Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1976 D300.
The 1976 Dodge D300 enters the historical record with a notably quiet complaint profile, logging just two owner-reported issues across its service life with tires emerging as the sole recurring theme. That same restraint carries into its safety ledger, where only two recalls were issued — a figure that suggests either limited systemic faults or a model that largely avoided the regulatory scrutiny that plagued many contemporaries. For researchers, this sparse paper trail positions the 1976 D300 as a statistically uneventful year in the truck's reliability arc, meaning surviving examples owe their condition more to maintenance discipline than to any inherent design vulnerability.
Condensed service procedures for routine maintenance. Procedures that require dealer diagnostic equipment are identified and summarized only.

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.
