My car is a pre-owned car with currently a little over 76,000 miles. I had this car for almost 2 yrs, and my engine has died. I keep up with my oil changes every 3,000 miles. Because I'm the second owner the warranty is up to 60,000 miles. I don't understand why would my engine fall on an 2011 Sonata. Hyundai should look into this issue.

This Hyundai sonota has a push button ignition. Once the engine is started, a person can leave the vehicle with the key fob in their pocket and the engine stays running and will not shut off. This is in violation of federal motor vehicle safety standard 114. Once the key is removed from the vehicle the engine should shut off. This engine is so quiet you cannot even hear it running while in the vehicle and if someone is partially color blind you can barely see the red and green indicator. This engine will run in an idle state no matter where the key causing risk of fire, carbon monoxide poisining and death and injury to anyone near this vehicle if left running and since the car stays running once it is started anyone can walk away with the key fob in their pocket and the car stays running no matter what. There are no reminders when exiting the vehicle that the engine is running, there is no automatic shut off in the vehicle, there are no reminders in the vehicle that the engine is running. The push button starts are not only a safety threat but also can be hazard in a parking garage if the engine catches fire due to over heating it can affect all the other vehicles in a parking garage and cause even worse damage.

On sept. 3, 2015 while driving on the expressway I experienced the engine locked up and immediately pulled onto shoulder. I tried to restart the engine and the car began to smoke. Had it towed to darcy Hyundai in joliet. Hyundai informed me that the engine seized up and the starter was burned out and it was out of warranty and said to repair it with a replacement engine would be 5800 dollars and at that point I did not have the money and my credit cards were maxed out. And then I had to asked my father for advice either to repair or replace the vehicle. We decided it would be more practical to purchase a used car from car-max and because of my financial position my father had to extend himself and sign for the car. This 2011 Hyundai Sonata was also in my fathers name due to a bankruptcy.

I was traveling in PA. On route 879 and 153, at a rate of about 60 mph merging into traffic, the engine just stopped working, I almost caused an accident trying to get off the road while the merge lane was ending. This vehicle has been regularly maintained. I am being told by the mechanics that I need a whole new engine. The mechanic doesn't see why this should have happened. I understand that other people have had similar experiences, thankful no one was hurt. Opened a case with Hyundai (c8187494). The operator at Hyundai that took my information stated that she new of the lawsuit and that Hyundai was not doing anything. Someone could have been killed any assistance you can give would be appreciated.

Tl- the contact owns a. The contact stated that the keyless start functionality did not perform as intended which resulted in carbon monoxide spreading throughout the residence. When the vehicle was purchased the dealer informed the contact the keyless start system in the vehicle had an idle timer which is supposed to shut the vehicle off when idle for a period of time. The contact required medical attention and the physician diagnosed that the contact had carbon monoxide poisoning. The vehicle was not taken to be diagnosed. The contact manufacturer was not made aware of the issue. The approximate mileage for the vehicle was 10,000. Kh.

We began hearing some noises from under the hood, and scheduled to take the car in for maintenance and an oil change on Wednesday of the following week (8/18/2015 was our appointment). On 8/17/15 the car started like normal, we got back on the road, and my husband began to accelerate. It accelerated to 15mph, then stopped accelerating. The car had shut off. The lights on the dash came on, the power steering and power brakes ceased to work, and we barely made it off the road. We put it in park, took the key out, waited for a minute, and tried restarting it. It would click once, then nothing. We tried jumping it, nothing. We were told it sounded like the alternator, so had it towed to a nearby aaa shop. The following day (Monday, 8/17/15) we received a call that the engine had seized. And upon calling the dealership we bought the car from, found out that the extended warranty we purchased, had just expired at 109k miles and we were at 130k miles. We asked the aaa and the dealership to call around to get pricing on how much an engine would be. They were shocked to learn that the engine for the 2011 Hyundai Sonata is unavailable nationwide, indefinitely. This is unheard of and is what prompted me to search online to check if a seized engine was one of the many problems/recalls/mistakes made with this car, and surprisingly, it was! I truly hope the NHTSA will investigate at the very least! and recall this car!.

Hyundai is going to replace the engine under warrantee, however they only warrantee this brand new long block (engine) for 12 months or 12,000 miles instead of warranting the engine for an original 10 years or 100,000 miles. The problem is can this new engine be trusted since we don't know when the engine was originally built. Hyundai requires that all oil change records be given to dealership.

48 hours after the dealer replaced two selenodes and wiring harness (stating it could be my driving habits, but would file it under the warranty) - the vehicle starting shifting even harder than it previously had and then suddenly would not go over 25mph and the rpms were 5-6. Luckily was able to get vehicle to the dealer (I am the original owner) - and was told it now needs a new transmission. I had zero issues with my vehicle till it hit approximately 75,000 miles. I have filed two other complaints on this website regarding the other two incidents that I've had warranty work done on in the last 3 months. I expect that this vehicle will completely fall apart by the time I hit 100k and there is no longer a warranty. I am very fortunate that I did not have my 3 kids with me this last time.

The engine was sputtering and then just quit. Got it restarted long enough to get out of the roadway. Took to dealership where it was purchased. They stated there was no oil and that a new engine was needed. The oil light never came on and the temp gauge did not show the engine was running hot or anything. It just stopped running.

