Sonata Limited 2.4L

  • Automatic transmission
  • 35,000 miles


Drove about 10 minutes on the freeway without issue. Stopped and after a few minutes, restarted the engine only to have it suddenly have no power as I tried to accelerate. I was low on gas so thought oh no...but managed to limp to a station. While filling up I'd had another thought, as I had been warned the key fob battery was low. Coincidentally, I had grabbed a new battery before making my run...so while I filled up I also replaced the battery. No matter, no help as the car continued to limp home as I could eventually accelerate...it's like the throttle cable was broken. I even placed the car in neutral and tried revving the engine - no good. I'll call the dealer tomorrow, haven't a clue why this happened.

Sonata Limited V4

  • Automatic transmission
  • 73,000 miles

It came on around 73,000 miles and we took to our mechanic. He ran the codes then cleaned the sensors. We picked it up and less than 100 miles later it came back on. It caused issues accelerating, stopping, it runs high on the RPM. It doesn't seem to ever go down to like rest. It is always like revving.

Sonata 2.0t

  • Automatic transmission
  • 42,000 miles


I was driving my 2015 Sonata 2.0T Ultimate when the car began to vibrate and the check engine light came on at 42,000 miles. The car started sputtering, loss power, and the Hyundai bluelink system came on stating that something was wrong with the engine. I made an appointment, took the car in and the service department said that one of the spark plugs was burnt and fouled. They replaced the plugs and also asked what type of gas did I use. I stated, the same as everyone else and what is recommended by Hyundai. The manual states they should be changed at 45,000 miles. Sounds like they need to adjust this considering I had this issue below 45,000 miles.

Sonata 2.0t

  • Automatic transmission
  • 66,000 miles

I was driving the car home from work when the check engine light came on and the car began sputtering. This also happened last year and I reported that issue as well. It happened 13 months ago. I took the car to the dealer on Friday for a Saturday service and was then told on Saturday that it would cost $160 for a diagnostic which was interesting when I was already told when I dropped the car off that my car sent the codes via bluelink to the dealer which were same codes (misfire) that happened last year with the same issue.

I assumed the issue was the spark plugs (happened before) and after two days of having the car, they tell me, it was your spark plugs again (no surprise) and they told me I am using bad gas because they detected a bit of water in the fuel. Interesting because I use the same fuel everyone else uses in my house and neighborhood and it seems to work for my 2000 Toyota Avalon with over 370,000 miles on it.

The owners manual recommends changing spark plugs every 45,000 miles so how can this be the 2nd time I have changed the plugs and the vehicle only has 66,000 miles on it? Something is fishy with the 2015 Hyundai 2.0T engines. Waiting to find out if I have to cover this expense but not happy considering I have a feeling this will always be an issue with this car.

Sonata 2.4L

  • Automatic transmission
  • 56,000 miles

Engine and oil light came on and car started sputtering. I took the car to Meiniki and the mechanic said that

the oil was, "bone dry". The oil or engine light never came on prior to this. He noted that two codes were found on the computer.

I had them fill it with oil. Evenything drove fine until the following day on my way to work. Driving at 60mph the engine seized car still moving. I pulled over on the side of the road. I lifted the hood and there was smoke coming from the engine. I had it towed to my local dealership. After getting the run around for almost 2 weeks after getting my maintanace records from MD Hyundai, they said the failure was due to lack of maintenance. and my warranty would not cover this. Then they told me the codes were deleted when engine stopped HMM?

First of all this is a serious issue if I were to keep driving it the way it is. The part is on back order. They want me to leave the car with no timetable. Car is dumping fuel, sputtering, giving multiple codes. Rough idle the list goes on and on. Best warranty yeah right! Customer service is a joke.

Sonata Limited V4

  • Automatic transmission
  • 16,550 miles

I have a 2015 Hyundai Sonata Limited that I purchased in September of 2014, a brand new beautiful vehicle, well, my car is just a year old and I have had to take it the shop (2) for the same thing, while sitting at a traffic light my car just shut off, so I waited and it started back up, I called and explained to Cocoa Hyundai service they said bring it in they ran every test and said it was fine and sent me on my way.

Well no later than (3) weeks later I was driving home from work and my car jerked engine light and skid light came on and the car shut down, I waited it started back up moved a inch and it shut off again the RMP's went crazy I called Cocoa Hyundai service department took it in they ran every test called the Hyundai Tech he had them run different test, they called me the next day and said that they can't find nothing wrong with my car REALLY...I am in fear of driving my car because it just shuts off in the middle of the road and Hyundai seems to think that this is normal. I pray that nothing happens to me on my travels. I am really beginning to have my doubts about this vehicle.

