What 2017 Buick Regal owners say
Brakes
The contact owns a 2017 Buick Regal. The contact stated that while driving at 70 MPH, the brake pedal was depressed and traveled to the floorboard as the vehicle rear-ended another vehicle. It was unknown if any warning lights illuminated. The contact stated that no injuries were sustained. A police report was filed. The vehicle was towed to a collision repair facility. The contact stated he was unaware of the cause of the brake failure as well as what was repaired. The contact stated that the failure reoccurred in August of 2022 while driving at 70 MPH, the brake pedal was depressed and traveled to the floorboard as the vehicle rolled to a stop. The contact was once again unaware of any warning lights. The vehicle was towed to an independent mechanic where the vacuum brake booster and sensor were replaced. …
Vacuum Pump blew up forcing cam shaft sensor to blew out of engine and caused my brakes to fail. This happened at a stop sign. I proceed through the stop in front of a semi-tractor. Fortunately it was in front of the police station in(30mph) town zone and he was able to brake before killing me. My vehicle stopped before going through the front door of an auto shop, My Timing Cam is damaged and Shepherds is quoting $2600 to replace, plus an additional $800 already spent in replacing the vacuum pump. I've driven the car an additional 6 months with the cam sensor detached but the vehicle stalls when I slow or stop. This has caused additional hazardous situations. Person(s) will die if this defect is not addressed, it's probably already happened. I have over 25 years in Automotive safety systems design and manufacture, this needs addressed immediately.

When i turn the car off the key will not allow me to remove it from ignition to the proper position to remove the key. This is a safety hazzard. I have to mess with the brakes, steering wheel and parking console and keep starting and turning off the car to get key removed. The dealer said they could not locate the problem however several of your other GM vehicles are having this issue. Please assist. I am being stranded in the dark in the cold with a car i cannot leave the key in or someone could steal the car, the doors will not lock with key in ignition.
