Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 Galant 3.8L.

Body PASSENGER CAREngine 3.8LTransmission Automatic (S4)

The 2004 Mitsubishi Galant is a passenger car powered by a 3.8L engine paired with an automatic (S4) transmission, delivering EPA fuel economy of 17 city, 25 highway, and 19 combined mpg. Its 4.5-quart oil capacity calls for 10W-30 or 5W-30 viscosity per API standards. With 61 total owner complaints and one recall, the model year’s top issue area is Structure, placing it in the middle of the Galant’s 1990–2012 complaint history—far below the 1994 peak of 263 complaints but well above the 2011 low of three, indicating a period of moderate but notable structural concerns.

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 at 105,000 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.

Compared with the 1999–2003 model years that averaged triple-digit complaints and multiple annual recalls, the 2004 Mitsubishi Galant marks a sharp inflection point: federal complaints dropped to 61 from 139 in 2003, recalls fell to one, and investigations dropped to zero. Across the 2004–2012 generation, the trend is decisively downward, with complaints falling from 61 in 2004 to 26 in 2005 and generally remaining in the single digits or low twenties thereafter, while recalls stayed minimal. That trajectory places 2004 at the front edge of a much cleaner reliability arc, though technical service bulletins did tick up to 94 from 71 in 2003 before receding in subsequent years. The data lists top complaint areas as Structure, Air Bags, Visibility, and Service Brakes, with five crash-related complaints and zero fire complaints, but it does not specify root causes. Given its substantially lower complaint and recall volume relative to the preceding generation and its position at the start of a sustained low-trouble period, 2004 represents a comparatively sound year to buy.
