Are you talking about the 2010 ratings by brand? Because BMW rated three stars (about average) in all categories (overall dependability, powertrain dependability, body/interior, and features/accessories).

Even Acura's overall dependability was only three stars. And Audi was three stars in three categories but only two stars in powertrain reliability. Infiniti, which often ranks very high on Consumer Reports, also rated three stars in 3 categories but 4 stars in powertrain reliability. Lexus was obviously tops in all categories.
