Bulletin Summary
Daimler Truck North America on behalf of its Freightliner Trucks Division and wholly owned subsidiaries have issued NHTSA #24C-392 and #24V-393 on certain 2025 model year vehicles. The affected vehicles may be missing the snap ring on the preset hubs and/or have unbent retainer tabs on the conventional 4-piece fastener hubs. This could allow the wheel hub fasteners to loosen. Wheel separation may occur resulting in an increased risk of loss of vehicle control and a crash.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
