2014 Ram 3500 — 6.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 3500 6.4L.

Engine 6.4L

The 2014 Ram 3500 6.4L stands as a heavy-duty workhorse built on the D2 platform, pairing its robust chassis with a 6.4-liter engine that demands a 7.0-quart oil capacity with 0W-40 API-rated viscosity to maintain its durability under load. While its engineering reflects the brand’s focus on towing and payload capability, this model year registers 202 owner complaints—with steering issues emerging as the most frequent concern—and has been subject to 17 recalls, signaling a period of heightened scrutiny. Positioned in the lower third of the Ram 3500’s complaint history spanning 2007 to 2026, the 2014 variant offers a relatively stable ownership experience compared to later years like 2018, though it remains a midpoint in the model’s long-term reliability narrative.

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 2014 Ram 3500 sits squarely in an elevated-complaint zone of its generation: after the 2007–2009 prior-generation models logged a quiet 3–6 complaints and 1–2 recalls apiece, the redesigned 2013 model jumped to 114 complaints and 18 recalls, and the 2014 target year climbs further to 202 complaints, 17 recalls, and 4 NHTSA investigations — a federal footprint markedly heavier than the trucks that preceded it. Within the broader arc, 2014 is well short of the 2018 anomaly (777 complaints, 4 investigations) but is conspicuously heavier on both complaint volume and investigations than its 2015–2016 siblings (136/133 complaints, 16 recalls each), placing it near the front of a hot stretch before the model partially settles mid-cycle. The 2014 complaint mix is heavily chassis- and drivetrain-oriented — steering (23), suspension (17), power train (17), and wheels (13) — and is paired with 9 crash and 7 fire complaints, which is a non-trivial safety signal relative to the record as a whole. TSB volume (572) is the second-highest in the dataset, indicating Ram was actively issuing guidance for known issues that year. The takeaway: a used 2014 is not the worst year in the generation's record, but it is a high-complaint, high-recall, high-investigation year with meaningful crash and fire counts, so any purchase should be conditioned on verifying all 17 recalls were completed and on a thorough pre-purchase inspection of the steering, suspension, drivetrain, and wheels.
