general problems of the 2012 Hyundai Sonata - part 2

Hybrid system warning – safely stop and do not drive notification notification has been going on for two weeks and no resolution has been provided. No error codes show up but I lose control of the vehicle.

Came home saw that the break lights were on in my Sonata. Tapped the brake pedal, they went off. Came home the next day same thing. I found a re call (google) for stuck brake lights. 2011 - 2012 Sonatas. I purchased the car used, and was informed that everything is working and in order. I'm just curios if there were any other reports concerning this matter?.

Approximately a month ago I notice that my passenger side low beam head light was not working on my 2012 Hyundai Sonata so I purchased a replacement h7 halogen bulb thinking it was simply a burned out bulb. I replace the bulb with the new bulb only to find the low beam was still not working. I tried the new bulb in the drivers side to rule out a bad new bulb. The bulb worked fine in the drivers side. I also inspected the connector found no obvious problem. So far I have not been able to get the passenger side working so I did some on line research and found that this is not an uncommon problem on Hyundai vehicles and particularly with the Sonata. It appears that this is a wiring or computer issue not easily resolved. I believe this is a significant safety issue that Hyundai should repair at no cost.

My vehicle is experiencing several recall issues. The seat belt in driver seat randomly pops unlocked which is very dangerous while driving, the headlights and brakes lights go out once a month due to some electrical issues with the vehicle, the tire bearing clocks when the vehicle is turning.

Car completely shut down suddenly and spontaneously without any warning while my husband and I were driving on a very busy major highway at night. We were unable to do anything to control the car and could have died, been seriously injured, or caused death or injury to other drivers. We were then towed off of the highway after calling for help. We don’t know firsthand exactly what failed. We were aware of our engine burning oil and had been to huffines Hyundai multiple times previously for an oil consumption test at their recommendation. Upon completion of this test process no solutions for repair were offered, and we were never warned of any danger in driving it. We have found out via our own research that our car has a defective engine. This specific engine has been the subject of at least one class action lawsuit and Hyundai is well aware of its dangers. We have been denied an engine replacement by Hyundai as they are claiming negligence on our part as the reason for failure after we presented a substantial stack of oil change receipts. Not 100% complete, so they make this claim. These cars are death traps and people are dying because this company won’t honor their warranty. Please do something.

I have a 2012 Hyundai Sonata hybrid that has a problem with its abs module. It is overheating and causes my car to stop its brake and motor functions while driving. I contacted the dealership to get a rental or replacement in the meantime and they told me there is nothing they can do and to drive with caution. I called the manufacturer to get a rental for the meantime and they told me the same thing. I have looked on the recall documents and it says they should give me a vehicle in the meantime if it is unsafe to drive. Please, I don't even want the car at this point because of all the problems with it and with my dissatisfaction with customer service from any Hyundai business. But if I could just get a car that is safe to drive while I wait for the recall to have a remedy , I would take that.

The break light don’t want to turn off seat belts don’t latch.

The headlights and rear break lights keep going out, we have changed the bulbs multiple times and they keep burning out and not within months it happens within weeks the bulbs completely burn out which has caused us to be stopped by police and given warnings. The headlights look very dim when on which as well have been changed but still give a dim look. The engine has given out, the last time driving the vehicle was a 60 mile road which it lost velocity momentum and the engine light turned on then it completely shut off almost crashing into a light post.

I recently purchased a Hyundai Sonata hybrid with 132k miles on it and it has been driving fine for at least two weeks until a few days back the car has been displaying a recurring alarm on the dashboard telling " hybrid system warming! safely stop and do not drive " now as soon as I turn on the vehicle the alarm comes on immediately. It's been a week since the car is technically inoperable because if I attempt to drive the car it makes this horrible grinding sound which is terrifying considering if I drive like this it would probably cause more damage to the car, and I have look for information on this issue and have found many of these cases over the years that I can relate to but unfortunately there's no a recall of this problem. I'm taking the car to the dealership soon but I don't have any hopes that they will find a permanent fix for this since nobody has apparently. I'm just trying find some help with this issue. So far I just have lots of regrets about this purchase and just hoping I can find some help with this matter.

Hybrid system malfunction. The "hybrid system warning! safely stop and do not drive" appeared on the vehicle dashboard. While traveling on the highway or in town the vehicle will want to slow down then stop. The dealership's (wyatt johnson Hyundai) clarksville, TN, maintenance tech have troubleshot the vehicle. Since my daughter and I have owned the vehicle, it has been seen by the dealer a few times during this time a transmission replacement was completed for the hybrid system malfunction, which did not solve the problem and I had to pay out almost $6,000. Still, same issue arises and also, I was told by another tech that the transmission is sealed and should not have been opened. The only thing we heard from the dealer(wyatt johnson Hyundai) was to come and pick up the car. When my son-n-law went to pick up the vehicle, the engine was still torn apart. They said they would fix it and then let us know when it is ready to be picked up. We have not heard anything from the dealer (wyatt johnson Hyundai) at all, assuming they are still working on it. Until, we received a letter from express auto the the vehicle was towed and reported abandoned. So, I drove to clarksville, TN and trailered the vehicle back to las vegas, nv to have the Hyundai techs here diagnose the vehicle.

