The contact owns a 2020 Chevrolet Express. The contact stated that while driving 60 MPH on the highway, the vehicle lost motive power and shuddered abnormally, causing the vehicle to decelerate to 40 MPH. The vehicle was pulled over and restarted; however, the failure persisted. The failure recurred while driving at 40 MPH on several occasions. An independent mechanic was unable to determine the cause of the failure. The vehicle was towed to a dealer, and the contact was informed that the VIN was not associated with NHTSA Campaign Number: 24V839000 (POWER TRAIN); and refused to provide a diagnosis without a visible fractured part. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 98,753.

ELECTRICAL SYSTEM10/23/2025
While driving this cargo van, the driver stopped in traffic to make a left hand turn. In the middle of the turn, the vehicle stalled out and would not immediately start, exposing the vehicle to nearly being hit by the oncoming traffic. When the vehicle eventually restarted, and later brought to a GM dealer for repair, it was discovered that the main ground cable had completely deteriorated. In our fleet of 15 GM vehicles, this is now the SEVENTH vehicle that has needed this main ground cable replaced. This is a serious issue that needs to be addressed.

UNKNOWN OR OTHER,ENGINE10/01/2025
Catalytic converter cracked at exhaust manifold @5 yrs, 34,600 miles. Known problem, denial, scam warranty allowing them to break ‘clean air act’ and scam customers into paying. On the hook myself for a fed law requiring manufacturers repair. At my shop getting fixed when they offered to fix after my mention of fraud! 3 years of claimed-broken welds in vans (doghouse over motor). I know of 4th year problem. Also not believing bad weld.Engineer friend says stress crack. Weak metal, no support due to flex pipe I believe. Cheap parts, money over safety again. And I have proof they do it and deny, misdiagnose, and lie. Criminal I think. Posting online about warranty scam. I was schooled in auto, small business owner. I know law! Given up on gov I’m sorry to say.
