PROGRAM TERMS
This program will be in effect through February 28, 2026. There is no mileage limit for this program.
URGENCY / EXPIRATION DATE
This Harvest Program has an expiration date of February 28, 2026 to encourage dealers and
customers to have this service performed as soon as possible. Customers will be notified in 2 phases,
with the total number of both phases not to exceed 500.
We recommend dealers utilize their FSA VIN Lists’ names and address to contact customers with
affected vehicles. This will help minimize the number of vehicles that may experience engine damage,
which requires a more extensive repair. FSA VIN Lists are expected to be available on August 28,
2025.

U.S. population of affected vehicles: 502,543, however, no more than 500 vehicles will be selected for
this harvest program. Affected vehicles are identified in OASIS and FSA VIN Lists.
REASON FOR THIS PROGRAM
Ford Product Development (PD) is conducting a harvest program among selected vehicles to
examine spark plugs on engines with high levels of pre-ignition. Using connected vehicle data, PD will
select up to 500 vehicles exhibiting this condition. The customers will be contacted via an owner letter
and requested to visit their dealer for a spark plug replacement. They may, or may not, have a
Malfunction Indicator Lamp (MIL) and may not exhibit any outward misfire or drivability concerns.

Replacing the specified spark plug may prevent future Diagnostic Trouble Codes (DTCs) and possible
engine damage.
SERVICE ACTION
Dealers are to refer to the VIN list supplied with the bulletin and replace the spark plug for the
specified cylinder. This service must be performed on all affected vehicles at no charge to the vehicle
owner. Spark plug replacement closes this FSA. If the vehicle displays a MIL after spark plug
replacement, refer to the appropriate section of the workshop manual. Spark plugs will be called back
for engineering analysis.
To assist vehicle owners to have this repair completed, dealers should:
• Arrange for a mobile repair at the owner’s location, or:
• Arrange to pick up the owner’s vehicle and drive it to the dealership for repairs
o Re-deliver the owner’s vehicle after repairs have been completed.
• Pick-Up & Delivery and mobile service should be made available for all customers. Refer to
the Rental and Claiming sections for further details.
OWNER NOTIFICATION MAILING SCHEDULE
Owner letters are expected to be mailed the week of September 2, 2025 or sooner. Dealers should
repair any affected vehicles that are on the attached VIN list that arrive at their dealerships, whether
or not the customer has received a letter.

REPLACED FSA PARTS INSPECTION AND SIGN OFF
Effective March 1st, 2021, all parts replaced as part of an FSA repair with a repair order open date of
March 1st, 2021, or later must be inspected and signed off on the repair order by a member of your
dealer’s fixed operations management team or an employee the task has been delegated to. If the
task is to be delegated to a non-management employee, the employee needs to be someone other
than the technician who completed the repair and needs to understand the importance of completing
this task consistently and accurately.
• All parts replaced as part of an FSA repair should be returned to the parts department
following the Warranty Parts Retention and Return Policies.
• Inspect the replaced parts to verify the FSA repair was completed.
• If the FSA repair is found to be complete, the designated employee signs the repair order line
or parts return stamp area (electronic or hand signed) for the FSA repair indicating the parts
were inspected and validated to have been replaced.
• After the parts have been inspected, they should be handled based on the guidance in the
parts status report in the Online Warranty System (Hold, Return, CORE, Scrap, etc.). Please
visit FMCDEALER > PARTS & SERVICE > WARRANTY ADMINISTRATION & WARRANTY
PARTS RETURN for the latest Immediate Scrap List information.
• This process is subject to review during warranty audits for FSA repairs with a repair order
open date of March 1st, 2021, or later. Any eligible FSA claims requiring parts replacement
