Summary: Thor Motor Coach (Thor) is recalling certain 2020-2021 Daybreak, Four Winds, Quantum, Delano, Tiburon, Chateau and Freedom Elite motorhomes and 2020 Gemini, Chateau Citation, Compass, Siesta, and Synergy motorhomes built on Sprinter Van chassis (platform 970 (VS30), equipped with swivel seats. The wiring harnesses for the front seats may have been routed incorrectly and could become jammed and damaged in the swivel seat frames.
Consequence: If the wiring harness is damaged, the side air bag within the seat may deploy inadvertently or not deploy as designed in the event of a crash, increasing the risk of injury to vehicle occupants.
Remedy: Thor will notify owners, and Mercedes-Benz dealers will inspect the wire harness routing for both front seats and will repair the wiring and add clips or cable ties as needed, free of charge. This recall began August 13, 2020. Owners may contact Thor customer service at 1-877-855-2867 Mercedes-Benz customer service at 1-877-762-8267. Thor's number for this recall is RC000200.

Remedy: TMC will notify owners, and an authorized Mercedes-Benz dealer will inspect the brake hoses for chafing and replacement if necessary. The fender liner will also be altered to permit more clearance. All repairs will be performed free of charge. This recall began June 25, 2020.
