06/21 build. 17k miles. No diesel related issues. No fuel additives until 16k. Now use EDT every fill up. Love the power plant but would be happier if the cp4 recall in the RAMs trickled down to the JTD. Last I heard the 6.7 was getting a cp3 conversion? Also curious for those with failures if they tow

Got majorly high centered and had to be yanked out by a dually and it took quite some jerking. Dealer says the strain may have caused it. Still covered.
Unless they were pulling on the block or the trans, I don't think that would cause a main seal to leak... ever.

Also, don't ever tell the dealer that which they may not be able to prove that they can use to deny a warranty claim.

22k and mine just came in, no issues, never drained it once. Local dealer said 30k but I want to swap it before a cross country trip we have coming up.
30k? I thought it was every 10k. I have my first one ready to go.

I've not had any issues with my motor other than a few ghost CEL's that auto cleared. I had an ABS sensor go bad, but that's not diesel related.

How often is everyone draining their fuel filter? About to hit 6k and haven't done it yet.
Well there is a water sensor at the bottom of the fuel filter housing that is supposed to warn you, but some feel that is too late and/or not 100% reliable.

Even the owners manual says if that water light comes on, IMMEDIATELY pull over and drain it.

944 miles in 7 weeks and no issues. Dealership gave me a free tank of fuel, so I have only bought about 8 gallons of fuel myself. (They bribed me for a good survey review with a 2nd tank of fuel.)

I just ordered 2 fuel filters from FactoryMoparDirect.com. $73.16 each. Think they list for $103.00

The manual says every 20,000 miles unless you live in a state with crappy fuel. (The manual names the states) Then it's every 10,000 miles.

Only towing has been a uhaul trailer for an in town move and my 20’ car trailer empty once or twice. It has been on 37s for about 3600 miles, so there’s a little more load on the engine than it would be stock. Luck of the draw, I suppose. We are rapidly approaching payment #2 FCA will be paying, and still waiting on the fuel rail.

7.6k with no issues. I put additive in every other fill up. No issues at all, knock on the diesel tank! Dont even start with the fuel pump crap...I keep my filter drained, and will change it out every other oil change, so like every 10k or so.
I’m a little touchy on the fuel pump subject after it stranded the family and I in the middle of fricking nowhere despite being overly cautious. It can happen to anyone. There’s zero warning. The motor just dies and won’t restart. Trust me, it’s a terrible feeling when you realize you’re f***ed and there is nothing you can do about it.

Because of that I was just thinking about draining it a bit every oil change just as a preemptive measure. I bought a new fuel filter when I did my first oil change just to have on stand by in case I need it.

Did you use any fuel additives? I'm assuming no since there is none reported in the poll that have used additives. That said, I've seen that the CP4 failure rate is as high as 8% in the US vs just 1% in the EU due to our diesel being dry and the poll is now indicating a failure rate of less than 3% (although a bigger sample size is would be helpful). If I had to guess being a smaller engine the CP4 doesn't have to push the same volume of fuel which might help it in our case.

Curious, where did you see that 8% reference?

I read that too. Can't remember where tho. Think it was in one of the articles on the CP4 to CP3 conversion.

No, and frankly, I shouldn't have to. My 2012 and 2016 Powerstrokes pumped way more fuel at 9k than this EcoDiesel has and I had zero issues with them and I didn't use fuel additives in them. Ultimately, the failure is on the manufacturer. I shouldn't have to add anything to my tank except fuel. Bosch failed to design, or update the design for, a component that would stand up to what would be considered "normal use". I didn't over task the fuel system and ask it do do something beyond design parameters. In fact, I would say that I've never even had it close to the system design parameters. I get that there is less lubricity in the fuel in the United States, but that's not an excuse for component failure. ULSD has been around since 2010. That means that Bosch had 11 years before my vehicle was built to design a fuel pump that would work reliably pumping diesel fuel with sulfur levels less than or equal to 15 ppm. FCA bears responsibility was well, CP4 failures were a known issue well before the EcoDiesel was installed in my vehicle. Hell, I knew CP4 failures were fairly common, so much so that I've added riders to my insurance policies for all four of the diesel powered vehicles I've owned since 2012. I read the horror stories of the guys getting stuck with a $12k bill because Ford wouldn't honor the warranty. I even read the horror stories about the folks having warranty claims denied because they used fuel additives driving me to not use additives. I did, and will continue, to go above and beyond with draining the fuel/water separator at 2k miles intervals, made sure I bought at high turnover stations, and would have (had the fuel pump not grenaded) changed the fuel filter at 10k miles. The above got the 2012 Powerstroke to 65k miles with no significant fuel system issues (failed fuel pressure regulating valve with 3500 miles on the truck, covered under warranty) when traded in, the 2016 to 27k miles with no fuel system issues when traded in, and a 2015 EcoDiesel Grand Cherokee to 75k miles with no fuel system issues when traded in. I didn't use a single ounce of fuel additive in any of those. I towed heavy with both of the Fords. Think 44 foot, tri axle toyhauler with toys in it heavy.

So, no, out of fear of having a warranty claim denied, I didn't use fuel additives. Now, that being said, you damn well better believe that going forward it's going to have additives in the tank. It does infuriate me when I get asked if I added fuel conditioners/additives, though. It infers that I should have and was stupid for not using them. I didn't do anything wrong by not using them, in fact the owners manual states "commercially available fuel additives are not necessary for the proper operation of your diesel engine." (Yeah, I can read and follow a manual.) I'm a pretty smart guy. I have operated and maintained nuclear power plants for the US Navy for the last 20 years. If a technical manual, or in this case the owners manual, tells me something isn't necessary, I'm not going to do it. In fact, I'm not even going to consider doing it because I assume the engineer that designed the system knew what he or she was doing and if I needed to do it the manual would have told me to. I'm going to assume that additives will cause adverse effects.
