2015 Chevrolet Spark Engine Problems

The contact owns a 2015 Chevrolet Spark. The vehicle was purchased from a private seller. The contact became nauseated after driving the vehicle for the second time. The contact’s throat, chest, and eyes hurt, and his head was pulsating; the contact was unable to think clearly. No medical attention was received. The contact used an air quality meter to test the inside of the vehicle, which showed "Seriously bad air quality,” but there was no odor inside the vehicle. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the vehicle had not been driven since experiencing the symptoms. The manufacturer was not made aware of the failure. The failure mileage was approximately 59,392.

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.

Transmission slipping since day 1 of purchase of vehicle in 2015. Dealership has stated more than 7 times that nothing is wrong with the vehicle. Vehicle sometimes shuts off, stutters once gas is pressed 95% of the time (from a complete stop). Vehicle transmission slipping is becoming more apparent 2022.
