2014 Ram 3500 Cab — 6.4L

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

Engine 6.4L

The 2014 Ram 3500 Cab, built on the robust DD platform, pairs its heavy-duty chassis with a 6.4L engine that demands a substantial 7.0 quarts of 0W-40 API-rated oil to keep its internals running smoothly. Designed as a workhorse, this model year stands out for its capability, though its reliability record reflects a mixed legacy—with 202 owner complaints, steering issues emerging as the most persistent concern, and 17 recalls addressing various components. While not the most trouble-free iteration in the 3500’s history, the 2014 variant remains a dependable choice for those prioritizing raw strength over flawless refinement, provided owners stay vigilant with maintenance and recall adherence.

Reliability & federal safety record

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

Owner complaints about the 2014 Ram 3500 Cab top in one area — the steering, 23 of 202 reports (11%), well ahead of the next concern. That matters, because the steering are also the target of recalls 19V-021 and 18E-096 on this vehicle — so the single most useful check before buying or servicing one is confirming they were actually performed. 9 of the reports describe a crash and 7 a fire — a small share of the total, but worth weighing against the steering pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
