1986 Mitsubishi Galant — 2.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1986 Galant 2.4L.

Engine 2.4LTransmission Automatic 4-spd

The 1986 Mitsubishi Galant 2.4L pairs its namesake engine with a 4-speed automatic transmission to deliver an EPA-estimated 18 city and 24 highway mpg, utilizing 3.7 quarts of oil in viscosities ranging from 20W-20 to 20W-50. With only 4 total owner complaints—predominantly focused on the seat belts—and just 2 recalls, this specific iteration demonstrates a notably trouble-free record for its era. Contextualized within the broader 1990–2012 model complaint history, which peaked at 263 complaints in 1994 and hit a low of 3 in 2011, the 1986 model's minimal issues mean it stands as an exceptionally stable early chapter in the Galant's reliability lineage.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 30,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

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 1986 Mitsubishi Galant sits at the very beginning of the generation covered by the federal record, which starts in 1990 and shows a clear arc: low complaint and recall counts in the early 1990s (e.g., 24 complaints and 1 recall in 1990), a sharp spike in 1994–1995 (263 and 249 complaints, respectively), and another peak around 1999–2001 (237 complaints in 1999, 167 in 2001). For the 1986 model year specifically, the data reports only 3 seat belt complaints and 1 each for steering, service brakes, and visibility, with 1 crash complaint and no fires—figures far below the later-year averages. This places the 1986 model in the low-complaint early phase of the generation, before the major issues that drove the 1994–1995 and 1999–2001 spikes, though the root causes of those spikes are not specified in the data. Because the record begins four years after the 1986 model’s release, some early-life problems may be missing, but the available numbers suggest it avoided the high-frequency complaint patterns of later model years. **Takeaway:** The 1986 Galant is a good year to buy, as its minimal complaint record indicates it is less prone to the systemic issues that emerged in subsequent years, provided you find a well-maintained example.
