What is wrong

On certain vehicles equipped with a 3.8L engine, degradation of the front rocker cover gasket may result in eventual oil seepage. Under hard braking, drops of engine oil may be deposited on the exhaust manifold. If the manifold is hot enough and the oil runs below the heat shield, it may ignite into a small flame and, in some instances, the fire may spread to the plastic spark plug wire channel and beyond. An under-hood fire could result in injury and/or property damage.

What the dealer will do

Dealers will replace the engine’s front valve cover and front-valve-cover gasket with new parts. The engine’s plastic “beauty” cover and plastic oil-fill-tube extension will also be removed, if they haven’t been already. Note: This recall supersedes and is an expansion of recalls 2008-081, 2009-105 and 2015-145. All vehicles having been inspected and/or serviced under the previous recall will require re-inspection and repair.
