Vehicle is doing a hard shift from first to second, severe shuddering, sometimes when braking vehicle acts like it wants to surge forward took to a transmission shop I have a bad torque converter and was told this is a problem with the 8 speed transmission from GM. This is a known issue with these transmissions that GM /dealership knew and refuse to fix. The vehicle stalled on me on a road at night where there's no stores, I'm a female alone on a dark road for about 30 minutes trying to get car to start. Luckily it did. This could've caused an accident and my safety was at risk being stranded alone at night. I was told to not drive the car until fixed. I do not have the funds to fix this issue and GM does not respond to requests, Chevrolet is not helping either.

On February 21st at approximately 9:30 AM, I was driving my brand-new 2026 Chevy Suburban High Country when I began hearing an unusual noise from the engine. There were zero dashboard warnings — no check engine light, no alerts, nothing indicating a failure. Out of caution, I immediately headed to the dealership so they could inspect it. I was driving slowly and carefully when, without any warning whatsoever, the engine suddenly and completely seized. The vehicle locked up abruptly. I barely had enough time to try to move toward the shoulder, and I was unable to fully clear the roadway — the rear half of the vehicle remained partially in traffic. It was an extremely dangerous situation. What is especially alarming is that I was not on the highway at the time. Had this occurred while traveling 80–85 mph on SH-130 in Texas — which is a normal speed limit there — the outcome could have been catastrophic. A complete engine seizure at highway speeds could have caused a major accident involving multiple vehicles. Even more concerning, my Chevrolet app (connected through OnStar) still shows no issues or alerts with the vehicle. The attached pictures are from the My Chevrolet app on Sunday, 02/22/2026, around 11:13 AM. This is a brand-new vehicle, and I was informed yesterday that the dealership has requested a full engine replacement. I have no timeline for the repair. For a vehicle of this price point, a sudden engine seizure with zero warnings is deeply concerning from both a safety and reliability standpoint.
