Number potentially involved: 16676 Estimated percentage of involve with defect: 1% Defect / Noncompliance Description For this Defect/Noncompliance: Describe the defect or noncompliance: On affected chassis, the tire valve stem extension for the inner wheel may contact the outer wheel rim opening and become damaged. Damage to the valve stem extension may result in a loss of tire pressure of the inner wheel. This is a follow-on recall to 20V529 (DTNA # FL861), improving the remedy. Describe the safety risk: Damage to the tire’s valve stem may lead to loss of air pressure, which, if unnoticed, could lead to a flat tire or on dual-wheels an overloaded tire. In extreme situations, rapid loss of tire pressure could increase the risk of a crash. Identify any warning which can precede or occur: Operators may identify an audible rattling noise from the stem extension rubbing against the wheel opening while driving. Visual inspection during inspection or during maintenance may reveal stabilizer is dislocated, damage to the stem extension, or the rim, and low tire pressure of the inner tire. If applicable, identify the manufacture of the defective or noncompliant component.: N/A Involved Components Wheel/rim outer ACC40620 in combination with inner ACC50487 or ACC51487, Extension Stabilizer 13-10232-000, Stem Extension 13-10026-000, Valve Stem 13-10303-000 or 13-10027-000 Chronology of Defect / Noncompliance Determination Provide the chronology of events leading up to the defect decision or test data for the noncompliance decision: In September of 2021, DTNA received two Vehicle Owner Questionnaires (VOQs) from customers complaining of valve stem(s) continuing to make contact with the outer wheel hand hole after having recall 20V529 (DTNA # FL861) performed. At the time of the original recall, based upon the information available at the time, DTNA reasonably believed its original defect remedy to be adequate. Based upon the more recent information, however, DTNA promptly opened an investigation and began reviewing the information from these VOQs. In late September, DTNA received an additional VOQ with a similar complaint with additional information that caused the scope of the investigation to widen. In October of 2021, DTNA received an additional VOQ and continued investigating. In November of 2021, DTNA reviewed Customer and dealer complaint tickets and discovered possible instances where the previous recall remedy may not have been completely effective. In mid-November, out of an abundance of caution, DTNA decided to conduct a recall to institute a different remedy. In February 2022, DTNA discovered a claim from a dealer who may have reinstalled suspect components from vehicles that were remedied with the recall fix prior to release from the factory. After investigating the issue, it was discovered that the aftermarket parts system did not reflect the correct, remedied condition of the affected vehicles. Out of an abundance of caution, DTNA expanded the population to include units updated prior to shipping from the factory for increased visibility on units updated at the factory, to take steps intended to prevent vehicles from reverting to the pre-remedied state. On February 28, 2022, DTNA received information from the field where certain vehicles included in the recall, do not have the suspect parts. DTNA began investigating this information and discovered that three unique Build of Materials (BOMs) were inadvertently included in the original population of vehicles potentially affected. These three BoMs do not include the suspect parts. On March 2, 2022, DTNA amended the affected population with most current population number. Identify the Remedy Describe the defect/noncompliance remedy program, including the manufacture’s plan for reimbursement. The inner valve stem extension and stabilizer will be removed. Repairs will be performed by Daimler Trucks North America authorized service facilities. Details of the reimbursement plan will be included in the owner’s notification letter.

Production Dates : FEB 22, 2017 – NOV 15, 2021 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : On affected chassis, the tire valve stem extension for the inner wheel may contact the outer wheel rim opening and become damaged. Damage to the valve stem extension may result in a loss of tire pressure of the inner wheel. This is a follow-on recall to 20V529 (DTNA # FL861), improving the remedy. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Damage to the tire’s valve stem may lead to loss of air pressure, which, if unnoticed, could lead to a flat tire or on dual-wheels an overloaded tire. In extreme situations, rapid loss of tire pressure could increase the risk of a crash. Description of the Cause : NR Identification of Any Warning that can Occur : Operators may identify an audible rattling noise from the stem extension rubbing against the wheel opening while driving. Visual inspection during inspection or during maintenance may reveal stabilizer is dislocated, damage to the stem extension, or the rim, and low tire pressure of the inner tire.

