Summary
On certain motorhomes equipped with international thermal research (itr)hurricane hot water heaters, the electronic control board may adversely affect safety features in some of the systems protecting against overheating and potential fire situation.
Consequence
If the safety features do not shut down properly, the heating system can continue heating, possibly resulting in a fire.
Remedy
The defective electronic control board will be replaced. In the meantime, customers should turn the system off using the master on/off switch located on the side of the electronic control box which is adjacent to the heater. Owners who take their motorhomes to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact itr at 1-800-755-1272 or at winnebago at 1-641-585-3535.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Ultimate been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Ultimate dealer can also check your VIN. Recall repairs are free.
