The engine in my 2014 Chevrolet traverse died. I had only had 53k miles on the engine. This averages to around 10k miles per year, which is below average use. I maintained the car according to the car operating manual with proper maintenance and full synthetic oil changes per schedule all at the Chevrolet dealership. Leading up to my engine dying, the engine started to make some clinking noise,…

What stands out
Owners have filed 35 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 6 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2014 Traverse has widespread powertrain and electrical reliability issues: owners report repeated stabilitrak/traction control failures that shut down the engine at highway speeds with no permanent fix, catastrophic engine seizure at low mileage even with proper maintenance, transmission shifting failures, and cascading electrical faults that dealer diagnostics cannot resolve. Many complaint narratives explicitly state owners found thousands of identical online complaints and no recalls despite years of reported failures.
This cluster reveals a pattern of powertrain failures across multiple systems. The dominant complaint involves the stabilitrak and traction control system: it activates unexpectedly, cuts engine power, and forces the vehicle into limp mode or complete stalling at any speed—from idle to 75 mph. Owners have replaced sensors, throttle bodies, spark plugs, fuses, and even ignition switches, only to have the problem recur within days or months. Dealers cannot identify the root cause; GM refuses warranty claims citing recalls 14187 and 14007 as similar but excludes owners' VINs.
Engine failures appear at modest mileage despite owner maintenance. One owner documented a complete engine seizure at 53,000 miles following a properly-executed full synthetic oil change, with video proof and no low-oil warnings prior. Both the dealership and GM denied the certified pre-owned powertrain warranty.
Transmission complaints include stuck gears, delayed upshifts (especially on hills), jerking between 20–35 mph, and hard shifts. One owner visited three separate mechanics at 140,000 miles without resolution.
Electrical glitches compound the problem: dashboard resets while driving, erratic warning lights, false sensor codes that don't match real faults, and module communication loss (powertrain, fuel pump, OnStar). Some owners note burnt plastic or gear oil smells without leaks.
Unintended acceleration, brake failure, vehicle rollback in Park, and powertrain freeze-ups at any speed round out the safety-critical failures. Dealers consistently state they cannot replicate or diagnose these issues, leaving owners in precarious situations on highways.

Failure modes owners describe
Stabilitrak/Traction Control System Malfunction with Power Loss and Stalling
Stabilitrak and traction control systems activate unexpectedly, triggering 'Service Stabilitrak' and 'Traction Control Off' warnings. Engine power is reduced or cut entirely, forcing the vehicle into limp mode. The vehicle loses forward speed or stalls completely, requiring the driver to shut down the engine, wait, and restart to regain control. This occurs at any speed—idle, highway, or during critical maneuvers—and recurs within days or weeks after repair attempts.
When: Intermittent; occurs while driving at any speed (5 mph to 75 mph), at traffic lights, on freeways, or while parked. Frequency escalates from occasional to every drive.
Symptoms owners cite: Service Stabilitrak and Traction Control Off warnings on dashboard; Engine power reduction or loss of forward speed; Vehicle forced into limp mode; Vehicle stalling while driving; Violent shaking or shuddering of vehicle and steering column; Loss of acceleration control—gas pedal depressed but no speed increase; RPM climbing without corresponding speed gain
Codes mentioned: P1682, C0242, ABS-TCS Brake Switch Circuit malfunction
Repairs/costs cited: Multiple repair attempts documented: sensor replacements, throttle body cleaning, spark plug changes, fuse replacement, ignition switch replacement, and computer updates. Issues recur within days to months. Dealers unable to identify root cause despite repeated visits.
Recalls/TSBs owners mention: Chevrolet Recalls 14187 and 14007 cited as similar by owners but VINs not included in recall scope. GM and dealerships refuse to honor powertrain warranty claims. Service managers state cause could be 'a hundred different sensors' but offer no diagnosis.
