After exiting a car wash (automated)on Monday-7/3/23, I was attempting to stop my vehicle so I could dry the exterior with towels. I was on the car wash property and as I approached an area that was open, I attempted to stop the vehicle, the engine revved very high and the vehicle took off at a very high speed in fractions of a second. The vehicle then climbed over a flower embankment and hit the wall of the Car wash. The impact was so great that it put a large hole in the wall and ruptured a main water line creating a huge water leak. The fire department and police officer arrived at the scene to make a report. My initial thought was that my sandal may have got trapped but after returning home and rethinking the entire incident may times I believe this was “UNINTENTIONAL ACCELERATION “ The driver side airbag and knee airbag were deployed. Thankfully I was not hurt. Had this happened when I was on a road or a grocery store/ mall parking lot things could have been very serious. I have insurance through State Farm and have requested them numerous times to have a diagnostic check done to identify the reason for this to happen and they have declined my request. Please let me know what the next steps are.
CAR HAS TWICE ATTEMPTED TO ACCELERATE WHEN NOT GOING VERY FAST AS IF IT WAS ATTEMPTING TO GET BACK TO WHAT THE CRUISE CONTROL WAS SET FOR. CRUISE CONTROL WAS NOT ON AND I HAVE NEVER USED IT SINCE I PURCHASED THE CAR. IT DOES NOT WANT TO STOP ACCELERATING WHEN I TAP THE BRAKE AND HAVE HAD TO BRAKE SEVERAL TIMES TO GET THE ACCELERATING TO STOP. BOTH TIMES I WAS IN TRAFFIC BUT NOT GOING VERY FAST AS I WAS ACCELERATING FROM BEING STOPPED AT LIGHT. THERE WAS NO ACCIDENT AS I WAS ABLE TO GET THE VEHICLE UNDER CONTROL AND EVENTUALLY TO HAVE THE ACCELERATING STOP. I TRIED TO CALL THE CADILLAC CUSTOMER SERVICE NUMBER BUT WAS UNABLE TO GET THROUGH DUE TO THE HOLIDAYS. I INTEND TO TAKE IT TO SERVICE PLACE TOMORROW TO CHECK IF THE THROTTLE MIGHT BE DIRTY OR DEFECTIVE BUT AM WONDERING IF THERE MIGHT BE SOMETHING WRONG WITH THE SOFTWARE CONTROLLING THE FEATURES OF THE CAR.
