Owners consistently report ignition switch problems—keys that stick and won't turn, switches engaged by accidental knee bumps while driving, and stalls during operation. The recall campaign 14V346000 attempted to address this with replacement key rings and key inserts, but owners say the fix is substandard compared to original equipment and some claim the added key fob weight on the right knee creates medical and safety concerns.
Engine stalling without warning occurs at various speeds, from 3 mph turning into a fuel station to 63 mph on open road. One case involved uncontrolled acceleration after a gear shift that left the driver in the ICU with broken vertebrae. Owners also report electrical fires—two documented cases where parked vehicles caught fire with fire departments confirming electrical system origin.
Other electrical complaints include HVAC blend door failures causing defroster malfunction and windshield fogging (common across multiple owners), backup camera not switching off in Drive mode, radio shutoffs that sometimes disable turn signals, and key fob failures even after recall repair. Several owners mention dealerships being unresponsive or dismissive of electrical symptoms. Parts shortages delayed recall repairs by extended periods, and one owner reported the manufacturer refused help after the recall "fix" failed.
Failure modes owners describe
Ignition switch sticking and not turning
Key sticks in the ignition cylinder and won't turn. Occurs intermittently at different times. One owner reported wheels being straight when problem occurred, contradicting dealer claim that straight wheels are required. Related to NHTSA recall campaign 14V346000.
When: Various times; one owner reported 44,500 miles
Symptoms owners cite: Key won't turn in ignition; Key gets stuck; Intermittent occurrence
Repairs/costs cited: Dealership initially blamed owner's starting technique and steering angle. Remedy per recall was replacement key rings and key inserts for slotted keys—owner reported this as substandard compared to original equipment.
Recalls/TSBs owners mention: NHTSA recall campaign 14V346000 (Electrical System); remedy consisted of replacement key rings and key inserts, which owners criticized as inadequate.
Ignition switch engaging from knee bump
Ignition switch can be accidentally activated by light contact or bumping with knee, causing engine to shut off while driving. Safety hazard because driver loses power steering and braking control.
When: Occurred multiple times while vehicle in use
Symptoms owners cite: Engine shuts off unexpectedly; Loss of power when knee contacts ignition; Vehicle shuts down during operation
Repairs/costs cited: Dealership reported unresponsive to complaints. Owner trained teenage drivers on emergency response, which reportedly saved one driver when failure occurred during their driving.
Recalls/TSBs owners mention: Related to NHTSA recall campaign 14V346000. Some owners reported recall remedy (adjusting driver seat position and adding heavy key fob weight to right knee) was problematic and unsafe.
Engine stalling and loss of power
Engine stalls without warning while driving at low and highway speeds. One incident occurred at 3 mph during right turn into fuel station, causing vehicle to roll into fuel pump buffer. Another at 63 mph with abnormal noise. Reduced power warning light illuminates before stall. Associated with electrical system recall 14V346000.
When: At 38,000 and 58,300 miles; also occurred without known mileage
Symptoms owners cite: Engine stall; Loss of power; Reduced power warning light; Abnormal noise before failure; Stalling control traction light and unknown warning lights; Loss of vehicle control
Codes mentioned: P2138
Repairs/costs cited: One owner reported dealer could not replicate failure even with certified technician test drive. Recall campaign 14V346000 noted but vehicle reportedly had recurring failures post-recall.
Recalls/TSBs owners mention: NHTSA recall campaign 14V346000 (Electrical System). One owner received recall notice; vehicle had recurring failure after recall attempt.
Unreliable accelerator pedal position signal (throttle control)
Accelerator pedal position sensor sends unreliable signal, causing engine derate condition. Related to fuel delivery control. Owner cited GM bulletin 07-06-04-019F and reported ongoing diagnostic trouble code.
When: Unknown mileage
Symptoms owners cite: Engine derate message; Service Stabilitrack warning; Engine power reduction; Unreliable throttle response
Codes mentioned: P2138
Repairs/costs cited: No repair completed; dealer has not confirmed or reproduced failure.
Recalls/TSBs owners mention: GM bulletin 07-06-04-019F cited by owner; no manufacturer action reported.
Uncontrolled acceleration and loss of brake response
After shifting into second gear, vehicle experienced sudden uncontrolled acceleration. Driver reported inability to slow or stop vehicle despite braking and clutch engagement. Vehicle with six-speed manual transmission. Resulted in serious accident with occupant hospitalized.
When: 9/13/2014
Symptoms owners cite: Sudden acceleration after gear shift; No brake response; Loss of vehicle control; Acting like cruise control engaged
Repairs/costs cited: Vehicle declared total loss; owner retained vehicle for investigation and did not release to insurance at time of complaint.
Recalls/TSBs owners mention: No manufacturer response documented; incident may be related to electrical or fuel control system malfunction.
Electrical fire - spontaneous vehicle fire
Vehicle caught fire spontaneously while parked. Fire department determined cause was electrical system. Fire was so extensive it consumed entire vehicle including glass and body panels. Also ignited adjacent parked vehicle, causing total loss of both vehicles. Occurred with brand-new vehicle at 0 miles.
When: Occurred early in vehicle ownership from 0 miles
Symptoms owners cite: Spontaneous fire; Complete vehicle consumption by fire; No prior warning signs
Repairs/costs cited: Both vehicles totaled. Fire department confirmed electrical origin with no foul play.
Recalls/TSBs owners mention: No manufacturer response documented in complaint.
Electrical fire - vehicle fire while parked
Vehicle caught fire while parked at gas station. Engine was off, key removed, doors locked. Fire department determined electrical system as cause. Required fire department response to extinguish.
When: Unknown mileage; occurred after normal operation
Symptoms owners cite: Spontaneous fire while parked and powered off; Complete vehicle fire
Repairs/costs cited: Fire department extinguished fire and determined electrical system origin.
Recalls/TSBs owners mention: No manufacturer response documented.
HVAC blend door failure and defroster malfunction
Temperature blend door (plastic part) fails, resulting in non-functional defroster and inconsistent cabin temperature. Driver side blows cool air while passenger side blows cold air. Windshield becomes fogged causing visibility hazard on highway. Requires dashboard removal for repair, creating high labor costs. Multiple owners report this as common problem affecting many model years.
When: After 11 months of ownership in one case
Symptoms owners cite: Defroster not working; Inconsistent temperature between sides; Windshield fogging; Blinded vision on highway
Repairs/costs cited: Repair requires full dashboard removal due to poor design of plastic blend door component. Labor cost reported as high (one owner cited $4,000 in 11 months). Part itself costs approximately $49 but labor expense makes repair economically prohibitive. Multiple owners indicate this is widespread issue.
Recalls/TSBs owners mention: No recall or TSB documented in complaints; owners requested recall action.
Reverse camera stays on in Drive mode
Backup camera display in rear-view mirror does not turn off when vehicle is placed in Drive gear. Remains on screen, obstructing mirror view. Previously worked correctly, now takes extended time to turn off or fails to turn off entirely. Creates safety hazard as driver cannot see through mirror while driving forward.
When: Deteriorated from proper operation over time
Symptoms owners cite: Camera display stays on in Drive; Cannot see through rear-view mirror; Delayed camera shutoff; Safety hazard while driving
Repairs/costs cited: No repair attempt documented in complaint.
Recalls/TSBs owners mention: No manufacturer response documented.
