Thor is recalling 12 2018-2019 Palazzo and Aria motorhomes built on Daimler Trucks North America chassis because the steering and tie rod arm bolts on Detroit Axle front axles can be loose. If those bolts loosen, the tie rod arm can separate from the front wheels, raising crash risk, and Thor dealers will complete the repair free of charge.

What's wrong?
The 2018-2019 Thor Aria and Palazzo motorhomes use steering and tie rod arms at the front axle to turn the wheels when the driver moves the steering wheel. The tie rod arm connects the steering linkage to the wheel-end knuckle, the heavy joint that lets the wheel pivot while supporting the vehicle. Those bolts have to be tightened to the correct torque so the joint stays clamped together.
On affected motorhomes, production records did not verify that the steering and tie rod arm bolts received the required torque during assembly. A bolt that is not tight enough can loosen as the coach is driven. If the joint keeps moving under load, the tie rod arm can separate from the knuckle and the steering linkage no longer holds that wheel in its intended position.
There is no warning sign before failure. Loose steering or unusual front-end movement needs dealer attention, but the recall filing does not identify a reliable early symptom.

What's the safety risk?
Loose steering and tie rod arm bolts can let the tie rod arm separate from the front wheels. That loss of steering connection increases crash risk. Drive cautiously, avoid unnecessary trips, and schedule the inspection soon. A Thor dealer will check bolt tightness and replace fasteners if needed. Repair is free at any franchised Thor dealer.
What should I do?
- Check your VIN to confirm your 2018-2019 Thor Aria or 2019 Thor Palazzo is included in this recall.
- Contact a franchised Thor dealer or Daimler Trucks North America Qualified Service Center to schedule the free steering-arm and tie-rod-arm bolt inspection.
- Ask the service desk to tighten the loose steering and tie rod arm bolts and install new fasteners as needed.
- Bring the owner notice if you have it, and reference recall number 19V200 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance and avoid rough roads when practical.
What happens at the repair
At the dealer, a Thor technician inspects the steering arm and tie rod arm bolts to confirm they are properly tightened. If the fasteners are loose or need replacement, the technician installs new fasteners as needed. Parts and labor are free under the recall. If you've already paid out of pocket for this steering or tie rod arm bolt repair before the recall notice, TMC's general reimbursement plan covers documented expenses.
