What's wrong?
The wiring harness on the 2022-2024 Cummins Power Generation Generator Set carries electrical power and signals to parts of the trailer-mounted C275D2RE generator. Near the starter motor, those leads need to stay routed and secured so the insulation does not rub against the starter housing or terminal.
On affected units, assembly instructions did not fully control how the harness leads were routed and tied down. Loose or exposed leads can chafe against the starter motor housing or terminal stud until the insulation wears through. Once bare wire reaches metal, the circuit can short, blow a fuse, heat the wiring, damage the harness, or start smoke or fire.
Operators, bystanders, or service personnel can smell smoke before the hazard develops further. Service personnel can also find blown fuses or hot wires during maintenance, which are warning signs that the harness leads have been rubbing where they should not touch.
Who's affected?

What happens at the repair
Once Cummins Power Generation opens the final repair, a Cummins Power Generation technician will inspect the generator set wiring harness, repair damaged wiring, and secure the wiring leads so they do not rub against the starter motor housing or terminal. The final repair will be free once available. Cummins is not offering a separate reimbursement program because any product failure before the recall notice would have been handled under the manufacturer's limited warranty. Ask the warranty repair location how existing warranty coverage applies if you have prior repair paperwork.
