My son was driving this car home from college mid-day on October 8. He had not driven the car for 10 days or so while at school and he did notice the brakes making an unusual sound that day he had never heard. While on the highway, there was a sudden stop ahead of him. When he pressed the brakes they completely stopped working and he rear-ended the car in from of him. The brakes were completely non-functional after the crash and he had to try to stop his car as best as he could without brakes. Luckily there were no injuries, however complete brake failure out of the blue is obviously enormously dangerous. The tow truck driver confirmed that brakes did not work at all and speculated that a "brake-line snapped". I have no idea if that is true or why he thought that. The car is totaled and no inspection of the car has taken place. We have the car at our house and it is available for inspection as we try to figure out what to do with it. There were no warning lights prior to the issue. Less than a week after the accident we received a Notification of Extended Warranty from the car manufacturer regarding a possible issue related to brakes. And we have read about other braking issues that have evidently arisen over the years with this model year car.

My Hyundai dealer called me today May 15, 2019 and said that the estimate to repair my Genesis brakes would cost $2770 at a minimum, maybe more if the whole system had to be replaced. In other words; (please write a blank check to us.) this is a Hyundai problem as a manufacturer. They put dot 3 fluid in the system at birth of the car and it caused corrosion interacting with the zinc plating internally. Proper testing wasn't done prior to assembly signoff. The recall changed the fluid to dot 4 and in my case the fluid was not property drained and changed and my pictures of the fluid prove the separation and crud in the brake system. Many Genesis have had this problem and Hyundai should be forced to make this repair on the affected cars. What is a bigger safety concern then having your brakes go out when applied. My car won't stop as the brake pedal goes to the floor all the way down.the ABS & ESC lights come on when this happened. The brake fluid was changed in 2014 and again in 2019. A new master cylinder, front brake lines, brake light switch and diode was installed in March 2019. Took it to dealer in April 2019 and they all was ok except ESC light was on. Drove it home and less then 60 miles the brakes petal again went to the floor. Taking it back to dealer in lima, oh on May 15, 2019. I put in a complaint to Consumer Affairs@hmausa.com, but the girl who returned the call, read from a script and said sorry, your car is out of warranty. Please reference your case number 15737333. This car is unfit to drive and from other postings, it will cost $2500 to repair. The cars value is between $3600/5600 dollars.this is an on going safety problem that Hyundai has put off making a proper repair, relying on time and miles to get out of a safety recall. I'm uploading photos of brake fluid taken from my car in March and April 2019.

My brake lights will not come on when I press the brake pedal. I have had the fuses checked and they are all working. I contacted my local Hyundai dealership after researching the recall on the brake light switch. They will not perform the recall because they said it was already done twice. But there is obviously a proble if its happening again.

The contact owns a 2009 Hyundai Genesis. The contact was informed by eyewitnesses that the brake lamps on the vehicle failed to illuminate. The vehicle was serviced per NHTSA campaign numbers: 14V713000 (exterior lighting) and 13V113000 (service brakes), but the remedy failed to repair the vehicle. The manufacturer was not notified. The dealer advised the contact to bring the vehicle in for diagnostic testing, but the location was over an hour and a half away. The failure mileage was approximately 165,000.

Brakes lights have gone out. Hyundai is aware of the problem but I am not aware of any recall. Hyundai issued tsb 09-be-023 technical service bulletin 09-be-023, stop lamp Z01 diode inspection procedure, appears to describe the location and procedure for troubleshooting of the diode but describes the issue as "... vehicles may experience the stop lamps blinking on and off even when brakes are not applied."

I own a 2009 Hyundai Genesis clearly affected by the recall on brake fluid that affects the brake module. My car has been deemed too dangerous to drive, but was never included in the recall efforts according to my service advisor. I being asked to pay an exorbitant amount to replace the ABS module. My advisor has informed me that my VIN # is not included in the recall efforts. So, it appears that although I own a 2009 which is a year that is affected with this problem....my safety does not matter for some reason. My car is experiencing the same issues and will probably create an accident if it is driven. My car should also be included and I do not understand why it is not. The brakes can be depressed all the way to floor board and the car will still begin to roll forward. It will not stop completely! this has been an ongoing issue for a months now and the dealer is telling me my car is not covered by this recall! I am putting today's date, but it has been months now and my safety should be considered as well before something terrible happens.

- Bakersfield, CA, USA

The contact owns a 2009 Hyundai Genesis. While driving and attempting to stop the vehicle, the brake pedal traveled to the floorboard. The brakes had to be pumped in order to stop the vehicle. The vehicle was taken to the dealer for diagnostic testing and it was determined that the brakes were fine. The contact stated that the brake failure recurred the very next day. The vehicle was taken to an independent mechanic where it was diagnosed that the master cylinder failed and the ABS hydraulic unit needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 39,305.

My wife and I have both experienced the same problem. While in motion and have had to come to a stop the brake pedal bottoms out and have had to pump the pedal to bring the car toa stop. Took the car to the dealership; nothing was determined to be the problem. This has occurred several times.

- San Antonio, TX, USA

While driving at low speed, and applying brakes, my break pedal went all the way to floor. No lights or warnings were displayed. This condition continued until home. The next morning brakes worked normally and have for two weeks now.

- Baton Rouge, LA, USA

The contact owns a 2009 Hyundai Genesis. While driving approximately 60 mph, the contact applied the brakes and the brake pedal traveled to the floor. There was no resistance. The vehicle was able to stop slowly. The contact placed the vehicle in park and continued to pump the brake pedal to increase the tension and the brake pressure returned to normal. The failure recurred intermittently. The vehicle was not diagnosed nor repaired. The approximate failure mileage was 89,000.

