1986 Mitsubishi Mighty Max — 2.0L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1986 Mighty Max 2.0L.

Engine 2.0L

The 1986 Mitsubishi Mighty Max 2.0L specification centers on a 2.0-liter powerplant requiring 3.7 quarts of oil across viscosity grades spanning 20W-20 to 20W-50. Owner records identify Engine & Engine Cooling and Equipment as the top complaint areas, with this model year generating seven total complaints and one recall. Against the broader 1990–1996 production window—where annual complaint volume ranged from a low of three to a high of eleven—this 1986 data point sits in the middle of the documented reliability curve, providing researchers with a moderate baseline for cross-year comparison.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The federal year-by-year record for this generation begins in 1990, four years after the 1986 target year, so direct comparison to adjacent model years is not possible from the data provided. What the record does show is a complaint arc that peaks early in the generation's documented life — 11 complaints in 1991 — and then declines steadily to just 3 by 1996, with recalls limited to 1990 and 1991 (one each) and no investigations across the entire span. TSBs, by contrast, rise sharply from 5 in 1990 to 19 in 1996, suggesting Mitsubishi's service response matured over time rather than front-loading fixes. The 1986 model sits entirely outside this documented window, meaning no recall, investigation, or TSB data exists for it in the provided record; the only available figures are six complaints spanning engine and engine cooling, equipment, seat belts, engine, and electrical system, including one fire complaint and zero crash complaints. Because the 1986 predates the earliest federal data in this set and carries a fire complaint with no corresponding recall or TSB on record, the data is too thin to call it a strong or weak year — buyers should treat it as undocumented and prioritize a pre-purchase inspection of the engine and electrical systems, where the complaints cluster.
