The problem
CERTAIN VEHICLES MAY NOT CONTAIN THE SPECIFIED BODY MOUNTED HEAT SHIELDS. THIS COULD CAUSE HIGH FLOOR PAN TEMPERATURES WHEN THE ENGINE IS IDLED FOR EXTENDED PERIODS OF TIME. FOULED SPARK PLUGS OR OTHER ENGINE CONDITIONS COULD FURTHER INCREASE EXHAUST TEMPERATURES.
What owners should do
THE DEALER WILL INSTALL THE NECESSARY FRAME MOUNTED HEAT SHIELD, IF MISSING.
