2008 Dodge RAM 1500, 2500 Pickup — 6.7L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2008 RAM 1500, 2500 Pickup 6.7L.

Body TRUCKEngine 6.7LTransmission Automatic 4-spd

The 2008 Dodge RAM 1500/2500 pickup sits on the DH chassis and is powered by a 6.7‑liter engine paired with a four‑speed automatic transmission, delivering a modest EPA rating of 14 mpg city, 19 mpg highway and 16 mpg combined while requiring a 6‑quart oil change with 5W‑30 API oil. Its robust displacement and straightforward drivetrain make it a work‑horse for heavy‑duty tasks, yet the model’s reliability record is tempered by 578 owner complaints, the most frequent being air‑bag issues, and a total of 12 recalls documented for the year. This places the 2008 iteration as a generally durable platform whose mechanical fundamentals are sound, but one that demands attentive maintenance and vigilance regarding its safety‑system components.

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 2008 Dodge RAM 1500, 2500 Pickup lead in one area — the air bags, 142 of 578 reports (25%), well ahead of the next concern. That matters, because the air bags are also the target of recalls 15V-313 and 16V-352 on this vehicle — so the single most useful check before buying or servicing one is confirming they were actually performed. 44 of the reports describe a crash and 7 a fire — a small share of the total, but worth weighing against the air bags 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.
