PROGRAM TERMS 

This program will be in effect through February 29, 2024. There is no mileage limit for this program.

 

AFFECTED VEHICLES

Vehicle Model Year Assembly Plant Build Dates
Explorer2023ChicagoJanuary 22, 2023 through January 26, 2023
Bronco2023MichiganJanuary 25, 2023 through January 26, 2023
Ranger2023MichiganJanuary 26, 2023

Affected vehicles are identified in OASIS and FSA VIN Lists.

Note: Some vehicles may be in the process of being repaired at the plant. Monitor OASIS before opening an RO and/or beginning a repair. Parts purchased for an FSA can be returned for credit, if required. See the EXCESS STOCK RETURN details in Attachment II for more information.

 

REASON FOR THIS PROGRAM
In all of the affected vehicles, a damaged fixture used during the engine block machining process may have allowed the dimension of one of the head bolt bore holes to exceed specification, reducing head bolt thread engagement. Reduced head bolt thread engagement may not provide enough head bolt clamping force, leading to compromised head to block joint sealing which can cause misfires, rough idle, and/or smoke out of the tailpipe and may eventually result in engine failure.

 

SERVICE ACTION

Before demonstrating or delivering any new in-stock vehicles involved in this program, dealers are recommended to replace the engine assembly. This service must be performed on all affected vehicles at no charge to the vehicle owner.

 

OWNER NOTIFICATION AND MAILING SCHEDULE

Owner letters are expected to be mailed the week of February 27, 2023. Dealers should repair any affected vehicles that arrive at their dealerships, whether or not the customer has received a letter.

 

SOLD VEHICLES

  • Owners of affected vehicles will be directed to dealers for repairs.
  • Immediately contact any of your affected customers whose vehicles are not on your VIN list but are identified in OASIS. Give the customer a copy of the Owner Notification Letter (when available) and schedule a service date.
  • Correct other affected vehicles identified in OASIS which are brought to your dealership.
  • Dealers are to prioritize repairs of customer vehicles over repairs of new and used vehicle inventory.
