My brakes are awful. They sqeak and sqeal constantly. I've taken it to Ken Ganley Buick GMC several times. Prior to that, it was taken to Nick Abraham BMC. The dealerships are able to duplicate the sound and problem over and over again. None of the dealership representatives are able to offer a solution other than paying out of pocket to replace the brake pads because the material the brake pads are manufactured from are falling short. There is no way the brakes are functioning the way they were designed. Thankfully, I have not been in a situation where I need to slam on my brakes but I am not confident that they would do their job in an emergent situation. I have a toddler and a new baby on the way. I purchased a big SUV with the mindset that it would keep my family and I safe. We have leased several GMC products over the years and have never had an issue like this. We will absolutely not be renewing our lease to prove our loyalty to this brand. The fact that I'm being told the only way to fix the manufacturers problem is to pay out of pocket and fully replace the brakes on my vehicle that is 1.5 years old with 28k miles on it, is absolutely absurd. We are willing to give GMC the opportunity to make it right. At this point, I'll be honest, I doubt anything will even be addressed.

As I was stopped in line behind a car at the ATM, my foot slipped from the brake, I quickly placed it back only to find that I ended up going forward. I quickly moved my foot more to the left for the brake only to end up going forward even faster hitting the car in front of me. I then put my left foot firmly on the brake. Now with both feet on the brake the car is climbing up the car in front of me and not braking. Finally, I put it in park and cut the engine. The whole front end of my car is crushed. Now 5 days earlier my husband had a similar incident when he was parking the car and thankfully only hitting the curb. Looking at the brake pedal you will find that there is a rubber edge hanging down on the right side. IF YOUR FOOT SLIPS BELOW IT while crossing from the accelerator going right to left, YOU WILL NOT hit the brake but will continue to press the accelerator. In fact, if you raise your foot upward, you will only raise the brake. The only way to get to the brake is to get out from under it by going toward the accelerator and then back to the left. This action does not work in an emergency! I believe this rubber edge is too large is a safety hazard. We are still in the process of assessment by insurance, body shop and GMC.

Electronic parking brake is setting itself without you doing it even when parked on a completely flat surface. Voice activated assist is going off while driving down the road without you hitting the steering wheel button. 1st dealer I took the car to refused to even address issue because the car didn-??t throw a code even though the parking break issue happened while in their parking lot. 2nd dealer at this point has had the car for a total of 16 days. They tried to tell me the parking break was normal, manager at actual dealership told me it definitely was not normal, and they don-??t know what to do about voice activation going off. It has now been at dealerships 3 times for this issue within Oct and Nov 2021. Only 4,500 miles on car. If it is having these electric issues already what is in store for this car in the future? My husband has a video on YouTube of voice activated assist issue so far 2 other people are saying their cars are having the same issue.
