The short answer
NHTSA received Thor Motor Coach’s report on Jun 8, 2018. Copied from NHTSA on Oct 26, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
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.
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.
