general problems of the 1999 Mercedes Benz E430

The passenger side airbag developed cracks all around and separated from the frame. This also occurred at the right hand side of the dashboard near the speaker. I am worried that the airbag will deploy unexpectedly and will create a life safety issue. I wrote several times to the mecedes-bens headquarters and not only did they deny this massive material and workmanship defect but they refused to investigate or propose a corrective measure. I am planing to take this to the media and court. This is a $55,000 four-year-old luxury car and is not expected to have cheap and defective materials.
