general problems of the 2001 Buick Century

When I have cruise control on but not in use at that moment the car will engage cruise on its own. It does this at a high rate of acceleration with no rhyme or reason as to why. I have to be quick to get it to stop because of the high rate of speed. I do not use the cruise control anymore on my vehicle because of being unsafe. I have been lucky a couple of times I have not rammed into the vehicle in front of me through no fault of mine except for having cruise control on. No it has not been examined or inspected. The problem has not been confirmed by the dealership or and independent service center. It has been confirmed by various drivers of my car. None of them will use cruise control anymore.

Steering locked while driving on highway. Car would speed up on its own without touching the gas peddle. This occurred as soon as the car was taken out of park.

Turned on speed control while driving on interstate, pressed set button to set the speed. The cruise indicator light came on. The car accelerated on its own. My speed went from 65 mph to 80 mph in a few seconds. I depressed the set button again to decelerate, but when I released the set button, the car immediately accelerated again. I depressed the brake to stop the acceleration & turned the speed control switch to the off position.

While driving with the speed control turned on but not engaged the speed control will engage and the engine will race until brake is tapped or speed control switch turned off. This can happened randomly , when resume is engaged , or when lane change signaling.

When putting vehicle into reverse on a deep incline it surged forward, dealer has inspected vehicle, and could not duplicate the problem, manufacturer will be notified.
