2016 ENTEGRA ANTHEM Engine Problems

The DEF head unit failed on our Anthem and left us stranded on the road. These DEF heads are failing on diesel motorhomes across the country putting consumers in often dangerous situations along the nations highways. Shaw Industries is the sole provider for Spartan Chassis emission systems. We like many we had to wait weeks to get a new one. We had to buy a 5th generation DEF head and these are the ones that fail the most. The 7th generation which supposedly is the only reliable DEF head won’t work on our 2016 Anthem. Now we run the risk of another failure and being stranded possibly 1000’s of miles from home. Shaw Industries and Spartan have no accountability or legal reason to be held financially liable since RV’s don’t fall under the automobile industries US code compliance. The EPA and NHSTA needs to get this issue resolved ASAP. My...

DEF Head failure, SPN 1761, FMI 3. Bad tank level sensor, will cause derate of engine performance/speed/rpm in an unknow future time period. Will take the unit down to 5 mph with little notice. During this time the DEF pump and after treatment process is continuing with no environmental effects, this is only a tank level sensor failure, but the engine forces an eventual shutdown. At this time the tank level sensor is not a replaceable item, the whole DEF Head must be replaced at close to $1000. and now there is a national supply shortage of the unit.
