Brake system failure. Brake pedal and goes all the way to the floor. Hyundai dealership explained that the HECU has failed. In 2014 there was a recall on this car for this issue, Hyundai Recall 114. This recall was for "GENESIS SEDAN HECU INSPECTION AND BRAKE FLUID REPLACEMENT". The known issue is that the part breaks down over time and just changing the brake fluid doesn’t stop the corrosion process. The HECU part should have been replaced and not allowed to degrade further as it has now done on my vehicle.
2012 Hyundai Genesis brakes complaints
Page 2 of 3: complaints 11 to 40 of 61, newest first, as owners wrote them.
if the brakes are hit hard and ABS engages, the pedal immediately goes soft and stays soft braking is impared bu 50% until the ABS module resets itself randomly but only after parking the car for a while. this has happened 2X to my car and there are multiple reports on the genesis forums about the exact same issue
While in route to the dealer for one issue, my smart cruise light came on. I reported this to the dealer upon arrival and they ignored. They repaired one item under warranty in which I though took care of both. By time I left, allowed the car to warm up; the smart cruise light came back on. I contacted the dealership & asked them what happened to this 2nd issue. They scheduled an appointment and I was informed by that time and visit; the warranty had expired and I will have to pay $4200 to repair the problem that they now see. I had also been complaining about my ABS/ESC/auto hold lights were constantly flashing, now they remain solid. It causes the vehicle to jerk when in reverse. I have read about several recalls regarding issue. The situation has gotten worse and I was told it is now leaking brake fluid. The dealership has now given me a price totaling $7000 to repair or purchase a new vehicle. This is money I cannot pay and I know my vehicle was still covered when the problems/ recalls started. These incidents occurred on several dates.
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.
Tl* the contact owns a 2012 hyundai genesis. The contact stated received a recall notification of the federal safety agency campaign number: 13v489000 (service brakes, hydraulic) and had the vehicle serviced at all star hyundai (3950 century ct, pittsburg, ca 94565). The contact stated that one day after starting the vehicle, the brake pedal depressed to the floorboard without warning. The contact took the vehicle to dick hannah vw of portland (12345 e burnside st, portland, or 97233) where the hydraulic electric control unit was replaced due to the failure. The manufacturer was not notified of the failure. The vehicle was repaired. The failure mileage was approximately 46,000.
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.
Brake pedal goes to floorboard -- can pump and get partial brake - afraid to drive at higher speeds -- have had the master cylinder replaced and brake system bled- did not help the problem
The brake pedal of my car is soft and deep, and the braking is not done properly. After about a month and a half, the symptoms appeared and I changed the brake pads. Every day driving is a continuation of tension. I went to the designated service center and inspected it. During the re-run, the same phenomenon continued, and after a week again, I had to change the ABS module. How much of an ABS module does it have grounded like a brake pad? I can't understand it. I looked at the internet and the model I was riding was subject to recall.
I own a 2012 hyundai genesis and experience a very low grip on my brake pedal. It has just been confirmed from a hyundai dealership that the hecu is bad and needs to be replaced (11/20/19). Hyundai has recalled certain model year 2009-2012 genesis sedans under recall 114 or the federal safety agency campaign 13v489 for the hecu. I have been told, however, that my VIN does not qualify for the safety repair. I find it highly unusual that I am experiencing the identical problem that so many other genesis sedans have faced, yet am being denied the necessary repair. I am asking that my VIN be included in the recall as I am very concerned for my safety at this point. Keeping in mind the safety of others as well, all genesis sedans made during 2009 and 2012 should be re-looked at again. It is a $3000 fix and I cannot tell you how unfair it is to know that other hyundai genesis owners have had their hecu's replaced under the recall. Why is their safety more important than mine?
On october 23rd, 2019, the brakes on my 2012 hyundai genesis r-spec sedan suddenly failed with the brake pedal going all the way to the floor before the vehicle eventually stopped luckily avoiding an accident. I was driving on the highway. The vehicle has 79k miles. I then took the car to the hyundai dealer in st. Louis park, mn and they determined that the brake master cylinder was faulty and replaced. The diagnosis and repair did not fix the issue as the brake pedal was still spongy and going to the floor intermittently. I will be taking the car back to the dealer to have them fix it correctly. While researching the issue, I have found that multiple other owners of the same car have experienced this issue and the dealer had to replace the ABS hydraulic electronic control unit (hecu) as it contained corrosion within the unit due to bad design which causes hydraulic braking failure to occur at any time. This campaign/recall below outlines the issue which I am going to present to the dealer to fix correctly as I am still under warranty. To me, this is a life or death type failure and could result in injuries. Hyundai should be responsible for replacing all ABS hecu before lives are lost for all 2009-2012 hyundai genesis, not just some vins that they deemed troublesome. They should take responsibility for all cars and immediately contact their owners. Hyundai recall - campaign 12-01-052 tsb: bh genesis sedan hecu inspection and brake fluid replacement (recall 114) original recall from the federal safety agency manufacturer's report date october 29, 2013 the federal safety agency action number pe13033 potential number of units affected 43,500
Having issues with brakes going all the way to floor. Have had them replaced and after a few months problem returns. Was this vehicle repaired as part of recall 114 the federal safety agency recall 13v489000.
