AFFECTED VEHICLES
| Vehicle | Model Year | Assembly Plant | Build Dates |
| F-350/F-450 | 2021 | Kentucky Truck | November 12, 2020 through December 4, 2020 |
REASON FOR THIS SAFETY RECALL
In some of the affected vehicles, it is possible the left-hand inner 5th wheel bracket becomes split during the stamping process. Customers towing a trailer while using a 5th wheel with a cracked lefthand bracket may experience loud knocks/clanks while accelerating and abnormal vibration with no degradation in lateral stability of the truck/trailer combination. If left unrepaired and the vehicle tows a trailer that exceeds 22.8K LBS., the 5th wheel assembly may become loose and may ultimately detach from the vehicle, increasing the risk of a crash.
SERVICE ACTION
Before demonstrating or delivering any new in-stock vehicles involved in this recall, dealers are to inspect and if required, replace the left-hand inner 5th wheel hitch bracket. This service must be performed on all affected vehicles at no charge to the vehicle owner.
OWNER NOTIFICATION AND MAILING SCHEDULE
Owner letters are expected to be mailed the week of June 21, 2021. Dealers should repair any affected vehicles that arrive at their dealerships, whether or not the customer has received a letter.
PLEASE NOTE:
Federal law requires dealers to complete this recall service before a new vehicle is delivered to the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of up to $21,000 per vehicle. Correct all vehicles in your new vehicle inventory before delivery.
SOLD VEHICLES
- Ford has not issued instructions to stop selling/delivering or driving used vehicles under this safety recall. Owners should contact their dealer for an appointment to have their vehicles remedied as soon as practicable. Owners can continue to safely drive their vehicles.
- Immediately contact any of your affected customers whose vehicles are not on your VIN list but are identified in OASIS. Give the customer a copy of the Owner Notification Letter (when available) and schedule a service date.
- Correct other affected vehicles identified in OASIS which are brought to your dealership.
- Dealers are to prioritize repairs of customer vehicles over repairs of new and used vehicle inventory.
STOCK VEHICLES
- Correct all affected units in your new vehicle inventory before delivery.
- Use OASIS to identify any affected vehicles in your used vehicle inventory.
DEALER-OPERATED RENTAL VEHICLES
The Fixing America’s Surface Transportation (FAST) Act law effective June 2016 prohibits a rental company from selling, renting or leasing vehicles subject to a safety or compliance recall. Please consult your legal counsel for legal advice.

TO: All U.S. Ford and Lincoln Dealers
SUBJECT: NEW VEHICLE DEMONSTRATION / DELIVERY HOLD –
Safety Recall 21S23
Certain 2021 Model Year 6.7L F-350/F-450 Vehicles with Dual Rear Wheels
Left Hand Inner 5th Wheel Bracket Inspection
REF: NEW VEHICLE DEMONSTRATION / DELIVERY HOLD – Advance Notice
Safety Recall 21S23
Dated: May 25, 2021
AFFECTED VEHICLES
Vehicle Model Year Assembly Plant Build Dates
F-350/F-450 2021 Kentucky Truck November 12, 2020 through December 4, 2020
Affected vehicles are identified in OASIS and FSA VIN Lists.
REASON FOR THIS SAFETY RECALL
In some of the affected vehicles, it is possible the left-hand inner 5th wheel bracket becomes split
during the stamping process. Customers towing a trailer while using a 5th wheel with a cracked lefthand
bracket may experience loud knocks/clanks while accelerating and abnormal vibration with no
degradation in lateral stability of the truck/trailer combination. If left unrepaired and the vehicle tows a
trailer that exceeds 22.8K LBS., the 5th wheel assembly may become loose and may ultimately
detach from the vehicle, increasing the risk of a crash.
SERVICE ACTION
Before demonstrating or delivering any new in-stock vehicles involved in this recall, dealers are to
inspect and if required, replace the left-hand inner 5th wheel hitch bracket. This service must be
performed on all affected vehicles at no charge to the vehicle owner.
OWNER NOTIFICATION MAILING SCHEDULE
Owner letters are expected to be mailed the week of June 21, 2021. Dealers should repair any
affected vehicles that arrive at their dealerships, whether or not the customer has received a letter.
PLEASE NOTE:
Federal law requires dealers to complete this recall service before a new vehicle is delivered to
the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of
up to $21,000 per vehicle. Correct all vehicles in your new vehicle inventory before delivery.

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.

Director P. O. Box 1904
Service Engineering Operations Dearborn, Michigan 48121
Ford Customer Service Division
May 25, 2021
TO: All U.S. Ford and Lincoln Dealers
SUBJECT: NEW VEHICLE DEMONSTRATION / DELIVERY HOLD – Advance Notice –
Safety Recall 21S23
Certain 2021 Model Year 6.7L F-350/F-450 Vehicles with Dual Rear Wheels
Left Hand Inner 5th Wheel Bracket Inspection
AFFECTED VEHICLES
Vehicle Model Year Assembly Plant Build Dates
F-350/F-450 2021 Kentucky Truck November 12, 2020 through December 4, 2020
Affected vehicles are identified in OASIS and FSA VIN Lists.
REASON FOR THIS SAFETY RECALL
In some of the affected vehicles, it is possible the left-hand inner 5th wheel bracket becomes split during the
stamping process. Customers towing a trailer while using a 5th wheel with a cracked LH bracket may
experience loud knocks/clanks while accelerating and abnormal vibration with no degradation in lateral
stability of the truck/trailer combination. If left unrepaired and the vehicle tows a trailer that exceeds 22.8K
lbs., the 5th wheel assembly may become loose and may ultimately detach from the vehicle, increasing the
risk of a crash.
SERVICE ACTION
DO NOT DEMONSTRATE OR DELIVER any new in-stock vehicles involved in this safety recall. A
complete Dealer Bulletin will be provided to dealers the week of May 31, 2021 when it is anticipated that
parts ordering information and repair instructions will be available to support this safety recall.
IMPORTANT: Dealers should open a Repair Order (RO) only when a full dealer bulletin is published.
Opening a RO against an Awareness or Advance Notice will result in warranty rejections against a
recall.
CUSTOMER NOTIFICATION
Owners of record will be notified via first-class mail after repair instructions and parts ordering information
have been provided to dealers.
PLEASE NOTE:
Federal law requires dealers to complete this recall service before a new vehicle is delivered to the
buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of up to
$21,000 per vehicle. Correct all vehicles in your new vehicle inventory prior to delivery.
QUESTIONS & ASSISTANCE
For questions and assistance, contact the Special Service Support Center (SSSC) via the SSSC Web
Contact Site. The SSSC Web Contact Site can be accessed through the Professional Technician System
(PTS) website using the SSSC link listed at the bottom of the OASIS VIN report screen or listed under the
SSSC tab.
