Side/window Air Bag problems of the 2009 Mercedes Benz ML350

Takata recall. Received letter from dealer to say that they now have information as to the recall of the driver side airbag but haven't heard anything since. Its been nearly a year. I called dealer who says that its just that the bag inflates too fast and is not a big deal, but he is wrong about the defect. The defect is that the bag produces shrapnel when inflated that can and has caused deaths of drivers.
