Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1984 Tredia 2.0L.
The 1984 Mitsubishi Tredia was a compact sedan powered by a 2.0L four-cylinder engine paired with a 3-speed automatic transmission, with oil capacity requiring 3.7 quarts of 20W-20, 20W-40, or 20W-50 viscosity, and EPA fuel economy ratings of 22 city, 25 highway, and 23 combined mpg. This model year falls early in the Tredia's production run, and with zero recalls and just two total owner complaints—predominantly in the Engine & Engine Cooling category—the 1984 Tredia demonstrates notably strong early reliability, establishing a baseline that subsequent years would be measured against for the nameplate's durability reputation.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1984 Mitsubishi Tredia dominate in one area — the engine & engine cooling, 1 of 2 reports (50%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the engine & engine cooling 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.
