2012 BMW 3 Series: True Cost, Problems & Verdict
177 NHTSA owner complaints · 7 recalls · data-computed verdict. No opinions — public data only.
Editor's note
Avoid the 2011 3 Series, which has 994 owner complaints and a score of 31, and the 2014 car, with 555 complaints and a score of 36. Buy the 2013 car, 74 complaints and a score of 87, or the 2012 at 78 on 177. Read the full note on the model page. 2012 specifically: a year the record favours — 177 complaints, score 78/100. The caveats in the note apply to other years of this nameplate more than to this one.
