What owners reported to NHTSA
09/01/2022, EQUIPMENT: The contact owns a 2022 Thor Motor Coach Magnitude built on a 2021 Ford F-550 chassis. The contact stated that while driving at an undisclosed speed, the slide-out room experienced unexpected movement. The RV was taken to the dealer where it was diagnosed that the slide-out track system needed to be replaced. The RV was not repaired. The manufacturer was made aware of the failure. The contact related the failure to N
08/13/2021, STRUCTURE: After driving from California to New York, I saw that screws holding the Front Cap (cab over bunk) had started to back out and delaminated the trim. If the screws continue to back out, it is possible that the entire front cap attached to the Ford Chassis could break apart from the RV and injure the passengers or people on the road. I have reported this issue to Thor and I am awaiting feedback if they are able to r
07/11/2022, POWER TRAIN,BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE: On July 4th I was merging into traffic onto I90W when my vehicle warning lights started flashing across the full spectrum. The gear shift show no indication of gear position and the Rv appeared to have jumped into neutral as I was accelerating and merging. The vehicle would not move forward causing full lane closure. I was flat towing a 2010 Jeep Wrangler. Law Enforcement arrived on scene and immediately had the

The mounting locations are missing all mounting hardware from the factory. The wall is breaking away from the roof where it is the only location anchored. If it wasn't discovered, the whole side wall may fall off endangering the occupants and other vehicles on the road. -The front ca
06/04/2025, STRUCTURE,EQUIPMENT: The primary issue involves the large, full-wall slide-out system on our motorhome. Since new, the front portion of the slide has shifted outward during travel, even while fully retracted. This led to the slide binding and becoming inoperable. The manufacturer attempted to fix the issue twice at their factory service center. Their most recent solution involved providing a makeshift brace—essentially a stick—intended
04/07/2022, STRUCTURE: Screws that hold the rv body together at the corners are breaking off and /or backing out. If all these screws come out which they are known to the body could fall apart going down the highway. I’ve read forums where everyone that has submitted complaints are experiencing this problem on all Thor Motorcoach models, Omni and Magnitude. Thor is totally aware of this problem. The only way to tell this problem exists is
