Radiator failed on my 1999 BMW 540 at 54,700 miles. I believe this to be a safety problem that BMW needs to address. This safety problem: - disables the vehicle no matter where you are from rush hour traffic where the panic could endanger other drivers, to the middle of nowhere in the dead of winter by yourself. - steam from failed radiator blocks vision of the road, or whatever else is in the drivers side front corner of the vehicle. - failure can not be predicted by visual inspection of the radiator.
