owners.
Lincoln strongly recommends having this repair performed as soon as
possible to prevent the occurrence of an injector failure.

How long will it take?

The time needed for this repair is less than one-half day. However, due to
service scheduling requirements, your retailer may need your vehicle for a
longer period of time. Additional time may be required to allow the engine to
cool before performing this repair.

07-Oct-2023 through 29-Feb-2024

US population of affected vehicles: 6,574. Affected vehicles are identified in OASIS and FSA VIN
Lists.
REASON FOR THIS PROGRAM
In all of the affected vehicles, a high-pressure fuel injector tip may crack or become dislodged from
the injector. A cracked or dislodged injector tip may allow excessive fuel into the engine leading to
poor combustion in that injector’s cylinder, which may result in engine vibration and illumination of the
Malfunction Indicator Lamp (MIL). Continued use of the vehicle could lead to an engine hydro-lock
condition, resulting in a “Stop Safely Now” message displaying in the instrument cluster and the
vehicle transitioning to electric drive mode. Continued driving in electric drive mode will deplete the
high voltage battery, which may result in a loss of motive power.
SERVICE ACTION
Ford recommends that dealers DO NOT DEMONSTRATE OR DELIVER any new in-stock vehicles
involved in this customer satisfaction program. A complete Dealer Bulletin will be provided to dealers
mid-May, 2024, when it is anticipated that parts ordering information and repair instructions will be
available to support this customer satisfaction program. For new vehicle storage guidelines, refer to
EFC13033, Storage Guidelines for New Vehicles.
IMPORTANT: Dealers should open a Repair Order (RO) only when a full dealer bulletin is
published. Opening an RO against an Awareness or Advance Notice will result in warranty
rejections against a program.
CUSTOMER NOTIFICATION
Owners of record will be notified via first-class mail after repair instructions and parts ordering
information have been provided to dealers.

QUESTIONS & ASSISTANCE

Contact Site. The SSSC Web Contact Site can be accessed through the Professional Technician
