What's wrong?
The stay rod, also called a v-rod, is part of the rear axle control system on 2015-2016 Newmar King Aire, Essex, and Mountain Aire motorhomes built on a Spartan chassis. Its job is to hold the rear drive axle in the correct position as the suspension moves and the motorhome accelerates, brakes, and turns. The axle depends on that rod staying firmly attached.
On these motorhomes, the fasteners that attach the stay rod to the rear drive axle were not installed with thread locker or were not tightened in the correct sequence. Thread locker helps keep a fastener from backing out under vibration. Without that secure installation, the fasteners can loosen, and the stay rod can disconnect from the rear drive axle. Once that happens, the rear axle can move in directions it is not meant to move, which can cause loss of vehicle control.
There is no warning sign before failure. The fasteners can loosen without a clear noise, light, or handling change before the axle connection comes apart.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific motorhome is included.
What's the safety risk?
If the fasteners loosen, the stay rod can disconnect from the rear axle and allow the axle to move freely, increasing crash risk. There is no warning sign before the fasteners loosen, so contact a dealer promptly if your VIN is included. Repair is free at any franchised Newmar dealer.
What should I do?
- Check your VIN to confirm your 2015-2016 Newmar King Aire, Essex, or Mountain Aire is included in this recall.
- Contact a franchised Newmar dealer to schedule the free rear-axle stay-rod fastener repair.
- Ask the dealer to replace the fasteners with thread lock and tighten them in the proper sequence and torque, so the stay rod stays secured to the rear drive axle.
- Bring the recall notice if Newmar or Spartan sent one. If not, reference recall number 15V411 when you call.
- Use extra caution until the repair is complete, because loose stay-rod fasteners can let the rear axle move freely.
What happens at the repair
At the dealer, a Newmar technician removes the fasteners that attach the stay rod, also called the v-rod, to the rear drive axle. The technician installs replacement fasteners with thread lock, tightens them in the required sequence, and verifies the required torque values. The recall repair is available now, and parts and labor are free. Ask the service desk to document the work on the repair order before you leave.
