No warning symbols on the dash. Taken to dealership after several weeks of communication saying this was a safety issue and received a loaner vehicle. However, they have said if THEY cannot reproduce the issue, we will just ge…

While driving vehicle, multiple warning codes appeared including: service traction control, ABS, service brake system and others. More importantly, the power brakes failed and a code was thrown to press hard on brakes to stop vehicle.

We had complete brake system failure while driving the car on the highway. The brakes went all the way to the floor when applied and we came inches going into fast moving oncoming traffic before the vehicle stopped.

I purchased the vehicle, and twelve days later while operating the vehicle I experienced full braking power failure. My foot was to the floor board while trying to get the car to slow down. Up until the point of brake failure, there were no warning lights or "symptoms" that would alert me as to an impending problem. My young child was also in the car so that was extremely scary also. During this t…
