Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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 of 5 mph in less than a couple hundred miles, and then the engine SHUTS DOWN. …”
