If you read back on this thread many have been told the same thing. Master Cylinder was replaced and the brakes failed again.

Mine is a 2019 GMC AT4. How did you go about getting the vehicle Lemon lawed?

Going through this exact issue as well. Warnings illuminated at start. Thought I would be able to limp it home. Left my parking spot and had little to no brakes. Had the truck towed to the dealership. They will have had it 7 days tomorrow. To add insult to injury I have a 4" lift on my AT4! I live rurally so most of my driving is 55mph and over on Highways. Does not give me a warm and fuzzy feeling for survival for anyone I hit if my brakes fail at those speeds. Absolutely terrified to put my kids in this truck!! Has anyone found something to fix this? Failed a complaint with NHTSA and opened a claim with GM. My dealership is amazing and doing everything they can but their hands are tied with GM. So it sits!

Certainly looks like that is the same problem! Now to see if that is actually what my dealership did today. The only thing mentioned to me was a voltage issue. They checked my battery and the cable that the problem was supposed to be in and found no issues. Certainly doesn't give me a feeling of comfort when the brakes are what is at stake! I will ask them specifically if they addressed this recall! Thank you so much! Update!!! The recall was performed the Tuesday BEFORE the brakes failed. Well at least I had my hopes up for a minute!

Has anyone actually found a fix to this problem? This just happened to me last Saturday night. Luckily the messages came up at start and I found out I had barely any brakes at 10mph in a parking lot and not on the hwy home! Took me probably 5 feet to stop going 10mph! Towed it to the dealership. The dealership is being told by GM that it is a voltage issue. Everything on the truck checked out fine but now I am scared to death to put my kids in it. The dealership now has it until after Christmas.
