What NHTSA recorded

Possible consequence

If the damaged air cleaner parts are dislodged from their normal position, these parts could come in contact with the hot exhaust manifold and/or hot exhaust gas recirculation (egr) valve tube resulting in a possible engine compartment fire.

Remedy

Dealers will install a redesigned mixer bonnet and air cleaner housing cover, selective upgrades in various connections related to the air induction system, and if needed, a new air cleaner filter.