  • Automatic transmission

I bought this car in March of this year 2015- on June 29,2015- the engine died on a residential road. I thank God for my life because if I was on a beltway or highway I would not be here sharing this story about this car. I had it towed to the dealer where I bought it from they are telling me that they don't have nothing to with the problem that am experiencing. I don't feel save anymore. I am afraid to get the car back. The car is still at the dealer and the service manager can only tell me they will let me know what exactly is the problem with it. I want to sell the car back to them because is car is not safe. There is a huge problem with the engine. The dealer is trying to replace the engine but even if they do, I don't wanted back. I don't feel safe at all.

I was riding down the street with my daughter. Approx 40mph. All of a sudden my car slows down in traffic, my heart stopped. It started stuttering & back firing.. The check engine light & skid light came on.. I called, of course they we're closed... Took it in the next morning & less than 2 hrs they called & said it was a mere computer glitch. Thinking about trading it in. For future problems to be avoided... Don't want to be riding on the interstate & this occurs.

Never would have thought a brand new car would have such a problem... Wow!!!!

Sonata 2.4L

  • Automatic transmission
  • 2,890 miles

This is my second 2015 Sonata since July 2014. The first vehicle was taken back by Hyundai for basically the same problems I now have with my new 2015 Sonata, 2890 miles. When driving anywhere from 40 to 65 mph and without warning the vehicle decelerates by itself to about 20mph and the check engine light and the anti skid light comes on. The engine appears to lose compression. According to what I was told this protects the engine!!!!!!! What about the driver and passenger????

You have to pull off the road and turn the vehicle off. You have to wait 3/4 minutes before you can restart the vehicle, this is supposedly to reboot the computer, however the check engine light and the anti skid light stay on. On my first vehicle they replaced the computer system 2 times (similar mileage) now on this vehicle the check engine light goes off after several hours by itself so it's difficult for the dealer to confirm my complaint. There is a MAJOR safety concern that you don't know when and where this vehicle will basically stop working, especially at high speeds. Anyone has similar issues please post.

Sonata Limited

  • Automatic transmission
  • 3,100 miles

Check engine light came on and then the car would ramp up on it's own. Took to the dealer and diagnosis the problem with the speed sensor not a major repair, you would think. My car has been setting at the dealer for the past 3 1/2 weeks, the part is not available. I have to call for an update each week to see if the part has come in or coming in. I was told on Monday the parts are coming in this week, called back today to see when the car would be done. Sorry we didn't get the part, I have to call the Hyundai warehouse to find out why the part didn't come in, the haven't called back to tell me (no surprise). I was told 3 other cars are sitting there also waiting for the same part. I was giving a loaner car to use, but I'm paying for a car with all the bells and whistles and my loaner car does not have these options. I wish now that I would have bought the Honda Accord.

Sonata Liimited 2.4L

  • Automatic transmission
  • 3,300 miles

After a day in parking lot the car started with check engine light on, and fairly high RPM when in idle. The check engine light did not go away and stayed on all time. The engine started running erratically. Sometimes when idling in an intersection the RPM goes up all of a sudden and the car starts moving forward, and only stronger push on brakes stops it from running into the vehicle ahead. When on highway the car lacks power, even if the gas pedal is depressed all the way into the floor.

I took it to the dealer where I bought it from. At first they just reset the check light and said everything is OK, the check light was "inactive". I drove 2 miles from the dealer and the check light came back with all the other symptoms I described above. I turned around, brought it back to the dealer and left the engine running so they won't say the light is "inactive". The car stayed with the dealer for 2 weeks. They identified the problem as "cam cover leaking" which makes the oil come through the oil seal "making the motor do weird things". These are the quotes from the paper sheet I got from the dealer. So they replaced the cam cover with the new one. I was driving a loaner for 2 weeks while they were doing it. 2 weeks later they said I can pick up my car which.

Two days and 240 miles after the repair the same problem again - check engine light and engine running erratically. This is the 2015 car which had less than 4,000 miles on it. I wish I did not buy Hyundai

My car, Sonata 2015 only 2 1/2 months old, it's Thanksgiving and can't go out town. They gave me a renter car but it's dirty inside, don't have the things I'm use to so my Thanksgiving is at home and not with my family. This is twice my car has gone to the shop, very unhappy.

So this is my aunt's car. She was driving with cruise control on tonight on the way home and the engine bogged down a lot and then revved up quite a bit more than normal. Then the engine light came on and she said it just wasn't driving right. She couldn't find a ride home so drove it home and parked it. Is calling the car lot tomorrow to make them fix it.
