What's wrong?

The park brake harness connects the parking brake signal to the motorhome's slide-out room controls. Its job is to tell the controls when the parking brake is engaged, so the room only moves when the motorhome is parked. On affected 2023-2026 Thor Motor Coach motorhomes, that lockout depends on the harness being wired and pinned correctly.

The problem is incorrect pinning in the harness. When the wiring is wrong, the control system receives the wrong parking brake signal, so the slide-out room can deploy even when the parking brake is not engaged. That defeats the intended safeguard and allows the room to extend while the motorhome is in motion.

The warning sign is specific. With the engine running, the transmission in park, and the parking brake disengaged, the slide-out room moves when you press the room control. If it moves in that condition, the harness is miswired. Do not push the slide-out button while the vehicle is in motion.

Who's affected?

Spans the Freedom Traveler, Freedom Elite, Axis, Vegas, Quantum, Outlaw, Geneva, Four Winds, Echelon, Coleman, Chateau, Pasadena, Magnitude, and Eddie Bauer model lines across the 2023-2026 model years, all tied to the Ford park brake harness.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific motorhome is included.

What's the safety risk?

A slideout room that extends unexpectedly increases crash risk. A slideout that moves with the engine running, transmission in park, and parking brake disengaged points to a miswired harness. Do not push the slideout button while the vehicle is in motion. Schedule the harness repair soon. Repair is free at any franchised Thor Motor Coach dealer.

What should I do?

  1. Check your VIN to confirm your 2023-2026 Thor Motor Coach Axis, Chateau, Coleman, Echelon, Eddie Bauer, Four Winds, Freedom Elite, Freedom Traveler, Geneva, Magnitude, Outlaw, Pasadena, Quantum, or Vegas is included in this recall.
  2. Contact a franchised Thor Motor Coach dealer to schedule the free park-brake-harness replacement that prevents the slide-out room from deploying while the motorhome is moving.
  3. Bring the owner letter if you have it, and reference recall number 25V171 when you call.
  4. Keep the slide-out room fully retracted before driving, and confirm the parking brake is engaged before operating the slide-out.
  5. Call Thor Motor Coach customer service at 1-877-855-2867 with questions about TMC recall RC000325.
