Our 2022 Yukon Denali is having issues with the electronic parking brake disengaging “releasing” entirely on its own when it definitely should not be. This has happened to us 4X but the dealership cannot replicate the issue when the vehicle is in their possession so they don’t believe us. GM opened a case but simply referred us back to the dealership.
The vehicle was parked on a healthy incline in our neighborhood. The vehicle detected the incline and automatically set the parking brake after the vehicle was set to Park. With the car running and the key fab in the cup holder, my wife got out and opened the rear hatch to unload some items for our neighbor. The vehicle suddenly and quickly rolled back over 6” before the transmission/gearing caught it and stopped it from rolling any further. Our neighbor screamed in shock because she literally thought they were getting run over. Thank god nothing serious happened and nobody was injured.
Why won’t GM or my local dealership do anything to fix this?? This vehicle is not safe to drive!
