Plain-English summary

Thor Motor Coach is recalling certain 2020-2021 Daybreak, Four Winds, Chateau, Freedom Elite, and Quantum motorhomes built on a Chevrolet chassis. The affected component is the Battery Isolation Manager (BIM) / Battery Isolation Relay (BIR).

The BIM/BIR is not watertight when exposed to engine compartment heat. Water can get into the component and create electrical arcing, increasing the risk of a fire.

Approximately 1,074 units are affected. Owners will be notified. Dealers will replace the BIM/BIR with a Trombetta solenoid free of charge. The recall began January 13, 2021. Owners may contact TMC customer service at 1-877-855-2867 (TMC recall number RC000206) or the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or visit www.safercar.gov.
