I drove my car from Chicago to atlanta and had no lights on the dashboard. I took the car to get an oil change and they reported no leaks and the car was good to go. Not even 30 mins after my car oil light came on, started making noises, and started smoking. My boyfriend pulled over to look under hood and seen oil in some areas and on the ground. We got it towed to two different mechanics and back to express oil change and was told it's a hole at the bottom of my car.

Started hearing a knocking sound in engine compartment, while driving down highway, slowed car down to 40 M.P.H., that's when the engine completely shut off and wouldn't restarted, was able to steer and coast car out of traffic.

The engine was replaced in 2018 on our 2012 Sonata hybrid under warranty due to contamination. Mileage was 82, ,895. On 5/9/2020 while driving heard loud knocking/tapping noise (exactly like last time) along with strong smell of something burning and engine light came on. Noise continued to get louder so pulled over and had car towed to Hyundai dealer in pensacola, fl. We were told the engine would not be covered under warranty and cost to us would be appox. $5,500 for a used engine with 98,000 miles on it. We now have 107,000 miles which is appox. 24,000 on the new engine. Upon investigation we found that 470,000 2011 & 2012 Sonatas were recalled on Sept. 2, 2015 after NHTSA raised the issue of engine noise and problems. It replaced engines and increased the warranty to 10 yrs or 120,000 miles. In January 2019 100,000 of these same engines were recalled again due to damaged fuel lines caused when the engines were replaced during previous recalls. Hyundai has declined our request for this to be covered under warranty because this is a hybrid. Other Sonata hybrid owners have had the same problem. We faithfully take our car to the dealer for any problems and oil changes and have all documentation if needed. We would very much appreciate any assistance you can give us. Thank you.

After having to have my engine replaced due to my crank shaft getting clogged with metal pieces on the highway and destroying the engine. I've been having issues with the replacement engine feeling like it's stalling out or losing throttle either during a turn or shortly after. It's never popped and error code and only happens now and then.

Consumer stated every time I fill up my gas tank on my Sonata the dash board indicates that I have zero gas available this caused my check engine to come on its is a concern because I believe it can cause and accident on the road or the car can catch on fire this situation happens all the time when the car is in motion and when I start it as well.

I had a 2012 Hyundai Sonata I financed from prestige auto in dartmouth MA. The vehicle had 66,002 mileage. I made sure everything was up to date and fixed prior to purchasing vehicle. Long story short with all the recalls these Sonatas have engine being one of them. I stalled on the highway due to this almost causing an accident with the fear of being seriously injured and causing injury to another person due to this. I contacted Hyundai motor corporation and better buisness bureau and was forwarded to contact this. I traded in the vehicle only getting 1,500 for it when I still owed 6,698 and had to pay that out of my pocket. All of this could have been avoided if Hyundai was cooperative but instead they did nothing!! I wasn't keeping a vehicle that was unsafe and to worry if I'm going to be alive or deceased every time I'm in it.

The vehicle does not start as it doesn't recognize the key fob. My daughters and wife have been stranded on different occasions as they were not able to start the car. Something is wrong with the electrical as the engine does not recognize the key. I am scared to take the car on long trips as this happens frequently and it can take up to 20 attempts before the engine starts. Please help!!

I am contacting you regarding the following recalls, part 573 safety recall report 17V-226 and 15V-568 after visiting Hyundai dealership twice, my car still has knocking noise from the engine, and the last month my car engine caught fire

- Rolla, MO, USA

On Sunday March 29,2020, the vehicle was in motion on a city street, my wife was driving the vehicle to her daughter's house. A knocking noise from the engine and illumination of the check engine light happened. The vehicle then stalled and the engine went dead. It did not respond at all to start it. It was towed to my wife's daughter's house by a friend of mine with a strap to pull a vehicle. The distance to her house was about a quarter of a mile. The next day on 03/30/2020 I went to go check on it to see what the problem was. There was no response on the engine. On 03/31/2020 I contacted allstate, my insurance company and the vehicle was towed by a wrecker to an auto electric business. On 04/02/2020 the mechanic said I needed a new motor, the engine was locked. That same day allstate towed it to a mechanic. On 04/03/2020 the mechanic called me and said the engine was locked and not responding. He said I needed a new motor or a used one. I then left it there until I researched any recalls on this make and model. On 04/08/2020 I found a website that is autoservice. Hyundaiusa.com and it did say my wife's vehicle was affected. I request a recall on this make and model on the engine to be inspected by a Hyundai dealer. My complaint as a buyer on this vehicle is that we should have been notified of this problem of metal debris generated on the manufacturing of the engine. These engines were manufactured at Hyundai motor manufacturing Alabama.
