NHTSA Complaint #11257724 — 2017 TOYOTA SIENNA

HISTORY: PERIODICALLY OVER THE LIFE OF THE VEHICLE, WHEN I PUSH DOWN ON THE GAS PEDDLE THE CAR IS UNRESPONSIVE OR RESPONDS IN FITS AND STARTS. THIS IS USUALLY UPON STARTUP AFTER STOPPING AT A STOP SIGN OR LIGHT. BUT IT DID HAPPEN IN MAY OF 2019 AT 65MPH ON THE FREEWAY (GOING STRAIGHT), RESULTING IN SUDDEN DECELERATION. AS I MOVED OVER LANES TO GET TO THE SIDE OF THE ROAD, THERE WAS A SUDDEN JOLT AND THE CAR BEGAN FUNCTIONING NORMALLY. ON SUNDAY 9/22/19 AT 10AM I LEFT MY HOME WITH MY DAUGHTER TO GO TO THE MOVIES. LESS THAN 5 MINUTES FROM OUR HOME, IN OUR FLAT NEIGHBORHOOD GOING 25MPH, I STOPPED AT THE STOP SIGN THEN ATTEMPTED TO ACCELERATE THROUGH THE INTERSECTION. THE CAR WENT A FEW FEET INTO THE INTERSECTION AND THEN WOULDN'T MOVE, THE ENGINE MAKING A WHIRRING SOUND. IT WAS IN DRIVE. I TURNED ON THE HAZARD LIGHTS AND GENTLY ATTEMPTED TO PUSH THE GAS PEDDLE, FINALLY ABLE TO MOVE THROUGH THE INTERSECTION IN FITS AND STARTS (JOLTING) TO GET TO THE SIDE OF THE ROAD. I PUT THE CAR IN PARK, THEN NEUTRAL. PUSHED DOWN THE GAS IN NEUTRAL AND HEARD THE WHIRRING NOISE. IN DRIVE AND REVERSE, THE JOLTING CONTINUED. I WAS ABLE TO JOLT MY WAY HOME UNDER 10MPH. THE CAR WAS FINE WHEN IT WAS COASTING WITHOUT NEEDING POWER, JOLTING WHEN IT NEEDED POWER. BECAUSE THE CAR IS DANGEROUS, I HAD IT TOWED TO MAGNUSSEN'S TOYOTA, WHERE IT IS AS OF THIS WRITING. THIS IS A VERY DANGEROUS DEFECT AND NEEDS TO BE ADDRESSED AS IT SUDDEN DECELERATION IN AN INTERSECTION OR ON THE FREEWAY MAY RESULT IN DEATH. UPON INITIAL DRIVING, I WAS TOLD THE VEHICLE WAS OPERATING NORMAL. I AM WORRIED THEY WON'T FIX IT AND I WILL END UP WITH A VERY DANGEROUS ALMOST NEW CAR. PLEASE HELP, AND HELP FOR THE SAFETY OF OTHERS WITH THIS SAME DEFECT.
