- The problem
- PACCAR Incorporated (PACCAR) is recalling certain 2017-2019 Kenworth C500, T600, T660, T680, T800, T880 and W900 trucks, as well as Peterbilt 367, 386, 389, 567, 579 and 587 trucks, equipped with Cummins ISX15 or X15 diesel engines. In certain driving conditions, such as on a long down-hill grade, the fuel line may burst if the fuel pump cooling circuit screen becomes restricted.
- The risk
- If the fuel line bursts, fuel may leak onto the road resulting in a roadway hazard for other motorists. The engine may also stall without warning, resulting in the vehicle's inability to restart, increasing the risk of a crash.
- The fix
- Cummins will notify owners, and dealers will replace the suspect fuel pump cooling circuit screen, free of charge. The recall began November 21, 2018. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 18E081.
