Your Vehicle Identification Number (VIN):
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
The Lincoln Motor Company has decided that a defect which relates to motor vehicle safety exists in
your vehicle, with the VIN shown above.
We apologize for this situation and want to assure you that, with your assistance, we will correct this
condition. Our commitment, together with your dealer, is to provide you with the highest level of service
and support.
What is the issue? On your vehicle, the battery cable wire harness may not be properly
secured, allowing contact with the A/C compressor pulley.
What is the risk? Over time, the A/C pulley may rub through the wire harness insulation and
contact the unfused positive battery (B+) circuit, which may result in a short
circuit and potential fire.
What will Lincoln and
your dealer do?
The Lincoln Motor Company has authorized your dealer to install a tie strap
to the battery cable wire harness to prevent future contact with the A/C
compressor pulley. Your dealer will also inspect the battery cable wire
harness for possible damage caused by contact with the A/C pulley and
repair or replace the harness as necessary. These repairs will be free of
charge (parts and labor).
How long will it take? The time needed for this repair is less than one-half day. However, due to
service scheduling requirements, your dealer may need your vehicle for a
longer period of time. Additional time may be required to allow the engine to
cool prior to performing this repair. In addition, your vehicle will/may require
an inspection to determine if parts need to be ordered.
What should you do? Please call your dealer without delay to schedule a service appointment for
Recall 21S34. Provide the dealer with your VIN, which is printed near your
name at the beginning of this letter.
Lincoln has not issued instructions to stop driving your vehicle under this
safety recall. You should contact your dealer for an appointment to have
your vehicle remedied as soon as practicable. You can continue to safely
drive your vehicle.
Lincoln owners of 2017 Model Year or later vehicles affected by this recall
have the option of requesting complimentary Pickup & Delivery service with
a Lincoln vehicle for use during service. Please request Lincoln Pickup &
Delivery through your dealership if you would like to take advantage of this
option.
If you do not already have a servicing dealer, you can access
owner.lincoln.com for dealer addresses, maps, and driving instructions.
The Lincoln Motor Company wants you to have this safety recall completed
on your vehicle. The vehicle owner is responsible for making arrangements

Número de identificación del vehículo (VIN):
Este aviso se le envía de acuerdo con la Ley Nacional de Seguridad y Tránsito de Vehículos de los
EE. UU.
The Lincoln Motor Company ha determinado que existe un defecto relacionado con la seguridad de su
vehículo, con el VIN que aparece más arriba.
Lamentamos esta situación y deseamos asegurarle que, con su ayuda, corregiremos el problema.
Nuestro compromiso, junto con el de su distribuidor, es ofrecerle servicio y apoyo de alto nivel.
¿Cuál es el
problema?
En su vehículo, el arnés de la batería podría no estar correctamente
asegurado, lo cual hace posible el contacto con la polea del compresor del
A/C.
¿Qué riesgo existe? Con el paso del tiempo, la polea del A/C podría rozar en el aislamiento del
arnés y generar contacto con el circuito positivo de la batería (B+) sin
fusible, lo cual podría generar un cortocircuito y un posible incendio.
¿Qué harán Lincoln y
su distribuidor?
The Lincoln Motor Company ha autorizado a su distribuidor a instalar una
cinta de amarre al arnés de la batería a fin de evitar contacto futuro con la
polea del compresor de A/C. Su distribuidor también inspeccionará el arnés
de la batería para detectar posibles daños causados por el contacto con la
polea del A/C y reparar o reemplazar el arnés, según sea necesario. Estas
reparaciones se realizarán sin costo alguno (piezas y mano de obra).
¿Cuánto tiempo
tomará?
El tiempo necesario para reparar será menos de medio día. Sin embargo,
debido a los requisitos de planificación de servicio, es posible que su
distribuidor tarde un poco más. Es posible que se necesite más tiempo para
permitir que el motor se enfríe antes de realizar esta reparación. Además,
es posible que se realice una inspección del vehículo para determinar si se
deben solicitar piezas.
¿Qué debe hacer? Llame a su distribuidor lo antes posible para programar una cita de servicio
para realizar la campaña 21S34. Proporcione el VIN a su distribuidor, el cual
está impreso debajo de sus datos al comienzo de esta carta.
Para esta campaña de seguridad, Lincoln no ha emitido instrucciones de no
manejar el vehículo. Deberá ponerse en contacto con su distribuidor a fin de
programar una cita para solucionar este problema lo más pronto posible.

Affected vehicles are identified in OASIS and FSA VIN Lists.
REASON FOR THIS PROGRAM
In some of the affected vehicles, the rear axle tube may deform and potentially separate at the spring
seat interface. This can potentially cause an axle tube leak, vibration while driving, shuddering upon
acceleration, and drive shaft separation. A separated drive shaft can result in a loss of motive power
while driving and unintended movement when placed in park if parking brake is not applied,
increasing the risk of a crash.
SERVICE ACTION
Before demonstration or delivering any new in – stock vehicles involving this recall, dealers are to
inspect the rear axle for damage
 If no damage is found, both spring seats will need to be reinforced with a weld per technical
instructions.
 If damage is found, axle housing replacement is required. Approximately 1% of affected
vehicles will require axle housing replacement. Vehicle with rear axle damage cannot be safely
driven until the axle housing is replaced.
This service must be performed on all affected vehicles at no charge to the vehicle owner.

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.

