Was driving in reverse out of garage and abs brakes were applied like I hit a patch of ice stopping the car. Released when applied pressure to brake. Then while on highway going 60 miles an hour the emergency brake system went on for no reason applying pressure and red light came on the dash with a left facing arrow. System released within a few seconds but scared me and I still have to drive this car on highway.

In October of 2023, I was driving my 2012 Hyundai Sonata hybrid to the laundry mat about a quarter of a mile from my home. I stopped at a stop light and all of a sudden, a warning sound burst from my dasher board. The message stated, "hybrid warning-do not drive: check brakes". The brakes completely stopped working, the pedal was to the floor and the accelerator was stalling. After managing to get the vehicle back to my home, naturally I went to the dealership (langdale Hyundai of valdosta) and informed them of the issue. They informed me there was no issue, charged me for a diagnostic and sent me on my way. Once I provided proof of my car stopping mid-drive, they began to check wiring and such. What they told me the issue was is a hydraulic power unit. I had it replaced, still the same issue "check brakes". I only have 116k miles on this car, bought it with 72k in 2021, so I haven't driven it much. It spent 8 months in Hyundai dealership in holiday, FL for a brand-new hybrid battery in 2022. I have been looking online for anyone that knows more about this issue so I can get it resolved. It turns out there are thousands of people who are just like me. I believe this is indeed a recall issue. I believe this is an issue is an emergency issue, brakes giving out while driving is an issue that needs to be addressed. This has been happening for years, and Hyundai has not done one thing on it. It's happening with newer vehicles as well as older. Langdale Hyundai of valdosta was not much of a help at all, to be honest, I don't trust their workers at all. I believe they do nothing and charge customers for the max that they can.

After starting, got a warning stating check hybrid braking, do not drive. When going forward, brake pedal went to floor, heard heavy grinding noise and vehicle stopped accelerating. Had to use the emergency brakes to avoid an accident. Hyundai says they can’t find a problem. Now I can’t even drive it back to the dealer! did an internet search and many other hybrid owners have reported the same issue. I just want to have Hyundai buy the car back at this point. It only has a little over 50,000 miles on it.

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.

I was driving I seen smoke then full flames on my windshield and I tried to stop and put my car in park to get out but my brakes stopped working and I couldn’t get the gear in park so I opened the driver door and had to jump out of the car . I had an engine replacement a year before for it being recalled and police and firefighters were on scene after incident.

My engine block or engine has a hole in it. All of my oil came out and my vehicle shut off. My brakes as well is not hard when pressed on, so I would have to pump it till it hardened. My safety and others safety was at risk while I was driving because my vehicle was not coming to a complete stop which could have resulted in a serious or fatal accident. As well as my engine block blowing making all the oil in my vehicle leak all on the road while driving on a busy road. Yes the problem has been confirmed but I was told that my car does not fall under the cars listed with the same issue on the recall list. No it has not been inspected by the manufacturer or police or insurance rep because I am being told I have to pay out of pocket and I am not able to afford the prices being told to me for an issue that I have not caused. There were no warning lamps or anything prior to this incident. I have went to many different mechanics for a diagnostic for my vehicle but they all say my vehicle is fine or they do not know what I am talking about.

Active hydraulic booster failed while driving. 2012 with 114,000 miles on it. Brand new engine and transmission installed from prior recalls. Hyundai dealership said it was covered under anything and would cost $5k to get fixed.

On November 4, 2024 while coming to a stop in traffic, the brake pedal went to the floor without any warning. Just prior to using the brakes, there was no feeling of softness in the pedal, and no indication a low pedal situation, and there was no indicator of pending brake failure. The brake light indicator only lit when the brake pedal went to the floor. I was fortunate that I did not rear end the vehicle ahead, or more seriously had there been a jay walker, because I quickly pumped the brake pedal with what little braking I had while shifting the automatic transmission to second gear. I was able to slowly drive ten miles home in second gear while using the hand brakes. Eom.

There is no lights at all on the brake lights but the brake light in the back window stays on all the time the dim head light only lets one side work.

