- Summary
- Thor motor coach (tmc) is recalling certain recreational vehicles manufactured from March 9, 2010, through March 9, 2011. The wiring for the oxygen (O2) sensor that connects to the catalytic converter may not be properly secured. When not secured, wiring can fall onto the exhaust, melt, and short out causing a check engine light (cel) and, in some cases, the engine to shut down while driving.
- Consequence
- An engine shut down while driving increases the risk of a crash.
- Remedy
- Dealers will secure the oxygen sensor by installing a clamp and by adding an additional fastener free of charge. The safety recall began on March 31, 2011. Owners may contact tmc warranty service department at 1-877-500-1020.

- Owners may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

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