German carmaker Volkswagen has announced a voluntary recall of all gasoline powered Passat models from 1999 through 2005. In particular, some Passat vehicles with an automatic transmission may have an underbody heat shield that could be subject to damage. If the damaged heat shield comes in contact with the vehicle�s exhaust system, it could create a potential safety risk.Additionally, some Passats equipped with 1.8T engines have a fuel line that requires inspection and potential replacement. A small number of vehicles equipped with 4Motion all-wheel-drive will be inspected for potential damage to a fuel tank ventilation valve. According to VW, no accidents or injuries have been recorded. Owner notification is scheduled to begin by May 30, 2008.
