What stands out
Owners have filed 30 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 3 years — the issue may be aging out of the active population.
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 bulletin provides information on identifying Non-GM Engine Calibrations for Gasoline Engines using the Tech 2 or GDS 2.

The failure pattern owners describe
The 2017 Equinox powertrain has multiple systemic issues documented across 30 complaints. The most critical is the PCV valve clogging or freezing due to moisture buildup, creating excessive crankcase pressure that blows the rear main seal. Oil dumps without warning—often when the engine dies abruptly on highways—leaving owners stranded in heavy traffic. This exact failure was recalled on 2010–2014 Equinox models, yet GM has not recalled 2017 vehicles despite identical engine architecture. Owners report discovering this is a "known issue" only after failure, with dealerships acknowledging the problem but refusing coverage.
Excessive oil consumption is another widespread complaint, with engines burning or leaking oil weekly or requiring refills between services. Piston ring failures and timing chain breakdowns follow, sometimes occurring under 100k miles with zero advance warning. Transmission slipping, hard shifts, and gear selector failures create dangerous lurching on highways; dealerships repair the same issue multiple times with no permanent fix.
All failures share a pattern: no warning lights until catastrophic failure, repairs exceeding $2,000–$12,000, and warranty denials due to mileage overages or exclusions for PCV-related damage. Owners describe being stranded mid-traffic, nearly rear-ended, and forced into five-figure repair bills on five-year-old vehicles with moderate mileage.

