In the event of a rear end collision, the vehicle sheet metal structure will not perform as designed causing unexpected damage to the fuel tank or fuel lines, resulting in fuel leakage. If this is a fuel leak and an ignition source, a fire could occur.
During assembly of the left rear quarter panel, some welds were missed. This does not comply with the requirements of FMVSS no. 301, "fuel system integrity."
Dealers will inspect for the missing welds and, if necessary, place three whelds between the involved panels applying primer, sealer and anti-corrosion materials.
