Even change to new tires, the air pressure up to 37 and always after 1 week or so, down to 33, complain and change tire and still have the same result. You could only check the tire pressure after you run for a while. Massage chair, after operation and all the sudden it stop. Clock in the cabin doesn't change even you set it up and the internal said the right time and the front doesn't change

I was in unfamiliar area. Remote key would not operate. When using small key to enter vehicle car siren would not quit blaring and.new batteries did not help. Mercedes responder told me I had inoperative "dead" key. Car of course was inoperative. No way to move car from area. Could not secure car. I had rbm in atlanta on cell phone entire time. About hour later someone took me to my home for spare key. This worked. Key was as Mercedes responder told me...... dead. The Mercedes keys are unsafe and undependable. Need to be recalled. Mercedes would not replace "dead" key per kyrus frames at rbm in atlanta. Because my car had 57000 miles on it and out of warranty. Key must be recalled due to safety concern there is no way to operate a "dead" key. Mercedes responder told me that he sees it all the time. What if"?? I had been miles from home? unsafe area? compromising situation"this is unacceptable for $100,000 car. I could be dead. Just provide a workable key Mercedes.