Failure modes owners describe
PCV Valve Failure Causing Rear Main Seal Failure
The PCV (positive crankcase ventilation) valve becomes clogged or frozen due to moisture/ice buildup, creating excessive crankcase pressure that blows the rear main seal. Oil dumps rapidly from the engine. Owners report no warning lights or delayed warnings. Multiple narratives cite this as a known issue affecting older model years (2010–2014) that GM recalled but refuses to recall on 2017 models despite using the same engine architecture.
When: Between 30k and 150k miles; often triggered in cold weather (below zero) or after highway driving. Some occur within months of purchase.
Symptoms owners cite: Sudden low oil pressure warning light (or no warning at all); Visible oil pooling under engine compartment or leaking on road; Engine shuts down abruptly; Reduced engine power or loss of acceleration; Engine shaking or rough idle before failure
Codes mentioned: Low oil pressure indicator
Repairs/costs cited: Rear main seal replacement; quoted repairs range $1,300–$3,200. Some owners report additional damage to timing chains, intake manifolds, and crankshaft requiring full engine replacement ($9,500–$10,000 for remanufactured engine). Extended warranties often exclude PCV-related damage.
Recalls/TSBs owners mention: GM issued 2/4/19 bulletin for PCV valve defect. Recall issued for 2010–2014 model years only; no recall for 2017 despite identical engine/PCV placement. Extended warranty programs typically exclude PCV failures and downstream seal damage.
Excessive Oil Consumption and Piston Ring Failure
Engine burns or leaks oil at an accelerated rate requiring refilling weekly or multiple times between service intervals. Diagnosis varies: piston rings fail, oil consumption device defects cited. Occurs on vehicles with under 50k–100k miles. No pre-failure warning lights in most cases.
When: 30k–100k miles; some issues surface within weeks or months of purchase.
Symptoms owners cite: Oil dipstick reads empty or critically low between services; Blue/white smoke from exhaust; Engine running rough or shaking; Low or no oil warning lights (often absent until seal fails); Reduced engine power warning lights
Codes mentioned: P0016, P0017, P228D, P0089, P0341, Engine power reduced
Repairs/costs cited: Piston ring repair/replacement $2,200–$2,270; full engine replacement $9,500–$10,000. Warranty denials common due to mileage overages (even 600 miles past warranty end) or exclusions for 'normal wear.' One owner paid $2,800 out of pocket after extended warranty refused coverage.
Recalls/TSBs owners mention: No recalls issued for piston ring failures on 2017. Extended warranties often exclude this as non-covered wear. Dealership service departments acknowledge issue but do not proactively address at regular maintenance visits.
Rear Main Seal Failure Independent of PCV
Rear main crankshaft seal leaks or blows oil without obvious PCV involvement. Owners report discovering puddles under the vehicle or rapid oil loss. Repair required to prevent engine seizure.
When: Highly variable: one owner at 150k miles; others report recurring leaks from initial purchase onward.
Symptoms owners cite: Oil pooling in garage or under engine; Visible leak from rear engine area; No warning lights (in some cases); Low oil light when seal fails catastrophically
Repairs/costs cited: Rear main seal replacement $1,300–$1,500. One owner reported leak ongoing since purchase with multiple dealer visits claiming repairs; leak persisted.
Recalls/TSBs owners mention: One CPO warranty covered a transfer case hole (unrelated), but rear main seal repairs typically denied if out of standard powertrain warranty. Dealers sometimes misdiagnose (claiming transmission leak when seal is culprit).
Timing Chain Failure and Bent Valves
Timing chain breaks or stretches, causing loss of engine synchronization. Bent intake/exhaust valves result. One owner reports timing chain issue at 150k miles; another incurred $12,000 repair for broken timing chain and bent valves. Owners cite this as a known issue on the Equinox that Chevy refuses to recall.
When: At or near 100k miles; can occur within 1 year of purchase in isolated cases.
Symptoms owners cite: Engine stalls suddenly mid-traffic; No advance warning lights (or check engine light during/after failure); Rough idle or reduced power before failure
Codes mentioned: P0016, P0017, P228D, P0341
Repairs/costs cited: Timing chain replacement alone quotes not provided; full engine rebuild/replacement $12,000. One dealer offered only $1,200 coverage, leaving owner responsible for $8,657+ out-of-pocket.
Recalls/TSBs owners mention: No recall. Dealerships acknowledge timing chain wear is a known issue but not covered under standard warranty. GM customer service directs owners to dealership diagnosis with no financial assistance.
Automatic Transmission Slipping, Hard Shifts, and Gear Selector Failure
Transmission slips between gears or fails to engage gears smoothly, causing lurching and loss of forward motion. Gear selector sometimes fails to remain in chosen gear (especially reverse), requiring multiple on/off cycles. Transfer case also reports similar failure. Dangerous during highway driving; dealership repair attempts fail repeatedly.
When: 48k–70k miles reported; some issues with no warning signs until sudden onset.
Symptoms owners cite: Hard jolts when shifting between gears (1st to 2nd, 2nd to 3rd); Transmission slipping at stops or accelerating; Loss of forward drive or delayed engagement; Stalling or severe power loss on hills (11–14 mph); Gear selector rolls back into reverse unintentionally (without driver input); Shuddering or shaking at idle
Codes mentioned: Check engine light (no specific codes retrieved in some cases), Service StabiliTrak warning
Repairs/costs cited: Transmission rebuild quoted $5,000 for used transmission; one owner awaiting rebuild in shop queue. Another had transmission replaced under bumper-to-bumper warranty (within original warranty period). Dealership repair attempts (3+ visits) failed to resolve issues; problem recurred within 50 miles.
Recalls/TSBs owners mention: Manufacturer case opened but closed with no remedy for gear selector issue. No recall issued. Bumper-to-bumper warranty covers transmission rebuild if within coverage period.
Transfer Case Failure
Transfer case develops a hole, leaking fluid and causing scraping sounds, smoke, and lurching/bouncing sensation. Covered under CPO extended warranty but parts availability delayed (5+ months cited in one narrative).
When: One report at approximately 5 model years old (2016 vehicle in 2021).
Symptoms owners cite: Scraping or dragging noise from underneath vehicle; Smoke visible in rear-view mirror; Lurching and bouncing during operation
Repairs/costs cited: Repair parts unavailable; one vehicle sat in dealership lot from May through November without parts availability. Dealership offered rental car reimbursement but no timeline for repair.
Recalls/TSBs owners mention: CPO warranty covers part replacement. GM unable to source parts; promised November 2021 delivery did not materialize.
Sensor and Electrical Component Failures
Multiple engine sensors and electrical components fail prematurely (oxygen sensor, catalytic system, accelerator pedal position sensor, VVT solenoids, engine control module faults). One owner had to replace most components; extended warranty excluded coverage.
When: Early in vehicle ownership; one case involved multiple repairs within months.
Symptoms owners cite: Check engine light illumination; Invalid or implausible sensor data; Reduced engine performance; Engine stalling
Codes mentioned: Oxygen sensor codes, Catalytic system efficiency below threshold, O2 circuit low voltage, Accelerator pedal position sensor 1–2 not plausible, Invalid data from engine control module, VVT timing solenoid faults, Fuel rail pressure sensor codes
Repairs/costs cited: One owner replaced oxygen sensor, catalytic converter, accelerator pedal, fuel rail pressure sensors, and multiple solenoids. No costs provided. Extended warranty denied all coverage. Owner currently owes $14k on financed vehicle.
Recalls/TSBs owners mention: Extended warranty purchased at dealership excluded coverage for electrical/sensor failures. No manufacturer assistance offered.

What owners are reporting 1 most recent
I arrived at my workplace. Was there for about an hour, I then went outside to grab something from my vehicle and noticed that I was leaking oil. After further inspection, I realized that I no longer had oil in my vehicle. I had it towed to my service station. After looking at it they called me and said that the PCV had gotten clogged with ice, therefore causing pressure buildup and blowing out…
