VEHICLE ABRUPTLY TURNED TO THE RIGHT KNOCKING MY HANDS OFF THE STEERING WHEEL. VEHICLE WENT UP A CURB AND HIT A RETAINING WALL. NO OBVIOUS REASON WHY THE VEHICLE WOULD TAKE CONTROL OF THE STEERING AND OVER RIDING MY INPUT OR IF IT WAS A MECHANICAL FAILURE OF A BALL JOINT ETC, TOO MUCH DAMAGE UNDERNEATH TO VERIFY IF IT WAS BEFORE THE CRASH OR AFTER THE CRASH. IT WAS RAINING HEAVILY AT THE TIME, NOT SURE IF THAT CAUSED AN ISSUE WITH THE SENSORS OR ELECTRONICS.*DT Consumer stated while driving between 15-20 mph adaptive cruise control and lane keep assist were both not on. Vehicle suddenly turned to the right. Warning lights on the dash did not come on and consumer ended up having a flat tire. Dealer was not notified.