Recall Reimbursement Plan for 21S31
Ford and Lincoln dealers are in the best position to quickly and efficiently process reimbursement
requests. However, federal legislation requires all motor vehicle manufacturers to establish
processes through which customers may seek recall reimbursement directly from the manufacturer
or from the dealers.
Regarding the specific reimbursement plan for Recall # 21S31, owners who have paid for service to
remedy the defect or noncompliance must have had that service performed prior to Sept 03, 2021
After this date, if repairs related to this recall are performed by a non-Ford repair facility in an
emergency situation, customers must submit any refund requests through their dealership. As
required by this federal regulation, Ford Motor Company submitted the details of its latest General
Recall Reimbursement Plan in a letter to the National Highway Traffic Safety Administration
(NHTSA) in February 2019. The following is the text of that letter and the Plan:
General Recall Reimbursement Plan
(As submitted to the NHTSA)
Pursuant to the requirements set forth in 49 CFR Part 573 and Part 577 of the Code of Federal
Regulations, Ford Motor Company (Ford) is submitting required information pertaining to our general
reimbursement plan for the cost of remedies paid for by vehicle owners before they are notified of a
related safety recall.
Set forth below is Ford’s general plan to reimburse owners and purchasers for costs incurred for
remedies in advance of notification of potential safely related defects or noncompliance pursuant to
Part 573.6 (c)(8)(i). This plan has not changed since our February 20, 2019 submission.
Reimbursement Notification
Ford’s notice to a vehicle owner in accordance with 49 CFR Part 577 will indicate that Ford is
offering a refund if the owner paid to have service to remedy the defect or noncompliance prior to a
specified ending date. In accordance with Part 573.13 (c)(2), this ending date will be defined as a
minimum of ten calendar days after the date on which Ford mailed the last of its Part 577
notifications to owners, and will be indicated in the specific reimbursement plan available to owners
for an individual recall. This notice will direct owners to seek eligible reimbursement through
authorized dealers or, at their option, directly through Ford at the following address:
Ford Motor Company
P.O. Box 6251
Dearborn, MI 48121-6251
Ford notes that this rule allows for the identification of a beginning date for reimbursement eligibility.
Under the rule, an owner who paid to remedy the defect or noncompliance prior to the identified
beginning date would not be eligible for reimbursement. Ford generally has not established such a
beginning date for reimbursement eligibility and does not presently anticipate changing this general
policy. However, in any case where Ford determines a beginning date is appropriate, Ford will
indicate that date in the owner notice. As permitted by 577.11(e), Ford may not include a
reimbursement notification when all vehicles are well within the warranty period, subject to approval
by the agency.
Version 04-23-19
Costs to be Reimbursed
For vehicles, reimbursement will not be less than the lesser of:
• The amount paid by the owner for the remedy that specifically addressed and was reasonably
necessary to correct the defect or noncompliance that is the subject of the recall, or
• The cost of parts for the remedy (to be no more than the manufacturer’s list retail price for
authorized part(s), plus associated labor at local labor rates, miscellaneous fees (such as
disposal of waste) and taxes.
For replacement equipment, reimbursement will be the amount paid by the owner for the
replacement item (limited by the amount of the retail list price of the defective or noncompliant item
that was replaced, plus taxes, where the brand or model purchased by the owner was different than
the brand or model that was the subject of the recall). If the item of motor vehicle equipment was
repaired, the reimbursement provisions identified above for vehicles will apply.
Ford notes that costs incurred by the owner within the period during which Ford’s original or
extended warranty would have provided for a free repair of the problem will not be eligible for
reimbursement, as provided by Part 573.13 (d)(1).
Entities Authorized to Provide Reimbursement
Ford will continue to use authorized dealers to reimburse owners under the specific reimbursement
plans for a particular recall and will encourage owners to pursue requests for reimbursement directly
through dealers to expedite reimbursement. Ford will also provide a mailing address to which
customers can, at their option, send requests for reimbursement directly to Ford, as previously
noted. Requests for reimbursement sent directly to Ford may take up to 60 days to process.
Whether the owner chooses to pursue reimbursement requests through a dealer or directly through
Ford, the owner will be directed to submit the required documentation, upon which reimbursement
eligibility will be determined.
Required Documentation
The reimbursement determination will depend upon the information provided by the customer.
Consistent with Part 573.13 (d)(4) the following information must be submitted:
• Claimant name and address
• Vehicle make, model, and model year
• Vehicle identification number (VIN) and, for replacement equipment, a description of such
equipment or, for tires, the model, size and TIN (DOT code)
• Identification of the recall number (either the Ford recall number or the NHTSA recall number)
• Identification of the owner of the recalled vehicle at the time that the pre-notification remedy
was obtained
• An original receipt for the pre-notification remedy that includes a breakdown of the amount for
parts, labor, other costs and taxes, including costs for the replacement item. Where the receipt
covers work other than to address the recall or noncompliance, Ford may require the claimant
to separately identify costs that are eligible for reimbursement.
• If the remedy was obtained during the warranty period, documentation indicating that the
warranty was not honored, or the warranty repair did not correct the problem related to the
recall.
Failure to submit all of the above information may result in denial of the reimbursement request.
Version 04-23-19
Additional Information
The Part 577 required owner notice will provide a toll-free telephone number through which specific
information about the reimbursement plan can be requested from Ford. This general reimbursement
plan will be incorporated into notifications pursuant to Part 573.6 by reference. Information specific
to an individual recall also may be incorporated into the Part 573.6 notification.
