Front Driver Side Air Bag Inflator problems of the 2012 Mercedes Benz E350

Takata recall. I was issued a takata recall for defective airbags December 2017 stating that "the defect in your driver, passenger, or both driver and passenger frontal airbag inflators may cause the airbag to explode during airbag deployment and could result in metal fragments striking the front occupants, possibly causing serious injury or death. " the recall notice states that replacement parts are expected to be available by December 31, 2018. As of today February 17, 2018, over 1 year later, the NHTSA website says "recall incomplete, remedy not yet available. " this is completely unacceptable. I bought a mercedes with the impression that mercedes stands behind its high safety rating and crash test rating. If the airbag causes serious injury or death upon deployment in a crash, then the high safety rating is irrelevant. I have been driving this car around for more than 1 year risking possible injury or death because this matter has not been resolved yet. There needs to be some recourse. Mercedes should stand behind its products and compensate its loyal clients if it cannot resolve this issue within a timely manner. In my opinion, over 1 year and counting is not considered a timely manner.
