2022 Thor Motor Coach Magnitude Problems

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 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 presents a serious safety risk. The slide can extend beyond the vehicle’s sidewall while in motion, increasing the chance of contact with nearby vehicles or objects. It also poses a structural integrity concern and could prevent safe egress in an emergency. There are no warning lights or error messages. The problem has been present since delivery, and has been inspected and documented by the manufacturer, but remains unresolved. The component is available for inspection upon request. This is a recurring and worsening failure affecting safety and basic function. Reports from other owners suggest this may be a broader design or manufacturing defect.

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 discovered when suddenly on a trip a weird noise was heard from tailpipe. The compartment had fallen on the tailpipe and was vibrating. This could have caused a fire resulting in total loss of the RV endangering the occupants or dropping debris on the road that could have caused an accident. - The main support beam, where it connects vertically to the horizontal beam, behind the drivers seat next to the wall slide was only poorly mig welded on one side with a poor spot weld on another, not all four sides as a support beam should be. The beams over time have flexed and broken the weld. This could have caused a failure of the driver's wall, falling off along with the occupants at dinette. In an accident, the motorhome would have crushed my children and endangered other vehicles on the road. Each failure has been recorded with photos and video. The repairs can be inspected along with the detached wall. The vehicle was taken to a dealer for diagnosis but refused to fix the beam failure. It was welded by a professional who could confirm the diagnosis. The cap issue is common among many vehicles and is known by most dealers and the manufacturer. The symptoms appeared when checking the vehicle on a stop when cracks in the side frame were found. The other failures were found during inspection

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 replaced with an inverter Freedom Xantrex 3000. The manufacturer was notified of the failure and informed the contact that the warranty had expired and offered no assistance. The failure mileage was 28,846. The VIN was not available.

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.

Multiple power train failures while driving on interstate shutting down Highway due to the inability to move vehicle. 6 instances now where I have received warning lights of hill assist, traction control, collision control and other features being disabled while moving.

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 with Jeep in tow, 8 miles down the road on I90W we were at highway speed (approximately 65 mph) and had exact same failure. Knowing what was happening, I was fortunate to be able to drift over into the emergency lane this time. Once again the Rv was towed to Rudig Jensen Ford. The Rv was diagnosed with exact same problem, fuse box failure. The fuse box is scheduled to be replaced today July 10th. When this incident happens it’s immediate loss of forward movement due to the transmission jumping into neutral. The Rv can not be moved and once turned off can not be restarted. This type of situation could be disastrous or even deadly. Entire interstate had to be shut down to have my vehicle towed.
