What's wrong?
On affected 2020 Thor Sequence motorhomes, the solar panel sits on the luggage rack and is supposed to stay fixed to that rack while the motorhome is moving. The fasteners do the holding work: they clamp the panel to the rack so road vibration, wind, and normal travel do not shift it.
Thor found that these motorhomes were built with self-tapping screws securing the solar panel instead of the specified plates, carriage bolts, washers, and locking nuts. Those screws loosen or fail under use. Once the fasteners stop holding, the solar panel becomes loose, unfastened, or detached from the luggage rack, with the wiring left to catch the panel.
There is no warning sign before failure. An owner should not count on noise, movement, or a visible gap before the panel comes loose.

What's the safety risk?
A solar panel that detaches from the luggage rack becomes a road hazard for traffic behind the vehicle and increases the risk of a crash. Until the repair is complete, drive cautiously and schedule service soon. Repair is free at any franchised Thor dealer.
What should I do?
- Check your VIN to confirm your 2020 Thor Sequence is included in this recall.

- Bring the recall notice if Thor mailed one. If not, reference recall number 19V789 and Thor recall RC000179 when you call.
- Avoid travel if the solar panel or luggage rack hardware looks loose, and ask the dealer before driving the motorhome.
