| Description of the problem | 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. |
