1978 Pontiac Bonneville Safety Recalls (2)
THE HUB PORTION OF THE FAN BLADE ASSEMBLY COULD CRACK DUE TO HIGH STRESS LEVELS GENERATED DURING ENGINE OPERATING CONDITIONS. EVENTUALLY, THE BLADE COULD BREAK APART AT THE HUB AND BLADE PIECES COULD BE PROPELLED INTO THE ENGINE. IF THE HOOD IS OPEN WHILE THE ENGINE IS RUNNING, THE FRAGMENTS WOULD BE FREE TO FLY FROM THE VEHICLE.
Remedy: DEALER WILL REPLACE THE FAN BLADE ASSEMBLY WITHOUT CHARGE TO OWNER.
THE REAR WHEEL MOUNTING BOLTS ON THE AFFECTED VEHICLES, ARE BRITTLE AND THEREFORE MAY FRACTURE. THIS BRITTLENESS IS DUE TO IMPROPER HEAT TREATMENT DURING MANUFACTURE. IF THE BOLTS BREAK, THE TIRE AND WHEEL ASSEMBLY MAY SEPARATE FROM THE VEHICLE.
Remedy: DEALER WILL INSPECT AND, IF NECESSARY, WILL REPLACE DEFECTIVE BOLTS ON ALL AXLES AND THE TEN REAR AXLE WHEEL MOUNTING BOLTS, FREE OF CHARGE.
