“Issue with the trailer brake system keeps coming up on my dash. I know a lot of other people have had the same issue keeps dinging will not stop causes me to get distracted while driving. Unable to use other features because of this distraction and safety issue. The safety issue needs to be fixed this is an effective product with so many people having an issue you need to do a recall. I did let Graff Chevrolet in Mount Pleasant Michigan no and I took a picture and showed them.”
NHTSA complaint #11748158, filed 2026-07“I had an incident in my 2020 GMC Yukon, where the forward collision crash alert went off and there was total loss of brakes. The brake pedal went to the floor. After the crash alert ended, the brakes returned. This happened on the highway and could have turned into a disastrous event. The dealership has been unable to diagnose or recreate this issue. They claim they did not find anything and the vehicle is safe to drive. I have turned off the collision detection system in the meantime. I feel strongly that this is a software issue that needs addressed. …”
