Cracked belts and hoses that leak, particularly near fittings are common issues on all makes/models of vehicles. Not BMW specific.

The dead pixel problem is a well known, documented BMW issue.

Brake wear....? Well, the OEM brakes cause a lot of dust, and they do a great job stopping the car but they do wear out. 42K miles wouldn't be too unreasonable for a new set of pads. If you drive gently and brake gently you'd probably get more than that. If you replace the pads with the ceramic-based pads you'd probably get more life. Axxis or Centric both make ceramic based brake pads and are reasonable in price.

There are certainly some BMW-specific pain in the ass stuff, but nothing really that you mentioned above. I'm thinking specifically of door handles that freeze in cold winter weather and the issue with the oil seperator going at the 70-90K mile mark. I'm sure others will chime in as well.
