general problems of the 2014 Hyundai Sonata - part 1

My vehicle, a 2014 Hyundai Sonata turbo, is having brake lock-up issues. It seems to be related to the avs (automatic brake system). This happens mostly when the vehicle is parked on a hill and the brakes lock up when I start moving. This has been happening for several months, but my mechanic hasn't been able to find the problem. I made an appointment with Hyundai to find out what the issue is, but they told me there's no recall related to it.

The electrical in the entire car is malfunctioning. Sometimes the brake lights don’t work due to wiring, other times the seats control don’t work and the cables to battery is not connected/firing correctly. Has an entire electrical issue.

The car has abruptly applied braking while driving. I took the car to get checked after that and I was told that there was nothing wrong except that the pads will need to be change sooner than later. I mechanic did tell me that it could be a safety issue because it was an uncontrollable. I than took the car to the Hyundai dealer for them to diagnose the car. They proposed that I change everything, including the brake pedal, which to me, sounded very fishy. One week ago, while driving, the car suddenly jammed on the brakes again. This particular time, it was also emitting smoke, either from the front or the bottom.

The contact owns a 2014 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the hybrid braking system warning light illuminated. The vehicle was taken to two separate independent mechanics, where it was diagnosed with abs module failure. The contact was informed that the abs module needed to be replaced. The vehicle was not repaired. The vehicle was taken to the dealer, where it was diagnosed with abs module failure. The contact was informed that the abs module needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The contact had received an unknown recall notification; however, the dealer and the manufacturer informed the contact that the VIN was not under recall. The failure mileage was approximately 90,000.

I was driving and my car started beeping and the wheel jerked to the left and my car slowed down from 65mph to 20mph and almost caused me to have an accident. After I replaced the breaking module, my battery started shorting out and my car once again jerked off to the side and then slowed down abruptly from 65 mph to 20mph.

Abs control unit/pump is leaking. I was told it's not covered under warranty or recall. Local mechanic states they can't repair it because the part has to be properly programed at the dealership. I've spoken with other Hyundai owners and they have had the same issue.

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.

I am filing a complaint due to the lack of timely fix of this recall. It has been more than four months since the recall was issued (NHTSA recall number 23v651000) with no repair available.

The contact owns a 2014 Hyundai Sonata.  the contact received notification of NHTSA campaign number: 23v651000(service brakes, hydraulic); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. VIN tool confirm parts not available.

Vehicle displaying "hybrid system warning! safely stop and do not drive!" and "check brake" car will not drive over 15 mph. Also draining has and 12 volt battery. Took it to Hyundai dealership and was told that the brake module was damaged and needed replacement. We are aware of the current abs recall. And waiting for remedy.

Abs module is damaged. Car is not operable. Dealership did diagnostic on vehicle. And stated there is an abs recall. But no remedy as of yet. Car will not operate.

Right brake light assembly melting around lightbulb and right brake light not working due to the burn. I went to multiple used auto parts store to try and buy the right brake assembly and noted multiple cars from 2011-2014 had the same issue.

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.

Incident date 07/04/2023 incident place I-405 exit wa-522 incident total engine, car system completely off, brakes won't work traveling with whole family complete car system failure, had to drive to side road hitting bushes and trees in order to get the car stopped state patrol arrived at the scene, assisted getting towing everything turned off while on freeway to direction to the two/three lane bridge had to quickly take any exit in order to avoid the freeway bridge I repeat again total engine & system failure, brakes won't work at all while system is dead.

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.

Over past 2 years, repeat alarm & message on dashboard, says, “hybrid system warning! safety stop and do not drive. ” during attempts to back vehicle from garage, brakes grind. Seemed to be on auto-stop, trying to stop the vehicle from moving. On 01/03/22, brought car to laguna niguel Hyundai. Invoice notes “caused by history codes in ahb c2112 c1102 c1237; no codes current cleared history codes and test drove vehicle no codes or lights on at this time. ” was told history codes related to something about “voltage too high” and “accelerator switch circuit [abs switch]” and “wheel rear input signal. ” on 11/28/22, brought car to laguna niguel Hyundai to address the ‘check engine light’ that was on. Service manager said “battery was not corresponding with the engine”, something about “hecu” and how it’s needed to “check brake reservoir for fluid – so I should pump it due to air bubble inside. ” on 6/12/23, was driving more than 70mph; began losing speed, down to 0 mph. Stepping on gas did nothing. Drifted toward side of road & got alarm sound and message on dashboard, “hybrid system failure. ” terrified. No control of vehicle, 4 passengers, stranded. Towed to la quinta. Notes on Hyundai la quinta invoice: “verified customer concern scanned codes p1b25 high voltage path fault; p1b77 high voltage precharge fault; power relay assembly faluty safety plug assembly are faulty. ” notes also said battery replacement: battery failed test caused by battery failed load test. On 7/31, “hybrid warning message” returned. Alarm sound, grinding brakes – car undriveable. Towed for service. Invoice: “caused by low battery state of health 53%. Recharge battery to 100% and clear dtc and road test. ” while 7/31 work was covered under warranty, felt unsafe. Why battery health poor, when it was replaced 6 weeks before? then came 8/30. Car disabled. Alarm sound & message says, “hybrid system warning! safety stop and do not drive. ” service manager said “hydraulic power unit failure”.

