Driving vehicle on interstate with a speed of 75 mph with cruise control activated. The cruise control suddenly accelerated on its own. Pushing the off button for the cruise control would not stop the acceleration as well as pushing on the brake. Had to ride the brake and take the first exit available, upon stopping, the vehicle still wanted to go, put vehicle in neutral and then the engine rpm would race to over 4000 rpm and at that time the car was shut off. Tried to start, started hard but rpm would race to over 4000 rpm in neutral when started. After 5 or 6 restarts and shut downs it finally came out of it this, took about about half an hour of time. Did not use cruise control after that for fear of repeat. This had happened prior to this event with my wife but could not remember how long ago the event took place so did not list the event.
The cruise control does not disengage (turn off) while in motion unless you tap the brakes, which could cause a car crash.
Cruise control switch/controller - cannot disengage cruise control via on/off switch, only by turning off the ignition switch. Tapping the brakes will deactivate the cruise function but will not turn it off. We had a near miss of an accident several times because of this problem. Oem manufacturer refused to repair this situation because vehicle was out of warranty.
While driving and without warning the electrical system failed. On several occasions, the brake lights remained on and/or came on by themselves after the engine was cut off. Defective brake light switch assembly had to be replaced. Cruise control would not deactivate at 76 mph.
Brake light stays on and cruise control won't work, and vehicle will not shift out of park. Dealership is aware of problem.
Consumer was activating cruise control at 70 mph when vehicle accelerated suddendly, reaching speeds of 80 mph. To avoid hitting a vehicle in front, consumer swerved into an enbankment and was hit by an oncoming vehicle. Consumer will be contacting dealer to determine cause. Consumer states cruise had previously been set and no more than 20 minutes later, vehicle increased speed to 80 mph in approximately 5 seconds, the safety belt prevented consumer from hitting the windshield, however did not prevent him from hitting the ceiling with his head, one person was injured in accident.
The cruise control would not stay engaged. Nlm.