Power steering loses power and window between speedometer and tach goes blank. Car keeps running but no power steering and cannot take out of park. Must restart the car to solve issue. Happened several times while at idle, in park. Happened once while in drive, at idle while stopped, and was able to drive forward when I discovered no power steering. Concerned it could happen while driving.

There is a recall of our 2012 Hyundai Sonata but Hyundai never informed us of the recall. Https://autoservice. Hyundaiusa. Com/campaign132/sitecontents/english/customerletters/site_97_page_1530_customerletter1. Pdf#pdfjs. Action=download our car qulifies for the recall but Hyundai does not want to do anything about it. Our car experienced engine knocking and we took it to an independent repair shop. The repair shop infomred us about the recall but Hyundai never did. The recall is because there is a defect in the engine in which friction caused by metal bits burned up the oil. The low level of oil causes the knocking. The repair shop filled our car engine with oil. We took the car to a Hyundai dealership but they refuse to do the repairs unless the engine is knocking even though the recall letter admits there is a potential safety issue if the engine is not replaced.

I was driving on a busy street when all of a sudden. My car reduce speed hesitated there was a pull over safely and don't drive this vehicle warning message every light on the dash came on and shut off in the middle of a busy street. Thank god I didnt get hit didn't get the chance to pull over the car just shut off. The whole car died I had to have it towed way I tried changing 12 v battery to a brand new one still didn't work. I've had it towed to Hyundai dealer. What is wrong with this car? still don't kno this happened in September of 2022 took it 2 different Hyundai dealerships. As I've been researching this is happening to a lot of people. With the same make a model car. I talk to corporate. They can't help me with anything because it's over a 150000 miles. You would think that they would help with some of the cause being the fact that is happening to all of the hybrid cars.

Brake lights keep exploding.

Check hybrid system keeps appearing on the dash, forcing me to have to pull over and stop the car. Dealer can’t fix it due to the code being intermittent.

I was on the expressway and car hesitated and jerked while speed began to increase followed by hybrid warning system alert. (pull over and stop the vehicle) with a flashing ready light. Could have caused a major accident with loss of life as there was no place to safely pull over. Warning lights came in immediately after the cat jerked.

What component or system failed or malfunctioned, and is it available for inspection upon request?: vehicle went into limp mode on highway (June 7th 2022). The next day, the vehicle would not start, despite battery replacement. How was your safety or the safety of others put at risk? when in limp mode, car would not accelerate. My vehicle could have been hit by another vehicle due to the sudden, unexpected decline in speed; has the problem been reproduced or confirmed by a dealer or independent service center? vehicle was towed to the Hyundai dealership the evening of June 10, 2022. I was informed by Hyundai that it would take 2 to 3 weeks before they could even look at my vehicle. Vehicle has not been diagnosed yet. It is still at Hyundai as of today, June 22, 2022. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? the vehicle is currently awaiting diagnosis by Hyundai. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? the vehicle went into limp mode. The next day it would not start.

The brake pedal stopper pad deteriorated, allowing the brake light switch plunger to remain extended when the brake pedal was released. This kept my break lights on even when the car was turned off, which lead to issues with my accelerator randomly giving out while I was on the road, and my traction control forced off.

Tail light sockets overheats causing bulb to become stuck and whole tail light assembly needs replacement.

The vehicle had the engine replaced under Hyundai recall. What a fiasco. Within 6 months the fuel gauge starts intermittently work. Then the vehicle completely dies, diagnosis calls to have fuel pump replaced. Next 3 months the vehicle while driving losses power having to pull over to the side of the road. Thank god vehicle started and able to drive home, while the vehicle would loose power, then regaining it once took foot off gas pedal and applying pressure to again. That night find the rear brake light illuminated, went out stepped on brake pedal and went off. Another time console light would illuminate while driving no reasoning. The vehicle lastly killed the battery in the driveway. Had aaa tow to mechanic who now states the alternator needs to be replaced. After a few day not hearing back from mechanic, I call. He stating now the vehicle has electrical problems and it takes time. I will keep you posted. Hyundai has many major issues and should be held accountable, its a safety issue to the driver and general public.

As I was driving on the highway, my car engine stalled and all the interior dashboard lights came on. I was unable to accelerate although all other features of my car worked (steering, brakes, radio, bluetooth, etc. . . ). I was barely able to get off the highway safely as the highway I was on had no shoulder that was safely accessible. Luckily, I was in the far right lane already which allowed me to exit the highway. I was just barely able to exit the highway and move to the middle and far right lane of the service road before my car came to a complete stop. I attempted to turn my car off and back on without success. At this point, I could start to smell burning of something and knew I needed to exit the car immediately, however, I was unable to do so due to traffic on the driver side of my car. I noticed smoke coming from my engine which prompted to me to jump out of the car without continuing to pay attention to the traffic that was passing me. I called 911 to alert them of my car impeding traffic, potentially causing another wreck, and the potential that my car may be on fire. After making those statements to dispatch, flames shot forward from my hood and I was able to move away from my car. The fire department arrived on scene but not before the flames had reached 12+ feet as they were taller than the fire truck. The firefighters were able to put out the flames. My car engine was completely melted from the fire. At this point, the dealership, insurance agent or any other representative has determined a cause of the fire or has looked at my car. No warning lights to indicate a malfunction was visible prior to the incident. No noises or engine malfunctions were noted prior to the incident.

