Chronology of Defect / Noncompliance Determination
Mid-February 2023, DTNA received a report on an incident involving failed tie rod assembly and
opened a preliminary investigation. Upon returned failed part analysis, it was determined that
the driver’s side tie rod disengaged from the steering arm during low speed maneuvering.
Around late February 2023 through early March 2023, DTNA identified that the subject vehicle
experiencing the failure, was re-worked at a different station due to certain requirements, and
was not manufactured through standard process involving multiple inspection points. In about
mid-March 2023, DTNA identified a population of certain axles, that were manufactured at a
rework station. DTNA opened an official investigation immediately following receiving this
notice of a possible presence of a defect, and on March 29, 2023, out of an abundance of
caution, DTNA decided to initiate a new voluntary safety recall to campaign all the listed
vehicles. As of March 31st 2023, DTNA is aware of 1 field report and 0 warranty claims related
to missing front steer axle tie rod castle nut cotter pin. DTNA is not aware of any accidents or
injuries due to this defect condition. On April 7 2023, DTNA finalized the affected population
after further determining precise vocational application of the vehicles. On May 26, 2023, DTNA
amended the Defect Information Report to clarify and consolidate the model listing (to
facilitate reading comprehension with no change to the population).
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufacture’s plan for
reimbursement.
DTNA is preparing remedy and is currently under development. Repairs will be performed free
of charge by Daimler Truck North America authorized service facilities. Details of the
reimbursement plan will be included in the owner’s notification letter. Owners are directed to
seek reimbursement through authorized deal.

TO: My Communication
SUBJECT: Stop Delivery Order: Safety Recall D23R6 (FL970)
SAFETY RECALL NOTICE On April 03, 2023, Daimler Truck North America (“DTNA”) filed a Defect Information Report (“DIR”) with the National Highway Traffic Safety Administration (“NHTSA”) and a Defect Information Notice (“DIN”) with Transport Canada (“TC”) informing the agencies of our intent to conduct a voluntary safety recall.
It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied. Some of the vehicles subject to this “Stop Delivery Order” may be in your new vehicle inventory. Until further instructions are available, new vehicles subject to this “Stop Delivery Order” must be held and not be delivered to customers.
DTNA strongly recommends that dealers and distributors remedy recalls before selling used vehicles. For any used vehicle with an open recall not remedied before sale, DTNA requires that the dealer or distributor notify prospective buyers of the open recall.

Problem:
On the affected vehicles, the steer axle tie rod castle nut cotter-pin may be missing. This may cause the castle nut to back off, which might allow taper-end to displace from the steering arm. This could lead to a loss of steering response and a lack of direction control, potentially increasing the risk of a crash. Driver may experience some additional free-play in the steering and/or feel an improper steering alignment.
Solution:
DTNA is preparing remedy and is currently under development. Repairs will be performed free of charge by Daimler Truck North America authorized service facilities. Details of the reimbursement plan will be included in the owner’s notification letter. Owners are directed to seek reimbursement through authorized dealer.
Owner Notification Mailing Schedule:
Interim Owner letters were mailed to affected Customers on: 06/02/2023.
Final Owner letters will be mailed to affected Customers on: 08/14/2023

On the affected vehicles, the steer axle tie rod castle nut cotter pin may be missing, allowing the steering arm to detach. This could lead to a loss of steering response and a lack of direction control, potentially increasing the risk of a crash. The driver may experience some additional free-play in the steering and/or feel an improper steering alignment.
A Daimler Truck North America authorized service facility will remove the cotter pin, if present, and inspect the installation of the castle nut. If the installation is correct, then a new cotter pin will be installed. If the installation is incorrect, then the tie rod assembly will be replaced. The recall will take approximately one half to three hours and will be performed free of charge.
Please contact an authorized Daimler Truck North America dealer to arrange to have the recall performed and to ensure that parts are available at the dealership.

