A significant recall has been announced involving thousands of Kenworth and Peterbilt trucks due to a problem with the Cummins X15 engines. This issue previously led to recalls affecting Daimler Truck and Navistar vehicles.
According to documents from the National Highway Traffic Safety Administration, nearly 6,000 Kenworth and Peterbilt trucks from the model year 2025 are being recalled by Paccar. The affected models include:
- Kenworth C500
- Kenworth T680
- Kenworth T800
- Kenworth T880
- Kenworth W900
- Kenworth W990
- Peterbilt 567
- Peterbilt 579
- Peterbilt 589
These trucks are equipped with Cummins X15 diesel engines featuring specific fuel pumps. It has been identified that some fuel pump barrels were manufactured with parts that have low fatigue strength, increasing their risk of fracturing. This fracture could lead to a fuel leak, potentially causing an engine stall, thereby elevating the chance of a crash.
Vehicles experiencing this engine defect might show reduced performance or trigger a warning light when fuel pressure dips below the required level. The presence of diesel fuel may also be detectable by sight or smell.
Paccar, in collaboration with the engine manufacturers, will replace the faulty Cummins X15 fuel pump barrels at no cost. Owners will receive notification letters by December 22.
This recall forms a segment of a comprehensive equipment recall issued by Cummins in September, affecting over 9,000 Cummins X15 engines supplied to different vehicle manufacturers such as Navistar, Daimler Truck, Kenworth, and Peterbilt. Of the total recalled units, only about 3% are anticipated to have this defect.
On October 1, both Daimler Truck North America and Navistar initiated their recalls related to the Cummins X15 issue, affecting nearly 1,700 trucks collectively. Together with Paccar’s recall, the majority of the engines initially recalled by Cummins are now accounted for. These engines were sold not only to heavy-duty commercial truck manufacturers but also to several fire truck manufacturers.
