Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1976 D300.
The 1976 Dodge D300, a full‑size truck built on Dodge’s A‑body platform, entered service with a modest 2‑owner complaint record and two recalls, indicating a relatively clean reliability profile for the era. Its most frequently cited issue centered on tire performance, a common point of attention for heavy‑duty vehicles of that period. When compared with later model years, the 1976 D300’s low complaint volume and limited recall activity suggest a comparatively stable platform, offering researchers a benchmark of early‑stage reliability for the D300 lineage.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1976 Dodge D300 dominate in one area — the tires, 2 of 2 reports (100%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the tires, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the tires 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.
