NHTSA Complaint #11065308 — 2013 TESLA MODEL S

DRIVER STOPPED CAR WHILE PULLING INTO GARAGE WITH REAR WHEELS ON DRIVEWAY SLOPING DOWN AND AWAY FROM GARAGE AND FRONT WHEELS JUST INSIDE GARAGE. VEHICLE CREEP MODE IN OFF POSITION. CAR AT REST. BRAKE RELEASED, AND VEHICLE BEGAN ROLLING BACKWARD DUE TO GRAVITY. ACCELERATOR APPLIED, AND NO INITIAL RESPONSE, CAR CONTINUED TO ACCELERATE BACKWARD ROLL SPEED, SO PEDAL DEPRESSED FURTHER (TESLA VEHICLE LOGS SHOW 25-50% PEDAL TRAVEL AT THIS POINT), AT WHICH TIME DRIVE UNIT QUICKLY ENGAGED AT 25-50% OF FULL ACCELERATION RESULTING IN A SUDDEN UNINTENTIONAL FORWARD ACCELERATION. DRIVER CAUGHT BY SURPRISE AND ATTEMPTED BRAKING. UNFORTUNATELY, VEHICLE IMPACTED FREEZER UNIT IN GARAGE DESTROYING THE FREEZER AND CAUSING SIGNIFICANT VEHICLE STRUCTURAL DAMAGE. THIS SET OF OPERATING PARAMETERS WAS REPRODUCIBLE AND RELIABLY RESULTED IN A SHORT, BUT NOTABLE, DELAY IN PEDAL RESPONSE WHEN ROLLING BACKWARD, RESULTING IN FURTHER PEDAL DEPRESSION, THEN FOLLOWED BY A SUDDEN ACCELERATION FORWARD, WHICH WAS SHORT, BUT, WITH THE POTENTIAL TO BE SIGNIFICANT WHEN COLLISION HAZARDS EXIST NEARBY. THE VEHICLE OPERATING MANUAL CONTAINS NO WARNING REGARDING THIS SITUATION. TESLA WAS MADE AWARE AND WOULD ONLY COMMENT THAT THE VEHICLE DID NOT MALFUNCTION. WHILE THAT MAY BE THE CASE, THE VEHICLE DESIGN SETS UP DRIVERS FOR ACCIDENTS THAT MIGHT RESULT IN INJURY AND PROPERTY DAMAGE WHEN DRIVERS ARE NOT WARNED OF THE VEHICLE'S RESPONSE IN THIS UNIQUE OPERATING CIRCUMSTANCE. AT THE VERY LEAST, IT SEEMS, TESLA SHOULD INCLUDE A WARNING TO DRIVERS ABOUT THIS SITUATION SO THAT DRIVERS MIGHT BE READY FOR SUDDEN ACCELERATIONS IN SUCH INSTANCES, OR DRIVERS MIGHT SIMPLY SELECT CREEP MODE ON IN SUCH SITUATIONS, WHICH WOULD PREVENT THE SUDDEN ACCELERATION.
