Open the full vehicle complaint log (all categories)WHILE DEIVING A MESSAGE ON THE DASH STATED TO STOP WHILE IT IS SAFE. THE CAR PROCEDED TO STALL. IT COULD NOT BE STARTED. I HAPPEN TO BE IN THE MIDDLE OF THE ROAD AND REQUIRED TO CALL FOR HELP TO PUSH THE VEHICLE TO THE SIDE. I WAS ABLE TO START THE CAR LATER THAT DAY TO DRIVE IT HOME. THIS IS THE FORTH TIME IT HAPPENED OVER AN 18 MONTH PERIOD. I WAS VERY LUCKY THAT I WAS NOT IN HEAVY TRAFFIC OR ON A HIGH SPEED ROAD DURING ANY OF THESE EVENTS. I DID HAVE THE CAR TO A REPAIR SHOP AFTER THE LAST TIME IT HAPPENED AND DESCRIBED THE PROBLEM TO THE MCHANIC. REPAIRS WERE MADE BUT NOTHING TO DO WITH THIS PROBLEM. THIS IS DEFINITELY A SAFETY ISSUE AND IT APPEARS THAT IT HAS BEEN REPORTED MANY TIMES. I DO NOT UNDERSTAND WHY THERE HAS NOT BEEN A RECALL ON THIS ISSUE. I DON'T KNOW WHAT TO DO AT THIS TIME OR WHETHER I SHOULD CONTINUE USING THE VEHICLE.
PUSHED THE GAS PEDAL DOWN AND IT WOULDN'T MOVE. AFTER SEVERAL MINUTES IT FREED UP AND WAS ABLE TO GO DOWN THE ROAD. THEN IT LOCKED UP AGAIN. EVENTUALLY MADE IT HOME, APPROXIMATELY 4 MILES AFTER IT LOCKED UP 5 TIMES. *TR
I HAVE HAD THE FUEL LINE REPLACE AND NOW I HAVE TO HAVE THE THROTTLE BODY REPLACED. THE MECHANIC SAID FOR BOTH PARTS - THEY WERE DEFECTIVE PARTS. I CAN NOT PRESS ON THE GAS TO ACCELERATE. AT TIMES THIS HAPPENS WHILE I AM DRIVING WHICH CAN CAUSE AN ACCIDENT. *TR
MANY TIMES, EITHER AFTER A STOP OR LETTING MY FOOT OFF THE GAS PEDAL AND THEN TRYING TO PUSH THE GAS PEDAL AGAIN, THE PEDAL WOULD NOT MOVE, AND I COULD NO LONGER ACCELARATE AND HAVE BEEN FORCED A FEW TIMES TO PULL OFF TO THE SIDE OF THE ROAD UNTIL I COULD GET IT TO PRESS DOWN. SOMETIMES WAITING FOR 5+ MINUTES FOR IT TO WORK. I HAD SOMEONE LOOK AT IT, IT'S THE THROTTLE BODY. IT GETS BUILD UP IN IT AND CAN'T COMPRESS, SEEMS TO BE WORSE IN THE COOLER WEATHER (VS SUMMER). THIS IS A VERY DANGEROUS, ESPECIALLY WITH TRAFFICE AROUND, AND I HAVE HAD MY KIDS IN THE CAR WHEN ITS HAPPENED AND I GET NERVOUS IT'LL HAPPEN IN A SITUATION THAT I CAN'T PREVENT AN ACCIDENT. I HAVE NEVER HAD A PROBLEM WITH A THROTTLE ON ANY OF MY OTHER CARS, NOR HAVE I KNOWN ANYONE WITH THIS ISSUE. *TR
