Rear Suspension Coil Springs problems of the 2002 BMW 325

The rear coil springs have broken three (3) times. The car was purchased new in 2001. The springs failed at 52000 miles in 2008, at 77000 miles in 2013 and at 89000 miles in 2017. The bottom coils fractured and rusting in the area was evident. I have both broken springs from the latest incident. BMW refuses to participate in the cost to repair. BMW cost is $1100. This is a safety issue.

The contact owns a 2002 BMW 325xi. While driving approximately 45 mph, a loud clanking noise emitted from the rear end of the vehicle. The contact continued driving and the vehicle was taken to an authorized dealer for diagnostic testing. The technician detected that both rear coil springs were fractured. The vehicle was repaired. The manufacturer was not made aware of the problem. The approximate failure mileage was 50,000.
