Equipment · 2025-09-15 · NHTSA complaint #11687351
The coolant caused leaked out and the engine overheated and quit. Thor has acknowledged this problem, but Thor had no recall notice and will not cover the engine under warranty. This could have been a safety issue by starting an engine fire and having the vehicle stop in the middle of a state highway.
