Vehicle: 2015 Chevrolet Spark, odometer <79,000 miles Component that failed: Continuously Variable Transmission (CVT) – pulley damage causing complete loss of propulsion.What happened: While driving, the vehicle suddenly lost all motive power with no ability to accelerate. The transmission would not engage in any gear and the car became inoperable in traffic. This is the exact failure described in GM Special Coverage Bulletin N192271110 (pulley damage in 2014–2015 Spark CVT). Safety risk: Complete and unexpected loss of propulsion created an immediate safety hazard. The vehicle could not accelerate from a stop or maintain speed, placing my 15-year-old son and other motorists at risk of rear-end collision or stranding in active traffic lanes.Dealer confirmation: RK Chevrolet in Virginia Beach, VA has inspected the vehicle and confirmed the failure matches N192271110 – full transmission replacement required (quote $6,637.19). Vehicle remains at the dealership and is available for inspection.Warning lamps/symptoms: Check-engine light and reduced-power message appeared at time of failure. No prior warnings before the sudden loss of power event. Failure occurred approximately October 2025 – only four months after GM’s 10-year/120,000-mile Special Coverage N192271110 expired on 06/11/2025.The failed transmission is still in the vehicle and available for inspection upon request.

What owners say
This report concerns a known CVT defect and subsequent TCM failure that left the vehicle unsafe and inoperable. The vehicle suffered internal CVT failure consistent with GM Special Coverage N192271110. After the first transmission failed in May 2024 (and the second time October 5 2025), the TCM failed again shortly after the second failure—consistent with GM Preliminary Information Bulletin PIP5525A. Critical Safety Details: Both failures occurred while driving on highways with heavy traffic, where speed limits were 75 mph. On each occasion, the vehicle lost power and became unable to accelerate safely, presenting a serious safety risk to me and other drivers. GM is refusing coverage despite widely documented cases and their own bulletins describing this exact failure chain.
Vehicle began slipping out of gear between 1st & 2nd, then started losing power at 74,760 miles. Extended service coverage has been issued for model for CVT transmission pulley system, however only covers 10 years or 100,000 miles, whichever comes first. Mine apparently timed out in February, so they are trying to make me get a new transmission which basically totals out the car I spent a fortune on to buy & in repairs at under 75,000 miles. This is unacceptable.
Transmission issue. During heavy traffic at stop lights car wouldn't shift into drive to move forward. Was stuck in the middle of the road with a passenger. Engine light came on but it's not an engine problem. Car was smoking under the hood. I burned my hand when popping the hood. When the car cooled the engine light went out and car would shift gears and it's drivable again. This has happened 3 times. Mechanic pulled up at P0700 Code on computer. It's the CVT transmission but not sure which part. I can't get the car to the dealership to inspect transmission. It won't drive that far.
Whenever I stop at a light and try to move off when the light turn green, I would press the accelerator and the car would not respond for about 3 to 4 mins something with the CVT transmission. This could cause accident on the road.
