| 4th Gen DS (2015-2018) | 3.6L Pentastar V6 / 5.7L HEMI V8 / 3.0L EcoDiesel V6 (8HP 8-speed) | $1,100-$1,500 | 3/5 | HEMI tick: the MDS cylinder-deactivation lifters and camshaft are the subject of long-running owner complaints and class-action litigation against FCA (Petro v. FCA US LLC) - a lifter/cam job is a heads-off repair; Broken exhaust manifold bolts are a well-known HEMI pattern; RepairPal estimates the manifold gasket job at $332-$473, and it climbs when bolts snap off in the head; The 3.0L EcoDiesel of these years is bound up in the FCA emissions consent decree - verify software and warranty status on any used one | Cheapest buy-in; the 3.6L Pentastar avoids both the MDS lifter and the 16-plug tune-up |
| 5th Gen DT (2019-2024) | 3.6L Pentastar eTorque / 5.7L HEMI eTorque / 3.0L EcoDiesel (2020-2023) / 6.2L supercharged TRX | $1,200-$1,600 | 3/5 | Long recall list - among them a 2020-2023 EcoDiesel high-pressure fuel pump failure campaign (NHTSA 22V767) and a powertrain control module stall recall (23V265); all free at a dealer; The 48V eTorque mild-hybrid adds a belt-starter-generator and its own battery, warranted 8 years/100,000 miles; HEMI lifter and manifold-bolt watch items carry over; the Pentastar V6 remains the low-cost engine | The best-riding full-size truck of its era - pick the Pentastar eTorque if running cost is the priority |
| DT refresh (2025-2026) | 3.0L Hurricane twin-turbo I6 (420 hp / 540 hp RHO); 5.7L HEMI V8 returns for 2026 | Too new for reliable data | 3/5 | The Hurricane twin-turbo I6 is a new engine family with no long-term cost record yet - verify its service parts and intervals against a current dealer catalogue rather than assuming HEMI/Pentastar interchange; Boosted direct-injection engines historically run shorter plug intervals than the naturally aspirated HEMI - confirm with the owner's manual; The 5.7L HEMI returns for 2026 by customer demand, bringing its known service profile back with it | Buyers who want the newest truck - but there is no 10-year cost history for the Hurricane yet |
