The 1990 Pontiac Firebird has 3 recalls, the most serious being fuel return hoses that can crack and separate at their crimped fittings, allowing raw gasoline to spill into the engine compartment where it can ignite. This fuel hose concern affects vehicles equipped with 5.0-litre and 5.7-litre engines, where either or both couplings on the return hose are prone to failure. The remaining recall covers the front seatbelt buckle assemblies, whose plastic components were made without an ultraviolet stabilizer. Over time, sunlight and high interior temperatures can degrade and weaken the plastic to the point where the buckle stops latching correctly, leaving the belt unable to hold an occupant during a hard stop or collision.
