Defect / Noncompliance Information Report (Section 573.6) FL929 Date of Submission: April 22, 2022 Manufacturer: Daimler Truck North America LLC P.O. BOX 3849 Portland, Oregon 97208 Type of Report: x Safety Defect ⃝ Non-Compliance Vehicle Information Model Yr. Start: 2019 Model Yr. End: 2023 Make: Thomas Built Buses Model: HDX Production Dates: Begin: 03/28/2018 End: 03/23/2022 Descriptive Information: On certain Thomas Built Bus HDX model busses, the battery cables may potentially chafe on the transmission oil cooler hoses. NOTE:  Identify by body style or type. – HDX  If bus, include the number of passengers. 1-90 Basis for Determination of the Recall Population: At the current time, all HDX chassis built from March 20, 2018 to March 25, 2022 are included in the recall population. However, as DTNA continues to investigate, the population may be decreased. Number potentially involved: 138 Estimated percentage of involved with defect: 1% Defect / Noncompliance Description For this Defect/Noncompliance: Describe the defect or noncompliance: Certain HDX buses had the positive battery cable routed in a manner that permitted those battery cables to rub on the transmission oil cooler hoses, creating the possibility of an electrical fault or, in the extreme, a thermal event. Describe the safety risk: If the battery cable rubs on the hose long enough, there is a potential that after prolonged contact the hose could wear thru the electrical conduit, creating the risk of an electrical short or, in the extreme, a fire. Identify any warning which can precede or occur: DTNA reasonably expects this potential chafe should be detected during regular maintenance intervals. The maintenance manual specifically states to inspect the battery cables for chafing every 4,000 miles (6,400 Km) or 60 days. Because chafing must continue for a prolonged time and would show visible signs of chafing before electrical cables wear to the point of a safety risk, DTNA reasonably believes there would be many opportunities for detection and repair before the issue would rise to the safety risk described above occurring. If applicable, identify the manufacture of the defective or noncompliant component.: No components – DTNA assembly issue. Involved Components Component Name: N/A Component Description: N/A Component Part Number: N/A Chronology of Defect / Noncompliance Determination Provide the chronology of events leading up to the defect decision or test data for the noncompliance decision: In mid-February of 2022, DTNA received a report from the field of a potential thermal event on a three-year-old HDX school bus; according to the best of DTNA’s knowledge, no injuries or deaths occurred in this event. DTNA immediately began an investigation into the issue. No additional field reports or warranty claims of fire or similar symptoms were found. In early March of 2022, as soon as reasonably practicable to investigate the vehicle, DTNA’s Cause and Origin investigator examined the suspect bus and determined the origin of the thermal event was likely at the battery cable crossing over the transmission cooler hoses. Within that same month and lasting into April, DTNA began a comprehensive review of warranty data and field reports. Upon reviewing information more closely for this defect, DTNA found 17 total warranty claims ranging from November of 2018 to December of 2020 for the battery cables rubbing or contacting the transmission oil cooler hoses. None of these claims indicated any evidence of a fire or similar thermal event. Nonetheless, in April 2022, out of an abundance of caution DTNA decided to conduct a voluntary recall on certain Thomas Built Bus HDX chassis. There are no injuries or deaths reported. Identify the Remedy Describe the defect/noncompliance remedy program, including the manufacture’s plan for reimbursement. Inspection and repair of the cable routings, if required, will be performed by Daimler Truck North America authorized service facilities. Daimler Truck North America shall be offering a refund for owner-paid repairs covered by this recall if the repair was performed prior to the date indicated in the reimbursement plan, which will be posted with owner’s notification letter. Owners are directed to seek reimbursement through authorized dealers.

OMB Control No.: 2127-0004 Part 573 Safety Recall Report 22V-272 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : Daimler Trucks North America, LLC Submission Date : MAY 23, 2022 NHTSA Recall No. : 22V-272 Manufacturer Recall No. : FL928 Manufacturer Information : Manufacturer Name : Daimler Trucks North America, LLC Address : 4747 N. Channel Avenue Portland OR 97217-3849 Company phone : 800-745-8000 Population : Number of potentially involved : 138 Estimated percentage with defect : 1 % Vehicle Information : Vehicle 1 : 2019-2023 Thomas Built Bus HDX Vehicle Type : BUSES, MEDIUM & HEAVY VEHICLES Body Style : Power Train : NR Descriptive Information : Thomas Built Commercial Bus Production Dates : MAR 28, 2018 – MAR 23, 2022 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Certain HDX commercial buses had the positive battery cable routed in a manner that permitted those battery cables to rub on the transmission oil cooler hoses, creating the possibility of an electrical fault or, in the extreme, a thermal event. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : If the battery cable rubs on the hose long enough, there is a potential that after prolonged contact the hose could wear thru the electrical conduit, creating the risk of an electrical short or, in the extreme, a fire. Description of the Cause : NR Identification of Any Warning that can Occur : DTNA reasonably expects this potential chafe should be detected during regular maintenance intervals. The maintenance manual specifically states to inspect the battery cables for chafing every 4,000 miles (6,400 Km) or 60 days. Because chafing must continue for a prolonged time and would show visible signs of chafing before electrical cables wear to the point of a safety risk, DTNA reasonably believes there would be many opportunities for detection and repair before the issue would rise to the safety risk described above occurring. Part 573 Safety Recall Report 22V-272 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Involved Components : Component Name 1 : CLAMP-CABLE,NYLON,AWG 0000 Component Description : Battery Cable Clamp Component Part Number : DK 016 0020 Supplier Identification : Component Manufacturer Name : Hellerman Tyton Address : NR NR Country : NR Chronology : In mid-February of 2022, DTNA received a report from the field of a potential thermal event on a three-yearold HDX school bus; according to the best of DTNA’s knowledge, no injuries or deaths occurred in this event. DTNA immediately began an investigation into the issue. No additional field reports or warranty claims of fire or similar symptoms were found. In early March of 2022, as soon as reasonably practicable to investigate the vehicle, DTNA’s Cause and Origin investigator examined the suspect bus and determined the origin of the thermal event was likely at the battery cable crossing over the transmission cooler hoses. Within that same month and lasting into April, DTNA began a comprehensive review of warranty data and field reports. Upon reviewing information more closely for this defect, DTNA found 17 total warranty claims ranging from November of 2018 to December of 2020 for the battery cables rubbing or contacting the transmission oil cooler hoses. None of these claims indicated any evidence of a fire or similar thermal event. Nonetheless, in April 2022, out of an abundance of caution DTNA decided to conduct a voluntary recall on certain Thomas Built Bus HDX chassis. There are no injuries or deaths reported. In early May of 2022, in an effort to reduce the administrative burdens and to simply the reporting requirements, DTNA decided to merge recalls FL928 (22V271 – School Bus) and FL929 (22V272 Non School Bus). There are, materially speaking, no differences in the recalls except for the vocations of the population. To further clarify, the newly merged recall population will be designated as FL928A (22V271) for school bus vocations and FL928B (22V272) will be designated for commercial bus vocations. In addition, per a request from the Agency, a more concise description was added to the Involved Components section of the DIR filing.
