Lost all braking ability while driving. Had towed to a shop and they were finally able to recreate the issue. There are no error codes indicated when they hook up to a computer. Have bled brakes and still not fixed. They are telling me they've done all they can do.

Received recall notice on 4-16-24 and immediately called for an appt to repair ABS problem. I was told that the part was not available at this time and should call back in a couple of weeks. I called on May 2, 2024 and scheduled an appt. for May 7. After waiting for over an hour, I was told that, yes indeed, my car needed repair but could not be done at that time as this was only an inspection to determine that a repair was needed and someone would call when the part is available but they don't know when. I feel like I was given a run around.

On Feb 15th 2023 my daughter was driving my 2014 Hyundai Sonata at the posted speed limit of 55 MPH on a 2 lane blacktop when the car suddenly and without any warning at all, lost all power and became unresponsive while traveling with other vehicles behind her, in front of her and in the opposing lane of travel. Without enough of an improved shoulder to pull to the right and a steep embankment on that side of the roadway as well, she was forced to veer to the left with other cars approaching. She had minimal braking, steering and no response to depressing the accelerator pedal at all. She was able to direct the car onto a paved portion of a feeder road and finally got the car stopped. The cabin filled with smoke and there was smoke all around the car but no fire was ever found. These vehicles are dangerous to the public and have a known engine defect that because of this the manufacturer has implemented a software patch known as KSDS and with this recall in place should have allowed my daughter to reach a safer place than being stranding on the side of a busy hi-way. My car had this patch installed and I was assured that this recall would allow the car to be driven a safe distance and it would be obvious when this patch was active and the engine would be put in "Limp mode" This did not happen, the engine locked

Im not aware what is malfunctioning or failing but I get a warning to not drive the vehicle and I start hearing a beeping sound, when I try to break it makes a harsh screeching sound and tugs the car a bit. It-??s putting my safety at risk bc I drive for work and I can-??t keep having this problem happen on the freeway. I-??m afraid my brakes will fail and not break. Idk what the cause to this is, I-??ve had two different mechanics take a look at this and no codes pop up. No warnings pop up either. This has been going on for almost 3 months. I can-??t drive this vehicle with this problem and it-??s the only one I rely on for work and my everyday needs. If you guys can please help me out or look into it I will be waiting for a response. Thank you

While driving normally on the highway I received the "Hybrid Safety Warning: Do Not Drive!" error. The engine began sputtering uncontrollably, the brakes weren't fully responsive and I lost power steering. Thankfully I was able to coast down the road and pull over. If this had happened in traffic I can't imagine an accident would not have happened. Not being able to brake safely or steering properly while your engine is sputtering out of control is terrifying and a MAJOR mistake in design and implementation.

I have a 2014 Hyundai Sonata, when I get in and press the brake pedal it is hard to push in and the car won't start till I try to pump the break pedal hard several times till it gives just a bit, then I can start the car up. I know there was a recall for the 2011 and 2012 cars, this report mimics the issue those cars have had a recall for. Once the car starts the brake pedal does work normally, till it sits and then it gets hard to push in again. I took the car to the dealer to be looked at and they wanted to keep it for a week before anyone would look at it, with $200 to start. I couldn't be without a car for that long so they didn't keep it.There were no warning lights and never have been. My fear is that the brakes will fail while driving..

My vehicle stopped on the side of the road in oncoming traffic and caused a back up because of my power brake system failing when it should have still been in good condition because I had just purchased my vehicle 7 months ago. The brake light came on made my car slow all the way down doesn-??t go over 15 mph and has a skidding sound when braking and it happened again in the street away from home. And this has been seen in multiple vehicles such as the one I have.

