Defect Involved, Vehicle, Owner, Dealer and Parts Information

General Motors has determined that certain 1984, 1985 and 1986 Chevrolet C31 Light Duty Cab and Chassis models equipped with a low service body and loaded to the maximum required weight for a Federal Motor Vehicle Safety Standard (FMVSS) 301 test failed to comply with the requirements of FMVSS 301 "Fuel System Integrity" during a 30 mph frontal barrier test. The impact caused a hole to be cut into the fuel tank which allowed greater than acceptable fuel spillage. Fuel spillage during and after such a collision could result in a fire.
DEFECT INVOLVED

To correct this noncompliance, it will be necessary to add an additional shield to the front of the original equipment stone shield to protect the fuel tank in the event of a severe frontal impact.

VEHICLES INVOLVED

Involved are certain 1984, 1985 and 1986 Chevrolet C31 Light Duty Cab and Chassis models built within the following VIN breakpoints:
