Open the full vehicle complaint log (all categories)As I was pulling into a parking spot, traveling at a low speed I naturally applied the brakes but the car accelerated instead jumping a concrete curb and hitting a wall. In that moment I realized I had no control of the vehicle. This sudden unintended acceleration was accompanied by a loss of braking. Pressing on the brakes harder did not stop or slow the car. Brake and accelerator failed. The vehicle is available for inspection. Thankfully the car hit a wall, and there was no injury to myself or others. The parking spot is positioned in front of a concrete wall. The problem has not been confirmed by the dealer as of yet. No warning lamps, message or other signs of malfunction were evident.
ON APRIL 25, 2019 I WAS DRIVING ON A CITY STREET AND THE AUDI PRE SENSE UNEXPECTEDLY ACTIVATED QUITE VIOLENTLY FOR ABOUT 2 SECONDS AND THEN TURNED OFF. WHILE IT DID NOT STOP THE CAR COMPLETELY IT DID REDUCE MY SPEED SIGNIFICANTLY. AT THE TIME I WAS THE ONLY CAR ON THE ROAD; THAT IS, THERE WERE NO OTHER CARS WITHIN SIGHT OF MINE. THERE WAS NO DAMAGE THAT I CAN SEE TO THE CAR BUT I TRUST YOU CAN UNDERSTAND THAT THIS COULD HAVE BEEN A MUCH WORSE SITUATION IF SOMEONE HAD BEEN FOLLOWING CLOSELY BEHIND ME. I ALSO TRUST YOU UNDERSTAND THAT THIS UNEXPECTED BRAKING IS UNACCEPTABLE. THE AUDI SERVICE ADVISOR TOLD ME HE HAS SEEN THIS PHENOMENON BEFORE BUT AUDI HAS NO EXPLANATION OR SOLUTION TO THE PROBLEM.
