What 2011 Buick Regal owners say
Most recent owner complaints, unedited.
While driving on the highway at 60 mph, warning on dash came on saying “engine power reduced” and drop down speed to around 25 mph and I could not accelerate more than 25 mph on the highway which could have caused an accident because of the traffic flow behind me. I put a code scanner under the dash and it read code P2138, Throttle pedal position sensor switch.
The contact owns a 2011 Buick Regal. The contact stated that while driving at 30 MPH, the vehicle stalled with the check engine warning light illuminated. The vehicle was able to be restarted. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 140,000.
The cars mileage was altered due to car being wrecked prior and the other car that was used to replace wrecked parts was hidden and vin number was altered. Copart Inc and ICT Sharp Rides are party's involved, I bought car on 12/28/2023 mileage was listed as 132525
I hit a deer going 60 mph and the airbag didn’t deploy, the service airbag light came on after I hit it. I’d assume that means the airbag tried to deploy but ran into an issue
Driver side headlamp draws moisture, keeps blowing bulbs at 104.99 a pop. Water gets in the headlight assembly and shorts out the ballast. This happens even when driving down the road at random. It could be pitch black and suddenly you have no headlights and are forced to drive with only fog lamps
Preparing to park into a parking space in an off street parking lot the vehicle forcefully and rapidly accelerated on its' own and crashed into a fence. I was not accelerating. I attempted to stop the car using the brakes but they did not engage quickly enough to stop the rapid, forceful, and without warning acceleration. Buick has been contacted about the defect. Buick ran extensive diagnostics on the car and denies there is a defect. Police came to the scene and advised that given the 2 other incidents that I have experienced, the car is unsafe to drive given potential damage to others. A police report was filed.
When pulling into parking space the car rapidly accelerated on its' own and crashed into the car in the next parking space. I did not have my foot on the gas, the car was simply idling. The acceleration was so rapid that applying the brake was useless.
I was parking in marked space. I had turned into space, my foot was off the gas pedal. The car was 3/4 into the space when it malfunctioned and rapidly accelerated into a hardened snow bank. i instantly braked but there was not enough space to avoid collision.
