This has happened a total of 4 times since i have owned the car. the first happened a few months after purchasing the car, when trying to stop from 40mph at a red light. the brakes failed and i ran the red light avoiding any accident. i drove approximately 25 more miles with no occurrence the rest of the way home. next morning when driving into the gas station as i hit the driveway entrance approximately 15mph i was braking and then brakes went to the floor and i had to pump the brakes several times before the pressure came back and i finally stopped. i turned around drove it to the dealer with no other issues along the 8 mile drive. dealer checked all normal issues drove it themselves and were not able to find ?duplicate the complaint?. approximately 8 months later after driving 25 miles on the freeway i was exiting my exit to work slowing down at approximately 30mph while braking and slowing down the brakes went to the floor and all pressure was lost i pumped the brakes and they worked. 2 weeks ago i was driving surface streets and while slowing down to make a right at a red light at about 30mph the brakes failed i had to pump the brakes again to regain pressure and i stopped as i rounded the corner into the cross walk. i have not been able to get it into the dealer yet. i have been driving a different car and parked this one until my schedule allows me to take it to the dealer. i have been looking on the hyundai forums for information and this appears to be on the forums a lot. several have resulted in accidents, even a total loss of one person?s car. the forums are saying that there is a voluntary recall and it has to do with the master cylinder, dealer replaces as the complaints come in. i guess i will find out. *tr
