“VEHICLE WAS IN MOTION ON A CITY STREET GOING STRAIGHT SLIGHTLY DOWNHILL AND THEN UPHILL. THE WEATHER WAS CLEAR. SPEED WAS ABOUT 15-25 MPH. I WAS BRAKING TO SLOW THE CAR DOWN BUT THE CAR ACCELERATED ON ITS OWN ( TOYOTA CALLS IT "UNINTENDED ACCELERATION"). THE CAR CONTINUED ACCELERATING EVEN THOUGH I WAS PRESSING THE BRAKES AS HARD AS I COULD AND IT WAS NOW GOING UPHILL.. TO AVOID CRASHING I PUT THE CAR IN NEUTRAL, AND ENGAGED THE EMERGENCY BRAKE AND HAZARDS. THE ENGINE RACED IN NEUTRAL AND THEN STOPPED RACING.. TOYOTA STARTED A CASE FILE AND INSPECTED IT. THEY SAID EVERYTHING IS WORKING PROPERLY NOW, CASE CLOSED AND I CAN COME GET THE CAR. I HAD IT TOWED THERE AND AM AFRAID TO DRIVE IT UNTIL SOMETHING IS FIXED. IT WAS A TERRIFYING EXPERIENCE. I AM CONCERNED IT COULD HAPPEN AGAIN OR TO OTHER CARS. I AM THOROUGHLY DISAPPOINTED IN TOYOTA'S NONCHALANT ATTITUDE; IT WAS-IS A POTENTIALLY FATAL SITUATION, AND IT SEEMS THAT ACCORDING TO TOYOTA IF SUCH AN ACCIDENT WAS INVESTIGATED NOTHING WOULD SHOW UP.”

“BOUGHT THIS VEHICLE IN 2002. A YEAR LATER NOTICED THAT THE IDLE CONTROLLER HAD PROBLEM. WHEN STARTED THE ENGINE IN THE MORNING, THE IDLE WENT DOWN VERY LOW AND THE ENGINE SHUT DOWN AUTOMATICALLY. AT FIRST IT HAPPENED NOT FREQUENTLY. PAST TWO YEARS I TOOK TO A DEALER FOR MAYOR TUNEUP, THE SYMPTOM STILL RESISTED. TOLD THE DEALER AND THERE WAS NO ACTIONS AT ALL. NOW IT HAPPENS MORE FREQUENTLY. USUALLY IF IT HAPPENS, STEP ON THE GAS PEDDLE ( OVER 2K RPM) FOR A FEW SECONDS. SOMETIMES THE IDLE RETURNS TO NORMAL; BUT MOST OF THE TIMES, THE IDLE SETS VERY LOW. I THINK THE IDLE CONTROL FOR THIS MODEL SHOULD BE RECALLED. *TR”
