REASON FOR THIS SAFETY RECALL
In some of the affected vehicles, underbody insulators may loosen and contact the aluminum driveshaft, resulting in marking or scoring of the driveshaft. Over time, the aluminum driveshaft may fracture, which can result in loss of motive power while driving, unintended vehicle movement while the vehicle is in park if the parking brake is not applied, and secondary damage to surrounding components. A fractured driveshaft may also contact the ground which may cause loss of control of the vehicle while driving. A fractured driveshaft increases the risk of injury or crash.
SERVICE ACTION
Before demonstrating or delivering any new in-stock vehicles involved in this recall, dealers are to secure both the driver and passenger-side underbody insulators and inspect the driveshaft, fuel vapor lines and electrical connectors for damage and repair as required. This service must be performed on all affected vehicles at no charge to the vehicle owner.

CERTAIN 2021-2022 FORD F-150 VEHICLES EQUIPPED WITH ALUMINUM DRIVESHAFTS– UNDERBODY INSULATORS LOOSE
21S56 Amendment #1 Submission Date: 14-JAN-2022
Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the noncompliance decision.
July – August 2021
On July 1, 2021, Ford’s Critical Concern Review Group (CCRG) initiated an investigation into reports of inadequate underbody insulator adhesion on 2021 MY F-150 vehicles based on warranty claims of insulators coming loose. Two underbody acoustic/thermal insulators are installed on certain Crew Cab F-150 vehicles with the 302A and above option package. Two push pins assist in attachment of each insulator to the cab underbody in addition to pressure sensitive adhesive. Warranty claims at the time described sagging of one or both insulators, in some cases making contact with the U-joint at the transfer case end of the driveshaft on HEV units that was audible to a driver. CCRG’s investigation into potential vehicle effects of loose insulators continued.
September 2021
On September 16, 2021, Driveline Engineering informed CCRG that seven reports of driveshaft damage likely caused by underbody insulator contact on 2021 MY F-150 vehicles had been received, with the earliest dated July 23, 2021. The first four of the seven reports did not attribute driveshaft fracture to insulator contact. Once the CCRG was made aware of reports attributing driveshaft fracture to insulator contact, package and vehicle complexity studies were conducted and found that 4×4 145” wheelbase Crew Cab vehicles are equipped with an aluminum driveshaft that is susceptible to contact from a sagging passenger side insulator.
October – November 2021
Vehicle package and CAD studies continued, including assessment of powertrain variation. Field return parts were also evaluated. A vehicle clinic was conducted to evaluate all potential effects of a loose insulator on a variety of F-150 vehicle configurations, including proximity to other driveline configurations, fuel lines, brake lines, and electrical systems. Subsequent analysis found that the risk of driveline contact exists with a loose or sagging driver or passenger side insulator.
As of December 7, 2021, there have been 27 reports of fractured aluminum driveshafts potentially related to a sagging underbody insulator on these vehicles.
On December 9, 2021, Ford’s Field Review Committee reviewed the concern and approved a field action.
Ford is not aware of any reports of accident or injury related to this condition.

CCRG’s investigation into potential vehicle effects of loose insulators continued. September 2021 On September 16, 2021, Driveline Engineering informed CCRG that seven reports of driveshaft damage likely caused by underbody insulator contact on 2021 MY F-150 vehicles had been received, with the earliest dated July 23, 2021. The first four of the seven reports did not attribute driveshaft fracture to insulator contact. Once the CCRG was made aware of reports attributing driveshaft fracture to insulator contact, package and vehicle complexity studies were conducted and found that 4×4 145” wheelbase Crew Cab vehicles are equipped with an aluminum driveshaft that is susceptible to contact from a sagging passenger side insulator. October – November 2021 Vehicle package and CAD studies continued, including assessment of powertrain variation. Field return parts were also evaluated. A vehicle clinic was conducted to evaluate all potential effects of a loose insulator on a variety of F-150 vehicle configurations, including proximity to other driveline configurations, fuel lines, brake lines, and electrical systems. Subsequent analysis found that the risk of driveline contact exists with a loose or sagging driver or passenger side insulator. As of December 7, 2021, there have been 27 reports of fractured aluminum driveshafts potentially related to a sagging underbody insulator on these vehicles. On December 9, 2021, Ford’s Field Review Committee reviewed the concern and approved a field action. Ford is not aware of any reports of accident or injury related to this condition.

February 2022 Ford Motor Company Ford Customer Service Division P. O. Box 1904 Dearborn, Michigan 48121 1904 * * * IMPORTANT SAFETY RECALL * * * Safety Recall Notice 21S56 / NHTSA Recall 21V986 2021 F-150 Ford Truck Your Vehicle Identification Number (VIN): This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Ford 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, underbody insulators may loosen and contact the aluminum driveshaft, resulting in marking or scoring of the driveshaft. Continued contact may result in driveshaft fracture. What is the risk? A fractured driveshaft poses the risks of loss of motive power while driving, unintended vehicle movement while the vehicle is in park if the parking brake is not applied, and secondary damage to surrounding components. A fractured driveshaft may also contact the ground which may cause loss of control of the vehicle while driving. A fractured driveshaft increases the risk of injury or crash. What will Ford and your dealer do? Ford Motor Company has authorized your dealer to secure the underbody insulators, and inspect the driveshaft, fuel vapor lines and electrical connectors for damage and repair as necessary 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. In addition, your vehicle will require an inspection to determine if parts need to be ordered. What should you do? Please call your dealer without delay and request a service date for Recall 21S56. Provide the dealer with your VIN, which is printed near your name at the beginning of this letter. Ford 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. If you do not already have a servicing dealer, you can access ford.com/support for dealer addresses, maps, and driving instructions. Ford Motor Company wants you to have this safety recall completed on your vehicle. The vehicle owner is responsible for making arrangements to have the work completed. Ford Motor Company can deny coverage for any vehicle damage that may result from the failure to have this recall performed on a timely basis. Therefore, please have this recall performed as soon as possible. Please note: Federal law requires that any vehicle lessor receiving this recall notice must forward a copy of this notice to the lessee within ten days. © Copyright 2022 Ford Motor Company 07510 21S56/DTB121S561 1 of 4 A/1/000001/1 771514328216 A/1/000001/1 JOHN A.

