttle body fails, triggering 'Reduced Engine Power' or 'Service Stabilitrack' warnings and causing severe power loss while driving. Vehicle drops from highway speed to 20–30 mph in seconds with no warning. Issue occurs between 50,000–60,000 miles consistently; GM changed warranty coverage rules, excluding throttle body from powertrain warranty on newer models despite it being covered in 2006–2009 models.
When: 50,000–60,000 miles (consistently reported)
Symptoms owners cite: check engine light illumination; reduced engine power message; service stabilitrack warning; sudden loss of acceleration ability; vehicle dropping from highway speed to 20–30 mph; vehicle unable to turn steering wheel (power steering loss); rough idle and black smoke in some cases
Codes mentioned: P2135 (Throttle Position Sensor)
Repairs/costs cited: Throttle body replacement required; cost ranges $500–$603; entire throttle body must be replaced as sensor cannot be replaced separately
Recalls/TSBs owners mention: GM removed throttle body from powertrain warranty coverage after model year 2009, classifying it under emissions warranty (24,000 miles only); dealers confirm this is now a common problem but decline to cover repairs under powertrain warranty
Transmission failure with internal plate shattering
Internal wave plate or 3-5-R plate shatters suddenly with no warning, sending metal fragments throughout the transmission and destroying it. Vehicle loses ability to move forward or reverse, often while driving on highway.
When: 52,000–109,000 miles; some cases under 100,000 miles (within GM's 120,000-mile special coverage mileage)
Symptoms owners cite: violent shuddering or jerking while downshifting; violent transmission shutter while shifting gears; transmission stops responding to gear selector; vehicle will only move at 10 mph before transmission stops propelling forward; transmission noise (whining, scratching, grinding); tachometer redlining without acceleration; transmission slipping, vehicle rolling backward in drive
Repairs/costs cited: Complete transmission replacement required; cost ranges $2,000–$5,000 depending on warranty package; multiple owners report $3,000–$3,800 out-of-pocket repair costs
Recalls/TSBs owners mention: No warranty coverage offered; dealers and GM refuse to acknowledge design defect or manufacturing defect; transmission shop owner noted seeing 4–5 of these failures per year
Engine stalling due to oil starvation
Engine stalls suddenly with no warning while driving or idling, often caused by excessive oil consumption leaving the engine dry. Oil level monitoring system shows adequate oil remaining when it is actually critically low. Restarting after stall temporarily restores function but problem recurs.
When: Varies; one owner had stalling 3,600–3,800 miles after previous major service; another at 79,621 miles
Symptoms owners cite: engine stalling at traffic lights or while driving at low speed; stalling on busy highways and bypasses; no warning lights before stall; vehicle can be restarted but stalls again shortly after; severe loss of power while stalling
Repairs/costs cited: Engine replacement in severe cases (cost cited as $7,800); oil system inspection and consumption test required
Recalls/TSBs owners mention: GM special coverage adjustment for oil consumption exists but inconsistently applied; some owners denied coverage citing VIN not included or inability to prove proper maintenance intervals
Rough transmission shifts and jerking
Transmission shifts harshly between 2nd and 3rd gear, causing vehicle to jerk or lurch as if being hit from behind. Downshifts are also harsh. Dealers claim this is 'normal' behavior for the model, but owners find it unsafe and unacceptable compared to competitor vehicles.
When: Early in ownership; one owner reported at 12,000 miles
Symptoms owners cite: harsh jolt when shifting between 2nd and 3rd gear; vehicle jerks when accelerating; harsh downshift from 3rd to 2nd like an anchor deployed; transmission delays and slow response to shifts (2–8 seconds reported); hesitation during acceleration and deceleration
Repairs/costs cited: Dealers claim no defect and refuse repair; one owner reported solenoid pack replacement at dealership, but failure recurred
Recalls/TSBs owners mention: Dealers claim this is by design and normal for Equinox; district manager confirmed Chevy designed it to behave this way; no recalls or technical bulletins address this
Transmission slipping and loss of drive engagement
Transmission slips out of gear or fails to engage while moving, causing vehicle to coast or become immobilized in traffic. In some cases, transmission must be placed in park and restarted to regain drive; in others, transmission does not re-engage at all.
When: Under 80,000 miles in most reported cases
Symptoms owners cite: transmission slipping gear while driving; loss of forward or reverse drive; vehicle coasting downhill without power; transmission acts as if in neutral when in drive; loud scratching and rubbing noises from transmission; burning smell from transmission; inability to accelerate despite engine running
Repairs/costs cited: Transmission computer re-flash attempted (only at dealership); full transmission replacement required if re-flash fails; cost $3,000–$3,800
Recalls/TSBs owners mention: Dealers examine vehicle but find no problem in some cases; in others, advise full transmission replacement with no warranty coverage

My 2011 Chevy equinox 4 cylinder shifts horribly between 2nd and 3rd. If you accelerate to approx. 20 MPH and remove your foot from the gas the transmission hesitates and then it shifts to 3rd gear with a jolt that would make you think you were hit from behind. When it down shifts from 3rd to 2nd it is like an anchor was thrown out the back. Returned it to a Chevy dealer who was able to duplicate…
