Valve cover leaks onto alternator, can cause sudden power loss and premature alternator failure. I've been researching this issue and other people have had this exact thing happen. Apparently once you get the valve cover gasket fixed, it will fail again in another year or so. There is a defect either in the gasket or the valve cover mating surface. Currently my car is only at the stage of oil leaking from cover gasket and getting onto the alternator. No further failure has happened yet. My car has 67,000 miles.

The ESC off light goes on sometimes when driving and pushing the button doesn't do anything. My passenger air bag light flashes even when no one's sitting on the seat.

I first noticed the valve cover gasket leaking onto the alternator at about 121,000 miles and at 140.000 miles I had the valve cover gasket replaced, thermostat, intake plennom gasket also. And had the alternator replaced after it failed because of the oil leaking onto it at 156,092. Luckily I just drove by my mechanics garage at about 50 mph and about a mile passed his garage the car started to buck and stall and all the dash board lights were flashing along with the cd turning on and off along with the seat belt light which was flashing on and off when it was buckled for about 1 month prior to this failure. I actually made it to his garage before it shut down in his parking lot.

Takara recall. Around June of 2019 my Hyundai Sonata started messing up it started with the fuel pump then fuses and also the battery light stays dim on the dash today the break lights and dash light wouldnt go

Vehicle was taken to Hyundai because the airbag light was illuminated, and the passenger seat belt reminder light would blink when no one was in the seat. After a diagnostic test, the dealership advised this was due to a faulty airbag sensor in the passenger seat, that was part of the actual seat. The replacement seat cushion was going to cost upwards of $1200, with the installed price of over $1500! after looking at the NHTSA complaints, I saw I am not the only one who has had this problem. A quick google search also showed a plethora of other complaints in regards to this issue. There is obviously a major issue with the sensors/airbag/seat belt system in these vehicles, and I am hoping a recall will be issued. Hyundai could not tell me if this issue would affect my airbag system or not. Thank you.

When I exit my car and my headlight are turned to off position and close door, my running lights stay on. Which I have jad to chargr my battery due yo this. So er thought it was the headlamp switch. Still having the same problem. So looked up the problem and found a couple different forums stating that this is a relay problem. The biggest problem is that this relay is integrated into the fuse box. So in order fpr this problem to be fixed I am told I have to replace a fuse box. I am not the only one with thos issue. This happenes every time I exit my vechicle after driving it. This needs to be recalled. 2. my drivers side and passenger visors do not stay up. I have gotten hit in the head. This should also be on recall.

My air bag light has been on for over a year. Come to find out my air bag control module is faulty. An ase certified mechanic gracefully checked my air bag codes for free. This is now putting my life and anyone riding with me in danger seeing as none of my air bags will deploy. According to several forums I've seen, this is not a new problem. Hyundai needs to send out a recall on something that should never fail. My vehicle has never been in a collision.

April 3, 2018: Two years ago we replaced the alternator in our car. Suddenly we are having issues with the battery light and seat belt warning lights coming on and off or staying on. We went online to see if there were complaints or issues of the same kind. We find that others have complained with the oil valve and alternator problem as well as the indicator lights coming on and off or staying on. So we took the alternator out and returned it because thankfully it was still under warranty. Therefore, this is now the third alternator for our car. However, if this is an ongoing problem, we want to be part of documented cases with the same issue. As of today, the car is running fine with the newest alternator. Our frustration is with the fact that this is the second one in two years to have to be replaced because of whatever reason. Thanks...

For the second time, I have had oil leaking out of the valve cover or timing belt cover onto the alternator. So much so, that the alternator becomes soaked and "shorts out" according to a Hyundai dealer. Mechanics who have repaired this all agree that this is a hazard and public safety issue. "fire risk" and "sudden complete loss of control at highway speeds" were both mentioned. Hyundai states that my vehicle is out of warranty due to mileage and says that there is no recall for this problem despite the obvious risks that their mechanics and other mechanics mention. After very little effort in researching this problem on the internet, it immediately became obvious that this is a common recall for Hyundai concerning this engine(3.3L V6). The recalls name other Hyundai products but for some reason skip my vehicle even though two reps at Hyundai customer service state that "you are describing the exact same problem". we have spent close to $1000 on this one issue in the last year. It nearly caused my wife to be stranded on the interstate 10hrs from home. And Hyundai admits that it is an issue but because my VIN is not listed, they refuse to help fix or refund any thing that has already been spent on this manufacture defect. Again, I emphasize that this is a public safety hazard that needs to be addressed. Despite recent repair, this problem still continues. The vehicle was traveling at 70mph each time this issue occurred. I have records of repair from independent mechanics and statement from Hyundai stating this problem. This occurred at 118,000 and 132,000 miles. It seems like it occurred prior to this as well(looking for records).

When there is moisture in the air, my car battery and seat belt warning lights come on. I lose my power steering, my wipers go very slow and a belt starts to squeal. Also, after about 30 minutes, the radio stops working and all indicator lights come on. When it is raining, I am unable to use my defrost or air conditioning as well.

The contact owns a 2007 Hyundai Sonata. The contact stated that the instrument panel became inoperable and the brake lights failed without warning. The vehicle was not diagnosed or repaired. The contact mentioned that the vehicle was previously serviced per NHTSA campaign numbers: 09V122000 (services brakes, hydraulic) and 09V280000 (exterior lighting). The manufacturer was not notified of the failure. The failure mileage was 120,000.

One morning on my way to work, I placed the key in the ignition switch and tried to start the vehicle, but it would not start. I turned the key over several times and it finally started up. This happened on several different occasions whether I was at home, work, or anywhere in public. I thought it was the starter based on my experience with other vehicles and I was going to have it replaced. Then I started having issues getting into the car. I would try to unlock the driver's door with the key and it would not unlock the first time. I would have to unlock it again (essentially unlocking all of the doors) and then they would lock. I also started having issues locking the car doors from inside the car. I would press the lock switch on the driver's door and all of the doors would lock except for the driver's door. It only locks if I manually push the lock switch. I decided to research the issue so I went and read some online discussion boards. There were hundreds of people who had the same issue and I figured that perhaps it was a bad sensor so I took the car to a Hyundai dealer. I asked them to diagnose the problem and they came back and said that the electrical system needed to be replaced. They told me that eventually I would not be able to use the key and that I might not be able to get in the car or start it again because of this issue. On a separate issue, whenever it rains water gets in the trunk gate. When I lift the trunk gate up water comes running down into the trunk. I have had to lift it up one quarter, then half way, then three quarters way allowing water to run down along the track and out of the trunk gate. If I am luck only a handful of water ever makes it into the trunk.

My valve cover gasket leaked oil onto the alternator and caused it to fail prematurely. My research has uncovered many Hyundai vehicles having recalls with the same engine specs but Sonata is not covered. Why is this? why are so many consumers paying for this problem on the Sonata when other Hyundai vehicle (Santa Fe; veracruz) having identical engine setups are being recalled" I realize my Sonata is almost 10 years old but shouldn't it still be a consideration"

Same problem as described in 14V415000 Hyundai veracruz recall. While driving the ESC warning light on, then intermittent battery + seat belt indicating alternator failure, caused by leaking valve cover. Can cause sudden failure. This defect is not isolated to the veracruz and perhaps the recall should be broadened
