A FEW DAYS AGO I HAD AN ACCIDENT. I MADE A LEFT TURN ONTO THE EXPRESSWAY RAMP AT 42 MPH. THE ROAD WAS WET AND AUDI IN THE MIDDLE OF THE TURN ACTIVATED “PRECRASH SENSORS” AND BEGAN TO BRAKE HARD AND THE SYSTEM LOCKED THE STEERING WHEEL. THE CAR WAS COMPLETELY UNCONTROLLABLE AND CRASHED THE FRONT WHEEL INTO THE HIGH CURB, WHICH DAMAGED THE WHEELS, RIM AND AXLES. THE AUDI EXCHANGE DEALERSHIP IN IL CHECKED AND THE SENSORS ARE FUNCTIONING PROPERLY. THEY CLAIMED THAT I IMAGINE THINGS THAT DO NOT EXIST AS THEY SAID IT WAS IMPOSSIBLE FOR THE CAR TO TAKE CONTROL AND TO BRAKE THE CAR. THEY ALSO SAID I DO NOT HAVE THESES FEATURE ON THE CAR, BUT THE CAR IS SO EQUIPPED WITH THIS TECHNOLOGY. ( BECAUSE MANY TIMES IT HAPPENED TO ME OUT OF THE CAR STARTED TO BRAKE WITHOUT A REASON TO BRAKE, WHEN I TRIED TO GO AROUND BIKERS AT THE SAFE DISTANCE, OR WHEN PARKING. WHEN I MADE THE COMPLAINT IN THE AUDI DEALER THEY TOLD ME THAT THIS IS NOT POSSIBLE, AND LAUGHED IN JUNE). I AM AWARE THAT I WAS MOVING FAST BUT FROM MY EXPERIENCE I KNOW THAT I COULD DO THIS TURN WITHOUT AN ACCIDENT. PREVIOUSLY I OWNED A 2013 BMW 528 XDRIVE AND THE CAR SEVERAL TIMES SLIP ON THE SNOW AND I COULD CONTROL THE CAR STILL. I BELIEVE THE PRESENSE SENSORS ACTIVATES THE COLLISION AVOIDANCE SYSTEM RESULTING IN A LOSS OF CONTROL IN THE CAR AND SUBSEQUENT ACCIDENT.
