New Truck Recall Affects Nearly 3,900 Freightliner and Western Star Vehicles
Daimler Truck North America (DTNA) is recalling 3,894 Freightliner and Western Star trucks due to a potential driveline defect. The problem could cause affected vehicles to lose drive power while traveling, increasing the risk of a crash.
The National Highway Traffic Safety Administration (NHTSA) acknowledged the truck recall on November 10, 2026, following the manufacturer’s November 6 report. The recall covers certain 2027 commercial vehicles equipped with specific Cummins drivelines. Repairs will be provided at no cost to vehicle owners.
Truck Recall Covers Seven Commercial Vehicle Models
The recall affects several Freightliner and Western Star models used in long-haul trucking, regional transportation, construction, and other commercial operations.
The affected 2027 models include:
- Freightliner Cascadia
- Freightliner Cascadia Fifth Generation
- Freightliner 114SD
- Freightliner 108SD
- Freightliner Business Class M2
- Western Star 47X
- Western Star 49X
Although seven models are included in the recall, not every vehicle from these model lines is affected. The recall applies specifically to trucks equipped with certain Cummins driveline assemblies. Vehicle identification numbers (VINs) can help owners and fleet managers determine whether individual trucks are included in the recall.
Driveline Defect Could Increase Crash Risk
According to NHTSA, the affected drivelines may have a missing snap ring within the slip yoke assembly. This defect could allow the driveline to separate from the vehicle.
The driveline transfers power from the transmission to the drive axles, allowing the truck to move. The slip yoke helps accommodate changes in driveline length as the vehicle’s suspension moves during operation.
A snap ring is a retaining component that helps keep parts in their intended positions. Without it, components within the assembly may separate.
NHTSA identified two primary safety risks associated with the defect:
- A separated driveline could interrupt power delivery to the wheels, increasing the likelihood of a crash.
- Components that fall from the truck could create dangerous obstacles for other motorists.
These risks are particularly concerning on highways, where commercial vehicles often operate at higher speeds and in heavy traffic. The recall acknowledgment does not specify how many trucks have experienced driveline separation or whether the defect has resulted in crashes or injuries.
Cummins to Provide Free Inspections and Repairs
Cummins will be responsible for inspecting the affected drivelines and replacing them when necessary. Both inspections and required replacements will be performed free of charge. The repair process will determine whether the affected assembly needs replacement. The official recall acknowledgment does not provide an estimated repair time or indicate how long replacement parts may take to become available.
For trucking companies and independent owner-operators, scheduling recall repairs may require adjustments to regular operations. Vehicle downtime can affect delivery schedules, equipment availability, and operating revenue, even when the manufacturer covers repair costs.
Truck Recall Notifications Expected in January
Owner notification letters are expected to be mailed on January 5, 2027. These notifications should provide additional information about the recall and instructions for arranging inspections and repairs. Vehicle owners can also contact the manufacturers directly for information about the affected equipment.
The following contact information is available:
- Daimler Truck North America: 1-800-547-0712
- Cummins customer service: 1-800-286-6467
- NHTSA Vehicle Safety Hotline: 1-888-327-4236
Daimler Truck North America has assigned the recall identification number F1046.
The NHTSA campaign number is 26V737000.
Both identification numbers can help owners locate information about the specific recall when contacting manufacturers or service providers.
How Truck Owners Can Check for Open Recalls
NHTSA maintains an online recall database that allows vehicle owners to search for unrepaired safety recalls using a vehicle’s 17-character VIN.
The VIN is typically available on vehicle registration documents and manufacturer identification labels.
Searching by VIN is important because recalls often affect specific production groups or equipment configurations rather than every vehicle within a particular model year.
However, newly announced recalls may not immediately include every affected VIN in the database. Manufacturers may need additional time to identify all vehicles involved.
Fleet managers can also contact manufacturers or authorized dealerships to confirm whether trucks in their fleets require inspections or repairs.
Federal Requirements for Recalled Trucks
NHTSA’s acknowledgment also reminds the manufacturer of federal restrictions involving vehicles with known safety defects.
Federal law generally prohibits manufacturers from selling or introducing affected vehicles into interstate commerce before completing the required repairs.
The manufacturer must also submit regular reports to NHTSA documenting the progress of the recall.
These requirements help federal regulators monitor whether manufacturers are notifying owners and completing necessary safety repairs.
Why the Truck Recall Matters for Commercial Drivers
The latest recall highlights the importance of monitoring equipment safety notices, including those involving recently manufactured commercial vehicles.
All seven affected models are from the 2027 model year, demonstrating that safety defects can also occur in new equipment.
While routine vehicle inspections remain an important part of commercial truck safety, some manufacturing defects may require specialized inspections to identify.
For motor carriers and owner-operators operating affected Freightliner and Western Star trucks, confirming recall eligibility and coordinating necessary repairs will be important steps in addressing the potential driveline defect.
