Alternator/generator/regulator problems of the 2003 Mercedes Benz E Class

Car purchased and always serviced at fletcher johes, newport beach, CA. . A total of 20 plus faults and 13 weeks in repair out of 12 month of ownership. . . Had asked dealer to take the car back and replace it with an alternator. Dealer wants us to trade in and purchase a new car. After paying $50,000 for a quality name, this seems like a joke. 1. Foul amonia small from a/c when car is first started. Dealer changed ventilation filter but smell continues. 2. Radio button sticks. Dealer says mb does not want to fix this. Car is warranty for another four years. 3. Convinence settings for lights and mirror keep resetting. Dealer says they found no fault code but this problem remains. 4. When going up hill the transmission upshifts and the car goes to a crawl then stalls, when accelator is pressed, the transmission downshifts to 1st gear and the car leaps forward. Dealer says they found no fault code but this problem remains.