While driving it suddenly showing error as -??hybrid system warning, stop and do not drive-?? and -??check brakes-?? then brakes are not working. I turn off the ignition and start car again, then no error.Went to a local mechanic to check codes he can not find anything. This is a serious issue to taken care off as if brakes fail on highway, we may cause an accident. Then I search in google and lot of discussions going around the same incident

From the time of my purchase of the car used in 2016 I noticed the the brake would sometimes make a squeaking sound if the brake pedal was depressed suddenly. In September of 2021 I noticed that a Brake Warning light would come on when starting the car. Sometimes the brake pedal would push to the floor as if there was no brake fluid pressure. I took the car to the Hyundai dealer and asked them to inspect and repair the problem. The problem was determined to be the ABS Pump along with the ABS Assembly. The units were replaced at a cost of $908.91. Later in June of 2022 the noise returned and the brake light again began to light. I didn't lose brakes but the light remained on whenever the vehicle was operating. I returned to the same dealer service shop and they inspected the problem and found DTC C1236. They checked pressure and it had 1054 Bar (needs to be 1000 Bar).The technician replaced the Hydraulic Electronic Control Unit and installed a Hybrid Noise Fix Kit. The cost for these repairs was $3351.15. I am aware of problems with other Hyundai model cars brakes. I hope that our car is safe to operate or park. The dealer confirmed the problems for both repair instances. I do not know if any other authorities have inspected this. I don't have the defective parts. The dealer service center retained them after both repairs.

April 2,2022 I took my car in for an oil change. Immediately after leaving the car smoked as if it was on fire. I was pulled over by Walls Mississippi police department because they thought the car was on fire. I contacted Hyundai. They have not done anything to fix this situation. I have not been able to drive the car since then. It needed oil a week after the oil change April 2,2022. It smokes very bad. It has lost power. The engine knocks. I had to get a rental car at the rate of $1000 for a 3 week rental. My car note is $578. The car was repossessed today because Hyundai would not fix the car so I could go to work and pay my car note. I have numerous emails and receipts. No one helped me at Hyundai. They are making us pay our carnotes. Pay rental fees out of pocket. They only reimburse you for your rental once your car goes into the shop. All Hyundai dealerships have a 2 month wait time before they will let you bring the car in, otherwise it will sit on the lot for 2 months. I have tried 5 times since 2021 until now to get the recalls done. Hyundai Mt. Mariah Memphis kept the car a week and asked me to come get it because they did not have all the parts to complete the recalls. Hyundai Olive Branch Mississippi stated they have a 2 to 3 month wait time as well. No one has loaner cars. I explained this to the claim person Julia at Hyundai and no one did anything to fix this.

3 months after purchasing this Vehicle from a notorious car company, I have noticed while driving on the Highway that a hybrid system warning message has popped on my dash board with the check brakes light blinking and beeping. The car then started slowing down with the brakes not functioning anymore. The car is only usable again after you shut it off, wait for few minutes and turn it back on. After several investigations by a Hyundai dealer, it turns out the defective part is a Hybrid Power Unit of HPU.

The first time this happened I had just parked in front of my house and put the car into Park when I heard a chiming sound coming from the car, and the message Check Brake followed by Hybrid System Warning! Safely Stop and Do Not Drive on the dashboard. I did not drive the car for severals after this. After that, I started the car with no issues and was able to drive it with no issues but 4 days later I got the same message while out driving, I stepped on the brake and heard a grinding noise and the brake pedal went all the way to the floor. I pulled over, stop the engine, turned off the ignition, waited a couple of minutes afterwhich the car started with no issue and I was able to drive home. Today I took it to Hyundai garage for the service dept to take a look at it. I am waiting to hear back.

I was driving in a school zone going 10 MPH and a warning flashed saying "Check Brake" then "Hybrid System Warning! Safely stop and do not drive" The brakes then locked up and the steering wheel became very stiff. I was able to pull over and turn the car off. I turned it back on and the warning was gone. However, the issue continued a couple weeks later and would not reset to a drivable condition, this prompted my husband to take the vehicle to Sterling Acura of Austin to be maintenance. The Power Brake Booster was replaced but the warning still appears sporadically, just long enough to read and then turns off.
