The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Some owners may comment on a rattle from the dash area. This rattle could be caused by the engine cover contacting the front of dash/cowl area. The engine cover is retained at the rear by two "C" style retainers. An engine harness that is not properly seated in its U-channel (shown below) can obstruct the engine cover from going into its "C" retainers. This will push the rear of the engine cover up and contact the front of dash/cowl area (shown below).
