What's wrong?
The front seat wiring harness in these 2020-2021 Coachmen Galleria, Prism, Forester, Sunseeker, and Isata motorhomes is the bundle of electric lines that supplies and controls functions in the driver and passenger seats. On Sprinter Van chassis with swivel seats, that wiring also includes circuits tied to seat equipment such as the side airbag system. It needs to stay clipped in the correct path while the seat turns and moves.
The problem is routing. The harness was installed outside specification, and a cable was not secured where it was expected to be. As the swivel seat frame moves, the loose or misrouted harness can get jammed in the frame and become damaged. Damaged wiring can interrupt the seat electrical functions or the side airbag circuit.
The warning sign is the SRS indicator lamp. If the side airbag wiring is affected, that light turns on and stays on until the wiring condition is repaired.
Who's affected?
Spans five model lines across the 2020 and 2021 model years, with the same front seat wiring harness tied to seat, side air bag, and wiring components.

What's the safety risk?
A damaged seat wiring harness can make the side air bag deploy without a crash or fail to deploy as designed during a crash, increasing injury risk for occupants. If the SRS indicator lamp stays on, treat it as a warning sign and schedule the recall inspection promptly. Repair is free at any franchised Coachmen dealer.

What happens at the repair
At the dealer, a Coachmen technician inspects the wire harness routing for both front seats. If the harness was routed into the swivel seat frame or shows damage, the technician repairs the wiring and adds clips or cable ties to keep it secured. The recall repair is free at the dealer now. If you paid out of pocket for the same front-seat wiring repair before the recall notice, the manufacturer's standard reimbursement plan covers documented expenses. Bring that paperwork to the service desk when you ask about the recall repair.
