While attempting to brake on exit ramp off an interstate highway, the brake pedal was depressed almost to the floorboard with minimal slowing. The brakes were pumped several times with slowing vehicle speed. Fortunately, the exit ramp was long enough to allow a safe stop. Pedal remains soft and spongy. No warning lights are on. Brakes functioned normally until this incident at 138,200 miles. However, master cylinder was replaced at 102,000 miles for a similar problem at an independent auto shop. I am awaiting a dealer repair time. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
The contact owns a 2010 Hyundai Genesis. The contact stated that the brake lights failed to illuminate. A dealer had not diagnosed the vehicle. The manufacturer indicated that the vehicle was serviced per an unknown recall campaign in 2014 and 2016; however, the failure persisted. The vehicle was not included in NHTSA campaign number: 13V113000 (service brakes, hydraulic, exterior lighting). The vehicle was not repaired. The approximate failure mileage was 102,000.
The contact owns a 2010 Hyundai Genesis. While driving 25 mph, the brakes malfunctioned. The contact had to depress the brake pedal to the floorboard in order to stop the vehicle. The vehicle was repaired. The manufacturer was made aware of the issue. The failure mileage was 16,000.
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!!!!!!!
The contact owns a 2010 Hyundai Genesis. The contact stated that approximatley 80% of the vehicle's brakes failed while driving approximately 50 mph. The failure occurred without warning.

I was driving on spring cypress rd (spring, tx) approaching state highway 249 at 30 mph, I stepped on the brakes at the intersection and the pedal went all the way down to the floor. If I didn't start pumping the brakes, I would have rear ended car on front of me. If this incident had happened while I was on the SH249 freeway, I wouldn't be here filing this report. I was able to drive slowly to the Hyundai dealer using side roads.
Brake pedal goes to the floor without much effort when at a full stop or in motion. Little to no actual braking occurs until reaching the full travel of the pedal. This is very dangerous and the dealership (burns Hyundai of marlton NJ) acknowledged it is the hydraulic control unit, but refuses to replace under the 2013 recall of the unit. They quoted me at $3,024.50.
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.
1) almost hit from oncoming traffic at a stop light, when I was attempting to make a left hand turn. The signal turned yellow so I tried to turn left before I realized the oncoming car was going to run the light. I took my foot off the brake and hit the gas to make a quick turn to avoid the oncoming car. The car stalled for a second as I pressed the gas into the turn, then kicked into full power, screeching the tires. I thought this was a fluke but his same problem of "stalling" for a few seconds when depressing the brake and hitting the gas at takeoff keeps happening intermittently. This is a dangerous issue. When needing to accelerate quickly from a stop, this car has a seconds gap from hitting the gas to the car moving. I've almost been hit twice because of it. 2) the headlights switch off intermittently when using the turn signals to change lanes or turn. They flash oncoming drivers as I click down to turn them on before the turn, or when the turn signal clicks back after the turn. This problem happens almost every time I drive the vehicle with the headlights on. The lights have shut off completely for about 5 seconds while I was driving down the freeway, impairing my ability to see at night. I had to immediately pull over on the freeway in an unsafe location to turn the lights off, then turn them back on to clear the problem. 3) my vehicle had the brake switch replaced from the 2013 recall. However, pressing the brake still does not shut off the cruise control when driving down the freeway. I have to manually turn it off from the button on the steering wheel. I love this car, but I'm afraid to drive my children in it if these problems are not addressed. This vehicle is unsafe and it is going to kill or seriously injure people. Please investigate these mechanical problems and issue the appropriate recalls.
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.
When driving the vehicle, the brake pedal went all the way to the floor and my brakes went totally out. It is a miracle there wasn't a crash with someone killed. There was a recall for this same issue and my recall was done last December but obviously the damage was already done and it did not fix my car. I called that dealership back today and they advised me that because the recall had been done and my car is out of warranty, that everything will be at my expense to repair. I will also have to pay to have it towed to be repaired. Hyundai should be paying for the towing, repair, and loaner vehicle as this was a major safety issue that they have failed to take care of.
Took my 2010 Genesis in for service...brake stop lights were not working. Replaced defective switch. Took my same car in for state inspection on September 9, 2014, brake lights not working again. Replaced defective switch myself because of 2 hour drive to dealer and the safety issue involved with driving vehicle. Something needs to be done! these switches should not fail this often.... this is a very serious safety issue. We don't know how long this switch was not working since there is no way to tell when you are driving the vehicle... thanks!

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.
On 7/1/2014 I was driving at approximately 35 mph when I put my foot on the brake of my 2010 Hyundai Genesis and the brake pedal went all the way to the floor of the car and the car did not stop. The next day I phoned Hyundai about the incident and asked if I could bring the car in for a brake inspection. I was told do to 4th of July holiday they would not be able to look at the car. Since they would not make this a priority I took the car to my local mechanic for inspection on 7/3/14. The local mechanic was not able to determine the cause. Later that day the car had begun stopping as needed with no cause identified so I went back to normal driving but maintained feeling uncomfortable. I had forgotten that previously I had taken my car to Hyundai service to have a safety recall performed on 1/27/2014 (recall #114) that specifically related this this as a possibility. The service involved replacing the brake fluid due to having too low of a boiling temperature leading to eventual corrosion of the hecu anti-lock braking component resulting in reduced stopping ability or complete failure of braking power which is what occurred. On 8/13/2014 once again I went to put my foot on the brake while driving and again my foot went straight to the floor and was unable to stop the vehicle resulting in me almost hitting another car in my work parking lot. I immediately took the car to the dealer insisting they perform a brake inspection. They determined after a few days that it was the hecu unit that needed replacement and proposed charging me $3500 for the repair later reducing that to $2500 when I complained that my vehicle had relatively low mileage and complete brake failure was unacceptable and their responsibility. The cost of repair and other expenses incurred (rental car) is completely Hyundai's responsibility since lose of braking relates directly to safety recall #114.
Brakes completely failed as I entered NJ turnpike. No braking power was restored. Drove in lowest gear and used emergency brake. Second incident with this car in 6 weeks.
The brake lights on the 2010 Hyundai Genesis (and possibly other years/models Hyundai vehicles) have various problems with the brake lights failing to work. This is very dangerous not only to the Hyundai Genesis driver, but also for any driver following behind the car. There has been various factory recalls for the 2010 Hyundai Genesis brakes including one that causes the brake lights not to work due to a brake switch failure: www.cars.com/Hyundai/Genesis/2010/recalls however the particular problem my car and other Genesis owners have reported does not have a factory recall for it, even though it poses the some of the same safety issues that the brake switch factory recall had. genesisowners.com/Hyundai-Genesis-forum/showthread.php?T=3269 the root cause is diode that fails which cause the brake lights not to work. (this is different that the brake switch factory recall.) I don't know how many months I drove without having brake lights. My state inspection was in January 2014. A driver that was behind my car informed me my brake lights didn't work in May 2014. I had my car towed to the dealer due to the danger of driving when the car's brake lights don't work. Apparently Hyundai knows about the issue (according to the above link) : 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." Why is there no factory recall for this problem? it can cause serious accidents which could lead to fatalities.
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.
