While driving on H street ne in Washington DC during the day, I applied the brakes from a speed of approximately 25 mph. As I passed over some gravelly surface, the anti-lock mechanisms activated. After the initial rapid pulsation associated with antilock braking, however, the brake pedal went soft and traveled nearly the full distance to the floor before re-engaging. The brakes remained in this condition for several minutes, but they returned to normal after about 10 minutes and several applications. The incident occurred again on a gravel road in late July 2012. This time the brakes never returned to normal. Instead, to apply the brakes, I would have to push the pedal nearly all the way to the floor. The local Hyundai dealership took my car in for service, and after a few weeks and different attempted solutions, fixed the problem. The problem has not recurred since July 2012.

Brake malfunction; repairs done at dealership.

While approaching stopped traffic on interstate-70 I applied brakes hard enough to engage the ABS system. Subsequent braking resulted in the brake pedal having excessive travel to within 1/2 inch of the floor board, making future stopping very unpredictable and resulting in multiple near miss accidents. The brake pedal corrected itself within about 3 days of normal driving. This exact same thing has occurred every time the ABS has been engaged, which is at least 3 additional times since the first incident. Each time the problem has cleared up in about 3 days, but the brakes are very unpredictable and dangerous during that time.

My wife was coming to a stop and the brake pedal immediately went all the way to the floor and luckily for me she instinctively pumped the pedal and it eventually stopped but it scared the living crap out of her! she then proceeded on the freeway and at some point traffic became stop and go and she was nervous driving in it which I don't blame her. Now she is afraid to drive her own car which is her daily commuter"?" ]now the car just came out of warranty and I already know that I going to catch[xxx]trying to get this [xxx] ABS thing replaced!! it's apparent what is causing the issue based off the same complaint. When in actuality it should be covered by Hyundai!!! information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

4.6L traveling at 50mph and applied brake to come to a stop at a traffic light. Brake went all the way to the floor. My car was packed with children and I went into panic mode as I had to pump my brakes to bring the car to a stop. I had brakes one moment and no brakes the next moment. After several hours, the issue has not gone away and I'm scared to even drive to dealer. After research online, it is a shame to see the ongoing issues with this problem alone with accidents involved. There should be repercussions to Hyundai. This is one of many costly issues with this car. It's a money pit for less than three years!! this issue is by far the scariest of them all.

Driving about 40 mph, when I had to stop suddenly for the red light at the intersection, for some reason brakes was real soft. It was very clear that I wasn't able to stop the car as expected, checked all the fluids and brakes for any leaks. Everything looked normal but brake pedal still go all the way to the floor.

While driving with family on day before father-in-laws funeral my brake pedal went to floor. After restarting several times same thing experienced. No fault codes seen read many online forum posts with same problems. Braking power reduced by approx 70%. scary to drive car now. This should be recalled. All posts point to ABS unit failure. Dealer called for and did tsb change to high temp brake fluid at last service. Related to attempt and prevent this?? could very well be. Please help.

All brake lights failed no indication to operator

- Fleming Island, FL, USA

This is the second time brake lights failed. No indication to driver. Almost caused an accident. Same diode package replaced as the first failure reported less than a year ago and 5 K miles. Updated 10/22/13 the consumer statedall brake lights fail including the right, left and center.

- Fleming Island, FL, USA

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.

I was heading to work and when I pressed the brake pedal it hit the floor and the car didn't stopped so I am intermediately pressed the park pedal and my car started spin on the street.

My wife was coming back home from dropping off the kids at school, when traffic was coming to a stop in front of her. When she tried to apply the brakes, the brake pedal went to the floor with almost no resistance. Fortunately, she was able to stop before she hit the other stopped cars. The dealer has informed me that the ABS module has failed on the car. From looking at this site, I am not the first driver with this problem. Seems to me that Hyundai got a bad batch of ABS modules. I would appreciate if nthsb could correlate the VIN numbers of those reporting this problem to see if there is a pattern of close vins. Hyundai should make this right as this is a major safety issue. There was no warning or indication of anything wrong with the brakes until they just suddenly failed to operate. The dealer has confirmed to me that there was absolutely no preventative maintenance or service that I could have or should have done to prevent this from happening. Looking through the entries of similar problems at NHTSA and reading through the entries at www.genesisowners.com, I am surprised that no one has died from this issue yet.

I was driving at about 35 mph when I had to slow down due to vehicle slowing in from of me. I placed my foot on the brake pedal. The brake pedal went to the floor, so I began pumping to see if the brakes would respond. The brake pedal responded with an increase resistance and I was able to slow down. Shortly after the brakes responded normally. A few days later my wife had a similar problem with the brake pedal when pressure was applied.

Had to brake hard to avoid debris on hwy exit. Following that the brake pedal began to intermittently fade noticeably. Within 2 weeks it became a chronic issue. Had the brake fluid flushed and replace. No better, had brakes replaced, no better, had the master cylinder and booster replaced, and again no better. I have spent several hundred to resolve this problem. Recently read an on-line forum where many Genesis owners are reporting similar problems with similar problems narrowing it down. The consensus appears to be that the ABS controller is faulty and at a cost of almost $3000 to repair. This is totally unsatisfactory! it isn't just the outrageous cost, but a safety item should not fail as frequently as they appear to be and not on a car that is still relatively "new".

I seriously hope people don't have to die before this car is recalled for brake failure problems. I am having an issue with my 2009 Genesis where all of the sudden the brake pedal becomes very soft and goes all the way to the floor. I initially thought this was a one-time fluke. Well now the brake pedal has occasionally goes all the way to the floor without any pressure being applied to brake system. The best way I can describe the problem is the brakes are good and then they are bad on the next application. No warning lights, no gradual deterioration, just instant no brakes. Pumping seems to improve the brakes slightly but they rapidly faded when held. No brake fluid leak is observed and brake fluid level is full. From what I am reading this is not a sporadic problem if you look at how many of us this is happening to!!! I pray this Hyundai problem does not end up in a serious accident and someone being killed. This car is completely unpredictable and unreliable. The brakes work fine until they decide not to work. This is some scary stuff.

Last week I was driving my 2009 Genesis without any prior incidents or notification, the brakes went out. The car did not stop and it only stopped when I bumped the brakes and pushed the pedal all the way to the floor. Luckily, no car was coming the other direction as the car finally stopped half way in the intersection. The vehicle was taken to the dealership and they advised me the vehicles ABS module system failed, not covered under warranty. The cost to replace this part is very expensive. Im very afraid to drive my vehicle. Apparently, Hyundai has known about this issue since July 2012. This is a huge safety issue.

Approaching a red light, pressed the brakes, peddle went soft (no pressure). The car did not stop immediately, only slowed down. Luckily, I allowed much space in front of me to slow the vehicle to a stop. Immediately took the car to a dealership, they state they can not duplicate. This vehicle has a problem with the ABS hydraulic module from what I have read from other owners who have had this problem fixed under warranty. I am one of the unlucky many whose local dealership will not acknowledge that this repair is necessary. I pray that this problem does not cause a loss of life, however am concerned it might.

Brake pedal went to the floor when approaching an intersection. Vehicle was unable to stop immediately. Loss of braking.

- Oregon, OH, USA

Without any prior incidents or probable causes, the brakes suddenly went "soft", as in the pedal went to the floor and the brakes were practically ineffective. This has happened intermittently since, and from research done online, this appears to be a problem with the ABS brake module, yet Hyundai dealers that I have approached about the problem are unaware that this is fairly common, and are reluctant to replace this rather expensive component without toying around with other perceived "fixes", such as replacing the brake fluid and/or the master cylinder.
