2008 Mitsubishi Eclipse — 3.8L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2008 Eclipse 3.8L.

Body PASSENGER CAREngine 3.8LTransmission Automatic (S5)

The 2008 Mitsubishi Eclipse is a passenger car powered by a 3.8L engine paired with a five-speed automatic transmission, returning EPA economy of 17 city, 25 highway, and 20 combined mpg and requiring 4.5 quarts of 10W-30 or 5W-20 API oil. Its 71 owner complaints—concentrated in the service brakes area and accompanied by one recall—place it well below the model's 1995 peak of 392 complaints but far above the 2011 low of a single complaint across the Eclipse's 1990–2012 complaint history. For researchers, that positions the 2008 model year in the later, quieter phase of the platform's reliability arc, where the primary concern is brake service rather than the higher complaint volumes that defined the mid-1990s generation.

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 2008 Mitsubishi Eclipse sits on the downward slope of its generation's complaint arc, marking an improvement over the 2006 and 2007 launch years, which saw 99 and 107 complaints respectively following the prior generation's 2005 low of just 6. For the 2008 model specifically, federal complaints dropped to 71 with only a single recall, suggesting the initial production bugs from the early generation years were largely resolved. However, the data specifies that braking concerns heavily dominate this year, with 46 complaints in the Service Brakes category and 7 in Service Brakes, Hydraulic, though the root causes for these issues are not specified. The model also logged 9 crash complaints and 0 fire complaints. Given its improved federal record compared to the debut years of this generation, the 2008 Eclipse represents a relatively stable and good year to buy within this model's lifecycle.
