The hydraulic electronic control unit (hecu) in my vehicle needs to be replaced per the Hyundai dealership service department, at a cost of $2600 ($1900 part/$700 labor). The brake pedal presses all the way to the floor and does not stop the vehicle reliably, nearly resulting in accidents on more than one occasion. The car is no longer safe to drive. I have read countless complaints in Hyundai Genesis owner forums regarding the failure of these hecu modules in 2009-2012 models, which Hyundai has clearly been aware of since 2013, but as far as I can tell, has done nothing to adequately resolve. This is a serious problem that affects the safety of the owner and their families, and it seems outright criminal that Hyundai has not been forced to replace these hecu modules on every model produced with these failing parts. NHTSA campaign 13V489000 addressing the internal corrosion of the module due to dot-3 brake fluid does not cover my VIN due to the manufacturing month in 2012 (when supposedly a different hecu began being used), but as many other owners have complained, the manufacturing dates that Hyundai claim the problem affected are clearly not accurate. Hyundai was/is aware of this very dangerous part failure and should be held accountable for the safety of the vehicles they produce. I did nothing but rave about this vehicle before this problem and planned on being a Genesis owner for life... I'm now disgusted.

I was driving to my work. I saw red light signal and stepped on brake pedal. But the pedal just went down very softly without stopping my car. My car stopped after I pressed full force on brake pedal. By the time my car stopped it already passed 15 feet from the stop line where I had to stop.

Trouble with pushing down hard on the brake pedal and concerned with brake effectiveness. And safety. Forced to push brake all the way to the floor in order to stop.

Intermittent brake failures. Seems there has been a recall for bad brake fluid on this model year Hyundai Genesis sedan. Hyundai would not cover this vehicle under the recall when contacted. The vehicle has an intermittent soft brake pedal which goes all the way to the floor under hard and soft braking conditions, whether moving fast or slow and in all weather conditions. The brake pads and all 4 rotors are in good repair. There is no air in the brake lines. It appears to be the ABS module that is failing and causing unsafe braking conditions without warning. There are numerous online forum complaints about this module which seems to be a fault in design by Hyundai. My hope is that NHTSA can inform other owners of this model year that unsafe braking conditions can happen at any time from failure of this ABS module.

Sporadically the brake pedal goes all the way to floor. Pedal has to be pumped 2-3 times before brakes engage. This has happened on 3 driving occasions over 10 days. Took it to dealer this morning who said unless he could replicate issue, he will not repair despite prior recall for same issue. Yesterday on phone, he said he would inspect and file claim with Hyundai. Apparently brake fluid was replaced in 2013 due to recall by prior owner. Now same thing is happening. Problem occurs until engine is turned off. 3 times in 10 days is frightening. Fortunately, I was far enough behind car in front to have time to pump brakes.

I was driving and went over a slippery area at around 40 mph in the city while braking and my brakes went down to the floor. There was no car in front of me so I was able to slowly come to a stop. However, since then my brakes have not been functioning properly, they slowly go down to the floor under any braking condition. And when I stop at a stop light the pedal continues to depress until it's at the floor. In the past I had this issue when I went over a large dip while braking. However it reset itself shortly after and I didn't have the issue again until today. My car was part of the large recall for the Genesis in which the brake fluid was replaced.

The contact owns a 2012 Hyundai Genesis. While driving approximately 25 mph, the brake pedal was depressed and traveled to the floorboard. The contact coasted to the side of the road to a complete stop. There were no warning indicators illuminated. The vehicle was taken to an independent mechanic, but the failure could not be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 87,000.

My wife and I have a 2012 Hyundai Genesis 3.8 sedan. My wife is the primary driver. She came home one evening and told me that the car failed to stop and went into the intersection as she attempted to stop for a red traffic signal. I immediately drove the car down the street and observed that you had to pump the brakes to stop and the pedal went to the floor. I added some brake fluid and pumped the brakes. I drove the care the next few days and noticed that over time the same thing happened with the pedal going to the floor. I took the car to my mechanic and had all the brakes changed. That cost me over $320. The mechanic advised me that the car had a faulty master cylinder. To shorten the story. Due to the dealer cost of from $275 to $365 for a master cylinder. I bought 2 online and 1 at oreilly auto parts. I spent $105, $81, and $79 for each respectively. Each time the mechanic advised me that the were not compatible. He was so conflicted by the process advised me to take the care to the dealer and told me that with only 91000 miles and a well maintained 4 year old car, it is unheard of for a master cylinder to be faulty. I contacted Hyundai and was told there was no recall nor was my vehicle covered by my factory warrantee. I am a retired auto theft officer so I decided to check with NHTSA for complaints and recalls. I am positive that this recall applies to my car. I have had the same process happen to me regarding the windshield wiper motor. Hyundai would not help so I found a motor at a junk yard. I paid to have it installed. However it only works at one speed. I would like it replaced and a refund for the cost incurred to find and replace it. I also would like the braking system repaired and compensation. Hyundai's recall number is 114. I would like to invoke the lemon law..

When driving on freeway at 65mph the engine missed then stalled. I lost power steering and power brakes. Multiple warning lights on. Dealer is not finding anything using computer diagnostics. Loss of steering and brakes at high speeds is not good!!!!
