  • 600 miles


This is a 4cyl car with easiest. Unintended acceleration - the car while going downhill or sometimes uphill, accelerates on its own after releasing the gas pedal. I almost hit another car once because of this. Jerking - the car while decelerating from 50-40 mph to 30-20 mph jerks after releasing the gas pedal (with an intention of decelerating) or while applying brakes. This has been happening regularly since I bought the car in Oct 2012.

I have had multiple issues with my 2012 Buick Lacrosse, it started sooner than this with my air deflector falling off at 75 mph and almost flipping my car. This time on July 30th my vehicle went completely out from the memory loss, the transmission just stopped working and I was stalled in one of the busiest intersections in my city. As I was trying to get my vehicle to move again the light turned red and an 18 wheeler almost broadsided me. I found out that back in may a safety recall was sent down on my vehicle. The ones with easiest the battery in the back can catch fire and cause problems. I did not even get my notice until I had picked my vehicle up and GM said they weren't going to send notices until they "had a problem" well parts on national back order due to the problem seems like a huge problem. GM keeps giving me excuse after excuse and does not want to help me in all the problems I have had. My air deflector falling off they said could not happen, I said it did and it is gone, can't reproduce something with nothing there. In front of my neighborhood a Cadillac escalade dropped his air deflector too, same side dropped, same side twisted off, nothing in the road to cause the problem and I have the proof yet GM doesn't care and still says it doesn't happen. My mechanic said if it is not installed properly they will just fall off, the air deflectors on GM products are held on by only 2 bolts, the other spots have never been bolted on, now I have a damaged vehicle and GM says it doesn't happen. I have almost been killed three times and my daughter once in this vehicle, how normal is that? please help!!

After starting engine and placing gear in drive, the car accelerated on its own so fast that it left tire marks on the pavement from where the acceleration started. The car passed through the parking lot lane, over two curbs, slightly scraping a small post in the parking lot causing the damage to the right side of the car. After trying to stop the car by applying the brakes and shifting to neutral and the car running over two curbs and steered into bales of hay which helped bring the car to a stop, shut the engine off and got out of the car. The car was towed to the Buick dealer and Buick div. Was informed and the following is the number assigned to the case by Buick: [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The contact owns 2012 Buick Lacrosse hybrid. The contact stated that while driving 5 mph and attempting to park, the vehicle suddenly accelerated to 100 mph and crashed into a wall. The vehicle was destroyed and the contact suffered injuries to the back, hands, shoulders and hip. The contact was transported to the hospital. The first respond stated that the cruise control was activated at the time of the crash, which deactivated the braking system and caused the vehicle to accelerate without warning. The contact did not call the manufacturer. The failure mileage was 190. The VIN was not available.

Driver was on a large freeway in traffic, when the accelerator pedal broke off. Driver obtained control of the vehicle but not before the car surged into the vehicle in front of it. The pedal completely broke off and was laying in the floorboard. Car was purchased brand new and had only been driven for 6 months. Car was towed to dealership where purchased and is being investigated to determine the case of the pedal failure. No answer yet.
