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.

On October 18, 2019 my fuel pump broke it happened at a plaza parked and then on February 10, 2019 was involved in a car crash due to a ball joint from the front end passenger side. My ball joint broke and everything else detached it happened on the highway I was with my kids and thank god I didn't crash into a car but it was a very scary traumatic moment for all of us. I keep replacing the inner and outer tie rod, also the ball joint and now it makes sense why, it has to do with the control arm. I'm reporting this now because I looked into the safety recalls today and found so many my vehicle falls under these listings and I never received a letter stating the safety recalls to bring my car to the dealership. I have pictures taken when my car broke down, but don't have it available right now I can provide it afterwards and I had my car towed.

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.

I had been driving on the turnpike for almost an hour when I started to hear a clicking noise. I was driving about 70 mph and pressed down on the accelerator. When I did so, there was a loud bang and suddenly, smoke filled under the hood and also came out the exhaust pipe. I also saw debris flew out from under the car, looking like it was coming from the tail pipe. I pulled over and opened the hood to find oil everywhere, more smoke flooding out of the hood and bits of metal debris all over. Oil was leaking all over the side of the road. The mechanic has judged that the engine burst while I was driving it.

Oil leak from valve cover gasket dropped on alternator. Damage to alternator caused vehicle to shut off while going 60mph on an interstate. Multiple lights on the dash illuminated (including the engine and battery lights, the seat belt light started flashing), I lost power to the radio and the lights inside the car stopped working, quickly after these two issues started I lost the ability to accelerate (again, while going 60mph on an interstate). Verbatim text from complaint 14V415000 for the Hyundai veracruz (including the model year 2007)- "an unexpected failure of motive power while driving increases the risk of a crash." I believe that this recall should be expanded to other Hyundai vehicles as there are a number of other complaints online for Sonatas for multiple years, including 2007. My local dealership quoted me $1372.43 to replace the alternator, valve cover gasket, and battery (attached).

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).
