The first time it happened was on the interstate and I had set the cruise control and my speed started to increase slowly at first then it increased at a rapid rate.so I tapped the brake and it disengaged. When I reengaged it the same thing happened. It has happened sporadically and because it happens infrequently I haven't gotten it repaired and when I have asked mechanics about it, they drive it and it works fine.I cant believe I am the only one this has happened to.

For the past few days while driving my security light will come on all of a sudden and the car will lose power and then instantly come back on. I had my 3 children in the car with me so we all were in panic mode when this happened. It has now made me very nervous to drive because I do not want to get into an accident. Friends have told me it was because the chip in my key is worn out and to have a new key made. I contacted a local locksmith and he says since this is happening after the car is in motion then it is not the key. There is something wrong with the ignition switch. I contacted my local Buick dealership and was told there are no recalls on this and it cost $95 just for them to look at it and see how much to fix it.

There are three things that this vehicle cruise control does. First if you try to use the resume feature, it accelerates wildly so you have to hit the brake to disengage it. Second, while driving down the highway with the cruise set at any speed the vehicle will randomly just go to maximum acceleration and again you must use the brake to disengage it. Third and most recent, while driving through town with the cruise on but not engaged, the cruise light comes on and the vehicle takes off at full acceleration all by itself. This is a very dangerous situation and needs to be addressed immediately. GM has no idea where to look other than replacing about $900 worth of parts. In checking on this situation, I found numerous incidents of this same defect with other owners of this vehicle.

The contact owns a 2001 Buick Regal. The throttle became stuck and the vehicle would not slow down until it was placed in neutral gear. The vehicle was towed to a local mechanic who stated that the throttle cable was defective and he should file a safety complaint with NHTSA. The vehicle was traveling at 35 mph when the vehicle suddenly accelerated. The failure mileage was 120,000. The current mileage was 123,000.

I just bought this car. The incident involves the cruise control of this vehicle. I was driving on I-65. I set the cruise for 65 mph. Later, I pushed the accelerate button to increase the speed by 5 mph. I released the switch at the desired speed but the car continued to accelerate as if I floored it. I quickly hit the brakes and that first stopped the acceleration. But as soon as I released the brakes, it went back to acceleration. I then turned the cruise control switch to the off position and that stopped the acceleration. I continued for about 10 miles when I tried the cruise control again. The uncontrolled acceleration occurred again when I used the accelerate button but this time I applied the decelerate button one time as if to decrease the speed by 1 mph. That action killed the cruise control all together. If I wanted cruise control again, I would have to reset the desired speed all over again as if it weren't set at all. I have another incident involving the cruise control on the same trip. I had the desired speed set. When the car hit a bump such as a small pothole, the car's speed suddenly would start to increase as if I floored it. Again I had to apply the off switch or decelerate button to kill it. Another incident occurred on the same trip involving the cruise control. I had the cruise control switch in the on position but hadn't set the speed when I hit a bump on the interstate. Again the car acted as if I floored the accelerator and again I had to turn the switch to the off position or use the decelerate button to stop it. I had this car trouble-shot for this problem. They found that the cruise control module was at fault but the part is on back order nationwide. I was told I could be put on a waiting list but it could be a while. One would have to think I'm not the only one having these problems. I think this is an unsafe condition and should be looked at. Jeff leonard,

2001 Buick Regal experienced stalling. The vehicle also experienced sudden acceleration. The service dealer was unable to find the problem.

I reported this to the Buick dealer once before and they said there was no recall. The cruise control hangs and accellerates. It is all you can do to get it stopped.I quit using it for a long time and tried it again recently and almost rear ended another car.the dealer said they would not even know where to start looking for the problem.

When accelerating the vehicle loses power. The dashboard lights come on, and the vehicle shuts down intermittently. The consumer tried to contact the dealership manager, but the manager refused to discuss the problem. The vehicle would run in high gear and never change gears and would run up to 50 mph before it stops, there were times when the vehicle would run perfectly, there were noises coming from the front end, and when the vehicle pulled out from stop, while in traffic, the consumer would be able to accelerate to the floor and the vehicle would take off at 5 mph.

While driving and applying cruise control at 70-75 mph on freeway vehicle accelarated to higher speed on its own. Please provide any further information, and vehicle identification number.
