 IMPORTANT
There are circumstances under which vehicles that are not currently registered or have never been
registered in a “salt belt” state may be eligible for this service campaign. These circumstances
include:
Vehicles that were relocated into a “salt belt” area and/or vehicles registered in a “non-salt
belt” state and driven in a “salt belt” area. If it is determined that an owner of a vehicle within
the affected VIN production date range relocates or has operated their vehicle in a “salt belt”
area, the dealer should perform the campaign procedure. The dealer should perform this
procedure at no cost to the customer, and the Warranty Prior Approval (PA) Center must be
