I was traveling on the expressway at 70 mph and i set the cruise control the vehicle was accelerating up a hill and then continued to accelerate to about 90 mph before i noticed what was really happening. it took a lot of effort to get the vehicle stopped and when i put the vehicle in neutral it kept the throttle open and was revving the engine. when i got the vehicle in park and popped the hood to check throttle cables it finally released and started to idle normal again.(the cruise control system was shut off as soon as i noticed the problem but did not change the way the car was acting.) *js
Tl*the contact owns a 2002 buick regal. the contact stated that the cruise control was set to 70 mph and when the contact depressed to the brake pedal to cancel it, the speed suddenly increased to 90 mph. the contact was able to continue driving and so the contact turned the vehicle off for a few minutes. after restarting, the rpms continued to indicate a high reading. the contact had a family member disconnect the cruise control switch. also, the vehicle had to be taken to a local repair shop to have the brakes repaired as they were worn. the failure mileage was approximately 107,000 and the current mileage was 109,703.
The vehicle would not decelerate. please provide more information.
