Brake Disc Pads problems of the 2016 GMC Sierra 1500

Tl the contact owns a 2016 a GMC Sierra 1500. While driving 65 mph, the vehicle started wobbling. The vehicle was taken to wallingford Buick GMC (1122 old north colony rd, wallingford, CT 06492, (203) 269-8741) where the brake pads on the front driver's side wheel were replaced; however, the failure recurred. The vehicle was taken back to the dealer and test driven. The technician diagnosed that the rotors needed to be resurfaced, the front brake pads needed to be changed, the transmission fluid needed to be drained, and the computer needed to be reset. The contact retrieved the vehicle and the failures recurred the following day. The dealer advised the contact to give the vehicle a few thousand miles to work out the failures and stated that the transmission was adjusting to the contact's driving habits. The vehicle was not repaired again and the failures were still present. The failure mileage and VIN were unknown.

This issue began last year in Nov. 2018. We were in traffic and stopping and going until we couldn't stop and the brake pedal was to the floor and the car was still moving. We brought the truck to the dealer and they said it was the brake pads. We payed $1700 to replace all the pads. The other day (3 months with the new brakes) the issue happened again and the truck wouldn't stop, almost causing an accident that could have seriously injured the elderly lady in front of us and ourselves. This issue is getting worse and presents a hazard to us and everyone on the road. This issue occurs at random times, slowing to get off an exit ramp, in traffic, stopping for cross walkers, etc. We brought it to the dealership and they require us to reenact (putting everyone in danger) the issue and until they experience it, they won't fix it. Leaving us with a car that doesn't stop that will sooner or later cause an accident.

Brakes failed completely at low to moderate speeds both going forward and in reverse. Brake pedal went flat to the floor and the vehicle failed to stop. Initially occurred November 7, 2018 and has periodically recurred since then. As of March and April 2019 it has begun to recur more frequently. After the initial occurrence I took the vehicle immediately to the dealer. They could not replicate the problem and took no corrective action. They did recommend replacing the front brake pads and machining the rotors, which I had them do. Mileage was 44,522 at that time. It is back with the dealer today and the focus seems to be the brake vacuum pump. Of course, the vehicle is now out of warranty so I'm waiting to see if they will perform the repairs at GMC's expense or not. If not, I will likely begin contacting other owners to create a group large enough to initiate a class action lawsuit.

Several times I've experienced weak braking a different speeds or while shifting from parking. I also experience the brakes not fully depressing after I step on the brakes. I took my vehicle for a brake inspection thinking I may need new brakes and was told by the inspector that the pads are not the issue, he told me he has never seen an issue similar to what is going on with my truck and instructed me to take it to the dealership. When I contacted the dealership the service advisor told me that it sounds like I just need to replace the brake pads and rotors and told me that he doesn't believe there's an underlying issue based on what I was told at the other service center. Any issues with braking components should be addressed immediately by the manufacturer before people get hurt or someone is killed.
