2019 Ram 3500 — 6.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 3500 6.4L.

Engine 6.4L

The 2019 Ram 3500 6.4L is built on the D2 platform and powered by a 6.4L engine, with field data recording 134 owner complaints, 14 recalls, and the Fuel System, Diesel category as the top complaint area. Within the full 2007–2026 model complaint history, the 2019 total sits well below the 777-complaint high-water mark of 2018. At the same time, it remains far above the range’s low of 3 complaints logged for 2009. That placement marks 2019 as a comparatively moderate year in the series’ documented reliability record, removed from both the highest- and lowest-complaint extremes.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 8,000 mi; coolant every 8,000 mi. The big-interval services (every 8,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2019 Ram 3500 sits in a notable transition within its generation’s federal record. Complaints spiked sharply in 2018 (777) before dropping to 134 in 2019, suggesting either a mid-cycle refinement or a lag in reporting, while recalls remained elevated (14) compared to the 2020–2021 average (10). The data doesn’t specify root causes, but the top complaint areas—diesel fuel systems (24) and powertrain (13)—align with trends from 2017–2018, implying lingering but mitigated issues. Crash (10) and fire (5) complaints are present but not disproportionate for a heavy-duty truck. With TSBs peaking at 796, the 2019 model reflects a year of active technical service support rather than systemic failure. **Takeaway:** This is a comparatively stable year to buy, provided diesel fuel system and powertrain components are verified as updated or serviced.
