Latest Anthem engine complaints
Having heard rumors for some time of the dreaded DEF shut down while using our motorcoach, without a recall of the unit , we have to assume the coach is safe to use. Ours had been parked in the storage building for about 10 days. Yesterday I went to get it out.When I started the coach it immediately turned on the check engine warning. It threw 3 codes, SPN#3374, SPN#3031, & SPN#1761. I'm told the engine will derate first by 25%, next it debates by 40%, then finally to limp mode of 5 mile per hour. If this had...

happened the week before I would have had a wife and two dogs, in 95 degree weather with no engine, no air conditioning and about 250 miles from home. When I contacted the manufacturer I was told Parts might be available mid August to September. Fortunately I was at home. There are any number of people being left at the side of the road waiting on a tow truck. We are using what is considered a Gen 6, or a Generation #6, the replacement is to be a Gen7, which seems to have a better reliability but is currently unavailable. The codes have been emailed to the manufacturer and they have had enough experience that they know what the problem is.
The DEF head sensor failed giving a warning that the engine would be derated if the engine was not shut off. The safety hazard with a derated engine is that 5 mph is top speed, not only endangering my vehicle, plus other vehicles near by. The head sensor was replaced by Cummins after purchasing a replacement tank with a new head sensor attached. The purchase was made from Spartan, the manufacturer of the Chasis. Individual head sensors were not available due to a nationwide shortage. I was first made aware of a...

problem when a DEF warning buzzard and a check engine light started while driving down the interstate. I checked the DEF tank and found it to be 3/4 full and no leaks or noticeable problems. After Cummins replaced the tank with a new head sensor I was able to drive 2000 miles without another problem.
DEF failure 7/28/2020. Can not drive Vehicle. Goes into slow mode There are warning lights and messages that state do not drive.
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 45 ft motor coach is a very large truck in which I pay ridiculous license fees to keep it on the road. This DEF head supplier has got to be held to the same reliability standards as the auto industry. If not then you should demand a recall on these units at Shaw Industries cost for replacement or reimbursement to owners who spent upwards of $1000+ to fix this issue. Please address this issue so diesel vehicle owners can enjoy the same protections we do for our gas vehicles. Thank you , Mike Arnold
DEF head failure in June 2021. 100 miles after Leaving Clemson, SC, check engine light came on and DEF head indicator turned orange. DEF tank was over 1/2 full. Talked to Spartan rep in the afternoon he said keep driving until you get 3 fault codes. Got parked that evening in Nancy, KY and had 5 error codes. Fortunately we were in a safe parking lot and not on the highway. Saturday morning Coach started but wouldn't go. Replacement was mailed from Spartan Monday to mobile repair unit in Kentucky. DEF head...

was replaced Wednesday AM and we were back on road by 10am. The DEF head failure seems to be an epidemic on Spartan RV chassis (and other vehicles). We had about 24,000 miles on engine and many of our RV friends had similar failure experiences.
While driving from Los Angeles to Phoenix on 03/07/2019, I received a series of check engine lights and warnings. These came and went , then eventually stayed on. When I got to the dealer in Phoenix, they sent me to an engine/chassis repair facility. The red stop engine light came on (with full derate to 5 mph) just as I pulled into the facility lot. (Whew!) The problem was a defective DEF head (codes 6255 derate 17 counts, 3868 def quality 59 counts, 4677 fluid level uprate 69 counts, 4572 temp uprate 69 counts). ...

The shop had a new head overnighted from Spartan (took 3 days, actually) and repaired under warranty. I am reporting this because these heads are breaking in large numbers now, with a mandatory derate, and if it happens somewhere other than in a shop lot, Bad Things can happen. I understand that there is an investigation going on into this because of numerous failures. I am unwilling to take a long trip across the desert now because I might get stranded.
DEF Fluid Sensor failure codes displayed and warnings of impending engine delayed or shutdown. Cold not continue driving. My safety concern is my vehicle can be stranded on a roadside which my not be possible for a 45 Foot Motorhome. Many RV's are having this issue and the Manufacture of this unit SHAW Industry can not supply any parts. Leaving many stranded!
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.
The DEF sensor head failed leaving my 45 foot RV stranded on the side of the interstate with my wife and kids inside.
Vehicle was stationary. After starting once to fill air pressure, turned off and 1/2 hour later turned key to on and the check engine light stayed on. Three error codes all relating to def were displayed. Spartan sent out a new def head and it was replaced. The next week after about 800 miles of driving and several stops and starts one of those three codes is now displaying. Waiting for cummins to diagnose the current issue. The def issue can lead to derating at any time, which I have not had explained to me quantitatively. This poses a considerable safety hazard if running at 65 mph on a crowded interstate and the coach slows down to 5 mph.
Radiator has been replaced three times. 58,000 Miles on the rv. Seems to develop leaks over a period of time. Just not made well.