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 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.

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 up.

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. .

The contact owned 2014 Hyundai Sonata. The contact stated there was play in the steering wheel while driving at various speeds. The vehicle was taken to the dealer where an unknown repair was completed. Additionally, the contact stated that the vehicle made abnormal sounds while driving. The vehicle was taken to the dealer where it was diagnosed that there were metal shavings in the engine oil. The contact stated while driving 10 mph, the steering wheel loosened up inadvertently and she lost control of the vehicle. The contact depressed the brake pedal but the vehicle but failed to respond, causing the vehicle to crash into two occupied vehicles. The air bags deployed. The contact sustained a seat belt mark, soreness on the neck and shoulders. The contact also sustained numbness on the right hand. The contact later sought medical assistance. The occupants of the other vehicle did not sustain any injuries. A police report was filed. The vehicle was towed to a tow lot, where it was awaiting to be totaled. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 2,000.

I was driving home from work one afternoon on a two lane highway. All of a sudden a warning on the dash popped saying "hybrid system failure pull over immediately" and the car started beeping loudly. I lost engine power, brakes and steering. . . . . I'm lucky to be alive today. No one was on the road so I didn't get rear ended when the car came to a complete stop. I tried to restart the vehicle numerous times, however when I would shift into drive the car simply wouldn't move. I put it in neutral and pushed it to the side of the road and called a tow truck. Dealership maintenance quoted me around 8k to replace some of the hybrid system but it seemed they didn't even know what was wrong with it. The car is 8 years old with around 132,000 miles on it. I expected it to last a longer. I'm amazed reading so many other entries with the same hybrid system failure and surprised Hyundai hasn't killed someone yet with this faulty design. If I had been on the interstate portion of my commute I would be dead. Don't buy these cars if you value your own wellbeing or care about any of your loved ones.

I was driving on the highway in 70mph traffic and the car’s dash board alarm sounded with the following warning sign on the dash board: “hybrid system warning, safely stop. Do not drive”. The car seemed to have put itself in neutral without warning. I then pulled over to the side of the highway. I turned the car off and let it rest for about 5 minutes. I attempted to restart the car but the car would not start. All of the lights were on on the dash board and the hybrid system warning came back on. I could not let the windows back up or close the sunroof. I called a tow truck attempting to get a jump start but that did not work and I had to eventually get the car towed off the highway after sitting there with my children for 2 hours. This is very dangerous and has never happened before.

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.

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.

Brake light illuminated & brake pedal travelled farther down affecting stopping of vehicle. Abs hydraulic control unit is leaking brake fluid. Repair shop confirmed leak.

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.

While driving the warning in my dash appeared check brake hybrid system warning safely stop and do not drive. The front brakes sounded like they were rubbing against my tire. I stopped the car. Pushed emergency brake off and on (I’ve never had to use this before) turned car back on and it stopped. I’m worried it will happen again.

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.

Went to start my car-ignition locked,brakes are locked along with steering wheel. Having a tow company to get my car to auto mechanic to figure out the problem. Worked fine day before-has been parked in driveway for about 13 hours prior,-no messages appeared -this is the first time ever happened.

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.

What seems to be random and without provocation, the car will sound a beeping alarm that only sounds on the interior, it will deactivate the accelerator (basically puts the car in neutral), and will display a warning message that reads "hybrid system warning! safely stop and do not drive. Check brake". No matter what speed the car is traveling at, it can undergo this problem. If brakes are applied during this issue, it will sound as if the brakes are grinding and are not functioning properly. The issue can only be resolved by putting the vehicle in park, turning off the vehicle, and restarting it. If this is done, the car is back to 'normal' function. It has certainly been a safety hazard as it has done it multiple times in bumper to bumper traffic while traveling at higher rates of speed, and the car stalls out in the middle of the freeway. The Hyundai service department has found no issue after running diagnostics, and says there is nothing that can be done to remedy the issue overall. I would estimate this exact issue has occurred approximately 20 times, periodically, over the last 6 months.

My vehicle didn't pass safety inspection due to the brakes going all the way to the floor when pressed. Hyundai case number #16939771 was created and it was taken to tony Hyundai in waipio hawaii to be serviced. The active hydraulic booster was found faulty and replaced they stated all was fine but pedal will still touch the floor and brake sensitivity is extremely high causing full onset of brakes while driving at freeway speeds. This is a safety hazard and has nearly cause me to lose control at high speeds several times. I am unable to drive this vehicle on the freeway.

Tl- the contact owns a 2014 Hyundai the contact stated that while driving approximately 15 mph the vehicle would not immediately stop when pressing the brake pedal and the engine began to loose automotive power. Moments later smoke and flames were present coming from under the hood of the vehicle. Water was used to extinquish the flames. The cause of the failure was not determined. The local dealer five star Hyundai 650 russell pkwy, warner robins, GA 31088 was notified of the failure. The manufacturer was not yet contacted. The failure mileage was unknown.
