Electrical system, Equipment, Feb 18, 2026
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.
Equipment, Other or unspecified, Feb 18, 2026
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.
Structure, Equipment, Jun 4, 2025
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.
Equipment, Sep 1, 2022
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 NHTSA Campaign Number: 19V504000 (Equipment) however, the VIN and model year was not included in the recall. The failure mileage was approximately 1,500.
