Paccar is recalling 1,737 Peterbilt and Kenworth trucks because a fuel pump defect could cause the engine to stall, increasing the risk of a crash.
The recall affects 2017-2018 Peterbilt 367, 389, 567, 579 and 587 models, and 2018 Kenworth C500, T680, T800, T880 and W900 trucks. These vehicles are equipped with Cummins ISX 15-liter engines, according to the National Highway Traffic Safety Administration.
The engines on these trucks have a fuel pump whose drive gear could spin loose on the drive shaft. If this happens, there would be a loss of pumping function which would cause the engine to stall without warning and the driver would not be able to restart it.
“An unexpected engine stall without the ability to restart may increase the risk of a crash or injury,” according to the recall report.
No crashes or injuries related to this defect have been reported.
The issue stems from a drive gear that was not properly assembled onto the drive shaft. Mechanics will fix the problem by replacing the fuel pump on the engine.
