Thor recalls thousands of rigs: Slide-outs could extend while driving

More than 4,000 Thor-built motorhomes are being recalled out of concern that their slide-out rooms could extend while the rig is heading down the road. Thor Motor Company (TMC) is recalling certain 2023-2026 Axis, Chateau, Four Winds, 2023-2025 Coleman, Echelon, Freedom Elite, Geneva, Outlaw, Quantum, Vegas, 2025 Eddie Bauer, Freedom Traveler, Pasadena, and 2024-2025 Magnitude motorhomes.

The slide-out room can be deployed without the parking brake engaged, allowing the room to extend while the vehicle is in motion. A slide-out room that extends unexpectedly increases the risk of a crash. This Thor slide-out issue affects 4,251 motorhomes.

Thor slide-out remedy

Dealers will replace the park brake harness, free of charge. Owner notification letters are expected to be mailed May 5, 2025. Owners may contact TMC customer service at 1-877-855-2867. TMC’s number for this recall is RC000325.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 888-327-4236 (TTY 888-275-9171) or go to nhtsa.gov.

What’s with the Thor slide-out system?

As early as February 2023, Thor installed wiring harnesses on the affected rigs. The wiring should prevent the slide-out from being actuated unless the parking brake is engaged. The harnesses were wired incorrectly, so slide-outs can be actuated with the brake off.

Here’s how to know if your rig is wired wrong: With the engine running, the transmission in park, and the parking brake disengaged, attempt to cycle the slide-out rooms. If the slide-out moves, then the wire harness is miswired. Do not push the slide-out button while the vehicle is in motion.

Russ and Tiña went from childhood tent camping to RVing in the 1980s when the ground got too hard. They've been tutored in the ways of RVing (and RV repair) by a series of rigs, from truck campers, to a fifth-wheel, and several travel trailers. In addition to writing scores of articles on RVing topics, they've also taught college classes for folks new to RVing. They authored the book, RV Boondocking Basics.

Accidently opening is better than accidentally opening while towing or falling off.

C O M E O N ! When does this type of recall insanity end? Is this the first time that anyone has tried to put a slide out in an RV?

Thank you for the timely warning, Russ and Tina, and a bit more timely than will be the letter Thor will eventually send to affected owners. Well, I can’t say that this problem affects my opinion of Thor in the least; merely galvanizes it. Have a great day and safe travels!
