Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1984 Colt.
The 1984 Plymouth Colt carries a modest 3-quart oil capacity with filter and accepts a range of viscosities—5W-30, 10W-30, or 15W-40—pointing to a simple, broadly serviceable powertrain. Reliability data for this model year is remarkably clean: a single owner complaint on record, focused in the Power Train area, and zero recalls. When placed against the model's broader complaint history from 1990–1994, where complaints ranged from a low of 8 in 1991 to a high of 77 in 1993, the 1984 Colt sits at the quietest end of the spectrum, suggesting an early, well-sorted iteration of the platform before powertrain concerns escalated in later years.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 1984 Plymouth Colt exhibits an exceptionally quiet federal record, with only a single power train complaint and zero crash or fire incidents documented for that specific model year. When contextualized within the broader generational data from 1990 to 1994, the vehicle sits well before a distinct upward trend in owner dissatisfaction and federal scrutiny, where complaints escalated from 8 in 1991 to a massive spike of 77 in 1993. The 1984 model's position at the very beginning of this documented arc implies it avoided the later, more severe issues that plagued the generation's end, though the data does not specify the root cause of its lone power train complaint. Because it entirely avoids the escalating recall and complaint volumes seen in the later years, the 1984 model represents a statistically safer and more reliable purchase within this generation.
