NHTSA's recall notice

Defect description
Thor Motor Coach (TMC) is recalling certain 2019 Thor Four Winds, Chateau, Freedom Elite, Majestic, Outlaw, Quantum and Vegas motorhomes built on modified Ford E-450 chassis. The U-bolts on the rear axle that hold the leaf spring and rear axle together may have been insufficiently tightened.
Safety consequence
The loose U-bolts may further loosen or break allowing the axle to separate and cause a loss of control, increasing the risk of a crash.
Manufacturer remedy
TMC has notified owners, and dealers will tighten U-bolts to the proper torque, free of charge. The recall began on June 22, 2018. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000156.
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.
