I put the car in park and the push button start would not let me turn off my car. I sat in the parking lot almost 30 min, putting my car in park, then drive, then park for my car to recognize its actually in park to turn off. I started getting this error on the start and stop at lights... it never turned off during the start and stop but fearing my life or my families life.... I took it to my local GMC dealership and the manager from the Service department said this is a common issue with this model, he has repaired HUNDREDS of them. His words. This is a safety issue.... I am shocked this has not been recalled. The lack of urgency to get this fixed is very concerning. It costs my $708.92 to fix this issue. I 100% think i am owed this money due to something that should 100% be recalled. …
4-11-22 Wife and I drove from our house to the corner intersection. She put the breaks on and the pedal went to the floor and the car drifted into the intersection, across the street to a parkin lot and then we costed back to our house and had it towed to the local GMC Dealership. Asked for meeting with District Service Manager as I had paid to have vehicle fixed for my use. 5-3 and 4-22 Customer Service in MI agreed that it was a safety issue but out of warranty for brakes. Ok for brakes to go due to wear. 5-16-22 Gave District Service manager (PIE 0458 dated 3-22-18) which reads: "Brake pedal goes to floor with no external sign of a leak" GM KNEW. District Manager helped financially. If we had been in a car crash and died it would have been labeled we ran a stop sigh not that GM willingly put a possible death trap into the publics hands. …
Vehicle will apply breaks abruptly on its own whenever it thinks a vehicle is too close. Was in traffic and it kept slamming on the breaks as I would try and move forward. Will slam on the breaks whenever I attempt to just slow down during the course of driving. Was on the highway and anytime I pressed the breaks to slow down, automatic breaks would slam down breaks on its own. Drove vehicle right to dealership as the was a major safety issue for me especially with my baby in the car.
my car parking brakes will automatically come on while I am driving/ at a light or waiting to turn. I always push the brake pedal all the way down to decompress it and it is still hard to get going. This has put me in very dangerous situations causing my suv to lose power and often times if I am in the middle of a turn it locks up and make it hard to turn. I have took my car to the dealership twice and they have looked at my car and seems to not found a problem
I don't know what is going on with it. I have had it in and out of the shop. My car will randomly throw the parking break on and completely lock my car up. There is no reason why it should be on. The dealership thought it could be the systems needing a update but that didn't fix it. It's a real big safety issue and needs to be looked into. It just did it to me crossing over rail road tracks and I couldn't go anywhere until it decided to unlock.
Something inside the wheel started smoking and my gmc app displayed low break fluid. I pulled over and had someone come out two days later. The breakpad had uneven wear and the caliper had a broken seal on it which in turn tore the caliper up! This was not a safe situation to have with 4 kids in the car. This car has been one problem after another !
Subject of the problem: Service brakes/Hydraulic brakes Problem of the vehicle: While driving, the brake pedal sometimes suddenly goes all the way down without resistance, and the vehicle does not slow down as expected. In order to regain brake pedal twice. Frequency of the problem: This issue occurs intermittently, but it poses a serious risk because the vehicle may not stop when needed. I already had the brake booster kit and hose replaced at an authorized GMC dealership because I was told this was the cause. However, the exact same problem continues to happen after the repair. Safety concern: This appears to be a defect that affects braking performance and safety. The issue occurs intermittently while driving (e.g., at stop lights, low-speed braking, or during normal driving). It has happed multiple times since the repair. …
