general problems of the 2012 Hyundai Genesis - part 2

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.

The contact owns a 2012 Hyundai Genesis. When the vehicle was started, the brake pedal was depressed and traveled to the floorboard. The vehicle was taken to safford Hyundai (located at 7615 loisdale road, springfield, va 22150, tel: (703) 776-9040) to be diagnosed. The contact was informed that the hydraulic electronic control unit failed and needed to be replaced. The vehicle was not repaired. The vehicle was not included in NHTSA campaign number: 13v489000 (service brakes, hydraulic). The manufacturer was notified of the failure. The contact was provided case number: 10367277. The approximate failure mileage was 46,000.

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.

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.

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.

Brakes went soft after a few minutes of driving. Normal braking through several stop and go intersections. Then a sudden unexpected change which resulted in pressing pedal to the floor and the brakes barely slowed the car. Turning the car off and back on restored braking to normal use.

The contact owns a 2012 Hyundai Genesis. While driving 20 mph, the brake pedal was depressed, but the vehicle failed to come to a complete halt. The contact had to pump the brake pedal multiple times in order to stop the vehicle. The failure recurred on numerous occasions. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The contact was aware of NHTSA campaign number: 13v489000 (service brakes, hydraulic), but the VIN was not included. The failure mileage was 64,000.

The contact owns a 2012 Hyundai Genesis. While driving approximately 25 mph and attempting to stop, the brake pedal extended to the floorboard and the vehicle would not stop. After pumping the brake pedal several times, the vehicle was able to be stopped. The vehicle was taken to the dealer where it was diagnosed that the hydraulic electronic control unit was faulty and needed to be replaced. The manufacturer was not notified. The failure mileage was 92,000.

I was turning to park in my parking space and all of a sudden the car began to accelerate with such speed that I thought it would jump the curb and crash into my home. I was unable to stop the car and the brakes were unresponsive. It hit the curb and finally came to a stop with a terrible shudder/noise.

The contact owns a 2012 Hyundai Genesis coupe. On several occasions, while driving, the contact applied pressure to the brake pedal and heard an abnormal noise coming from the brake pedal. While the brake pedal was depressed, the vehicle failed to stop and accelerated without warning. There were no warning indicators illuminated. The vehicle was taken to geweke Ford (871 e onstott rd, yuba city, CA 95991 (530) 821-2121), but no diagnostic failure codes were found and the failure could not be replicated. The vehicle was not repaired. The contact referenced NHTSA campaign number: 13v489000 (service brakes, hydraulic). The manufacturer was not notified of the failure.

2012 Hyundai Genesis. Consumer writes in regards to vehicle brake system recall. The consumer wanted to voice his concern about the recall that was announced, and how the dot 3 brake fluid was suspected of causing contamination of the heca. The consumer stated his brake fluid was replaced with dot 4 when Hyundai performed the TSB. However, the same heca unit remained in his vehicle. The new recall stated for vehicles manufacturer after June 1, 2010 dealers would flush the hecu assembly/valves and brake system using Hyundai's dealer diagnostic tool and change the brake fluid with fluid containing additional corrosion inhibitor additive. The recall made no mention on inspecting the hecu internals for corrosion. The consumer would like to know, how can Hyundai assure him that his hecu has no corrosion, even in the slightest measurement.

I was driving at a speed of around 35 to 40 mph on a street (that's not highway). I was maintaining a proper distance too from the car in front of me. For some reason the car in front of me stopped suddenly. I responded immediately, but the braking was so soft and I felt like nothing has been done and I bumped into the car ahead of me. I really thought at the time of the incident that, something was not right, but didn't think too much into it. A day after I heard these recall news and I can now totally relate my case with the descriptions of other victims.

I have had no accidents for over 20 years, now I have two fender benders - rear end collisions. The first one, 10/07/11, was at less than or about 5mph and I remember braking as usual but it failed to stop and rear ended the vehicle in front. Only minor damages due to the speed involved. Next, today 11/14/11, I braked when a truck cut me off and merged on to the freeway from an exit only lane at the last minute, still it made contact with that truck, this time moderate damage to my vehicle and none to the truck. The speed here was about 10-15mph. I have observed that when I put my leg on the brake pedal while starting, it goes down a little bit which may be normal, but, I am afraid that such a travel / ply could have happened during the above two collisions because I could not believe that it traveled even after I slammed on the brakes.
