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 model year sits within a plateau of moderate federal activity during the middle of this generation's lifecycle, recording 43 complaints, 4 recalls, and 2 investigations—figures nearly identical to 2011 and consistent with the 2007-2012 period that followed the 2006 spike of 123 complaints but preceded the 2015 surge to 176 complaints. While technical service bulletins peak at 870 for 2012, complaint volume remains stable relative to adjacent years, with 2013 showing a notable drop to 20 complaints. The data shows 31 of 43 complaints concern air bags, with 2 fire-related and 1 crash-related complaint, though the federal record does not specify root causes for these incidents. With recall and investigation counts matching the prior year and remaining below the highs seen in 2009-2010, 2012 represents a relatively stable vintage before the significant escalation in complaints and recalls that characterize 2015 and later years. This positions 2012 as a statistically moderate year within a generally troubled generation, making it a cautiously acceptable choice compared to the problematic 2006 and 2015 model years, though buyers should verify air bag service history given the concentration of complaints in that category.
