2001 Buick Regal: adaptive cruise control problems

Filed Dec 14, 2014 · Acceleration · 52,000 miles · MI

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.

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 $900.00 worth of parts. In checking on this situation, I found numerous incidents of this same defect with other owners of this vehicle.

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. *tr jeff leonard,

I own a 2001 buick regal that I bought new, it has 27,000 original miles. Two years ago when I engaged the cruise control and the car accelerated on its own. Now whenever the cruise control is engaged sometimes it works at first and then later it may start accelerate until you hit the brakes to disengage it.

Cruise control only works intermittently and sometimes operates normally for a period of time then accelerates very rapidly unexpectedly. I have not returned to a dealer yet but thought the incidents important to report.

Our 2001 buick regal lost it's a/t at 40,300 miles, locked out of reverse, gears 1 & 2. Only had drive-3. Why does the gm and american cars lose their a/t more so than the japanese cars. We were cursing on I-5 at 70 MPH in cruise control south of stockton, ca, when the car gave a slight lurch, a thud and slowed down. I stopped checked the tires, all ok. Checked the engine oil and a/t fluid, all ok. Proceeded to oxnard, ca had the a/t repaired costing us seniors $3,600--ouch. The shop said the planetary gear and the clutch disks were broken with metal fragment is the pan. I know it was out of warranty, but gosh, it should have lasted longer than it did konking out at 40,300. Our son drove his toyota camry 130,00 with out problems, why can't american cars be as reliable. My next car will be japanese, and that is a promise. Thanks, lloyd pearson.

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.

While on the interstate I had my cruise control set on 70 MPH and all of a sudden my car jumped to 90 MPH before I realized it. I hit the brakes to disengage it. It did this 3 or 4 times and the last time I nearly rear ended a car so I just quit using it. Also when I would use my signal for a right lane change it would kill the cruise and I would have to hit the gas real quick to get in the other lane.
