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 2010 Subaru Forester sits at the peak of its generation's complaint curve, logging 262 federal complaints — more than five times the 50 reported for 2008 and nearly double the 147 logged in 2011, with the count then declining steadily through 2013. Recall activity is similarly elevated, with 17 campaigns tied to 2010 alone, mirroring the 18 issued for 2009 and forming the high end of a generation-long recall surge (12–18 per year across 2009–2013) that is sharply out of step with the 0–2 recalls seen in most years before 2006. The dominant complaint categories — Seats (73), Air Bags (38), Engine (21), and Service Brakes (18) — and the 21 crash and 6 fire complaints point to occupant-safety and restraint issues, though the underlying root cause is not specified in the data and likely overlaps with the industry-wide Takata airbag inflator problem of that era. TSB volume also climbs through this window, reaching 229 in 2010 and peaking at 379 in 2012, signaling that Subaru was actively issuing service guidance even as complaint counts receded. Taken together, the 2010 model year lands at the worst intersection of complaints, recalls, and TSBs in this generation, and a used buyer should treat it as a higher-risk choice that warrants a thorough pre-purchase inspection and verification that all 17 recalls have been completed — the 2007 or 2008 model years offer a markedly cleaner federal record for buyers willing to accept older vehicles.
