What's wrong?
The throttle circuit on the 2017 Newmar London Aire, Mountain Aire, King Aire, Essex, and Dutch Star is the wiring path that carries the accelerator pedal signal to the engine controls. When the driver presses the pedal, that circuit tells the engine how much throttle is being requested. The signal has to stay clean so the engine receives the same command the driver gave.
On affected motorhomes built on a Spartan Motors chassis, the throttle circuit wires were not twisted together as specified. Twisting the wires helps cancel electromagnetic interference, the electrical noise that surrounds wiring in a large vehicle. Without that protection, interference can make the throttle signal read higher or lower than the pedal input, leading to loss of throttle or unintended acceleration.
There is no warning sign before failure. The throttle response can change without a warning light, unusual noise, or pedal feel that gives the driver time to react.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific motorhome is included.
What's the safety risk?
Unintended deceleration or acceleration can raise crash risk because the coach changes speed without warning. If the vehicle surges, slows unexpectedly, or feels hard to control, pull over when safe and arrange service before driving farther. Repair is free at any franchised Newmar dealer.
What should I do?
- Check your VIN to confirm your 2017 Newmar London Aire, Mountain Aire, King Aire, Essex, or Dutch Star is included in this recall.
- Contact a Newmar dealer to schedule the free overlay-harness repair that corrects throttle-signal interference.
- Bring the recall notice if Newmar mailed one. If not, reference recall number 16V810 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance and avoid abrupt throttle inputs.
What happens at the repair
At the dealer, the technician installs an overlay harness with twisted wires in the throttle circuit so electromagnetic interference does not distort the throttle signal. The repair is free under the recall, with parts and labor covered. Newmar's general reimbursement plan is on file for owners who already paid for a related repair before the recall work was completed. If you have prior repair paperwork, ask Newmar customer service how that documented expense is handled under the plan.