I was driving as normal and twice about 3 min apart from each other my car went into emergency braking and stopped sudden. No red lights no warnings nothing. Also periodically my car dashboard lights will come on while driving filtering through all the hazard checks. Sometimes it stays on and sometimes it don't. Eventually dash goes back normal. Again all with no warning. Very scary.

I was driving down the street I went to show down by hitting my brakes they wouldn't slow down the vehicle then the car caught fire.

The driver side seat belt wont click and stay in almost half the time I drive my car… after reading other complaints its looking like this is a common thing. Within the past year ive noticed lots of times that when im going to lock my car with my fob, it wont lock and its because the passenger side lock button on the inside of door is in a stuck between lock/unlock position… resulting in me having to lean over to manually unlock the door even when I’ve unlocked my car with both the fob and inside button… all the sudden I noticed too that my speed control will not work at all and be completely unresponsive most times. It will randomly work when I try checking it on highway. Ive had so many issues with my taillights going/burning out constantly and now my headlights have gotten really dim. Im scared to drive at night now. They are much more dimmer than a cars should look like usually. Within the past week I just noticed a random big crack in the dashboard on the passenger side as well… noticed that seems to be a common thing and concern of safety with lots of others who own and drive this same vehicle… my first thought was “what if this crack will effect the airbag and make it deploy?” the crack is literally right over and above where the airbag is… plan on trying to take my car to place on okc that did the anti-theft system software update on my car… but my car has gotten so bad when driving ill be lucky if it makes it there in one piece. My car has started to shake so bad when im driving!!! almost “jumping” at times it feels like. This car has been a pretty good car but when there are multiple complaints of the same issues that continuously keep costing us money and its not because of our doing and in fact the manufacturers faulty equipment and parts that they used to make these cars… they should most definitely be doing recalls and fixing these problems at no cost!.

I believe this is the same issue as the Hyundai recall #170 (activation of the engine management system's brake pedal override feature). While pressing the accelerator, my car will stop accelerating until I let off the gas pedal and then press it again. This is an intermittent issue and unrelated to any fuel delivery system. I confirmed it was a brake pedal issue because my brake lights would not turn off and I could shift out of park without my foot being on the brake pedal. I feel like this could be a pretty big issue for properly signally drivers behind me as well as when I’m trying to drive in heavy or speedy traffic, e. G. , merging onto or within interstate traffic.

Brake system warning, puts car in limp mode on freeway nearly causing rear end collisions.

Fault code in the automatic braking system c24020 c17410 white body paint bubbling and peeling off the car for no reason. Passenger door roof frame and trunk. Hood previously repaired.

On July 29, 2024, my 2012 Hyundai Sonata hybrid was parked in our driveway. About 10 minutes later an engine fire started that consumed the car. The local fire departmemt put out the fire but the car was totaled. The fire also destroyed a storage shed and some windows were damaged. The car was taken to the Hyundai dealer for servicing when the engine light came on on March of 2024. The car was left for a few days with the dealer. The NHTSA recall number 23v651000 was not repaired during that service call.

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.

I have had this car for 2 years (13k miles). . . . Intermittently the car stops short when backing up. This has happened at least 15-20 times, backing out of my garage. It also happened twice backing out of a parking space. The most recent incident was driving on the hwy at 70mph and the emergency brake warning light came on causing the car to swerve, stop for a few seconds. Needless to say this was very scary. I am attaching a link with the same or similar complaints: [xxx] I have been in touch with corporate. The car is currently at the dealer ship and has been for 2 weeks. They are trying to duplicate the problem, but it is so intermittent, I doubt they will find anything. I was told they have to keep it for 30 days, then. . . . I don't know what the next step is. I love this car, but no longer feel safe in it. Please advise how you can help. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

