Known issues on the 1985 Firebird. Seat belts are named in 12 of the 16 owner complaints. That echoes the recall list, which holds 4 campaigns. Certain 1985 Firebird cars had belt buckles molded from plastic lacking UV protection, so heat and sunlight could weaken them until they broke and would not latch. A separate campaign on certain 1985 Firebird cars with cast aluminum wheels addressed hubs that could crack, risking wheel separation. Of the complaints, 2 reported a crash, 2 a fire, 2 an injury and 1 a death. Brake, suspension and body specifications and procedures here cover those systems.
