NHTSA's recall notice
As NHTSA's recall record states it for campaign 17V634000.
Defect description
Thor Motor Coach (TMC) is recalling certain 2017-2018 Challenger, Axis, Chateau, Four Winds, Hurricane, Miramar, Palazzo, Tuscany, Vegas, Venetian, and Windsport motorhomes. The cargo carrying capacity (CCC) label on these vehicles may indicate an incorrect water capacity for the water heater/fresh water tank. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 120, "Tires and Rims for Motor vehicles over 10,000lbs."
Safety consequence
If the water capacity information is incorrect and it causes the vehicle to be over loaded, there would be an increased risk of a crash.
Manufacturer remedy
TMC will notify owners and send them corrected labels, free of charge. The recall began on November 15, 2017. Owners may contact TMC customer service at 1-877-500-1020. TMC's number for this recall is RC000147.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
