Freightliner Custom Chass is recalling 74 2017-2018 Xcp and Xcm chassis, along with 122SD, 4900, and 6900 trucks equipped with Cummins ISX15 engines, because a fuel pump drive gear can slip on its shaft. If the pump fails, the engine will stall without warning and cannot restart, increasing crash risk; the dealer repair is free.

What's wrong?

The affected 2017-2018 Freightliner Custom Chass Xcp, 122SD, 6900, Xcm, and 4900 trucks and chassis use Cummins ISX15 diesel engines. The fuel pump sends diesel fuel to the engine at the pressure it needs to keep running. Inside that pump, a drive gear turns on a drive shaft so the pump keeps moving fuel while the engine runs.

On these vehicles, the drive gear on the fuel pump can slip on the drive shaft. When that gear spins loose instead of driving the pump, the pump loses its pumping function. The engine is then starved of fuel and stalls because it no longer receives the fuel supply it needs.

What you notice is the stall itself. The engine can stall without warning, and once it stalls, it cannot be restarted until the fuel pump problem is repaired.
