2012 Hyundai Sonata: headlights failing or too dim

Filed Jan 13, 2025 · Electrical, Fuel system · VA

I’ve been having issues with my Gas Gauge not recognizing how much gas I have in my car. I can fill my tank up, and the gas light constantly stays on. I’ve been looking online and came across other Hyundai owners having the same problem. I also have been having what seems to be an electrical issue where my passenger door, does not open and it’s intermittent which also seems to be connected to why my car ceiling light won’t turn on all the time. Lastly, I have to constantly change the head light bulbs and the break light bulb. I’ve owned my car for 3 1/2 years now, and I shouldn’t have to keep having to put money into it when it seems to be a known issue.

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!

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.

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.

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.

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.
