16V260000 · Seat Belts
Reported: 2016-04-29 (April 29, 2016)
Thor Motor Coach (TMC) is recalling certain model year 2017 ACE and Road Bear Rental motorhomes manufactured February 11, 2016, to March 9, 2016. The seat belt anchorages located in the slide out section may not meet the specified strength requirements, allowing them to pull loose during a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 210, "Seat Belt Assembly Anchorages."
Consequence: If the seat belt anchorages pull loose in a crash, they will not properly restrain the occupant, increasing the risk of injury.
Remedy: TMC will notify owners, and dealers will install reinforcement brackets, and plates, free of charge. The recall began on May 27, 2016. Owners may contact TMC customer service at 1-877-500-1020.

Reported: 2017-04-10 (April 10, 2017)