UU. Ford 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, aisladores de la parte inferior de la carrocería podrían aflojarse y tener contacto con la flecha de mando de aluminio, lo que genera marcas o rayados de la flecha de mando. El contacto continuo podría tener como resultado la fractura de la flecha de mando. ¿Qué riesgo existe?

Una flecha de mando fracturada también podría entrar en contacto con la tierra que podría causar la pérdida de control del vehículo mientras maneja. Una flecha de mando fracturada aumenta el riesgo de choque o de sufrir lesiones o choque. ¿Qué medidas adoptarán Ford y su distribuidor? Ford Motor Company ha autorizado a su distribuidor a asegurar los aisladores de la parte inferior de la carrocería y a inspeccionar la flecha de mando, las tuberías de vapor de combustible y los conectores eléctricos en busca de daños y reparar si fuera necesario, 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. Además, se deberá realizar una inspección del vehículo para determinar si se deben solicitar piezas. ¿Qué debe hacer? Llame a su distribuidor lo antes posible y solicite una cita de servicio para llevar a cabo la campaña 21S56. Proporcione el VIN a su distribuidor, el cual está impreso debajo de sus datos al comienzo de esta carta. Para esta campaña de seguridad, Ford 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. Puede continuar manejando su vehículo con seguridad.

REASON FOR THIS SAFETY RECALL In some of the affected vehicles, underbody insulators may loosen and contact the aluminum driveshaft, resulting in marking or scoring of the driveshaft. Over time, the aluminum driveshaft may fracture, which can result in loss of motive power while driving, unintended vehicle movement while the vehicle is in park if the parking brake is not applied, and secondary damage to surrounding components. A fractured driveshaft may also contact the ground which may cause loss of control of the vehicle while driving. A fractured driveshaft increases the risk of injury or crash. SERVICE ACTION Before demonstrating or delivering any new in-stock vehicles involved in this recall, dealers are to secure both the driver and passenger-side underbody insulators and inspect the driveshaft, fuel vapor lines and electrical connectors for damage and repair as required. This service must be performed on all affected vehicles at no charge to the vehicle owner. OWNER NOTIFICATION MAILING SCHEDULE Owner letters were mailed the week of January 31, 2022.

PARTS RETENTION, RETURN, & SCRAPPING Follow the provisions of the Warranty and Policy Manual, Section 1 – WARRANTY PARTS RETENTION AND RETURN POLICIES. If a replaced part receives a scrap disposition, the part must be scrapped in accordance with all applicable local, state and federal environmental protection and hazardous material regulations. Federal law prohibits selling motor vehicle parts or components that are under safety, compliance, or emissions recall. EXCESS STOCK RETURN Excess stock returned for credit must have been purchased from Ford Customer Service Division in accordance with Policy Procedure Bulletin 4000. 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.

These vehicles are not produced in VIN order. Information as to the applicability of this action to specific vehicles can best be obtained by either calling Ford’s toll-free line (1-866-436-7332) or by contacting a local Ford or Lincoln dealer who can obtain specific information regarding the vehicles from the Ford On-line Automotive Service Information System (OASIS) database. Production Dates : JAN 10, 2020 – NOV 20, 2021 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Underbody thermal/acoustic insulators may loosen and contact the aluminum driveshaft, resulting in marking or scoring of the driveshaft. Over time, the aluminum driveshaft may fracture due to heat build-up and/or material thickness reduction that changes the mechanical properties of the aluminum material. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : A fractured driveshaft may result in loss of motive power while driving, unintended vehicle movement while the vehicle is in park if the parking brake is not applied, and may result in secondary damage to surrounding Part 573 Safety Recall Report 21V-986 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 components. A fractured driveshaft may also contact the ground which may cause loss of control of the vehicle while driving. A fractured driveshaft increases the risk of injury or crash. Description of the Cause : Inadequate adhesion of the insulators to the vehicle underbody results in loosening and sagging of the insulators. Identification of Any Warning that can Occur : Operators may observe a loose underbody insulator, or they may hear a rattling, clicking or clunking noise due to a loose underbody insulator contacting the driveshaft. Marking or scoring of the driveshaft may be visible in the area of underbody insulator contact. Involved Components : Component Name 1 : Underbody Insulator – Driver Side Component Description : Underbody Acoustic Insulator – Driver Side Component Part Number : ML3B-1611205-AC Component Name 2 : Underbody Insulator – Driver Side Component Description : Underbody Acoustic Insulator – Driver Side Component Part Number : ML3B-1611205-BA Component Name 3 : Underbody Insulator – Passenger Side Component Description : Underbody Thermal/Acoustic Insulator – Passenger Side Component Part Number : ML3B-1611204-AD Component Name 4 : Underbody Insulator – Passenger Side Component Description : Underbody Thermal/Acoustic Insulator – Passenger Side Component Part Number : ML3B-1611204-BB Supplier Identification : Component Manufacturer Name : Lydall Thermal/Acoustical, Inc.
