Brake Disc Pads problems of the 2009 Hyundai Genesis

Sudden loss of pressure in the brake pads while driving . Soft brake pads . Intermittent. City.

Brakes went to the floor, upon trying to stop for a traffic light. . . . . Pumped brakes over and over, still no resistance in the brake pedal. Began to prepare to downshift the a/t and start evasive maneuvers so I didn't jeopardize other near by drivers (and myself). As I prepared myself for an accident, the brake pedal become "spongy" and after pumping it a couple more times. . . . It finally began to work. I was beside myself! as a retired MD state trooper, I knew how to stop the vehicle; however I couldn't believe the car I loved was failing me! at the next intersection, I pulled over, allowed the car to cool down and check fluid levels (everything was within normal limits) and there were no visible leaks under the vehicle or on the ground. On 10-18-2013. . . . My vehicle was taken to Hyundai and Hyundai replaced my brake fluid, even though it wasn't necessary I had the front brake pads replaced, and the 60k mile service completed. At this time, there was no recall on this Hyundai brake issue. It is now June 2014 (mileage is now 74k) and my brake pedal is becoming spongy again and my stopping distance is becoming longer. . . . . . . . I'm afraid my brakes are going to fail me again!!! I hope that doesn't happen with the children on board! I have maintained this vehicle meticulously and serviced it at every Hyundai required interval. This vehicle has never been involved in an accident and has been garage kept. I'm very disappointed that this brake issue has seriously depreciated the value of my 2009 Hyundai Genesis!.

Had to apply brakes suddenly, car stopped as normal/expected. After this instance, the brake pedal has been exceptionally soft, often traveling all the way to the floor prior to any stopping power. The fluid level is normal, brake pads are good.
