After Hyundai USA replaced the engine and our dealer fixed the fuel rail leak the repairing dealership messed up, we had no power, no turbo, and it sounded like the young kids’ little Scions or Toyotas with the loud pipes. The dealer is trying to soak us with a $4000 repair bill.

Update from Nov 10, 2021: We took the Sonata in to the dealer in March of 2020. Then Covid hit and there were no mechanics available to repair the car. We also were still fighting with Hyundai USA regarding responsibility for the repair costs, since we felt the problem was directly related to the shoddy repair work done by Merced Hyundai, After months of not having a car, Hyundai finally contacted us. They would take responsibility for 90% of the costs, and we would be responsible for 10% (which turned out to be $399). We paid our portion last September. So far, after more than a year, the car is performing well. We’re kind of waiting for the other shoe to drop, though, because we found out the engine that seized was NOT replaced, only rebuilt. That means it still has the defect that caused it to seize in the first place. Hopefully we will get many more years of service. We love our Sonata, but not the engine problems.

I have a 2013 Hyundai Sonata and my engine light has been on for over a year now. I contacted my local dealership and even had them to look at the car and they continue to tell me it is my fuel filter. After having my fuel cap, purge canister, and several diagnostics. My engine light is still on. I also have a problem with my car stalling when wanting to accelerate. The dealership states there is nothing wrong with the engine in my car. I am not convinced. There have been several complaints about the engines in these cars and the dealership are refusing to replace or fix them. I do not find this to be fair, especially when I have to continue paying for something I am constantly repairing.

I have a 2013 Hyundai Sonata. We purchased from Hertz rental company May 4, 2015, we also purchased a Gold Plus warranty. Few days ago I noticed that when I accelerated the car started to sputter and making a clicking noise, thinking to myself something is not right. Went online and typed in symptoms to see what could possibly be causing this to happen. I was able to hit a link that directed me to possible dirty Mass Airflow Sensors, looked at the video to see what was involved. After watching the video I learned that it was not that difficult to do, so I was wondering if this is something I could do, but I wanted to make sure that this was the problem, next morning started the car to drive to dealership noticed that the oil lamp came on briefly than turned off, first time that happened since I had the car. I was going to go in for an oil change anyways so I decided to see if there was anyway the tech could look at the MAS (Mass Airflow Sensor) to see if it was dirty while he had the hood open to change oil, figured it would be good to bring to a Hyundai dealership. I asked if one of the techs could ride with me to visually see and feel what I was talking about. Whilst driving I was able to get the car to make the noise and at that same time a puff of smoke came out the tailpipe. Make a long story short, Hyundai dealership told me that there was evidence of thick sludge in the engine had been starving for oil for a very long time, probably need to replace the engine, and that this was caused by negligence on my part, also stated that claim warranty will probably be declined, $7,000.00 cost to replace engine. What is very strange about this is not only 4 months ago I brought the car into the same dealership to get a tie rod fixed (this was covered), and a 42 point inspection was done on my vehicle, GUESS WHAT, this inspection revealed no problems of future fixes for dark sludge when oil levels were checked. How could this have been missed?

My car surged out of control hitting a building. The dealer won't even look at it and I have to wait for Hyundai to send me a package out to fill out and send back. The damage is fixed from the crash, but they are not willing to look at why the car surged!!! I am suppose to get back in my car and drive it till an independent company can look at it 6-8 weeks down the road....really???? Where does your warranty come in to place here??

I have already complained to them about the lack of acceleration. They said that it was my gas saving button. That didn't work...something is wrong with this car.
