Automatic Transmission problems of the 2011 BMW X5

I own a 2011 BMW X5 35i premium. I find it unexcuseable to have brake dust continually ruining my wheels, which dealer states there is no resolution. This car is jerky when starting and driving around town. Also, cars engine roars loudly upon starting. . . . . Somethiing is not right! very hard ride, gives me headaches on freeways needing repairs. I never get headaches. Brake assist comes on in level areas or car is being held back from full acceleration. My exaust system is completely rusted, car is only 6 mo old. Warning: black dash causes drivers face to burn in hot temps. In summer. On trip I had to cover my dash with white paper towels to alleviate my face burning while driving. Leather seems inferior and indents easily and stays indented. Car does not give option on heated seats of using back or seat heat. Also does not have cooled seats. When requesting upgrade of navigation from dealer, they wanted to charge me $200. Even tho. I should have a free upgrade, since the car came with 2010 version! rear tailgate doesn't always open with key faub. Carpet round velcrow from floor came lose and tore leather on my console! with a brand new car, I did not expect so many problems! I am looking for a car without problems and expected my BMW to be just that. I am very disappointed. I all ready had to replace the windshield. Find using cruise control behind steering wheel very dangerous because it is too low and if you look down at your knees to put it on, you can't see where you are driving! my mechanic also told me there is a certain way to put on the emergency brake so the bolt into the transmission/engine? doesn't break off! ths is a car for a mechanic to own. Please advise what to do? it seems the small engine is not paired correctly with the transmission and the turbo, causing jerking when accelerating, and feels like the brake is on when you are driving at low speeds around town. This car has me very worried!!!.
