Not true, I have a 3rd gen eco diesel in my 2021 gladiator. I have 77k miles on it and its using oil, and now the intake manifold is shot. This thing has been well maintained and babied. Absolutely ridiculous we are dealing with this. Its still under warranty but trying to find a mopar certified mechanic who is capable of the job is a nightmare .
There is a reason that FCA quit making the 3.0 diesel for ANY vehicle. And it was a long history leading up to that...
The reason they stopped making the 3.0L EcoDiesel was because of the HPFP recall. They could no longer produce and sell the engines without the new part, which took over a year to be released. And at that point, they didn't have enough parts for the recall let alone to launch engine production again. I've been waiting for over two years for the recalled part and I'm still in line.
The EcoDiesel was very popular. FCA/Stellantis reported that the EcoDiesel exceeded their sales expectations. As a matter of fact, they increased production due to demand. Ram and Jeep would have kept the engine for a few more years had the HPFP not set them back.
There are lots of people who love them in both Rams and Jeeps and have had great luck personally and I was always intriqued in both vehicles. You'd hope on a gen 3 of the last iteration, they would have finally worked the bugs out of them so I hope this at the end buyers have good luck.
We have a few Gen 3 engines on the Ram forum now with over 200,000 miles. So far, they seem to be holding up well.
The Gen 2 engine (2014 - 2019) was hit and miss due to quality control. VM Motori had never built engines for mass production, so they relied heavily on robots. It appears that the wrong sized bearings were put in some of the engines, which led to a high bottom-end failure rate. So, you either got a good engine or a bad engine. Most bad engines were replaced under the 5 year/100,000 mile warranty.
Good info, I did see a couple of real good deals on the 3.0's that still were tempting there on 23's. It looks like they may have worked most of the bugs out by gen 3. AND those are Rams so the 3.0 is already toting an extra ton around before it even starts up...
It's the same reason as why they dropped the Hemi too. Meeting the new emissions and CAFE numbers.
We bought our 2023 Gladiator back in March for $15,000 off MSRP.
The Gen 2 and Gen 3 are both pretty solid considering it's a light duty engine with a B10 life of 150,000 miles. Emissions is the biggest issue. As you can see, I've had to replace the EGR cooler, DEF pump, and NOx sensors. Considering how much towing I do with the truck, I can't complain.
