This is funny. https://autos.yahoo.com/blogs/motoramic/tesla-tops-consumer-reports-rankings-again--but-buick--subaru-gain-174501201.html
Why? There's a lot less to go wrong on a tesla. I have actually been thinking about one for myself. For me, it would make sense. My commute is 240 km a day. 700 hp and awd! Giddy up.
I just skimmed the fine print on the press release and it looks like MINI's low score is due (at least in part) to lack of data.
On the other hand, MINI ranked third (behind the Scion tC and VW Eos) in the Compact Sporty Car category of J.D. Power's 2015 U.S. Vehicle Dependability Study, which measures customer satisfaction after three years of ownership. So, believe whichever survey suits your mood at the moment.
