What owners reported to NHTSA
12/02/2023, WHEELS: TPMS not reading tire pressure
11/23/2024, SERVICE BRAKES,FORWARD COLLISION AVOIDANCE: Last week I had the air dryer filter replaced at Colton Truck Terminal in Colton Ca. Subsequently, I did the complete 7 step air brake system check and discovered that during total loss of air pressure , the emergency brakes would not auto apply. I replaced the dash hand valve and the problem still persists, so I installed the original valve and took the coach back to Colton Truck Terminal to diagnose the problem.

More importantly I was exiting the highway and the steering wheel turned by itself back to center while I was

This feature is known as Comfort Drive or Comfort Steer. As I was driving down the highway at 60 MPH, I got a warning on the dash that said “Steering Effort Control (CTRL) Disabled” and the steering wheel immediately went into the very hard steering feel. Wh
07/15/2021, ENGINE: I recently purchased a 2021 Newmar Dutchstar Motorhome, and took delivery recently. The Diesel Exhaust Fluid (DEF) sensor failed in less than 3,000 miles. As a newbie in the motorhome world, I was stunned and very disappointed that this failure occurred so quickly, and also with the ramifications of the failure. When DEF sensors fail the engine can go into derate state which can cause my coach to move at a maximum o
