SUBJECT:

Customer Satisfaction Program 21N10
Certain 2015 – 2021 Model Year Mustang Convertible Vehicles
Door Opens to Secondary Latch Position

PROGRAM TERMS
This program provides a no-cost, one-time repair (if needed) to the door latches for 10 years of
service or 150,000 miles from the warranty start date of the vehicle, whichever occurs first.
This is a one-time repair program.
If a vehicle has already exceeded either the time or mileage limits, this no-cost, one-time repair will
last through September 30, 2023.
Customer satisfaction program eligibility is automatically transferred to subsequent owners.
VEHICLES COVERED BY THIS PROGRAM
Vehicle
Model Year
Assembly Plant
Mustang

2015-2021

Flat Rock

Build Dates
May 12, 2014 through August 11, 2021

Affected vehicles are identified in OASIS.
REASON FOR PROVIDING A NO-COST, ONE-TIME REPAIR
In some of the affected vehicles, a front door latch may open to the secondary latched position while
driving. While the door is in the secondary latched position the driver will notice wind noise from the
door and a door ajar warning will appear on the instrument cluster. This concern does not result in a
fully opened door while driving. The occupant can open the door normally using the door handle.
SERVICE ACTION
If a customer brings a vehicle in for service claiming that the vehicle exhibited this condition, dealers
are to replace both door latches. This service must be performed at no charge to the vehicle owner.
OWNER NOTIFICATION MAILING SCHEDULE
Owner Letters are expected to be mailed in 3rd Quarter 2022 when parts are available in greater
quantities. Dealers should repair any affected vehicles that experience a door opening to the
secondary position, 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
dealers 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.).

•

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,
found not to have been inspected and signed off during a warranty audit will be subject to
chargeback and consideration for enrollment into the Dealer Incomplete Recall Repair
Process.
Note: Other approvals (electronic or handwritten) for add-on repair lines, dealer owned vehicle
repairs, and repeat repairs do not qualify as FSA parts inspection approvals. The post repair FSA
parts inspection process (electronic or handwritten) is independent from other warranty approval
requirements. The approval by the designated employee implies that the FSA parts were found to be
replaced and must be able to be clearly identified on the Repair Order. If multiple FSA’s require
approval on a single Repair Order, each applicable occurrence will require individual post repair
approval by the designated employee.