Front and back lights keep going out. Replacing monthly. Also air bag light starting to show off and on.

It all started with the electronic system. Both of my brake lights burned, leaving huge holes in the back of my brake light bracket. Replace the whole brake assembly on both brake light fixtures, then now my horn is not working—nothing to do with the relay or fuse.

I have a 2012 Hyundai sonta. The brake lights are not working properly. I have been changing the tail light for some time now but it doesn't seem to be working. At first all lights came on and they wouldn't go off until I took the battery cable wire off. Then on another day the brake light in the back window, got stuck and the turn signal wasn't lighting up(no brake , nor turn signal lights but it showed in the car like it was working. When hitting the blinkers. I have taken it to several car shops even the dealership to have it checked out. I was told that it wasn't nothing wrong, but got stopped by police on numerous occasions cs the car didn't have bck lights. The last shop I took it to said that it was the cars electrical system. I've checked to see if there was recalls. Doesn'tshow anything. It should be recalls on this, cause that's a safety hazard. Knowing you just changed out the lights and then boom u have no lights to show your turning or just on the road period at night. This is dangerous , I've almost got rear ended by a semi n other vehicles that was behind me and I had my granddaughter in the vehicle. Please check into this for the safety of ppl like me. Thanks in advance. .

Original report: 1/28/22 to Hyundaiusa problem with car started day after alignment. First noticed (while going up driveway) pressing accelerator did nothing - press again then ok. Got out to open gate, noticed brake lights on. Later (after dark), came out and brake lights on. Driving home noticed esc light on - esc off button had no effect. I found this exact description on "carcomplaints. Com" from 2019 and it references recall #136. Next day I cranked the car, and the "esc off" indicator came on. I was then able to turn off with the esc off button. Update: 1/29/22 next day same issue with brake light. Able to reset esc light but it came back on after driving about 15 miles. I noticed that the issue with the sudden deceleration occurred while going 55 mph. It happened about 3 times in the 5 mile return trip. Releasing the accelerator pedal then pressing again provided acceleration. When I got out of the car, the brake light remained on. Update 1/30/22 the esc light reset itself automatically when I cranked the car. While warming up the car in the garage, the brake light came on and I tapped the brake to turn off. This happened 4 times. I was pulling out of a side road onto a busy road with limited sight of oncoming traffic. As I started out, the acceleration died, and a car came around the curve/hill. I managed to release the accelerator and re-apply and got out of the driver’s way – he was able to slow down enough to avoid an accident. Issue happened several times while driving to my destination. A few minutes after going inside, the car security horn started sounding. I used the remote to turn off. I went back in, and it started blowing again. I pulled the fuse for the horn from under the hood. The esc light did not come back on during this trip but the brake light did numerous times. My research found that the brake light switch has been blamed for some of these issues. But a faulty brake light switch would prevent engaging gear shift.

The lighting system on the front and back lights, tail lights and brake lights are shortaged and melts the housings thst the bulbs go in. I have had two of these cars with the same identical problems and my son has had two Sonatas and I have more people that’s having the issue as well. It’s very dangerous because the tail lights work whenever and me as the driver can’t see behind me nor the person driving behind me will know that I’m stopping. I can’t drive my vehicles at all at this present time and has made s appointment with the company, Hyundai and filed a complaint as well. Something has to be done quickly to put this on the recall list because it’s very dangerous for myself and others on the national highways.

After an oil change, my car started losing power at the gas and suddenly turned off on me while I was driving and never turned back on! when I tried turning my car back on my engine started smoking.

1#. Air . #2 not inspección 1year ago. #3 air bag lihg warning was the first day a buy tne car. Never im put interés now im know is bad in damgere.

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.

I am experiencing the exact same issues described in a previous recall of 2006 to 2007 model affecting the brake lamp switch. My brake lamps remain illuminated after release of the brake pedal, and the esc light illuminates on the dash.

The contact owns a 2012 Hyundai Sonata. The contact stated that the brake warning light was illuminated. The contact stated that the brake lights were continually illuminated. The contact called the local dealer but, vehicle was not diagnosed or repaired. The contact was concerned about a possible fire. The manufacturer was not notified of the failure. The failure mileage was approximately 56,000.

Brake and tail light continues to burn out. I have replaced bulbs and entire assembly every couple weeks and it melts the units as well as my engine stalls out and will not accelerate and does this intermittently. This puts me at risk of one of my lights catching fire or a crash due to my engine losing power on the freeway when I turn my lights on.

While I was driving, an error stating "hybrid system warning! safely stop and do not drive" popped up on my dash.

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.

Brake lights stay illuminated when car is off. Loses speed while in motion. Esc lights come on.
