Vehicle Speed Control, fuel/propulsion System
09/01/2024
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.

FOR ALMOST THE ENTIRE TIME OF 16 YEARS OF OWNING THIS CAR, THE SET CRUISE CONTROL OFTEN TIMES SPEEDS UNCONTROLLABLY. HAVE REPLACED THE MODULE TWICE BUT CONTINUES TO HAPPEN. LOCAL BUICK DEALER TELLS ME THEY HAVE NOT HEARD OF THIS BEFORE. I FIRMLY BELIEVE THEY ARE UNTRUTHFUL.

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.
