REASON FOR THIS PROGRAM

In some of the affected vehicles, the engine head rear cup plugs may not have been properly installed. An improperly installed cup plug could result in an engine coolant leak which may progress to a Malfunction Indicator Light. If left unchecked, the engine may overheat and enter into a reduced performance state.

 

SERVICE ACTION

Dealers are to check both cylinder heads’ rear cup plugs and apply Loctite 290 thread locker to seal the plugs. This service must be performed on all affected vehicles at no charge to the vehicle owner.

To maximize customer satisfaction, ensure to check OASIS for any other open customer satisfaction program(s) against this VIN, and schedule the customer in for service only after parts are available for all open programs.

 

OWNER NOTIFICATION AND MAILING SCHEDULE

Owner letters are expected to be mailed the week of October 2, 2023. Dealers should repair any affected vehicles that arrive at their dealerships, whether or not the customer has received a letter.
