I was driving down the road and my brakes had been working fine. On my way to work while approaching a stoplight my brake pedal was pushed all the way to the floor with little result. I am mediately pump my brakes afterwards and the corded stop. The rest of the way to work I had to continuously pump my brakes in order to stop. My brake fluid was checked and was full. I drove home with same issue and have not drove car since. When the problem first happened I came off a highway exit to a stop light.

My father is currently looking after my vehicle and while he was doing routine checks when went to depress the brake petal it sank all the way to the floor. He later took it to a mechanic who then bleed the system a few times only to find out that the front right brake and rear left brake are operating as normal. As it would turn out, however, Hyundai issued a recall for this but only for the genesis sedans and not the coupes. Hyundai recall #114 and NHTSA recall #13V489000 state the brake fluid the manufacture uses does not protect the H.E.C.U. or hydraulic electronic control unit (a.K.a. ABS control unit) against internal corrosion. So the internal valves will corroded and prevent the brakes from operating properly. In my 2011 Genesis coupe this is currently the issue. Other coupe owners are having similar issues where they can't stop the car proper and/or the brake petal sinks to the floor at random times while driving slow or at highway speeds and the brake don't operate properly or at all! the manufacture seems to be aware of the issue but won't do anything about it. Replacing the master cylinder and completely bleeding the system doesn't have any affect for the issue. To replace the unit, I'm looking at roughly $3,200 of my own money to replace the H.E.C.U due to defective brake fluid that has corroded the internals. The car has barely been driven with less about 30K miles on it. This a grave safety concern and Hyundai needs to address the issues for not just the sedans but the coupes as well! if I or the driver of my car needed to make an emergency stop there is no telling if the brakes would operate in that moment as they should. Injury or death could occur for not just the driver but other casualties that could be prevented if Hyundai fixes this issue for all Hyundai Genesis coupes. Brake operation is vastly important in all vehicles. This problem is serious.

The contact owns a 2011 Hyundai genesis. While driving, the vehicle failed to stop normally when the brake pedal was depressed. The contact had to depress the brake pedal to the floorboard to stop the vehicle. There were no warning indicators illuminated. The vehicle was not taken to a dealer or an independent mechanic for diagnostic testing. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA campaign number: 13V113000 (service brakes). The failure mileage was unknown.
