Service brakes, hydraulic
7 reports1 crash
“The contact owns a 2017 Buick Regal. The contact stated while driving approximately 15 MPH, the braking system suddenly malfunctioned and the brake pedal was firm while depressed, causing the braking distance to be extended. The vehicle was towed to the local dealer who diagnosed that the brake vacuum pump had failed and needed to be replaced. The vehicle was not yet repaired. The contact stated that the failure had previously occurred, and the vacuum pump was replaced by the dealer; however, the failure reoccurred. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was approximately 100,000.”
Service brakes
5 reports1 fire
“Noticed a recall regarding Buick Regal concerning break issues causing the valve to not operate correctly. Possibly the electronic break module not working properly and an update needed along with some parts. Recently the break valve was replaced because the break assist failed. Now, after running the vehicle for more than an hour or sometimes two, the same thing happens. My thoughts are that this affecting more vehicles than just the ones that were recalled.”
Electrical system
3 reports1 fire
“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.”
Power train
2 reports1 fire
“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.”
