The contact owns a 2022 Thor Motor Coach Magnitude. The contact stated that the solar inverter failed to function as intended. The contact was unable to turn off or turn off the inverter. The warning lights were illuminated. A mobile RV mechanic arrived at the residence and diagnosed the vehicle and determined that the inverter Freedom 2000 was underrated for the vehicle and the compartment was not vented for heat. The contact was informed that the compartment was extremely HOT, and the metal inside turned blue where the positive wire was attached to the bolt. The mobile mechanic stated that it was luck that the recreation vehicle did not catch fire. The inverter Freedom Xantrex 2000 was…

I stopped at a campground after leaving SC. Discovered a Thor factory solar panel had detached somewhere between SC and Arkansas. The mounting bracket was still attached to the roof but the bolts, washers and nuts were missing on 2 of the 4 mounts and the other mounts had loose components. It would have been a possible catastrophic event if it would have detached at highway speeds.

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 braceâessentially a stickâintended to wedge the front of the slide in place during transit. Since then, the issue has progressed. The rear of the slide is now also moving outward during travel, causing the front brace to fall out. As a result, the front shifts again, and the slide continues to bind. This…

The following severe safety defects were found on the motorhome: - The passenger side wall was NOT attached on the bottom to the frame. 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 cap is pulling away from the coach due to insufficient mounting screws on both sides, which could cause the front fiberglass cap to fall off on the road, causing an accident. - All compartments on the passenger side were not attached to the frame with any hardware. This was…

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 vehicle towed due to interstate lane closure (safety issue). The Rv was towed to Rudig Jensen Ford in New Lisbon Wisconsin. Over the next couple days it was determined it was a chassis fuse box failure that caused the failure. The fuse box was replaced and we left the dealership…

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. Iâve 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 to visually inspect the moldings that cover these screws and the molding will bulge out. bolt JPH
