Defect, Vehicles, Dealer and Owner Information

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1984 and 1985 Pontiac Firebird Trans Am models. The wheels have been found to contain excessive porosity in the hub area which could potentially affect structural integrity. This could allow the wheel to separate from the vehicle. Wheel separation could cause a loss of vehicle control which could result in a vehicle crash without prior warning.
