Shortly after departing from J&J RV Park in Hot Springs, Arkansas, in my vehicle, a motorhome, two yellow check-engine lights illuminated on the dashboard. I continued driving for 52 miles to my next destination, Downtown Riverside RV Park in North Little Rock, Arkansas. The engine ran normally, and I arrived safely. I checked the vehicle's computer system on the dashboard and located three trouble codes: 3364, 1761, and 3031. I contacted the vehicle's chassis manufacturer, Spartan Chassis in Charlotte, Michigan, and was told the codes in…

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…

We got the check engine light on after starting up our coach on July 6. We got several fault codes: SPN 3364 FMI 9, SPN 1761 FMI 9, SPN 3031 FMI 9. The codes indicated that we had a faulty DEF Header and it needed to be replaced. And if we drove the coach at some point it would "derate" to 5 miles an hour and we would not be able to drive it. We were told by the chassis maker (Spartan) that we would likely not be able to get a replacement part until September or October due to the global microchip shortage. And even though there was no…

I was driving home this weekend in my motorhome and noticed smoke coming out of rear of vehicle. I thought we were on fire. Fortunately I was able to get off the road and no injuries occurred. However, there will be many injuries if this problem is not recalled. The vehicle has a Cummins ISL Diesel motor. Vehicle has 33K miles. The #1 fuel injector line fails. If you look online this has happened many of times. Cummins also has a TSB for failure. Also, the "revised" part comes with a new bracket to prevent future failure. So Cummins is aware of…

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. I contacted Spartan motors, the manufacturer of my ch…

I HAVE A 2016 NEWMAR DUTCH STAR MOTOR HOME MODEL 4018. IT'S A 40 FT LONG DIESEL PUSHER ON A FREIGHTLINER CHASSIS WITH TOYAL WEIGHT OF 39600 LBS.

Since purchasing this RV new, I have had the DEF Head fail twice. 1st time was Sep 2019 with a mileage of 14066 and the 2nd time was April 2021 with a mileage of 16018. Both times DEF Header Assemblies were replaced. When these fail the motor can de-rate at any time. Very dangerous when traveling down the highway. Both times the low DEF warning and check engine lights came on.

The 2023 Newmar Dutch Star 4326 with a Freightliner Custom Chassis was built without an exterior temperature gauge. This is the first vehicle I've seen like this in many years. I'm on our first trip with my family onboard and we're driving thru the NC mountains in a wintery mix with temperatures varying from above to below freezing. I'm very nervous not knowing when the roads will begin to ice over on treacherous roads. I've discussed with Newmar and Freightliner and they both just say they don't know why it's not there and that they cannot add…
