Failure Date: 10/10/2005

I was driving on mechanicsville road at 45 mph as is the speed limit there. The car lurched to a stopped. The emergency message read, "major brake failure, go immediately to the dealer. The service manager said he had one such incident with a gentleman earlier, and it was a break in the gasket leaking oil onto the brake sensor soaking it with oil that lead to this failure. It turns out that is what exactly lead to my brake failure. The gasket broke and leaked oil onto the break sensor causing the breaks to fail.
