ON CERTAIN PASSENGER VEHICLES. IF THE ENGINE FAILS TO START AND THE DRIVER HOLDS THE KEY IN THE "START" POSITION FOR AN EXTENDED PERIOD, HIGH CURRENT FLOWS THROUGH THE IGNITION SWITCH, AND SOMETIMES PRODUCES ENOUGH HEAT TO MELT INTERNAL SWITCH PARTS.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.

I CONTACT GMC ABOUT THE CAR AND THEY SAID , THE CAR ENGULF IN FLAMES HAD NOTHING TO DO WITH THEM. *TR”
“1998 OLDSMOBILE ACHIEVA. I OWN THE ABOVE MENTIONED CAR. I HAVE BEEN HAVING A LOT OF PROBLEMS WITH THE BRAKES, NAMELY THE ABS SYSTEM. THE ABS LIGHT CONTINUALLY COMES ON AND MY ABS MAKES A FUNNY NOISE. THE BRAKES ALSO CLUNK SEVERAL TIMES WHEN THE VEHICLE IS FIRST STARTED. I HAVE TAKEN THIS TO BE REPAIRED AT SUBSTANTIAL COST AND I WAS TOLD THAT IT WAS THE WHEEL SPEED SENSOR THAT WAS NOT WORKING CORRECTLY. WELL, IT WAS REPLACED AND THE PROBLEM STOPPED FOR A FEW DAYS. BUT, HAS JUST STARTED AGAIN AND IT IS THE SAME THING. THE ABS LIGHT COMES ON, THE BRAKES GET SPONGY AND FAIL AT SPEEDS FROM 5 MPH TO 55 MPH. THE NOISE FROM THE ABS STARTED AGAIN AND THE BRAKES ARE CLUNKING AGAIN WHEN THE VEHICLE IS FIRST STARTED. I CAN SEEM TO GET ANYBODY THAT IS ABLE TO DO A PERMANENT FIX. AND I CAN'T GET ANY INFO FROM GM ABOUT THIS. I NOTICED THAT SOMEONE ELSE HAD FILED A COMPLIANT ON THIS SITE ABOUT THE EXACT SAME PROBLEM AND IT WAS FOR THE SAME MODEL AND YEAR AS MY CAR. AND, SINCE IT PRESENTS A CLEAR AND PRESENT DANGER, I FIGURED I WOULD FILE ONE TOO. *JB”
“WHILE DRIVING AT HIGHWAY SPEED THE VEHICLE BEGAN TO KNOCK. THEN , ENGINE LIGHT ILLUMINATED. VEHICLE WAS TOWED TO A MECHANIC, AND MECHANIC DETERMINED THAT ENGINE NEEDED TO BE REPLACED, AND REPLACED SOME PARTS. *AK”
