1988 Mitsubishi Mighty Max — 2.0L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1988 Mighty Max 2.0L.

Engine 2.0L

The 1988 Mitsubishi Mighty Max is a 2.0L-powered truck with a 3.7-quart engine oil capacity rated for 20W-20, 20W-40, or 20W-50 viscosity grades. Across this specific model year, owners have logged just nine total complaints, with seat belts representing the most-cited issue and a single recall on file. That figure falls within the broader 1990–1996 Mighty Max reliability record, which peaked at 11 complaints in 1991 and bottomed out at 3 by 1996. Sitting between those two extremes, the 1988 model year tracks as a mid-range entry in the lineup's complaint history, with seat belts—as a non-powertrain concern—leading the modest report count and just one recall on the books.

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 record begins in 1990, two years after the 1988 Mighty Max, showing a modest but rising complaint count (7 in 1990, 11 in 1991) before stabilizing around 9–10 through 1992 and dropping to 3 by 1996. Recalls are rare across the span, with only a single recall recorded in both 1990 and 1991 and none thereafter, while Technical Service Bulletins (TSBs) increase steadily from 5 in the early‑1990s to 19 by 1996. For the 1988 model, the only documented complaint areas are Seat Belts (7 reports), Tires (1) and Engine & Engine Cooling (1), with zero crash‑related or fire complaints, suggesting that the most frequent issues were safety‑equipment concerns rather than catastrophic failures. Because the broader generation shows low recall activity and a downward trend in complaints after the early 1990s, the 1988 Mighty Max does not appear to sit in a high‑risk period; however, the absence of direct federal data for 1988 means you should verify condition‑specific factors (e.g., seat‑belt hardware) before purchase. Overall, 1988 is a relatively safe year to consider, provided you inspect the noted belt and tire components.
