Abs Brake Fail problems of the 2008 BMW 335

Abs system failure light came on after 20000 miles. Dealership told me that it would cost $4800 to fix but that BMW was aware of the problems that people were having and typically offered a break on the cost of the parts as a "goodwill" gesture. This so called "goodwill" was not offered to us and were advised that the car could be driven without the repairs as long as we realized that we "were driving a car from the '70s". How can you garage keep a $52000 car and have such a system/safety breakdown after 20,000 miles. In addition, how can a manufacturer recognize this failure in the form of "goodwill" gestures until they tire of doing so? I would ask the NHTSA to please encourage the manufacturer of this vehicle (BMW) to fix this fault in their production/design at their cost. Thank you.

Abs unit failed, all warning lights on. Per mech. Common prob, BMW even sells repair kit so common. Very expensive fix, I am sure people driving without abs/traction control. Very unsafe BMW from 2006-2009.
