NHTSA Complaint #10690117 — 2003 LEXUS ES300

MY CAR OVER THE LAST COUPLE OF YEARS STARTED EXPERIENCING ABNORMAL ACCELERATION . THERE WERE TIMES IT USES TO SURGE OR SOUND LIKE IT WAS RAMPING UP TO GO FAST, EVEN WITH MY FOOT ON THE BREAK, YOU COULD HEAR THE ACCELERATION TRYING TO RAMP UP LIKE IF MY FOOT WASN'T ON THE BREAK IT WOULD JUST TAKE OFF. THEN THE OPPOSITE STARTED TO HAPPEN. MY CAR IDLE WOULD JUST DROP AND BASICALLY WHEN I WOULD GO TO TAKE OFF FROM A STOP, THE CAR WOULD NOT ACCELERATE AT ALL. IT WAS INCONSISTENT SO SOMETIMES IT WOULD OVER ACCELERATE AND SOMETIMES UNDER. THERE WAS NO ACCIDENT, BUT I'VE HAD A FEW CLOSE CALLS AND SOME PEOPLE TO GET AGGRAVATED AT MY CAR.I TOOK IT TO THE PEP BOYS THEY THOUGHT IT NEEDED FLUSHED MAYBE INJECTION CLEANING LIKE ALL OTHER SCENARIOS I AM JUST NOW READING ABOUT. AFTER THAT, IT SEEMED TO WORK FOR A SHORT WHILE, BUT THEN THE ISSUE START OCCURRING AGAIN.
