Open the full vehicle complaint log (all categories)ENGINE QUIT ON HIGHWAY AT 65 MPH COASTED OF SHOULDER OF ROAD. WRECKER DROPPED AT DEALER. THEY MIS DIAGNOSED A BAD COIL. APPROXIMATELY 6 HOURS LATER THE CAR QUIT IN SAME WAY AGAIN. ANOTHER REPAIR SHOP PROPERLY DIAGNOSED THE PROBLEM AS AN IGNITOR CONTROL MODULE. THE ORIGINAL REPAIR CO.COMMUNITY TOYOTA WILL NOT TAKE RESPONSIBILITY FOR THE UNSAFE CONDITION THEY PUT ME IN. TOYOTA COMPANY SAYS THEY HAVE NO CONTROL OR SAY IN SERVICE PROBLEMS CREATED BY DEALERS. THE FIRST QUESTION THE 2ND REPAIR SERVICE ASK WAS THE CAR RUNNING ROUGH. I SAID NO IT JUST QUIT. THIS QUESTION SHOULD HAVE BEEN ASK BY THE TOYOTA DEALER THAT DID THE FIRST REPAIR. COMMUNITY TOYOTA, BAYTOWN TEXAS. I MADE A GOOD FAITH EFFORT TO GET THE DEALER AND TOYOTA CO. TO ACKNOWLEDGE THEY MADE A MISTAKE AND TAKE CORRECTIVE ACTION SO THEY WILL NOT DO UNSAFE WORK IN THE FUTURE. I BELIEVE IN THE INTEREST OF PUBLIC SAFETY SOME ONE SHOULD SEE THAT THE MECHANIC AND SERVICE MANAGER WERE PROPERLY TRAINED. SO THEY DO NOT MAKE THE SAME MISTAKE IN THE FUTURE AND PUT DRIVERS THEIR PASSENGERS AND OTHER VEHICLES AT RISK. I SENT CERTIFIED LETTERS TO DEALER AND TOYOTA CO. DEALER DID NOT RESPOND TOYOTA CO. SAID THEY DID NOT GET INVOLVED WITH SERVICE COMPLAINTS. PROPERLY TRAINING AND SUPERVISING MECHANICS HAS TO BE SOMEBODY'S RESPONSIBILITY. PLEASE ADVISE ME IF YOU CAN HELP.
