WHILE PULLING INTO A PARKING SPOT IN A SHOPPING CENTER AND GOING ABOUT 5 MILES PER HOUR, SUDDENLY THE ACCELERATOR WENT TO THE FLOOR AND I CRASHED INTO 2 CARS. LUCKILY, I WAS NOT HURT AND THE DAMAGE TO THE 3 CARS WAS SLIGHT BUMPER DAMAGE. I CALLED THE POLICE AND MADE A REPORT. I BROUGHT IT TO THE GARAGE THE NEXT DAY TO HAVE THE CHECKED AND NO PROBLEMS WERE FOUND. THE NEXT DAY I WENT ON THE INTERNET THE CHECK FOR SIMILAR OCCURRENCES AND FOUND SEVERAL. MY CAR WAS A MERCEDES BENZ ML320 SUV. *TR

THE CRANKSHAFT HARMONIC BALANCER PULLEY OF MY MERCEDES ML 320 GAVE OUT ON ME WHILE I WAS DRIVING. THE BELT STARTED TO BURN. I CALLED THE MERCEDES BENZ DEALER IN HONOLULU, HI AND THE SERVICE MANAGER, DAN TOLD ME THAT THERE WAS NO RECALL ON THE PULLEY TO DATE AND THAT I SHOULD BRING MY ML 320 IN TO GET REPAIRED. DAN STATED THAT THE PULLEY MAY NOT BE THE ONLY PART THAT IS DAMAGED AND THAT THE COST COULD PROBABLY GO UP IN PRICE. I STATED THAT I HAD A MECHANIC LOOKED AT IT AND SAID THAT NOTHING ELSE WAS DAMAGED. DAN INSISTED THAT THERE WERE PROBABLY INTERNAL DAMAGES. AT THAT POINT, I DECIDED TO JUST PURCHASE THE PART AND HAVE MY MECHANIC FIX MY CAR BECAUSE MY MECHANIC LOOKED AT MY CAR THOROUGHY AND I FELT THAT THE MANAGER JUST WANTED TO HAVE ME BRING IN MY CAR IN FOR THE REPAIR(S) WHICH WOULD HAVE PROBABLY COST ME A LOT OF MONEY. *AK
