End: 2023 Make: Freightliner Model: Business Class M2 Production Dates: Begin: Feb 1, 2022 End: May 14, 2022 Descriptive Information: On certain vehicles, a steering component upper U joint pinch bolt may not have been properly installed and inspected. Basis for Determination of the Recall Population: Trucks built in one particular plant during the time period above that experienced a discrepancy in the steering components may not have been properly inspected for joint integrity. Number potentially involved: 3,578 vehicles Estimated percentage of involved with defect: 1% Defect / Noncompliance Description For this Defect/Noncompliance: Describe the defect or noncompliance: On certain vehicles, the Upper U Joint pinch bolt on the steering shaft may not have been properly inspected, thereby creating a risk that some small fraction of vehicles left the manufacturing line with the bolt improperly installed. Describe the safety risk: Improperly inspected joints increase the chances of an improperly installed joint. An improperly installed joint could disconnect leading to a loss of steering control and increase the risk of a crash. Identify any warning which can precede or occur: Regular maintenance intervals and pre-trip inspections require steering component inspections. It may be possible to detect loose components during routine inspections. Additionally the defect might be detected by visual recognition of the spline sticking out from the joint or from the pinch bolt groove being mislocated. If applicable, identify the manufacture of the defective or noncompliant component.: This is not applicable because the components involved were not defective. Involved Components Component Name: Pinch Bolt Component Description: Upper U Joint Connection to Stub Shaft with Pinch Bolt Component Part Number: 14-18771-000 Chronology of Defect / Noncompliance Determination Provide the chronology of events leading up to the defect decision or test data for the noncompliance decision: On or around April 15, 2022 DTNA received a report of a missing pinch bolt in the steering system.

Also, check for a completion sticker prior to beginning work. U.S. and Canadian dealers, contact the Warranty Campaigns Department via Web inquiry at DTNAConnect.com/WSC, if you have any questions or need additional information. Export distributors, submit a Web inquiry or contact your International Service Manager. U.S. and Canadian Dealers: To return excess kit inventory related to this campaign, U.S. dealers must submit a Parts Authorization Return (PAR) to the Memphis PDC. Canadian dealers must submit a PAR to their facing PDC. All kits must be in resalable condition. PAR requests must include the original purchase invoice number. Export Distributors: Excess inventory is not returnable. The letter notifying U.S. and Canadian vehicle owners is included for your reference. Please note that the National Traffic and Motor Vehicle Safety Act, as amended (Title 49, United States Code, Chapter 301), requires the owner’s vehicle(s) be corrected within a reasonable time after parts are available to you. The Act states that failure to repair a vehicle within 60 days after tender for repair shall be prima facie evidence of an unreasonable time. However, circumstances of a particular situation may reduce the 60 day period. Failure to repair a vehicle within a reasonable time can result in either the obligation to (a) replace the vehicle with an identical or reasonably equivalent vehicle, without charge, or (b) refund the purchase price in full, less a reasonable allowance for depreciation. The Act further prohibits dealers from selling a vehicle unless all outstanding recalls are performed. Any lessor is required to send a copy of the recall notification to the lessee within 10 days. Any subsequent stage manufacturer is required to forward this notice to its distributors and retail outlets within five working days.
