2012 Lexus Ct

First noticed excessive oil usage. Then, engine rumble. Temperature warning light. Took to repair shop who was unable to repair stating ONLY Lexus has tools required to repair. Lexus will not divulge how to repair. Lexus states a letter was mailed to me (never received) in 2016 for a service issue - warranty enhancement. Thus, they are aware of the issue. Now that I’m having issues with the car (2021), the car is too old and has too many miles, thus, Lexus will not repair free of charge under service issue. I am Scared to drive because of hundreds of on line reports that state car can and make completely stop while driving. Toyota is fully aware of the issue and should be help liable to repair under a recall. Note: I’ve had my car repaired for other issues by Certified Lexus since 2016 and the service centers never mentioned the issue/warranty enhancement - a known issue apparently since 2016.

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.
