- Summary
- On certain fifth wheel and travel trailers, the tailpipe used to release the exhaust from the generator was not long enough to reach the side of the trailer. Thor modified the tailpipe by placing an extension on the tailpipe. As a result, the generator's exhaust may be released under the trailer at the point of the modification.
- Consequence
- The tailpipe exhaust needs to be released away from the underside of the trailer.
- Remedy
- Dealers will replace the existing tailpipe. Owner notification began may 13, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact thor california at 1-888-697-8467, extension 215.
- Notes
- Customers can also contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

Has your Thor California 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 Thor California dealer can also check your VIN. Recall repairs are free.
