My cruise control and brake lights stopped working after having a recall fixed on my 2011 Buick Regal. The recalls that were fixed were an oil life monitor control module and a turn signal control module. After having this fixed, my cruise control and brake lights no longer are working. I was pulled over by a policeman, otherwise I did not know they were not working while I was driving. The brakes will come on once I depress the brake pedal all the way to the floor of the car, but not while driving in normal conditions. I could have been rear ended several times, as there was no indication that the lights were not working.

Purchased car in summer of 2011. During the first cold weather car would give a warning to service stabiliti trac and that the engine power had been reduced. I decided to pull over and restart the vehicle and it would reset the computer and the warning lights would turn off. I took this to the dealer and they could not replicate the issue. I started to let the car warm up in the winter and this seemed to help until recently. Within the last few weeks I have been having similar problems even after letting the car warm up. The car will automatically reduce engine power even while on the highway making it difficult to get out of the way of traffic. After these incidents the check engine light will come on but will go off after turning the car off and restarting. I have contacted onstar and they tell me the same thing that the warning lights do. I have also had issues with the car trying to accelerate on its own while at a stoplight. After going to the dealer and having them not able to diagnose the problem or try to repair it and not fix the issues, I feel at a loss of what to do at this point. I do not have the time or money to keep going to the dealer only to leave with the same problems. I would think that the manufacturer would be more inclined to fix these issue before people are injured or any fatalities occur due to their negligence. I feel that after reading about other people's similar issues that this is something that should call for a recall.

While stopped at a traffic light, the affected vehicle's throttle body failed, causing sever shaking, revving of the engine to approximately 1500 RPM, and eventually causing the vehicle to drive itself forward while my foot was firmly depressing the brake. It propelled, out of my control, approximately 3 feet forward. Had I not put the vehicle immediately into neutral while this was occurring, the vehicle would have travel further, out of my control. Had someone been in front of me at the intersection, or if I had not put the car in neutral, preventing the vehicle from entering the intersection, a vehicular collision would have occurred. The exact cause of the failure, per the dealership work order, was "throttle body internal intermittent short."
