Would anyone consider purchasing a 2021 w/ 55K miles that in the span of 1-2 months (work completed 4 months ago) had its catalytic converter, O2 sensor, map sensor, intake manifold and throttle body assembly all replaced. I have been told by a few folks that the root issue probably hasn't been taken care of which is the egr cooler and egr valve. If those are the culprits what are the chances any of the new parts have issues sooner rather than later? Is it a ticking time bomb? Assuming whatever issues the previous owner was having may still be present or they were just sick of dealing with it and that is why they traded it in shortly after the work was completed.. I will be driving it 2-3 times a week 100 highway miles roundtrip. There will be a decent amount of 10-15 highway mile trips the rest of the week.

The way you’re going to use it is exactly what the diesels like. Does it come with a warranty? Is it a smoking good deal? It’s a risk, but I feel like I’d roll the dice on the diesel.
Any pics?

The powertrain warranty is 5 years or 100k miles, which ever comes first. With the recent repairs and zero confidence the root cause was resolved, I would pass as there are many EcoD examples out there with few to no issues.

Thanks for the response. They have it priced pretty aggressively.

I think it depends how long you plan to keep it. It is a problematic engine long term with Stellantis walking away from it. New engines currently run $20-30k with installation when the times comes, and who knows if new crate engines will continue to be built 5-10 years from now.
Great platform overall, so it is sad what Stellantis decided to pull with the Ecodiesel.

Priced a little over $5k below market value and the carfax shows a history of numerous PCM, engine, and drivability checks (complaints) over the past year and a half... sounds like a problem child that the previous owner dumped and the dealership is trying to offload. I'd pass on this one.

P02E8 intake air flow 'A' position sensor circuit low was the cause of the manifold replacement, but this DTC was also present for the DPF. DPF replacement had the above and p2002 particulate filter efficiency below threshold active.

Very little information other than that. There's a PCM update for the p02e8 TSB 08-001-22 that doesn't appear to have been performed according to the service history. Odd that they'd miss it. I'd suspect that the issue has been resolved and it's probably safe to buy. It's cheap because the eco diesel is a money pit once they start acting up. Buy maxcare if you plan on buying it.

Thanks for the info! The DPF was replaced too? Can that TSB they missed still be addressed? Where do you recommend buying maxcare?

Well I'll share my experience. That's all I can do.

I had a '20 EcoDiesel in a DT Ram and a '21 EcoDiesel in a JT Jeep. Same engine of course, but BOTH of them had to go back to the shop for expensive engine oil leaks. I ditched it and bought something else. The Jeep actually caught fire on the second owners at around 20k miles on the side of the road while towing a small utility trailer. The second owners ended up without the EcoDiesel for 3 months as it sat at a dealership waiting for parts and waiting for them to figure out how to fix it. Today that EcoDiesel is on to its third owner and it's got 80k miles on it, but it's been to the shop a LOT. I can still see it in the service records when I pull up my Jeep app.

The fact is, the EcoDiesel is typical of European engines. It's poorly engineered, poorly designed, and poorly built. It's not a question of if you'll have problems, the question is when.

The best way to have a reasonable shot at a long life for an EcoDiesel is to remove the EGR system completely along with the emissions system so that it's not breathing its own s*it and coking up all the internal parts. But, obviously that's illegal in most areas so....

I would pass. Look for a Pentastar gas engine instead.

Thanks for the feedback! Yeah my 2014 w/ the 3.6 has 102K miles on it and running strong. Knock on wood, the only issue has been the oil filter housing. Given my current driving habits the ecodiesel in theory seemed like a possible good option. It's fun to drive too boot. Maybe i just jeep chugging along on my JK.

Yup the owner dumped it.

The work was done under warranty at a local dealership. The dealership's service department seems to have a decent reputation. I am trying to see if they will provide me with redacted service records. Since they have the previous owner's personal info there are privacy law issues with just releasing them.

so many seemingly random repairs on this at its relatively short age,..

don't know what the underlying issue(s) might be, but as much as i love these things, i think i'd be scared of this one and the shop that was (trying to) take care of it unless i was prepared to be working on it.

Consider getting a 2.0t. If you leave it stock you'll easily see low-mid 20mpg highway. I have 35s on mine with a 91/93 octane tune and can still break 20mpg on flat terrain when there's no headwind. Not as much torque as the ecodiesel, but a LOT more torque than the Pentastar. I'm at around 80k miles with no issues. Even pulled a 3k+ lbs trailer 850 miles with it. Other than the excessive squat, it pulled it better than our 3.6 Gladiator does.
