Open the full vehicle complaint log (all categories)2003 LEXUS SC430. CONSUMER WRITES IN REGARDS TO VEHICLE SUDDEN ACCELERATION. *SMD THE CONSUMER STATED AS SHE PROCEEDED TO PULL OUT OF A PARKING SPACE, SHE THEN PLACE THE VEHICLE IN DRIVE, IT THEN ACCELERATED AT A HIGH SPEED. FINALLY AFTER HITTING A POLE, IT JUMPED THE CURB AND ENDED ON A BUSY STREET. THE DEALERSHIP SENT SOMEONE OUT TO EXPECT THE VEHICLE. THE CONSUMER WAS PROVIDED A DISC THAT SHOWED THE VEHICLE ACCELERATED AT A HIGH SPEED, BUT THEY WOULD NOT SAY THE TRUE CAUSE OF THE PROBLEM, WHICH MAY HAVE HAD SOMETHING TO DO WITH THE WHEEL LOCKING AND THE BRAKES NOT FUNCTIONING.
