CAMPAIGN:INCORRECT LEVEL INDICATION. Cadillac Eldorado 1993

SUBJECT: INCORRECT FUEL LEVEL INDICATION

MODEL: CERTAIN 1993 ELDORADOS AND SEVILLES

General Motors has determined that certain 1993 model Cadillac Eldorados and Sevilles may have a mispositioned fuel sending unit in the fuel tank. At less than one-quarter tank capacity, this can result in the unit giving an incorrect fuel level reading while the fuel level is actually decreasing. If this occurs, the vehicle may run out of fuel even though the fuel gauge indicates 2 to 3 gallons remaining with 40 to 70 miles of driving range.

DEALER ACTION

To prevent this condition from occurring dealers are to realign the fuel sending unit in the fuel tank and replace the Instrument Panel Cluster (IPC) Prom on all involved vehicles as per the Vehicles Involved and Service procedure sections of this bulletin.
