This Service Update will be reopened for all vehicles that have had the repair performed with the incorrect part. A new labor code has also been issued.

This service update includes vehicles in dealer inventory and customer vehicles that return to the dealership for any reason. It will expire at the end of the involved vehicle's New Vehicle Limited Warranty period.
Purpose
