2000 BMW 328IC User Comment / Complaint

I was getting a tune up for my car when my mechanic notice a crack with a hole on my rear driverside. rear driver's side sub frame/ diff. mounts was torn. many people have the same issues and have made complaints to bmw manufactures but no responsible actions have been taken by bmw. this is a clear danger to the consumer while operating their vehicle not knowing that there car can been torn apart from underneath. please help myself and many other innocent victims of this defect on their car so that it can prevent accidents and injuries from accruing.
