2012 Subaru Forester

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2012 Forester.

Body SUVTransmission Automatic (S4)

The 2012 Subaru Forester is an SUV equipped with an Automatic (S4) transmission and an engine requiring 4.5 quarts of 5W-30 API oil, delivering EPA-estimated fuel economy of 21/26/23 mpg. Against the model's 1998-2026 complaint history—which spans from a 2019 peak of 831 complaints down to just 12 in 2026—this model year registers 105 total owner complaints with Engine cited as the top concern alongside 15 recalls. That positioning places the 2012 Forester well below the nameplate's highest-complaint years, indicating a vehicle that avoids the worst reliability pitfalls of the range yet still carries documented engine concerns and recall activity that researchers must weigh against its specifications.

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 2012 Subaru Forester sits in the latter, more mature phase of its generation's complaint arc, which began with the 2009 model year (178 complaints, 18 recalls) and peaked in 2010 (262 complaints, 17 recalls) before steadily declining. By 2012, complaints had fallen to 105 from 147 in 2011, and recalls ticked down from 16 to 15, continuing a year-over-year decline that extended into 2013 (77 complaints, 12 recalls). Notably, TSBs rose sharply to 379 in 2012 — the highest in the generation — suggesting Subaru had by then identified and documented a broad range of issues, equipping dealers with repair guidance rather than leaving problems unresolved. The top complaint areas for 2012 center on Engine (20 complaints), Air Bags (16), and Vehicle Speed Control (10), with 15 crash-associated complaints and 5 fire complaints, though the federal data does not specify root causes for these categories. The sharp contrast with the following 2014 model year — which saw complaints surge to 403 with only 2 recalls — reinforces that 2012 benefits from being a late-cycle product in a generation whose major issues were largely addressed. For a used buyer, 2012 represents one of the stronger years in this generation: complaint volume is moderate and trending downward, recall activity is well-documented, and the extensive TSB coverage means known issues are more likely to have been serviced.
