Brakes Failed problems of the 2012 Hyundai Sonata Hybrid

When the car was started a beeping alarm sounded with a warning stating that there was a brake failure. Yellow triangle with black exclamation point also warning me not to drive. Brakes had severe grinding when trying to move. This is the second time that this has happened to the car. First time was approximately a year ago. I was originally told then that there may have been a hydraulic problem but then told that it was a bad connection somewhere. Waited approximately 15 minutes and car starts with out a problem. My fear is that the brakes will lock or fail while I'm driving on the highway.

I was driving at about 55 mph on the expressway with the cruise control engaged. Suddenly there was a loud dinning and the panel on the dash flashed "hybrid safety warning", "brake failure". The care would not accelerate. I was able to pull over onto the shoulder. The car would not go over 5 mph. I pulled off of the expressway as best I could. I then shut the engine down. I restarted the engine and the warning was gone. I took side roads home, but the warning did not return. The total failure of engine power was a very dangerous situation. I took the car in to the dealer on 4/21/14. They have not returned it to me. As of today 4/24/14.

The contact owns a 2012 Hyundai Sonata Hybrid. The contact stated that while driving 10 mph, the hybrid brake system failed warning lamp illuminated and when he attempted to engage the brakes, the pedal went all the way to the floor. The vehicle was taken to the dealer. The manufacturer was made aware of the failure but did not offer any assistance. The vehicle was not repaired. The failure and current mileage was 1,300. . . Updated 03-13-13 the dealer was able to pulled a brake booster code, but since the code was no longer active, no repairs were made.
