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.

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.

THE PAST TWO WEEKS WHILE DRIVING THE VEHICLE, IT SUDDENLY TURNS OFF AND THE BRAKE LIGHT COMES ON FOR THE EMERGENCY BRAKE. IT IS SO SCARY WHEN DRIVING DOWN THE ROAD AND MY VEHICLE SUDDENLY STOPS. I HAVE TO PUT IT BACK IN PARK AND TRY TO GET THE EMERGENCY BRAKE OFF. IT TAKES A BIT TO GET IT OFF. THEN I CAN START IT AGAIN. I HAPPENED TODAY WHILE SITTING AT A RED LIGHT AND WHILE DRIVING DOWN THE ROAD. I WAS ON A CITY STREET.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2017 Buick Regal Tourx verdict →
