They discontinued the Eco-Diesel because they have problems with the bottom end blowing up. So much so that the Eco-Diesel was completely re-designed THREE times in its entire life span or roughly 10 years but that never fixed the problem. FCA has been losing money hand over fist replacing them under warranty, which was $18,000 Canadian when I had mine replaced in 2021. Thats just for the engine, not including labor. Had to wait months for them to even get a replacement since they are so far back ordered because of the warranty claims. My 2018 Ram was 6,000KM out of warranty when it blew up. FCA only paid for half of my engine, even though I had brought it in during my warranty period due to a low oil pressure warning, at which time I should have listened to my gut and sold the truck... I loved my Ram, the diesel was awesome. I would still have it today. Of all the dealers I spoke too, they usually had AT LEAST one Eco-diesel blown up in their shop all the time.
I have always wanted a diesel Gladiator, like dream truck like wanted... But with the experience I had with my Ram, I opted for the 3.6L JTR.
