2020–2022 Cummins Power Generation Generator Set: Equipment recall

NHTSA campaign 22V464000 · 128 units potentially affected · filed Jul 6, 2022

What's wrong

Cummins, Inc. (Cummins) is recalling certain 2020-2022 Cummins Power Generation C500D6Re trailer-mounted generator sets (gensets). Incorrect logic in the output box door switch may cause the gensets to not shut down as intended when operated in parallel with other gensets.

Why it matters

The operator may be unaware that the gensets did not shut down, which could result in burns, electrical shock or arc flash, increasing the risk of injury.

The fix

Cummins will repair the electrical circuit, free of charge. Owner notification letters were mailed August 22, 2022. Owners may contact Cummins customer service at 1-800-286-6467.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