Unintended Acceleration and Brake Failure
Engine accelerates on its own without driver input, reaching 6,000 RPM while the vehicle continues to accelerate. Brake pedal depressed but does not slow the vehicle. Occurs during normal driving and at highway speeds.
When: At 25–55 mph during normal operation
Symptoms owners cite: Vehicle accelerates independently without pedal input; RPM spikes to 6,000 while vehicle continues accelerating; Brake pedal depressed but vehicle does not decelerate; Vehicle does not respond to driver control
Transmission Shifting Failures and Delayed Engagement
Transmission fails to shift gears as designed or shifts incorrectly without driver input. Vehicle drags or slips into gears, stays in one gear when it should shift, or fails to upshift on inclines. Acceleration jerks and lags severely, particularly between 20–35 mph.
When: At 25–50 mph during acceleration; documented at 140,000 miles and lower mileage. Also occurs when attempting to climb hills.
Symptoms owners cite: Transmission sticks in gear or fails to shift; Vehicle drags and slips into wrong gear; Delayed upshift; vehicle remains in lower gear; Jerking and popping when shifting or accelerating; Transmission lags on acceleration; Vibration during gear changes; Check Engine light illuminated
Repairs/costs cited: Owner at 140,000 miles visited three different mechanics; problem persists unrepaired.
Recalls/TSBs owners mention: Manufacturer informed; VIN not under recall.
Catastrophic Engine Failure at Low Mileage
Engine seized and locked at 53,000 miles following a routine oil change, despite proper maintenance, correct oil specification (full synthetic), and no prior low-oil warnings. Owner had video documentation of correct oil change procedure. Vehicle was not driven with low oil.
When: At 53,000 miles (approximately 5 years of ownership); engine failure occurred immediately after oil change
Symptoms owners cite: Engine clinking noise prior to failure; Engine seized and locked; No check engine light or low-oil warning before seizure
Repairs/costs cited: Owner possesses video proof of correct oil change procedure and full synthetic oil use per manufacturer spec. Dealership and GM both refused to honor certified pre-owned limited powertrain warranty.
Recalls/TSBs owners mention: Dealership blamed mechanic for 'running engine with no oil' despite video evidence and owner account. GM refused warranty coverage after 5 weeks of contact. Certified pre-owned limited powertrain warranty denied.
Intermittent Electrical System Faults and Module Communication Loss
Vehicle exhibits sporadic electrical anomalies including dashboard resets, warning light cascades, and loss of communication between vehicle control modules (powertrain, fuel pump, OnStar modulators). Symptoms include flickering instruments, false low-battery warnings, check engine lights cycling on and off, and erratic accessory behavior (radio muting, horn honking unprompted, door locks unlocking hours after locking).
When: Intermittent; occurs while driving at low speed (5 mph) or highway speeds. Can persist for weeks, escalating in frequency.
Symptoms owners cite: Dashboard reset while driving—all instruments blink momentarily; Radio cuts off during reset; Multiple warning lights illuminate simultaneously then clear; False low-battery warnings; Check engine light cycles on and off; Traction control light flickers on and off; Horn honks without input; Door locks unlock hours after being locked despite alarm engaged; Burnt plastic smell; Gear oil smell without visible leaks; Dashboard brightness fluctuates
Codes mentioned: P1682, Generic Chevrolet diagnostic codes
Repairs/costs cited: Vehicle remained in dealership shop for extended period without diagnosis. Owner notes pre-certified vehicle still under warranty but repairs not completed.
Recalls/TSBs owners mention: Chevrolet issued computer update recall for some 2014 Traverses, but owner's VIN not included in recall. Owner reports this is a known manufacturer defect but no recall issued to address module communication loss.
Ignition Switch Defect Causing Stalling and Electrical Issues
Ignition switch malfunction causes repeated traction control, reduced engine power, and stabilitrak warnings. Vehicle stalls while driving after warning cascade. Replacement ignition switch provides temporary relief before symptoms recur within months.
When: Since vehicle purchase in 2017; ongoing for years. Vehicle in motion when stalling occurs.
