Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1978 D100.
The 1978 Dodge D100 is documented as having generated only a single owner complaint, a figure that underscores its relative durability among its contemporaries. That lone grievance centered on the electrical system, and the model year was subject to five separate recalls, reflecting a focused but limited scope of service actions. Positioned toward the more reliable end of the D series timeline, the 1978 D100’s modest complaint record suggests that, for researchers, it represents a baseline of dependable performance within the generation’s overall reliability narrative.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 1978 Dodge D100 shows only one recorded complaint, an electrical system issue, with no associated crash or fire incidents. In the broader context of the available federal record, the 1990 model year had zero complaints but one recall and one investigation, while 1992 had one complaint and one investigation, indicating that later years saw some regulatory attention despite minimal owner-reported problems. The 1978 model year predates these recorded actions and has no recalls or investigations in the dataset, though the data does not specify whether this reflects a genuine lack of issues or simply a gap in reporting for earlier years. The single electrical complaint suggests an isolated concern rather than a widespread defect. Based on this limited record, the 1978 D100 appears to be a relatively uneventful year, but a thorough inspection of the electrical system is advisable before purchase.
