@John in the Woods has over 100,000 miles on his Jeep Gladiator, Like I said, not everyone has issues. Check out the High Mileage Thread: (6) 50,000 - 500,000 Mile Club (EcoDiesel only) | Jeep Gladiator (JT) News, Forum, Community - JeepGladiatorForum.com
No you are correct but enough people have had major issues. My warranty claims now total more than I paid for the Jeep new. BTW Jeep doesn't care never had any luck with them before and even less this time

Took my jeep to the dealer for oil change, fuel filter blah blah blah, but I mentioned the hot temps and aerate towing a 4000lb airstream . They said they needed my trailer and drive up the hill I noticed the aerate to further diagnose … I told them to escalate because this issue needs to be addressed. Somehow.

perhaps they did fix it by removing the ecodiesel :-/ …

but I’m not going to leave my truck and airstream at the dealer and let them drive up to the mountains to replicate the derate… ridiculous. And they were serious too…

I think not much can be done without probably voiding your warranty and I seriously doubt the dealer will come up with any solution for you.

Many here have had success with oil coolers, but I went with the aux water cooler route thinking if the engine scattered, they might have a more difficult time blaming my mod since it didn't tap the oil system?

That's great! So, we can agree that the EcoDiesel in the Jeeps are not a POS. Instead, every dealer that has worked on your Jeep says that because they don't know how to fix it, and that's the broader point I'm trying to make.

The only way that you can prevent a derate is to watch your oil temps and adjust your speed accordingly. If you slow down, you'll see the oil temps are much better controlled. More fuel = more heat.

Yeah, there's no reason for them to try to repeat what you already know. Without a code, they aren't going to do anything meaningful. Your Jeep is doing what it's programmed to do, which is to protect the engine when it goes to overheat protection.

Right! But how do we provide feedback to FCA that what you thought was marginal is in fact worse than marginal.

if no one complained that our fuel pumps disintegrate, then they would never issue a fix.

I know the sun has set for the ecodiesel, but it would be nice if they released a TSB to beef up the radiator, oil cooler or something else.

in my mind I have to AT LEAST, be regearing, adding the aux cooler (bulletproof diesel), weight loss tune (no more EGR exhaust gas boiling my coolant). I just have a steel bumper that I like and hate to cut up, but then again AEV front bunpers

I may tap the heat exchanger plugs for an Amsoil bypass oil filter and perhaps add some more cooling.

It would be nice if they made us a larger capacity cast aluminum oil pan with more capacity like the rams, however I get the risk involved, cast aluminum shatters, steel dents.

I looked him up, it was a transmission pan … not the engine oil pan … the tranny never gets over 202 degrees.

Unfortunately, there's nothing to report to FCA since the truck is working as tested. To meet the SAE J2807 Highway Gradeability test, the Jeep must maintain at least 40 mph over the 11.4-mile Davis Dam grade with the AC on full blast in 100*F ambient temperature.

If more Jeep EcoDiesel owners would learn to slow down, they would see that the excessive oil temperatures can be better controlled.

How do you explain those who have run their jeep EcoDiesels over 100,000 miles without issues? You've got some serious issues for sure, but it sounds likes your dealer(s) have misdiagnose your issues from the very beginning.

Did you have a CP4 failure? If so, that would send shrapnel downstream and damage your injectors.
There are not too many over 100k out there on here. There are far more posts on this forum (and the JL forum) about the EcoDiesel having DPF, CP4, SCR, turbo, or overheating issues. But the real kicker seems to be how expensive parts have become. Seems to be many posts of new engines costing $28,000-32,000, and turbo chargers over $8000. That was the real reason I recently dumped mine.

That’s SPEC, pretty much what we need to determine the pass/fail criteria.

I am assuming this is at full load weight, 6500lbs?

I’d be shocked if my jeep could tow an extra ton, my 4000lb aerodynamic airstream was struggling to keep 35mph for a little bit. I turned off the AC. But it was 105+. This was going up highway 87

The tow rating is based on trim level, gears, etc. The Jeep engineers were questioned back in 2019 on why the EcoDiesel had a lower tow rating than the 3.6L Pentastar. The spokesperson for Jeep said the lower towing rating was due to the restrictive grille opening. For reference, the same engine in the Ram has a tow capacity of up to 12,560 lbs.

Is your Jeep bone stock? Big tires, body armor, etc. also robs a lot of power and will cause the engine more stress.

I agree that there aren't many Jeep EcoDiesels with over 100,000 miles on them. There are quite a few 3rd gen Ram EcoDiesels with over 200,000 miles, and a few with over 250,000 miles. The only consistent issue that we've seen is DPF clogging and that's because the oil spec on the third gen EcoDiesel is not a low ash oil compared to the 2nd gen spec. Depending on how the Jeep is driven, most will need to either replace or clean their DPF somewhere between 100,000 - 150,000 miles.

The 2nd gen EcoDiesel has a few now with over 500,000 miles.

I have 102k and tow 2-3 days a week across the scale I’m at 12k with trailer. Never had a derate but I keep on eye on oil temps. When they hit 245 I start driving less aggressively lol and do the speed limit. Just had cp4 replaced at 99k no real issues. Very small timing cover leak, valve cover and a/c compressor was leaking at 35k miles

The deep oil pan is only for the 2014 - 2019 EcoDiesel. I have one on my 2015, which now is a 12-quart capacity.
