Charged me for a new battery. Same thing git home started jerking very unsafe. Cleared GM Corporate. They said they would contact the dealership for another assessment. This time they charged me for a Mass Sir Flow repair. Started home. Same exact thing. Called GM today and they said take it back. I said not there. They said for me to tow it to another dealership on my dime. At this point I called the WV State Attorney General’s office. They have no returned my call yet. Please help.

Please help me. I have done everything properly. The car has literally set fire to years now as it’s unsafe to drive. Even had to use rental cars for transportation.

“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.”

“INCIDENT SUMMARY In February 2025, while driving on the freeway, my vehicle experienced a sudden and complete loss of power. The battery rapidly depleted without warning, causing the vehicle to decelerate dangerously in moving traffic. A Stabilitrak warning appeared on the display. I was fortunate to reach the shoulder safely, but this failure created an extremely hazardous situation that could have resulted in serious injury or death. Following this incident, the vehicle became completely inoperable and required towing to Stewart Chevrolet for diagnosis. DEALERSHIP DIAGNOSIS Stewart Chevrolet performed a diagnostic evaluation (cost: $700) and provided the following official findings: Problem Identified: Battery 1 with voltage variance beyond specifications Variance Measured: In excess of 0.07V discrepancy in battery cells GM Document Referenced: #17-NA-131 Recommended Repair: Labor operation 9102972 - Drive Motor Replacement and Shipping Preparation (high voltage battery replacement) Estimated Cost: $10,000-12,000”