When the brake pedal was depressed today 08/23/19, it traveled to the floorboard, barely escaping rear ends of several vehicles on the highway and city streets. There was no warning indicator illuminated. There is no evidence of a brake fluid leak. There is the appropriate amount of brake fluid in the reservoir. Having entered my VIN # into this site has provided no recalls. Although reading everything about no.114, that I have sounds like it should be and it should be corrected. Some people, who have also had this problem, said that the brake fluid used was causing failure in the master brake cylinder valves. This is obviously a manufacturer error, and hyundai should be held responsible. I have unfortunately had to leave my car due to this safety hazard over hour and a half from home. This needs to be addressed/fixed quickly.
Driving home last night my entire braking system went out. I lost all control to use the brakes to stop and all indicator lights were lit up on the dashboard. I notice a recall issue with the hecu but looks like my vehicle is not included in the recall. Why is that?
Soft braking, intermittent. Pedal goes down to the floor and must be pumped to stop. I took it to my go-to guy who specializes in brakes and he couldn't recreate it. He took look at everything and couldn't find issue in the brakes themselves. Recently happened again.
Tl* the contact owns a 2012 hyundai genesis. When the brake pedal was depressed, it traveled to the floorboard. There was no warning indicator illuminated. Napleton's north palm hyundai (3703 northlake blvd, lake park, fl 33403, 1‑888‑691‑9402) was contacted and stated that the VIN was excluded from the federal safety agency campaign number: 13v489000 (service brakes, hydraulic); however, the vehicle exhibited the same failure as the recall campaign. The vehicle was inspected by an independent mechanic. The manufacturer was notified of the failure. The approximate failure mileage was 45,000.
Brake pedal began is requiring more and more travel to achieve braking effectiveness. There is no evidence of a brake fluid leak. There is no reduction of brake fluid in the reservoir. The ability to modulate braking is impaired at times and one must pump the brake pedal to build pressure to stop.
Ref: the federal safety agency campaign no 13v489000 hyundai genesis 2012, 4.6l, v8, 4 door sedan, with approx 77000 miles. In the last 6 weeks we had the brake pedal go all the way to the floor 3 times with little or no braking occurring. Two weeks ago this car was taken into liberty (feldman) hyundai in new hudson, mich for repair of this brake problem. After $95 for an 'inspection,' which did not include any oil change, the report was that no problem was found. This car was serviced in march, 2014, per hyundai recall no. 114 bh hecu, which called for inspection and replacing the brake fluid. This was done. There have been no brake problems since that time until about 6 weeks ago. This car was serviced in march, 2014, per hyundai recall no. 114 bh hecu, which called for inspection and replacing the brake fluid. This was done. There have been no brake problems since that time until about 6 weeks ago. This car was serviced in march, 2014, per hyundai recall no. 114 bh hecu, which called for inspection and replacing the brake fluid. This was done. There have been no brake problems since that time until about 6 weeks ago. The bottom line is that even though hyundai recall no. 114 was accomplished, the problem was never fully corrected. Some people, who have also had this problem, said that the brake fluid used was causing failure in the master brake cylinder valves. This is obviously a manufacturer's error, and hyundai should be held responsible.

Sometime the transmission shift very hard while driving,it has a wild unexpected jerk
2012 genesis sedan consistently stalls under medium to low speeds while braking or making a turn. All warning lights come on and loss of steering and braking occurs. Car is difficult to control safely without use of emergency brake due to the loss of steering/braking. This incident now occurs with each car trip while traveling on all kinds or roads and at various speeds but not more than 40 miles an hour. I am worried for the safety of my wife and 3 year old child since I take them everywhere with me. Car has been at hyundai dealership for 4 days and they can not diagnose the problem because there are no fault codes to look up.

My windshield wipers do not clear the windshield properly in inclement weather, my brakes sometimes make scrubbing sounds, my tires seem slippery sometimes when turning a curve, and my car jerks sometimes when pulling off after sitting still.
Emergency parking brake suddenly activates without touching any controls. Epb light appears on the dashboard. When car is placed in park, epb light goes off but epb is still engaged. Epb light reappears when car is placed in drive and epb is still engaged. Turning off engine and restarting does not solve the problem. Only way to solve the problem is to place the transmission in drive and floor the accelerator. Epb makes loud noise and there is significant resistance from the epb but the epb finally disengages and car drives normally. Smell is present from the epb system and resultant examination of system shows flaking of pad from heat caused by procedure. Dealer has been informed of problem since 2013 but says it can do nothing because it cannot replicate the problem. Diagnostic shows three codes dealing with epb system but dealer says codes are "general" in nature and do not pinpoint the problem. Says nothing can be done until problem is replicated in presence of dealer. Failure has thus far only occurred when vehicle is stopped but my fear is that it will happen when the vehicle is moving. Putting pressure on the brake pedal and attempting to disengage the epb using the epb tab for "engage/disengage" does not work. Date given below is the latest occurrence. Problem has existed on and off for more than three years. Problem occurs randomly and intermediately. Vehicle left with dealer on three separate occasions but dealer could not get problem to occur and will not make repairs because of this.
My ABS brake module failed on tuesday afternoon 12/13/17. I had very little braking power, pedal goes to the floor. I bought it to the dealer and they said the brake module needs to be replaced. We were going straight and almost hit the car in front of us. I bought the genesis in oct. 2011 new. It is a 2012 with 32,789 miles.
