When backing out of a parking spot of a store , I went to stop and pressing on the brakes nothing happened and I kept rolling backwards. I looked down to confirm I was pressing the brakes and my foot was on the brake pedal pressed firmly. I rolled to a stop put it in drive and checked the brakes and they worked like normal. I made an appointment at the dealership and had an appointment the next day. The said it did not have any codes, it preformed normal and passed inspected so there was nothing they could do about it.

Brake module malfunction Codes: “service ESC” “break assist failure. Press hard to break. Speed limited”

Telematic Modular Control is not working properly and part is on backorder. Dealership and GMC have refused to put into writing that my vehicle is safe to drive; however, they are refusing rental vehicle while awaiting arrival of part. Several of my safety features are not working correctly, my left turn signal went out randomly and my auto breaking has activated when there has been nothing near my vehicle.

I got into my car to leave, I placed my phone on the wireless charging pad. When I got to my location about 10 minutes later, I grabbed my phone and went to put the wrist band attached to my phone around my wrist. The wrist band is a metal chain and it burned me on the side of my wrist and top of hand. I took the wrist band off as fast as I could, then touched it with my fingers to make sure that is where the sting was coming form, and it was. The passenger in the car also confirmed that the wrist band was dangerously hot. I took pictures of the burn marks it left on my wrist and hand.

The master cylinder failed under 10,000 miles. I was at 5000 miles. I am reading a lot of people have had issues with the master cylinder in the 2024 early 2025 models. Luckily I was in the driveway barely moving, but man if i were on a highway and it happened it could've been fatal!
