Approached an exit from a parking lot and the brake pedal went all the way to the floor without applying the brake. Was able to pump the brake pedal and get the brakes to work. The pedal now is about half of what it used to be and requires pumping each time the brakes are used to apply the brakes. Pedal is erratic; sometimes I have about half pedal before a firm brake pedal. Other times it is even lower. I have no pictures or documentation to include that would be relevant to this issue.

Brake failure. Brake pedal must be pumped to completely depress the brakes and stop the car. This issue persists throughout use of the vehicle and no matter whether at highway speeds or in town. The issue began suddenly and has been consistent with the vehicle since that point. The brakes not being fully functional render the car unsafe to drive under any driving conditions. Cruise control light turns on intermittently and cruise control is fequently unavailable on the car.

While braking at a stop light, the brake pedal went to the floor and I lost anti-lock function and had to press hard on the pedal to stop. The problem persisted for a day or two, then went back to normal. After about a week, the same problem occurred. After researching this issue, I found numerous cars had the same problem, yet it seems hyundai refuses to take responsibility. There is a recall the federal safety agency campaign number: 13v489000, however when I run my VIN #, no recalls are listed. My car is a 2012 hyundai genesis.

The vehicle was in motion in a busy commercial area. When the brakes were depressed the pedal went to the floor and slowing of the vehicle was impaired. To stop the vehicle required pumping the brakes to return some pedal pressure. The car was driven home and over the course of several stops (pumping the brakes) the pedal force returned to near normal. I am making an appointment to have the car serviced by a dealer.

When applying brakes whether on residential streets, backing out of the garage or on the highway the brake peddle continues to sink to the floor and only provides very little stopping power (something like a coasting stop). Since this recently started happening I have discovered that pumping the brakes helps to get better stopping results but it is now scary to drive. I had the brake fluid replaced as a result of hyundai's campaign 114 recall in july of 2014, however I am now experiencing what appears to be consistent brake failure. I have contacted hyundai consumer affairs and they basically stated that because I had the campaign 114 recall done that there is nothing else they can do regarding the possible hecu module failure as a result of deterioration due to the dot-3 brake fluid exposure. I also find it hard to accept that the hecu module was taken off and the valves inspected by the dealer as part of the recall. I sincerely believe that this issue was never resolved on the original 114 recall and now I am responsible for the repair cost as hyundai is refusing to cover this under warranty. My car has 74k miles on it. Something needs to be done as anyone driving one of these vehicles is in very serious danger of severe injury or death to themselves or others as this car is not safe to drive as a result of an oversight by hyundai.

After driving steadily at 35-40 without braking, applied brakes approaching cars stopped a light. The brake pedal went nearly to the floor and the car only slowed minimally. After several pumps, braking returned and I was able to stop before colliding with the stopped traffic. After that, the car braked normally. This was the 2nd time this happened, the first time being just a few days earlier. The initial episode was less dramatic. There were no warning lights before or after the event. The car is at the dealer for service now. This was incredibly scary; I could have pushed the car in front of me through the intersection into 60mph highway traffic. The brake fluid had been replaced under a tsb at 6,502 miles due to corrosion issues related to the hydraulic electronic control unit (hecu). It's frightening to think this problem may be responsible for a serious brake failure at just 64,000 miles.
