What's wrong?
The fuel pump on these 2018 Newmar King Aire, Essex, and London Aire motorhomes is part of the diesel fuel system. Its job is to move fuel to the Cummins engine at the pressure the engine needs to keep running. A drive gear turns the pump shaft, which keeps the pumping action in step with the engine.
On affected motorhomes, that fuel pump drive gear can slip on the shaft instead of turning it. When the gear spins loose, the pump loses its pumping function. The engine then loses fuel supply, stalls, and cannot be restarted until the failed pump is replaced.
There is no warning sign before failure. The first thing an owner notices is the engine stalling, followed by a no-restart condition after the motorhome comes to a stop.

What's the safety risk?
Fuel pump failure stops the engine and increases the risk of a crash. The engine can stall without warning and cannot be restarted, so treat any stall as a reason to get the vehicle off the road and call the dealer. Repair is free at any franchised Newmar dealer.

- Bring the recall notice if Newmar has mailed one. If not, reference recall number 17V413 when you call.
