Cummins X15 Fuel Pump May Fail: More Kenworth, Peterbilt Recalls

NHTSA Campaign Highlights Fuel Pump System Safety Risks

PACCAR Incorporated is conducting a safety recall of certain 2025 truck models due to a fuel system defect that could lead to engine stalling, increasing the likelihood of accidents. The recall, listed under NHTSA Campaign Number 24V789000, specifically targets trucks equipped with Cummins X15 diesel engines, where fuel pump barrels may fracture and cause fuel leakage.

Impacted Truck Models

The recall affects a range of Kenworth and Peterbilt trucks manufactured by PACCAR. A total of 5,690 units are impacted, including:

• Kenworth: C500, T680, T800, T880, W900, W990
• Peterbilt: 567, 579, and 589

The defect lies in the diesel fuel pump system, which could cause the engine to stall unexpectedly. Engine stalls on highways or during critical maneuvers significantly increase the risk of a crash, posing serious safety concerns for both drivers and other motorists.

Remedy for the Fuel Pump Defect

PACCAR has taken steps to mitigate the problem by offering free replacements for the defective fuel pump barrels. Truck owners are urged to visit authorized dealers for the repair at no cost. Owner notification letters are scheduled to be mailed on December 22, 2024, ensuring that drivers and fleet operators are aware of the necessary steps to address this issue.

If truck owners have questions or need further information, they can contact:

• Kenworth Customer Service: 1-425-828-5888
• Peterbilt Customer Service: 1-940-591-4220
