2022 Chevrolet Traverse: complete transmission failure

Filed Sep 14, 2026 · Transmission · OK

The transmission failed after picking up my son from daycare. I pulled on to the main road heading home. It started to speed up and suddenly started jerking back and forth causing cars behind me to slam on their brakes and then the car would not go over 15 mph. A few minutes later the check engine light came on and this is the first time it has come on. Called a tow truck and had it towed to a gm dealership they reproduced the issue and told me the transmission is bad and I need a new one because it is a sealed system it cannot be rebuilt. They quoted me $9900 for a new one and also said the transmission is on backorder with no idea when they will be available. They did not say what the labor charge was. This is outrageous for a vehicle that is less than 5 years old.

Wife was driving my kids to school this am. Driving up a slight hill on a speed limit 55 road vehicle started slowing down and wouldn’t accelerate. Stopped for a traffic light and it very slowly accelerated like a manual transmission stuck in a higher gear. Check engine light went on. I Was able to drive the traverse to the local gmc/Buick dealer which mentioned they were able to download some codes about possible transmission failure - super dangerous and very concerning for a ~1.5 year old vehicle with under 13,000 miles. This could be a major safety issue. Vehicle left at dealer, at this time no confirmed diagnosis but dealer acknowledged there’s a problem.
