Ram & Jeep 3.0L EcoDiesel (2023+) Problems, Symptoms & Fixes

February 5, 2026

The 2023 model year marked the final production run of the 3.0L EcoDiesel V6, ending nearly a decade of use in the Ram 1500, Jeep Wrangler JL, and Jeep Grand Cherokee. While these trucks offer strong fuel economy and towing power, they still carry forward many of the issues seen in earlier generations.


At DK Auto & Diesel Service in Magnolia, TX, we help EcoDiesel owners maintain and repair their final-generation trucks for long-term reliability.
