2008 GMC Acadia brakes problems

Tl* the contact owned a 2008 GMC acadia. While driving at approximately 55 MPH, the brake pedal was depressed and failed to respond. As a result, the contact's vehicle crashed into another vehicle. The contact sustained knee and head injuries and the passenger sustained unknown injuries that needed medical attention. In addition, the driver in the other vehicle sustained unknown injuries that also needed medical attention. A police report was filed. The vehicle was destroyed.

My vehicle began giving a stabilitrak notification. I took the vehicle in to identify the issue I was told by the GM service department that the master cylinder was leaking into the booster and would eventually cause the brakes to fail. Upon further research I have found several individuals who have dealt with the same issue. This is obviously a factory issue that is eventually going to cause injury or possibly fatality.
