Complaint Timeline
Chronological view of owner reports
A BAFFEL INTERNAL TO THE FUEL TANK HAS BROKEN OFF CAUSING A LOUD "CLUNKING" WHEN THE CAR HITS BUMPS. THE FAILURE IS COMMON IN THIS MODEL OF MUSTANGS. I SPOKE WITH A MECHANIC ABOUT THE PROBLEM AND HE SAID THE SAME THING HAPPENED IN HIS 1988 MUSTANG. THE DANGER IS THAT A LOOSE METAL OBJECT IN THE FUEL TANK COULD CAUSE A SPARK WHICH COULD EXPLODE THE TANK.
THE FUEL PUMP HAD A SHORT CIRCUIT THAT BURNED THE WIRE HARNESS/ LINKAGES THROUGH THE ELECTRICAL SYSTEM, AND THE FUEL GAUGE. DEALER HAS NOT BEEN CONTACTED. *AK
THE FUEL PUMP MALFUNCTIONED WHE THE VEHICLE WAS DRIVEN OVER A RAILROAD CROSSING.
WHILE DRIVING THE VEHICLE CAUGHT FIRE, UNKNOWN CAUSE OF FIRE. TT