Description of the Defect : On the affected vehicles, front steer axle tie rod castle nut cotter pin may be missing from the assembly.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : On the affected vehicles, the steer axle tie rod castle nut cotter-pin may be
missing. This may result in the castle nut backing off and displacement of the taper-end from the steering arm. This may result in a loss of steering response and lack of direction control increasing the risk of crash.
Description of the Cause : Re-worked at a different station due to certain requirements, and was not manufactured through standard process involving multiple inspection points. Identification of Any Warning
that can Occur : Driver may experience some additional free-play in the steering and/or feel an improper steering alignment. Involved Components : Component Name 1 : Front Steer Axle Component Description : Tie rod castle nut cotter-pin

Country : United States Chronology :
Mid-February 2023, DTNA received a report on an incident involving failed tie rod assembly and opened a preliminary investigation. Upon returned failed part analysis, it was determined that the driver’s side tie rod disengaged from the steering arm during low speed maneuvering. Around late February 2023 through early March 2023, DTNA identified that the subject vehicle experiencing the failure, was re-worked at a different station due to certain requirements, and was not manufactured through standard process involving multiple inspection points. In about mid-March 2023, DTNA identified a population of certain axles, that were manufactured at a rework station. DTNA opened an official investigation immediately following receiving this notice of a possible presence of a defect, and on March 29, 2023, out of an abundance of caution, DTNA decided to initiate a new voluntary safety recall to campaign all the listed vehicles. As of March 31st 2023, DTNA is aware of 1 field report and 0 warranty claims related to missing front steer axle tie rod castle nut cotter pin.
DTNA is not aware of any accidents or injuries due to this defect condition. On April 7 2023, DTNA finalized the affected population after further determining precise vocational application of the vehicles. On May 26, 2023, DTNA amended the Defect Information Report to clarify and consolidate the model listing (to facilitate reading comprehension with no change to the population). DTNA developed a final remedy for this issue and on June 23, 2023, DTNA updated the description of the remedy section of its Defect Information Report. Description of Remedy :
Description of Remedy Program : A Daimler Truck North America authorized service facility will remove the
cotter pin, if present, and check the torque of the castle nut. If the torque is found to be correct, then a new cotter pin will be installed, if the torque is found to be incorrect, then a new tie rod assembly will be installed. This repair is expected to take approximately one half to three hours. Details of the reimbursement plan will be included in the owner’s notification letter. Owners are directed to seek reimbursement through authorized dealers. How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production : Presence of required cotter-pin 2/23/2023: 2 Quality Alerts Posted: Red Tag required 100% at first station on production line with NOK (Not Okay) operations, and Rework Alert.

Description of the Defect : On the affected vehicles, front steer axle tie rod castle nut cotter pin may be missing from the assembly.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : The steer axle tie rod castle nut cotter-pin on the affected vehicles may be
missing. This may cause the castle nut to back off, which might allow taper- end to displace from the steering arm. This could lead to a loss of steering response and a lack of direction control, potentially increasing the risk of a crash. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-238 Page 5 Description of the Cause : Re-worked at a different station due to certain requirements, and was not manufactured through standard process involving multiple inspection points. Identification of Any Warning

Country : United States Chronology :
Mid-February 2023, DTNA received a report on an incident involving failed tie rod assembly and opened a preliminary investigation. Upon returned failed part analysis, it was determined that the driver’s side tie rod disengaged from the steering arm during low speed maneuvering. Around late February 2023 through early March 2023, DTNA identified that the subject vehicle experiencing the failure, was re-worked at a different station due to certain requirements, and was not manufactured through standard process involving multiple inspection points. In about mid-March 2023, DTNA identified a population of certain axles, that were manufactured at a rework station. DTNA opened an official investigation immediately following receiving this notice of a possible presence of a defect, and on March 29, 2023, out of an abundance of caution, DTNA decided to initiate a new voluntary safety recall to campaign all the listed vehicles. As of March 31st 2023, DTNA is aware of 1 field report and 0 warranty claims related to missing front steer axle tie rod castle nut cotter pin.
DTNA is not aware of any accidents or injuries due to this defect condition. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-238

Mid-February 2023, DTNA received a report on an incident involving failed tie rod assembly and opened a preliminary investigation. Upon returned failed part analysis, it was determined that the driver’s side tie rod disengaged from the steering arm during low speed maneuvering. Around late February 2023 through early March 2023, DTNA identified that the subject vehicle experiencing the failure, was re-worked at a different station due to certain requirements, and was not manufactured through standard process involving multiple inspection points. In about mid-March 2023, DTNA identified a population of certain axles, that were manufactured at a
rework station. DTNA opened an official investigation immediately following receiving this notice of a possible presence of a defect, and on March 29, 2023, out of an abundance of caution, DTNA decided to initiate a new voluntary safety recall to campaign all the listed vehicles. As of March 31st 2023, DTNA is aware of 1 field report and 0 warranty claims related to missing front steer axle tie rod castle nut cotter pin. DTNA is not aware of any accidents or injuries due to this defect condition. On April 7 2023, DTNA finalized the affected population after further determining precise vocational application of the vehicles.
