Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2008 Outback 3.0L.

Body SUVEngine 3.0LTransmission Automatic (S5)

The 2008 Subaru Outback 3.0L is a five-seat SUV pairing its namesake 3.0L six with a five-speed automatic and returning EPA figures of 17 city, 24 highway, and 20 combined mpg, with routine service calling for six quarts of 5W-30 API oil. Across the model's complaint history spanning 1995 through 2026, this model year's 230 owner complaints—concentrated in the Air Bags category and accompanied by nine recalls—place it well below the 2019 peak of 1,029 and nearer to the low end of the spectrum, suggesting a relatively quieter chapter in the Outback's reliability record despite the recall footprint.

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 Subaru Outback sits in an awkward position within its generation's federal record, representing a sharp spike in complaints (230) compared to the preceding 2007 model year (129) and the subsequent 2009 model year (111). Although 2008 sits near the end of its generation just prior to a massive complaint surge starting in 2010 (359), it still acts as a localized anomaly with 9 recalls and 198 TSBs compared to its immediate neighbors. The data indicates that airbags are the dominant concern for this specific year, driving 87 of the total complaints, with service brakes (27) and electrical systems trailing significantly. The data does not specify the root cause of these airbag failures, though the year also recorded 12 crash and 3 fire complaints. Given the elevated complaint volume and the concentrated airbag issues, the 2008 model is a questionable buy compared to the cleaner 2009 model year, and any potential purchase should be contingent on thoroughly verifying the airbag and braking systems.
