What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1984 Pontiac Fiero, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
TL* THE CONTACT OWNS A 1984 PONTIAC FIERO (N/A). THE CONTACT STATED THAT THE HEAD BOLT WOULD BECOME SEPARATED FROM THE ENGINE WHENEVER THE VEHICLE WAS STARTED. THE FAILURE CAUSED OIL TO LEAK ONTO THE MANIFOLD AND ENGINE BLOCK. IN ADDITION, THE OIL WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 51,000.
A FRIEND WAS DRIVING MY 1984 PONTIAC FIERO WHEN THE ENGINE SUDDENLY CAUGHT FIRE. AFTER AN INVESTIGATION BY THE LOCAL FIRE DEPARTMENT, THEY DETERMINED AN OIL LIKE SUBSTANCE WAS SPRAYED ON THE MANIFOLD. MY FRIEND WAS ARRESTED FOR ARSON & I WAS ARRESTED FOR CRIMINAL SOLICITATION. AFTER GOING THROUGH THE COURT PROCEDURES AND BEING CONVICTED OF A FELONY I RECEIVED A RECALL LETTER FROM PONTIAC RECALLING MY CAR FOR POSSIBLE ENGINE FIRE. THE CAR WAS ALREADY GONE THOUGH & I NEVER RECEIVED ANY COMPENSATION AND HAVE HAD A FELONY RECORD FOLLOWING ME FOR ALL OF THESE YEARS! I WANT SOMETHING DONE TO HELP IN THIS SITUATION. *TR
