Suspension Noise problems of the 2000 BMW 323

On my 2000 BMW 323i with about 100k miles I noticed a creaking noise coming from the rear suspension. Upon inspection, the drivers side rear differential mount has separated at the point where the mount is welded to the uni-body. This situation is very dangerous and requires immediate attention. The suspension should never separate from the body because of forces from the trans/diff. It is clear that this is a design flaw. I personally have a list of over 150 names with documented subframe cracking/failure of the e46 body years 1999-2000. The overwhelming majority of these have subframe damage at the same rear drivers side diff mount, in other words, out of four possible failure points, the rear drivers side is nearly always the failure point !! I urge the NHTSA to address this issue immediately somebody gets hurt or dies!.
