Excessive carbon build up on engine intake ports at 35k miles. Car purchased new, has oil changes by dealer every 5k miles, and is filled with 92 octane gas. Lots of people posted on internet over last 7-8 years that Minis are prone to this issue and BMW hasn't resolved it. When asked if this should be routine maintenance, if this was driving or fuel issues, dealer said none of the above. Yet resolving this issue is about a $600-1000k repair! this either needs to be a routine maintenance, recall or service bulletin put out to owners/dealers. BMW needs to own up to this issue.
I took my 2015 Mini in for its last service before converting my lease into a financing deal and purchasing car. I was informed there was an engine recall due to crankshaft bearing problem. They have know about this issue for 2 years yet never informed me. My dealer says they have done hundreds of engine replacements. Why is this not public? I think bmwusa is hiding this from the public! while its nice they replace the engine, this is going to effect my resale value.

My 2015 Mini Cooper 4 door hardtop was parked in my garage. I started it but had not put it into gear yet. I opened the door and got out (car didn't budge) and as I walked back towards the rear, the car lurched out of park and reversed which caused it to pin me in between the car and the garage beam as it continued to roll quickly backwards as if someone was accelerating. When contacting Mini, they had one of their inspectors come (no documentation provided to me). I was called (again no documentation) and told that the engineer found no fault in the transmission or electrical system and that this was not a defect. They have since been unresponsive with providing documentation, haven't been ale to acquire parts to fix my damaged vehicle and refuse to acknowledge that there is something wrong with selling a car that can kill people and to not have parts for 4 months! I had my car for a total of 2 months total drive time. It's been in the shop for 4 months with no resolution in sight.