Symptoms owners cite: Traction Control Off warning; Reduced Engine Power warning; Service Stability Control warning; Vehicle stalls while driving; Multiple warning lights cascade
Codes mentioned: Ignition Switch Problem code
Repairs/costs cited: Ignition switch replaced; symptoms resolved temporarily (few months), then recurred. Multiple attempted fixes without permanent resolution.
Recalls/TSBs owners mention: Owner believes Chevrolet is aware of the issue but refuses to recall or provide free repair.
Vehicle Rollback or Unintended Reverse Motion in Park
Vehicle began reversing despite shift lever in Park position. Vehicle came to rest only after striking curb. Occurred at very low mileage (6,000 miles).
When: At 6,000 miles
Symptoms owners cite: Vehicle reversed while in Park position; Loss of parking brake engagement
Repairs/costs cited: Technician unable to locate failure; vehicle not repaired.
Recalls/TSBs owners mention: Manufacturer notified.
Transmission Shuddering, Jerking, and Hard Shifting at Low Mileage
Transmission exhibits rough engagement, shuddering, jerking during acceleration, and excessive noise during shifts. Brake components show accelerated wear (brake pads cracked at 41,000 miles despite adequate friction material remaining).
When: At 41,000 miles; occurs during acceleration and gear changes
Symptoms owners cite: Transmission shudders when shifting; Vehicle jerks during acceleration; Loud noise when accelerating; Rough transmission engagement; Premature brake pad cracking (41k miles); Vehicle hesitates taking off
Repairs/costs cited: Front brake pads required replacement at 41,000 miles; pads were cracked despite adequate material remaining.
Powertrain Freeze-Up and Complete Loss of Motion Control
Wheels, transmission, and powertrain freeze or lock up intermittently for 30 seconds to one minute while vehicle is in motion. Frequency increases over time. Occurs at any speed from 5 mph to 65 mph.
When: Intermittent; escalates in frequency the more vehicle is driven
Symptoms owners cite: Wheels, transmission, and powertrain freeze up; Temporary complete loss of vehicle motion; Loss lasts 30 seconds to 1 minute
Check Engine Light and Sensor Fault Cascade (False Diagnostics)
Check engine light remains on continuously or cycles on and off. Diagnostic scans show multiple false or cascading fault codes including oxygen sensor, air intake, fuel injector, voltage, and brake system faults. These codes do not correlate to actual component failures, indicating the primary fault is a deeper electrical or module communication issue that generates phantom diagnostic codes.
When: At 45,000 miles and beyond; began months before complaint
Symptoms owners cite: Check engine light always on; Check engine light cycles on and off; Oxygen sensor fault code; Low air entrance code; Fuel injector problem codes; Low voltage problem codes; Brake system fault codes; Traction control and stabilitrak warnings accompanying sensor codes
Codes mentioned: Oxygen sensor faults, Air intake faults, Fuel injector faults, Low voltage faults, Brake system faults
Repairs/costs cited: Computerized diagnostic scan performed; owner notes thousands of online claims citing identical cascading false codes. Owner states 'a series of problems with the car which are not real.'
Recalls/TSBs owners mention: No recall issued to address root cause as of complaint date.
Brake Fluid Noise During Braking
Brake system produces a water-like sound during braking application. Symptom present since vehicle purchase and concurrent with acceleration jerking.
When: Since purchase (September 2017); occurs every time brakes applied while vehicle in motion
Symptoms owners cite: Water-like sound when braking; Jerking sensation when accelerating—engine appears to engage unevenly

What owners are reporting 3 most recent
Multiple times the car has just lost power. The dash goes crazy with lights and warnings. Chevy tells me there is nothing they can do because there isn't a code and they can't replicate the problem. Twice I have been driving and this has happened and once when I pulled into a parking spot. Now it does shift really. It revs the rpms, jerks, sputters, and puts while trying to turn or accelerate.…
As I drive down the road the engine acts like its going to stall or as im taking off it jerks
