NHTSA Complaint #11425265 — 2018 NEWMAR DUTCH STAR

The failure has occurred in the emission system. The DEF SENSOR set off 2 Check Engine light warnings on the dash. It did not tell me any other information. I was fortunate to return from my trip without incident. However, after speaking with the chassis manufacturer (Spartan), I was fortunate to be able to continue. Had I gone any further the engine would have begun a shutdown leaving my 24 ton RV stranded roadside. It could have been very serious breakdown on a metro highway causing major traffic jams or left stranded in a remote location. The component required for replacement is not available till late Aug or Sept. As we live full time in the RV we are now stranded unable to travel until the part is available. Although our example appears to be an inconvenience we have dozens of other RVers experiencing this same problem and unaware of being stranded until the failure occurs. Whatever is causing the failure of these DEF sensors, owners should be notified and a general recall for replacement should be issued.
