Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1977 W300.
The 1977 Dodge W300 appears in the record as a model-year reference point, and the reliability data attached to it are sparse. Only one owner complaint has been filed, with Steering standing as the top complaint area, while a single recall covers the year. Taken together, those figures give the 1977 W300 a very light documented-reliability footprint, so any conclusion about its durability should be read as tentative and shaped by the small sample size rather than by a broad pattern of failure.
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 1977 Dodge W300 dominate in one area — the steering, 1 of 1 reports (100%), well ahead of the next concern. None of this vehicle's 1 recall campaigns target the steering, 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 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.
