Just about 2 months ago i exit my vehicle after parking up. As i exit i smelled a burning smell and heard sparks so i stepped away from vehicle asap and then the horn start honking and lights flashing on own. Then the car started up by itself and started to run without me in car and keys in my hand. Police came from noise distubing and took the battery off to stop. After that i couldnt start car so had towed in shop for 5 weeks. Hot out of shop and can start now but now my a.c. and windows doesnt work because mechanic said that something keep blowing those fuses out and if he puts yhem back in then the car will go back to not starting. I am guessing this is part of the recall.

2008 hyundai sonata 6cyl dohc 3.3l / 152812 water pump went out. Replaced it. Then water ended up in the oil that got into the lifters. Ended up getting another motor. Then my A/C stopped working (didn't blow cool or cold air). Changed oil and oil filter myself along with the oil sensor ( connected to oil filter spot) that was leaking bad as long as the car was running.I was driving on the interstate, in front of a loaded 18 wheeler, driving 75 then my car jerked real hard then dropped down to 40. I had to pull over illegally to keep from getting hit by the truck. As I was catching my breath I turned the car off. When I started it back up it made a weird tick noise. Haven't heard that noise since. When I pulled off it hesitated to change gears from 2 to 3. It finally changed and did not come out of 3rd. Got it towed home. Had my moms boyfriend to check the transmission. He drove it and it was fine. Next morning started car and it sounded like a vacuum cleaner. (low volume) finally it went away. When I headed to work, it hesitated at first. The vacuum noise came back and was louder. Then I sped up to 50, it hard jerked again, and stayed in 3rd gear. As I went further loss power in inside lane of highway and car was smoking under the hood. Like it didn't know I was pushing the gas pedal. Started shaking at around 20 miles an hour. Pulled over and check engine light came on. Called a friend to pull me back home. It was reversing fine but would not go forward. So I changed the accelerator pedal sensor (whole pedal) that wasn't the problem. So then I changed the entire fuel pump/ injector. Still have all parts by the way. That wasn't the problem either. Put it on the machine and it gave a code for ECM and oxygen sensor. Esc light came on as well as TPMS, when I started the car. I could move forward but it was like I wasn't. This all started in february 2019

Oil leaks from front valve cover gasket drips onto the alternator causes electrical system to shut down causing engine to shut down in traffic while in motion

I have the 3.3l v6 engine that is also in two other vehicles made by hyndai. Both of those vehicles have been recalled due to the fact that the engine leaks oil from a faulty gasket and drips onto the altenator. This causes the alternator to fail prematurely and often without warning. I am on my third one now and it is showing signs of failure. This can be extremely dangerous on the freeway when the vehicle all of a sudden loses all electrical power. This scenario has happened to me twice now. No headlights, no dashboard indicators, no brake lights, no turn signals. At 70mph this creates an extremely dangerous scenario.

Car will not start. It's not battery related. I've found several complaints from sonata owners of model years 2006-08. People have come to find out that it's ignition switch related. My car was parked, it has a brand new battery in it.

I have a 2008 hyundai sonata and I have well maintained my vehicle but one day I hear a small ticking noise I took it to the dealership and they said it was the spark plugs so I got the full tune up. The very next day the car didnt want to start. Ive tried everything but nothing seems to work. I also did research and a few others were having the same exact symptoms in their cars. Also lots of people were complaining about the 2011 hyundai sonatas also. I also found out that they use the same engines for the 2008 I think we alll should get a fair play
