Defect Involved

General Motors has determined that a defect which relates to motor vehicle safety exists in 1985-88 Pontiac Fiero Model vehicles with 2.8L V6 engines (RPO L44).

An interaction of the engine compartment environment in 1985-86 Pontiac Fiero's and maintenance or service related factors results in the potential for engine compartment fires.

If combustible materials come in contact with the exhaust manifold, an engine compartment fire can result. Engine compartment fires can spread to the passenger compartment and cause injury to occupants.
To greatly reduce the possibility of this condition occurring, all vehicles will have changes made in their underhood environment. Specifically, all vehicles will have a manifold deflector installed, a minor change to decklid sealing, a PCV system modification and a general inspection (and repair as necessary) of underhood fluid and wiring systems. Additionally 1985-86 model year vehicles will have a new exhaust manifold installed to bring them up to 1987-88 specifications.