At the time of the original recall, based upon the information available at the time, DTNA reasonably believed its original defect remedy to be adequate. Based upon the more recent information, however, DTNA promptly opened an investigation and began reviewing the information from these VOQs. In late September, DTNA received an additional VOQ with a similar complaint with additional information that caused the scope of the investigation to widen. In October of 2021, DTNA received an additional VOQ and continued investigating. In November of 2021, DTNA reviewed Part 573 Safety Recall Report 21V-921 Page 6 The information contained in this report was submitted pursuant to 49 CFR §573 Customer and dealer complaint tickets and discovered possible instances where the previous recall remedy may not have been completely effective. In mid-November, out of an abundance of caution, DTNA decided to conduct a recall to institute a different remedy. In February 2022, DTNA discovered a claim from a dealer who may have reinstalled suspect components from vehicles that were remedied with the recall fix prior to release from the factory. After investigating the issue, it was discovered that the aftermarket parts system did not reflect the correct, remedied condition of the affected vehicles. Out of an abundance of caution, DTNA expanded the population to include units updated prior to shipping from the factory for increased visibility on units updated at the factory, to take steps intended to prevent vehicles from reverting to the pre-remedied state. Description of Remedy : Description of Remedy Program : The inner valve stem extension and stabilizer will be removed. Repairs will be performed by Daimler Trucks North America authorized service facilities. Details of the reimbursement plan will be included in the owner’s notification letter. How Remedy Component Differs from Recalled Component : NR Identify How/When Recall Condition was Corrected in Production : NR Recall Schedule : Description of Recall Schedule : Customer notification will be made by first class mail using Daimler Trucks North America records to determine the customers affected. Planned Dealer Notification Date : JAN 21, 2022 – JAN 21, 2022 Planned Owner Notification Date : JAN 21, 2022 – JAN 21, 2022 * NR – Not Reported

Production Dates : FEB 20, 2017 – NOV 17, 2021 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : On affected chassis, the tire valve stem extension for the inner wheel may contact the outer wheel rim opening and become damaged. Damage to the valve stem extension may result in a loss of tire pressure of the inner wheel. This is a follow-on recall to 20V529 (DTNA # FL861), improving the remedy. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Damage to the tire’s valve stem may lead to loss of air pressure, which, if unnoticed, could lead to a flat tire or on dual-wheels an overloaded tire. In extreme situations, rapid loss of tire pressure could increase the risk of a crash. Description of the Cause : NR Identification of Any Warning that can Occur : Operators may identify an audible rattling noise from the stem extension rubbing against the wheel opening while driving. Visual inspection during inspection or during maintenance may reveal stabilizer is dislocated, damage to the stem extension, or the rim, and low tire pressure of the inner tire.

At the time of the original recall, based upon the information available at the time, DTNA reasonably believed its original defect remedy to be adequate. Based upon the more recent information, however, DTNA promptly opened an investigation and began reviewing the information from these VOQs. In late September, DTNA received an additional VOQ with a similar complaint with additional information that caused the scope of the investigation to widen. In October of 2021, DTNA received an additional VOQ and continued investigating. In November of 2021, DTNA reviewed Part 573 Safety Recall Report 21V-921 Page 6 The information contained in this report was submitted pursuant to 49 CFR §573 Customer and dealer complaint tickets and discovered possible instances where the previous recall remedy may not have been completely effective. In mid-November, out of an abundance of caution, DTNA decided to conduct a recall to institute a different remedy. Description of Remedy : Description of Remedy Program : The inner valve stem extension and stabilizer will be removed. Repairs will be performed by Daimler Trucks North America authorized service facilities. Details of the reimbursement plan will be included in the owner’s notification letter. How Remedy Component Differs from Recalled Component : NR Identify How/When Recall Condition was Corrected in Production : NR Recall Schedule : Description of Recall Schedule : Customer notification will be made by first class mail using Daimler Trucks North America records to determine the customers affected.
