Daimler Truck North America (DTNA) is recalling 2,592 vehicles equipped with certain Cummins L9 diesel engines because their remote fuel filter hoses may separate from the fitting, causing a fuel leak and an engine stall, according to National Highway Traffic Safety Administration (NHTSA) recall records reported this week.

The recall covers certain 2022–2025 Freightliner Business Class M2 trucks, 2023 Freightliner 108SD trucks, 2022–2027 Freightliner Custom Chassis (FCCC) XCM and XCR models, and 2024–2027 FCCC XCS and XBS models. NHTSA's campaign number for the DTNA recall is 26V-660, and DTNA's own recall number is F1042.

Safety regulators spell out the risk plainly: a fuel leak in the presence of an ignition source increases the risk of a fire, and an engine stall increases the risk of a crash. DTNA's recall stems from a Cummins recall issued in September covering about 39,052 L9 engines sold to several manufacturers. Land Line reported that no warranty claims or injuries related to the defect have been reported, and Daimler estimated only about 3 percent of the recall population is actually affected.

Drivers may get an early warning: reporting on the recall notes a low fuel pressure fault, FC559, can trigger a warning light, and anyone who sees or smells a fuel leak around the truck should seek repair. Cummins will replace the fuel hoses free of charge, with hoses using an improved crimp design.

Owner notification letters are expected to be mailed around November 20. Owners can contact DTNA customer service at 1-800-547-0712 with recall number F1042, or Cummins customer service at 1-800-286-6467 with recall number C7311.

For Punjabi owner-operators and fleets running Freightliner equipment, the check is quick: confirm whether your truck's engine is in the Cummins L9 population before your next long haul, and keep the recall numbers handy when you call — a stall at highway speed or a diesel leak is not a risk worth rolling with.