- Ypsilanti, MI, USA

2009 Hyundai Genesis, in motion street and highway. Total brake failure. No warning, no dashboard light warning. Columbia Hyundai advised that the brake failure is due to failure of the ABS control box. In other words total, un-announced failure of anti skid control box caused a complete brake system failure in this car.

- Cincinnati, OH, USA

When attempting to stop the vehicle the brakes went low to the floor. Took to dealership said that the ABS system needed to be replaced. This is a known issue with the 2009 Genesis but since they had checked it in 2014 it would not be an issue for us. This was not true and others may have the problem if the ABS system is not replaced.

- Voorhees, NJ, USA

The contact owns a 2009 Hyundai Genesis. While driving approximately 75 mph, the brake pedal felt stiff and made an abnormal noise. The vehicle slowed down to 30 mph and would not increase when the accelerator pedal was depressed. There were no warning lights illuminated. The contact proceeded to pull over to the shoulder and called roadside service. The vehicle was turned off and restarted. The electronic stabilty control light iluminated and the vehicle resumed normal operation. The dealer stated that the brake rotors overheated. The mechanic was unable to duplicate the failure and the vehicle was not repaired. The manufacturer was notified. The approximate failure mileage was 70,060.

On September 19, 2015, when approaching a red light, the brake pedal went all the way to the floorboard and the car would not stop. Repeated pumping of the pedal finally brought the car to a stop. Within an hour a second event occurred on the freeway when approaching another car from the rear. The brake pedal had no resistance and went all the way to the floorboard. It has not occurred again. Two days later I took the car (carefully) into the dealer. They have, as yet, been unable to replicate the problem (as Hyundai requires for warranty consideration). However, I will not drive this car or let my wife use it until this is diagnosed and repaired. It is extremely unsafe. This type of brake failure has been noted repeatedly in the 2009 Hyundai Genesis. I am stuck with an unusable car and a manufacturer who will not recognize the severity of this issue. The dealer does not want to repeatedly subject their staff to the risk of an accident but Hyundai requires the problem be validated by another occurrence when driven by dealer staff.

On 9/16/15 the brakes on my 2009 Hyundai Genesis failed and the car would not stop as the brake pedal sank to the floor. I finally got the car to stop with excessive pumping of the brakes. On 9/16/15 I brought my car into jim ellis Hyundai to fix the problem. The dealer inspected the car and couldn't replicate the issue I had experienced earlier in the day. The dealership ran diagnostics on the car and did not find any problems and now the brakes seem to be working fine. My car has 115,561 miles. This is the second visit to the dealership for this problem. On 04/30/15, I brought in the car for two recalls, one that included a brake fluid flush. A month later, I had a similar incident while driving on the highway that caused me to lose brake pressure.after a few days the problem subsided. I am seriously concerned about the safety of this automobile, especially after reading so many similar incidents already filed with the government.

At approximately 7:50am on my way to work, heading westbound on rodeo rd and was going to make a left turn at cloverdale my car stalled. During the stall the engine cutoff and the electrical power in the car seemed to reset itself. As I was coming to a stop, I could feel the brakes not working and I put the car into park and tried to restart the engine by pushing on the start/stop button. When that didn't work, all the power in the car went out and nothing worked, no emergency lights, no power anything. I called roadside assistance and had them tow to the nearest dealership. This is the second time this has happened. The first was on Sunday night September 6th, 2015 at around 8pm in san jose. I put that as a complaint on this system at that time.

On 5/11/15 the brakes on my 2010 Hyundai Genesis failed and the car would not stop as the brake pedal sank to the floor. On 5/12/15 I brought my car into global auto mall and drove very slowly to the dealer, pumping the brakes at every stop along the way to get the car to stop. Global auto mall diagnosed the problem and replaced the master brake cylinder assembly under warranty. My car had 45,381 miles on it at the time. On 8/29/15 the brakes on my 2010 Hyundai Genesis failed again and the car would not stop as the brake pedal sank to the floor. On 8/31/15 I brought my car into global auto mall driving very slowly to the dealer, pumping the brakes at every stop along the way to get the car to stop. My car had 49,179 miles on it at the time. Global auto mall has stated that after running diagnostics on the car they did not find any problems and now the brakes are working fine. A recall on the braking fluid that caused corrosion on the ABS module was performed on my car already, but there is no way for the technician to actually check for corrosion inside the ABS assembly. I do not feel that the car is safe to drive and the brakes are going to fail again, as nothing was repaired on my vehicle.

Brake pedal suddenly requires more travel to engage brakes. It requires a lot of force to get the pedal to engage. Had brakes checked by independent mechanic and all signs point to hecu. Hyundai will repair newer models of the Genesis but for my year they are not. It appears to be a common issue with other owners of the Genesis, as well.

- Walled Lake, MI, USA

Brake pedal almost went to floor before it started to come to a stop. We didn't hit anything because we were in parking lot but if this had happened on the highway, there would have been an accident. This problem started suddenly and has continued. The car is now in a repair shop. There was a recall to replace the brake fluid and this was done in January 2014. The wrong brake fluid was in the car for four years before it was replaced. It seems reasonable that this current brake failure is due to the four years of improper brake fluid although Hyundai will take no responsibility for this brake issue.
