This morning when i drove the car to Bart station, just before i parked in the parking lot. the showboard showed "Hybrid System Warning, Safely Stop and Do Not Drive". So i stopped and parked the car in the parking space. i'm not sure what the issue is and if i still can drive it after i came back from my work. After i checked the website and found there're a lot of people have this same issue as this case. I did not see any of them have solution for it. So I believed that this is a big issue since it will cuase death if it happens in the high speed high way. please do the investigation and recall for it to save lives! appreciated in advance.

When driving in the car at any speed over 40 mph, the brake override will engage at random moments and slow the car down about 20 mph immediately. This makes the car extremely unsafe to drive especially on freeways because when going the speed limit of 60 mph, the car will suddenly slow down with no warning to me, the driver, and the car driving behind my car, also going 60 mph or more, will then have to slow down to my speed just as fast if not faster to avoid hitting the back of my car at an excessive speed. This problem first appeared around July 6th, 2021 and has been an ongoing and worsening issue since then. There is a similar recall that has been put out on other cars, but my car has not been included in that recall even though this is clearly a problem affecting my model as well. I ask that my model be added to the recall list to avoid other people possibly getting into an accident.

On 05/26/21 this vehicle was taken to crown hyundai for an engine recall and was not running. In fact, since purchased at the auction it has never ran more than 30 feet then suts off. Tech said, computer responded with a faulty wheel sensor, a dead battery, and fault ABS sensor. I picked up the car and put new battery in it, and a left rear wheel sensor and reported by hyundai. Our mechanic said take back to hyundai to reset the ABS sensor, so on06/24/21 we did return the vehicle to crown hyundai and was tolk now they could not set the sensor as the battery was the wrong type, now a code for a flap door and an allegation of the vehicle being wrecked in the front end causing door damage. My right headlight has always been loose but no damage. Now the computer says the door plap and front bumper damage is causing 30 more defaults to pop up my wrecker driver will tell you the car was not driving but would start and move until sensor shut down. Now it will not start or move and more sensors are being shown.. Service manager said ,, I cannot tell you not to fix it, but there are more codes poping up now... There is something wrong with this picture... He said he has several more hydrid's sitting in the back that also show many codes.

I was driving on the Highway and my vehicle started blinking with all of the check lights going off and it stated “hybrid system warning stop and pull over immediately”. The car seemed to continue to jerk with the gas than the brakes went off. My steering wheel would not allow my to turn and I was very close to getting into an accident. My 6 month old baby was in the car and I feared for both of our lives. Every time I turn the car on it states the same thing... please help me

On one of the first occasions, I had just exited the Lincoln tunnel when the "Hybrid System Warning Safely Pull over" came blaring along with the "Check engine" light. I safely pulled over and noticed the car would act as if it was in "neutral" when it was actually in "Drive". I shut off the car and eventually I was able to drive.

My break lights and head lights are constantly blowing out, I've had multiple repair orders to prove this & can have records pulled from my pull overs. My back up camera now has an electrical issue and will no longer come on. Also when I'm driving the gas pedal just stops working while driving!!! Very very dangerous. My car is well kept and maintained there is NO reason for these issues to be happening aside from a manufacturer issue. I know plenty of people with the same year make and model as me and they all have the same issues. There really needs to be recalls put out on these issues as they are a safety concerns and they are putting me and my children in danger every day. I wish I had researched these issues before buying a Hyundai. I WILL NEVER BUY ONE AGAIN especially if these issues do not get resolved.

When I learned my right brake light was out and upon further investigating I found that the socket for brake bulb was melted as well. I now need to replace the socket and wiring so the bulb will hopefully work properly. When I took my car in for an oil change recently, I was told the brake socket had melted the brake light assembly. Also which will now need to be replaced as well (Quoted $150 plus labor). Next thing is a little hard to explain, but short time later I was driving on freeway and my car will suddenly stop accelerating and start slowing down. Then will kick back up again like nothing happened, car didn't lose power during this. All power was sill on radio, lights ect.. The first time this happened it was so quick I didn't know what to think. Not long after that my daughter was driving this time and it did it again repeatedly will stops accelerating (on off on off on off). To the point we were slowing down quite a bit and had to put the flashers on, as suddenly as it started it stopped. Again no loss of power or steering ect. The only light that came on was my traction control light and wouldn't go off even when pressing the button. Since there wasn't any check engine light showing on instrument panel I have no clue what could be the problem. Side note I have had issues with my cruise control not wanting to work or occasionally will work. Two days later after this incident my daughter told me that all my lights we're on and doors were unlock. Car wasn't dead at that point. Turned them all the way off just in case but another day or so later car is unlocked and completely dead took a very long time to get started back up. At this point I have to disconnect the battery so that the lights won't go on and kill the battery. Outside of these issues I've had no problems with the car absolutely love my car. But am very concerned.

