(9899 W Roosevelt St, Tolleson, AZ 853530 for assistance. In spite of the referral, the tire pressure monitoring system for the passenger's side rear outer tire remained defective. The vehicle had yet to be repaired. The failure mileage was approximately 1,800.
While driving across Florida, the "Check Engine" light and first of three DEF Head "Service Codes" on our 2018 Entegra Cornerstone 45' RV came on, indicating that our Diesel Exhaust Fluid (DEF) system had an issue. From previous social media posts from other Entegra Owners, we immediately contacted the chassis manufacturer, Spartan. They requested that we contact Cummins-Orlando, FL for a DEF Head replacement. Cummins-Orlando said they couldn't get us in for three weeks, which wasn't an option, as we were...

traveling and couldn't wait three weeks. We contacted Cummins-Tampa, FL and Cummins-Jacksonville, FL, with both stating 2-3 weeks to get us in. By this time, the second of three DEF codes came on, so the situation was getting more dire. We finally got through to Cummins-Ocala, FL and they were able to squeeze us in the next day. The third of three DEF Codes came on during the relatively short drive to Ocala, FL, but we were able to get there before the RV went into "limp mode" which restricts your speed to 5mph!! We were extremely worried about being stranded on the busy interstate Highway in a vehicle the size of a Greyhound Bus, limping along at 5mph with 18-wheelers whizzing by at 70-75mph! This DEF Head issue has been going on for several years and doesn't seem to be getting any better, even though the manufacturer is on their 7th Generation of DEF Head technology. Luckily, Spartan had the DEF Head in-stock and was able to overnight it to Cummins-Ocala, but many others have been held up for days/weeks due to a back order on the replacement DEF Heads. I feel that a recall should be issued on all DEF Heads prior to the 7th Generation, in order to avoid the safety issues associated with being stranded on the highway with a failed DEF Head.
The contact owns a 2017 Spartan Entegra Cornerstone RV. The contact stated while starting the RV to leave a campsite, he became aware that the check engine warning light was illuminated. The contact took the vehicle to the local dealer who inspected the vehicle and diagnosed the failure as a diesel exhaust fluid (DEF) system sensor head that needed to be replaced. The dealer replaced the sensor system however, the failure recurred. The vehicle was taken back to the same dealer and the sensor was replaced again. The contact was concerned that the failure would recur. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 35,000.
Def head sensor failure causing an unsafe derate condition. The rv will only go 5mph causing me to not be able to get to a safe location. As i understand the engine and def system are functioning as they should but the malfunctioning sensor has caused the engine to shut down or derate to 5mph.
Vehicle has approximately 30,800 miles. A check engine light with error codes SPN: 3364, 1761, 3331 indicating a failure of the DEF ( diesel exhaust fluid) sensor. This results in a degrade in performance to a point of engine shutdown. Replacement parts are very hard to obtain because this error is so common.
