That is sad. I don’t know why you are having so many problems as my Countryman (Classic with Level2) has behaved well since new. Took me a while to sort out all the gizmos but once done everything worked as expected. Before I got the car I read about problems with A/C, lights, voice activation etc. so was quite apprehensive, however, I haven’t had any real problems with anything at all - if you disregard some idiot denting the passenger door while parked. That cost me £150 but ‘Dents’ repair completely removed the dent back to new.
Have you downloaded the latest software update? It seems to make the display transitions quicker and smoother and I noticed this morning that the Auto A/C was even more reactive in warming the cabin. I am sure there are a number of other items it will have updated, maybe not visible to me but maybe will resolve some of your problems - worth trying anyway. Downloading update is dead easy, download to your smartphone via the MINI App and then next time you drive the car it will get uploaded to the car automatically. Then all you have to do when you have parked the car and won’t be driving for 20+ minutes is Activate the update via your Smartphone MINI App. After update has been activated worth going through the options to check those you want are activated. e.g. it switched off the Assisted Driving view in the HUD so just had to reactivate.
Give it a try - otherwise get your Dealer to sort out your problems.