My passenger rear light keeps blowing. I have replaced the bulb once a week since I bought the car two years ago. I have been pulled over multiple times, thankfully I was not ticketed and was given a warning all 3 times. The light went out again so I went to change the bulb and the the whole housing unit is melted. Now I am unable to take the bulb out to change it.

The vehicle was parked. I tried to turn the car on but it didn't come on, and then I noticed it smoking under the hood. About 5 minutes later there were flames coming from under the hood and quickly spread to the rest of the car.

For 6 months I have received emergency notification "hybrid system warning! Safely stop and do not drive" also "check brakes" most recently the warning lights came on while driving 65mph and the car lost all power. Most often this occurs when the car is parked. The dealership has looked at it twice. The first time they replaced the battery to resolve the issue. The second time they were "unable to replicate the problem" and said there was nothing they could do to fix the problem. As the car lost power while on a major highway I feel it is unsafe to drive. When the warning lights are on the brakes must be fully pressed down to engage. I filed a case with hyundai but have received no response in two weeks

Head lights and tail lights consistently burn out, rear tail lamps caused melting of the assembly on both sides near where the socket goes. Rectified rear lamp issue using lower wattage leds, not a solution for this but a band aid. Car automatic locks have ceased working, fan assembly cut on and off causing failure of radiator. Buttons on steering wheel activate wrong settings often when used. High pressure fuel pump stopped functioning, only low pressure system remains. All problems listed happen intermittently either moving or stationary.

Hello. I am reaching out regarding concern as to the malfunction of my brake lights. I currently own two 2012 hyundai sonata vehicles. The lightbulbs in both vehicles go out within days of being replaced. I was advised by a hyundai technician that the casing of where the light bulbs is inserted was "melted" and needed to be replaced. I was also advised that my car was not covered under warranty and was not covered under a recall. In my research of this malfunction, I have found that this is not a individualized issue or concern that is isolated to my vehicles. In addition to causing a potential risk of a accident, I am very concerned regarding the potential of a fire due to the "melting" of the casing.

My hyundai sonata 2012 recently experienced engine seizure on a 5 lane highway in nj garden state parkway at 70 MPH without any warning what so ever.car was checked for this recall year ago and supposedly software was installed to notify if engine was to fail. There was no warning! Dealer confirmed the engine died and is covered under the recall. I also had mentioned concern about the noise under the car. They replaced the engine & serpentine belt and told me to come back in 3 days as it was too early to do the inspection. When I got the car back the noise was still under the car, the tire light came on, back door lock stopped working and AC stopped working I called back and they told me $1500 worth of work to pass inspection. 3 days earlier they said the car was good to pass. Including continental tires that hyundais horrible suspension ruined at 16k miles(tire warranty 70k miles) and both sway bars and sway bar link. Which means I could have rolled the car at any curve.axles were changed twice on this car as they told me " manufactory faulty" axles they put on and other suspension parts. Tires were rotated and aligned by them! If that's not good enough person working on my car damaged both of my front doors when letting the car off the lift.then the dealer tried to cover up the damage and sign me the car back! Car has some serious electrical issues with interior/exterior. Lights melting, bulbs burning and now the car doors locks. Better yet new recall says if you had your engine replaced you are in a danger of the fire.how am I supposed to trust this "certified dealer" ? + the other 8 recalls and class actions about this car- hyundai needs to be forced to buy back these all of these cars. Not only is that not safe for me its also not safe for other drivers! I've also been without my car for about a month at this point.

Multiple parts have been replaced on my front end from what mechanics thought were the problem but my wheel still sticks/pull to the left while driving even after multiple front end work and alignments. Also, I've replaced head lights, tail lights, breaks and reverse lights numerous times because something keeps blowing them. When I press the volume button on the steering it changes the screen on the radio. I'm assuming it's something with wiring malfunctioning. The cruise control on the wheel doesn't always work as well
