The computer component surged, and the vehicle is available for inspection. The vehicle brake function is lost. Stepping on the brake paddle did not apply brake. Brake function was disabled by the computer. I took the vehicle to dealer, they said it was a component that has high resistance that cause it. But not sure why it has high resistance at that time and the resistance is gone after driver restarted the vehicle. No one else inspected the component beside the dealership. There was no warning at all and this is the first time it happens. Driver was just driving normally and suddenly all the light in the instructment panel started blinking and driver tried to apply brake but nothing happen. Luckly it wasn't rush hour, and driver was able to let the vehicle roll to the freeway exit on ram and use the up ram to slow the vehicle until it almost stop and changed gear to Park to stop the vehicle. Driver then restarted the vehicle and the problem is gone.

In traffic, approx. 10-15 MPH car in front stopped short. I put foot on the brake pedal and pushed the brakes pedal to the floor. The car did apply the brakes equally as hard as I was Appling brakes at the pedal

I was driving on the freeway about 65 mph on Saturday June 18. In a sudden instant, there was a message on my dash "brake module failure" and "speed limited to 62 mph". Also warning message that "forward collision warning was off", etc. The ABS light, the "check brakes light", and the check engine light all were on. Also, the power brakes went completely out and to stop I had to press really hard with manual brakes. I don't think a small framed person would have been able to stop and if I had been at a moment where I needed to stop quickly I don't think I would have been able to stop had there been a need to stop quickly. The dealer tells me that the brake master cylinder failed. The car has 43,000 miles and has been well maintained.

While driving, I received a notice identifying a problem with the ESC system and that there was a brake system failure. I have received an advanced diagnostics alert about the antilock braking system. the vehicle was difficult to stop and required excessive pressure on the brake pedal.
