Complaint Summary
FUEL/PROPULSION SYSTEM
Owner Narrative
Since March of 2025 I have identified a critical safety defect with my vehicle. When driving and without warning, the vehicle unexpectedly shifts to neutral, experiences a loss of propulsion, and the engine shuts off. This has occurred multiple times in which I narrowly escaped collisions with other vehicles or objects. If this would occur at a high rate of speed, it would certainly result in serious accident including possible fatality. I have experienced three near-accident scenarios when I had children in the vehicle. I have worked with Classic Chevrolet in Sugar Land, Texas who has made six attempts at repair. They have each time found a different component attribute to an error code and replaced that part. After each visit they tell me that the car is fixed and safe to drive. They have never been able to provide a clear explanation as to why I am experience this reoccurring issue, but attribute it to a different part each time. Within 5 days to 2 months, the incident repeats. I have recent video of the incident that I can share. Chevrolet Customer Care has been minimized my concern and informs me that their Service staff has found the vehicle to be fully operational and safe to operate. I have spent over $6,000 in failed repairs. I do not feel safe operating this vehicle. That list of repairs includes: March 7, 2025 - battery replacement March 28, 2025 - DC/DC power converter April 22, 2025 - ECM updates January 8, 2026 - â¢Throttle body replacement â¢Serpentine belt replacement â¢Engine air filter replacement â¢Transmission fluid flush â¢Coolant fluid flush â¢Fuel injection cleaning â¢Hydrogen carbon cleaning service January 23, 2026 - power control module (recall) January 30, 2026 - rear differential system replacement March 10, 2026 - ⢠Replacement of the high-pressure fuel pump ⢠Replacement of the DC power supply converter ⢠Hydrogen carbon cleaning service I can share all invoices. Chevy is NOT TAKING THIS MATTER SERIOUSLY. Please support
