My 2017 THOR Challenger was part of NHTSA recall 21V-845. I made repairs to my coach in 2017 and 2018 totaling $4600. I have sent THOR all pictures and receipts from those repairs. I started the process in March 2022. Last week they informed me it is not a Thor recall, and I would have to deal with the company that manufactured the doors for them. I have included recent correspondence with them. I can, if you request, send all my receipt and pictures for the repairs that i had done. I wish to file a formal complaint for the disregard of NHTSA recall 21V-845. Thank you, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). The dealer stated NHTSA 21V-845 was not a Thor recall and the consumer had 15 doors replaced at the owners expense totaling over $4600.
The contact owns a 2017 Thor Challenger Motorhome. The contact stated that while driving at 65 MPH, an abnormally loud banging sound was heard and another vehicle honked the contact, alerting him to look in the rearview mirror. The contact noticed styrofoam flying from the motorhome and the external compartment door flapping open. The contact pulled over and examined the RV and became aware that one of the external compartment door skin had separated from the glue. The contact used masking tape to tape the separated door compartment and four other door compartments that were starting to separate as well. The vehicle was not repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure but informed the contact that the warranty had expired. The contact related the failure to NHTSA Campaign Number: 21V845000 (Structure) however, the VIN was not included in the recall. The failure mileage was 19,100.
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
