I don't read Consumer Reports, but I do follow various quality surveys (JD Power, etc). BMW isn't near the top of most lists. In my case, I accepted the mid-pack reliability results because other things about the car were positive (driving experience, handling, etc). Everything is a trade off in life.

I think there are likely few BMW owners who believe that BMW initial product quality is class leading. And yet at the same time, BMW sales volumes have grown fairly well.
