1999 Mitsubishi Galant — 3.0L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1999 Galant 3.0L.

Body PASSENGER CAREngine 3.0LTransmission Automatic 4-spd

The 1999 Mitsubishi Galant 3.0L is a passenger car powered by a 3.0-liter engine and a four-speed automatic transmission, EPA-rated at 17/25/20 mpg and requiring 4.5 quarts of 10W-30 or 5W-30 API oil at service. Within the 1990–2012 Galant complaint history, the 1999 model’s 237 owner complaints place it near the upper end of the range, just below the 1994 peak of 263 complaints and well above the 2011 low of 3, with Service Brakes, Hydraulic standing out as the top complaint area and nine recalls on record. That profile marks the 1999 Galant as one of the more complaint-heavy years in the model’s run, so brake-system history and recall completion should be central to any research or evaluation.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 60,000 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.

From 1990 to 1998 the Galant’s federal record shows a pattern of high complaint volumes in the mid‑1990s (peaking at 263 complaints in 1994) followed by a decline to 62 complaints in 1998. The 1999 model year breaks that downward trend, recording 237 complaints, 9 recalls and 116 technical service bulletins—levels comparable to the earlier 1994‑1996 peak and markedly above the 1998 low. Investigations remain zero in 1999, as they did from 1995 onward, indicating that the increase was not accompanied by formal NHTSA investigations. After 1999 the complaint count falls to 149 in 2000 and continues a gradual decline through the 2000s, suggesting that the 1999 spike was part of a short‑term resurgence rather than a new long‑term issue. Consequently, while the 1999 Galant is not as problematic as the worst years (1994‑1996), its complaint and recall figures are higher than the surrounding years, making it a less attractive purchase than the low‑complaint 1998 model but comparable to the earlier peak years.
