Cummins Power Generation Generator SET Recall 22V464: Generator may not shut down, risking burns or shock

NHTSA campaign 22V464, reported July 6, 2022, 128 vehicles potentially affected.

What this recall means for you

Certain 2020-2022 trailer-mounted generator sets have incorrect logic in the output box door switch. When these units are operated in parallel with other generator sets, they may not shut down as intended, and the operator may not realize it.

If a generator keeps running or energized when the operator believes it has stopped, the result could be burns, electric shock, or arc flash, which increases the risk of injury.

Cummins will repair the electrical circuit free of charge. Owners who received the notification letter mailed August 22, 2022 can contact Cummins customer service at 1-800-286-6467. You can also check your vehicle identification number (VIN) for open recalls and have the repair done at an authorized dealer.