In April 2023, I purchased a 2015 Hyundai Sonata eco from carvana with 56,000 miles. By may 2023, the mileage was around 72,000. While driving from south houston to north houston on may 22nd, 2023, the car loudly popped as I exited the highway around 5:00 pm cst. I noticed smoke coming from the rear and parked in a construction zone near a convenience store. Upon inspection, the vehicle stopped working, and I saw a significant fluid leak underneath. A bystander alerted me to flames from the bottom and under the hood. I called 911, and the fire department arrived to extinguish the fire. Fortunately, there were no injuries or property damage. I later discovered that specific 2011–2015 Hyundai models had been recalled due to fire risk (NHTSA 23v-651000), but this did not include the Hyundai Sonata eco. The recall was due to the anti-lock brake system (abs) module leaking brake fluid internally, potentially causing an electrical short and leading to a fire. I have photos and videos documenting the incident. Following the incident, I filed a claim with travelers insurance, and on may 28th, 2023, the vehicle was declared a total loss. While I appreciate their offer of ~$13,000, it is insufficient to cover the remaining loan balance of approximately $17,300. I am worried about the financial impact and potential danger I face due to this malfunction. The lack of information highlights the need for better consumer education. I am now looking into options to cover the remaining loan balance, acquire a new vehicle, and, most importantly, advocate for improved driver education regarding this defect.

While I was driving after picking up my daughters from school the car start giving me a hybrid system warning and a brake message on the dash with brakes not working properly so I stop and get the car tow to my mechanic it was scary since I have my 2 daughter with me my mechanic said the problem is the hecu and needs replacement he tell me there is a recall #251 I call the dealer but they said only cover a fuse no the actual defected part that doesn't make sense I seen a lot of complain of this part going bad hopefully Hyundai do something to make right and fix the actual problem and dont put life on risk like happen to me and my daughters.

The contact owns a 2011 Hyundai Sonata. The contact stated that while her daughter was driving at approximately 80 mph, the brake pedal was depressed but was stiff and difficult to depress. The contact stated that her daughter accelerated to steer the vehicle away from slower traffic. The contact stated that her daughter depressed the accelerator pedal however, the vehicle failed to respond and started losing motive power. The contact stated that her daughter was able to steer the vehicle to the side of the road and stop the vehicle. The contact stated that the check engine and check brake and several other unknown warning lights were illuminated. The contact had the vehicle towed to an independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 120,000.

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.

Check engine light comes on, brake system malfunction warning message appears and says to pull over, vehicle goes into limp mode. Hyundai dealership says $150 to diagnose problem.

Intake camshaft, camshaft position actuator circuit and brake booster are the system that failed all in the same week. My safety is being put at risk because of the bad brake booster I almost rear end someone else. My car doesn’t accelerate has it should initially which could cause a wreck. Problems has been confirmed by independent service center. My car has been inspected by mechanics. My engine light is on and when diagnosed the codes p0011-00 & p0010-00 pop up.

I was pulled over by law enforcement due to both brake lights being out. Further investigation while changing the bulbs for the 3rd time in 1 year found the housing was deformed and plastic around the bulb housing was melted. The left light bulb was completely black and was difficult to replace the plug back into the plastic housing. The right light bulb metal piece melted into the socket and the glass part of the bulb fell off the metal piece and would not come out of the brake light assembly as if it was now to big to fit throught the hole. This bulb broke off the metal piece and fell into the brake light assembly. After using pliers to remover the broken metal piece from the bulb socket. The new bulb was placed and still could not fit in the hole it is designed to fit. Further inspection reveals the plastic housing the bulb should fit has melted and can no longer accept the new bulb or removal of the previous bulb. This is a safety hazard as the bulb and wiring gets too hot and could heat up the plastic to the point of burning the inside of the trunk. As well as continuing replacement for the bulb of which now cannot be replaced. Potenial safety risk for an accident if the brake lights cannot be replaced due to warping or melted housing. There was no warning or safety notice provided. Until I researched and found the problem has been reported by many owners of this make and model and there is even a recall that went out in January 2024 for the exact issue. I reported this to the dealer who informed me my vehicle is not apart of the recall even though my vehicle meets all requirements of the recall and extended warranty for the recall. Year, make, model, within mileage requirements and the safety issue being present. They want to charge me just to confirm the issue and possible charge for the repair.
