NHTSA Complaint #10986208 — 2012 LEXUS CT

DRIVING UPHILL ON A DIRT ROAD @ ~ 20MPH. GAS ENGINE RUNNING AT THE TIME. FAIRLY STEEP GRADE. ~6% GRADE UPHILL. CAR STARTED TO ACCELERATE AT A RATE I WOULD COMPARE TO MERGING ONTO A HIGHWAY. WAS UNSURE OF WHAT WAS GOING ON AT FIRST SO I DIDN'T ACTUALLY HIT THE BRAKES FOR ABOUT 5 SECONDS AT WHICH POINT I WAS ALREADY AT 45MPH. THE FOUR PASSENGERS IN MY CAR WERE VERY CONFUSED. WE CHECKED THE FLOOR MAT FOR ANY OBSTRUCTIONS AND THAT IT WAS OPERATING CORRECTLY AND IT WAS. I SHUT THE CAR OFF, WAITED A MONTH NITE THEN TURNED IT BACK ON. IMMEDIATELY AS I LET OFF THE BRAKE THE CAR ACCELERATED UP THE HILL. THIS TIME I ONLY ALLOWED IT TO GET UP TO 15MPH BEFORE STOPPING THE VEHICLE. THE BRAKE WAS ACTING AGAINST THE ENGINE PROPELLING THE CAR. BRAKE APPLICATION DID NOT DISENGAGE THE ENGINE FROM TRYING TO MOVE THE CAR FORWARD. I EVEN PUT MY TOES UNDER THE PEDAL TO TRY AND LIFT THE ACCELERATOR MAKING SURE IT WASN'T MECHANICAL ERROR. ZERO MOVEMENT, THE PEDAL WAS IN PLACE. AFTER HAVING LEXUS "ANALYZE" MY VEHICLE THEY CALL ME BACK AND TELL ME "WE CAN'T FIND ANYTHING WRONG WITH IT" AND THAT ALSO THEY DID NOT UPDATE ANY COMPUTERS OR RESET ANYTHING OR SWAP OUT MY BATTERY. THEY EXPECTED ME TO COME PICK UP MY CAR WITHIN THE WEEK OR THEY SAID THEY WOULD REPORT THEIR LOANER CAR STOLEN AND I WOULD BE CHARGED FOR IT. MY ONLY OPTION GIVEN WAS TO GET BACK INTO MY VEHICLE. MY SUSPICION IS MY BATTER ALLOWED ITSELF TO OVERCHARGE WHILE DRIVING DOWN LONG STRETCHES OF MOUNTAIN ROADS AND THEN WAS NOT BEING DRAINED ON THE STRENUOUS UPHILL SECTIONS. THIS OVERCHARGE APPEARED IN THE FORM OF ULTRA ENGINE ASSIST WHICH I EXPERIENCED WITHIN 1 MILE OF STARTING MY CAR AFTER A 4 HOUR HIKE.
