2010 Hyundai Genesis: ABS light or ABS activating

Filed May 12, 2016 · Brakes · 100,000 miles · GA · crash

As I was driving down a major street traveling around 35 MPH, the car in front of me began to stop. As I began to apply the brakes, my car's pedal went to the floor. I pumped the brakes a few times and began to get some pressure, but I was not able to stop in time before rear ending the car in front of me. I never knew what the issue was and I couldn't get the problem to duplicate, but the brake pedal was soft since that day. I have changed the pads, and rotors, so those are not the issue. This week, my fuel pump went out and I took the car to the mechanic for that issue. My mechanic informed me that the car needed an ABS pump. The dealers are well aware of the issue because when we checked the price of the part ($2600), the parts agent immediately knew the problem. There are numerous complaints online about the exact same issue. This is truly a safety issue for these cars. There are many complaints online with the same problem!!!!!!!

I had two prior incidents where partial to complete braking failure occurred previously, but the issue was only temporary (a single stop). This incident persisted for duration of my drive, prompting research into the issue (and discovery of the known ABS hecu corrosion issue. I was attempting to slow and make a turn onto a sidestreet on the way to work, when the brake pedal went to the floor with minimal resistance (and limited braking effectiveness). This prompted a panicked pumping of the brakes to eventually stop the vehicle 5-10ft shy of the rear bumper of another car. After carefully testing to ensure I had some braking effectiveness, I finished the short distance to my office, noting that the pedal remained very soft, going to the floor with ease, and having limited success in stopping the vehicle. I shudder to think what would have happened had this issue presented itself at highway speeds. I have already contacted hyundai corporate and dropped my vehicle off with a dealership for recall repair. I am hoping this incident, coupled with my manufacture date (prior to june 1, 2010 cutoff date) will justify a full ABS hecu replacement under recall.

Driving about 10 MPH on tight curvy country road, brake pedal went to the floor. Pumping the pedal got the car to stop. Dealer said the brake force distribution module failed, allowing brake fluid to simply bypass being sent to the brakes. This is a very dangerous failure mode; it should fail by eliminating ABS but still giving full brake force. There was no indication on dash lights that anything had failed.

When I pressed on the brake pedal, it felt mushy. Completely different from the firm braking the vehicle brakes had exhibited just a few minutes previously. I could feel the brakes trying to engage at the proper brake pedal placement but then I had to continue pressing the pedal because the brakes were not engaging. Only after I continued to apply pressure to the brake pedal toward the end of the pedals range of motion did I finally feel the brakes begin to slow the car. After this first occurrence, since I was over 300 miles from home, I had to anticipate any braking I needed to do. I found that each time I needed to brake, if I pumped the brakes after the first initial pressing of the brake pedal, I could get the brake pedal to build up pressure so I would have close to the same braking 'feel' that I had before this problem began. I returned home on saturday. I did not drive the car on sunday. On monday, I took the genesis to the hyundai dealership. After almost two hours, they said they had identified the problem as the master cylinder. I had the master cylinder replaced on tuesday. There was almost no change in the mushiness of the brake pedal. After searching the internet for possible causes I discovered hyundai has had considerable complaints about fading and mushy brakes on their genesis line of vehicles. It seems it all stems from the hydraulic electronic control unit module. So, with hyundai knowing this, why did the service department of the abilene, tx dealership recommend a master cylinder replacement when, in my estimation, the first culprit should have been the ABS module? I discovered this persistent issue with the genesis vehicle on wednesday, I have an appointment with the abilene tx hyundai dealership on thursday. I'll see how they respond.

Brakes failed - so master cylinder was replaced by dealer but brakes are still a bit spongy. Abs is not working quite right. Brake fluid had already been replaced 6 months earlier under recall, but brake control unit was not replaced. I am concerned that control unit should have been replaced and by other reports it seems hyundai is very reluctant to pay for that. Car is still under warranty.

As I was exiting the highway, the brakes went almost all the way to the floor. The rest of the trip I needed to pump the brakes to enable me to stop. I took it the hyundai dealer the next day and they said it there was a recall for the ABS module. I had the dot4 fluid recall done on december 3rd 2013 (up until then I had never had a brake issue) and apparently the ABS module recall came out dec 20, 2013. The dealer replaced the module under warranty and now the car brakes fine. I just wanted to document the failure.

I was traveling approximately around 45mph when I pressed on the brake to stop at a intersection. However the car had other plans and didn't stop as desired due to the brake pedal going to the floor! Thankfully, no traffic was in the oncoming lane and the turn lane for me just turned green. I was able to go around the car ahead of me and make the turn without incident. I then proceeded to limp the car over to the local hyundai dealership here in jacksonville, fl. They diagnosed it as a bad ABS module for the brakes. My 3rd party warranty company wouldn't repair the car due to no check engine light coming on from this brake failure. Key hyundai repaired the car at no additional cost to me even with my car having 63k miles on it. Another thing to note is that they had just changed out the brake fluid due to a tsb a few months prior of which the old fluid could cause corrosion on the brake system from what I understand.

Several months ago when I attempted to brake, the pedal went down to the floor. However, upon stopping the car and restarting the engine, the car appeared to be normal. I called the dealer and reported the problem and was told by the service writer that if it was not "doing it further" and there were no warning lights there was no point in bringing the car in. Today, I experienced a total brake failure; this time I was in a parking lot and the pedal went all the way to the floor and I was only able to stop the car by letting it reduce to coasting speed and shifting into "park". As I was only a few blocks from my house, I was able to limp home, pumping the brake to stop. My husband called the dealership when I got home and was told to bring it over. The dealership is about 4 miles from our house, my husband drove very slowly and found that upon pressing the brake pedal there was minimal braking and then complete fade out of the brakes. He used the parking brake to stop the car when necessary. When the car was examined at the dealership they reported to my husband that the ABS module had failed and needed to be replaced. (it is important to note that this failure took place without warning and without any indicator lights, either the ABS light or the brake light, indicating that there was a problem.) before filing this complaint, I looked online and found many, many complaints of the exact same problem. Why hasn't the federal safety agency ordered an investigation or recall?