My wife and little kids were traveling on highway when the car lost power steering and all the lights light up on the instrumental panel. Luckily, she was able to maneuver the car to a side of the road avoiding rear-ended collision. There was no indication of any problem up until last second. It was towed away and later declared as engine seized. This car is dangerous and hazard on a road.

We were traveling at approximately 65 mph in the 2nd from right lane in heavy rush hour traffic when the engine abruptly stopped and could not be restarted. My wife had difficultly steering and braking to move to the breakdown lane from the loss of engine power. It was very fortunate that we were not hit by oncoming traffic. The car was towed to the dealer who stated that the engine had seized and needed to be replaced at great expense.

On a couple of separate incidents, the gear disappear. I was driving on d, the gear was on d, but after several miles the gear disappear. I pulled over to park the car, I put the car on reverse, but the gear was not visible. I turned the car off and turned it back on, I could see the gear then. This has happened a couple of times. A couple of weeks after this happened, the car did not start at all. The car ended up starting after it was towed to the dealership. Apart from this issue I've been at the dealership for several other issues. Starter, axles, the key ignition switch, sensors, etc. It's been very time consuming and expensive.

I was driving on the interstate at 65mph and my engine seized without warning. I drifted off of the road and contacted Hyundai roadside assistance. The car was towed to the dealership. After 3 business days of not getting any answers on the problem from the dealership they finally called me and said the engine had "sludge" and needed to be replaced. The car is a 2013 that I purchased in 10/2012 and had 45,000 miles at the time of this incident. I was informed that there was nothing else that could be done and the warranty was declined due to lack of maintenance (oil changes). I just had my oil changed the same day that this happened. I was told by the dealership that there was nothing else they could do and a used engine would cost $4,000+. I declined the service. The customer service at both Hyundai and the dealership is awful. My car is still at the dealership. This is a serious safety issue that needs to be addressed.

In the evening of the 22nd the traction control light came on and would not go away when I pressed the button also the car would have a long lag between pressing or releasing the accelerator and the car responding. The next morning when I began driving again the traction control light did not come up but when I began to accelerate and got to 20mph the car suddenly stopped accerating and the engine went idle until I released my foot from the pedle and reapplied it when it would go again with no additional issues. This pattern repeated itself each time the car dropped below 20 mph.

On 6/3/15, we were driving on the highway when car suddenly lost power. Thankfully, we were in the right lane and my husband was able to get off on to shoulder. Towed into Hyundai who stated engine had seized. Told by dot if we were in far lane we would have been dead and the shoulder we were on was actually a lane that was in use from 7 to 10 a. M and it was 10:15. To not be responsible for $10,000 bill we traded care in for another Hyundai model. Sonata was 3 years 10 months old and mileage was 41567.

On may 29, 2015 I was pulling out from a side road onto a main highway when all of a sudden the car completely lost power and all the lights were flashing, then the engine just stopped. The brakes even went to the floor. Thankfully there were no cars coming down the main highway and I was able to get the car to the side of the road. Called a tow truck and had it towed to the Hyundai dealer in chattanooga, TN. The service guy named andy tried to convince me that my oil was low causing the engine to lock up, stating the oil looked like sludge! we were unable to present every single piece of maintenance record, so we were told our warranty was void. The oil had just been changed in April and there was absolutely no reason for the engine to lock up or "look like sludge"!. The dealership wanted almost $6000. 00 to replace the motor (we don't have that kind of money accessible). When we argued about the warranty, the service department asked us to pay $675. 00 to tear the engine down. "if" they found a defect in the motor, it still might not be covered!! needless to say, the car was towed to my brothers home and still sets there today all the while we are still making the monthly payment and full coverage insurance on a 2-year old car that we can't drive!!.

I was driving home and slowed to let someone in front of me turn left into a grocery parking lot. The car suddenly started surging mad I could not stop it with the brake pedal all the way to floor. However, I did hit the car in font of me, with no damage to her car. I had popped the front right side of the bumper on my car. So we went on with our business when she found no damage to her vehicle. I had to turn the car off to stop the car from moving. I called the dealer glenn Hyundai and told them of the incident, they in turn told me this would be nearly impossible for this to happen! it did happen!! they called me after receiving the vehicle via tow truck and told me the throttle was dirty and needed to be cleaned. So I told them go ahead and then about half hour later they called and said the car needed a throttle position assembly replaced. They had already charged me for the cleaning of the throttle, and then charged me to replace it also. Doesn't cleaning come with replacing the throttle assembly? I think this should be investigated and to see how many other Hyundai's have had this problem. They supposedly contacted Hyundai corporate USA, however, I have yet to hear anything from Hyundai. I really hope all is safe now????.

My car revved to between 4 and 6 thousand rpms when I was parking in my work parking garage. In the process I ended up hitting two suvs and did over $5,500 in damage to my car. I took my car to our Hyundai service to have the engine looked at and they couldn't find anything wrong with it. On Friday, may 15 as I was driving home from work on rt 70 at the top of braddock mountain my car revved again for no reason. Luckily I wasn't in traffic when the rev happened. This rev has also happened when my husband was driving the car.

I have a 2011 Hyundai Sonata,my first car I purchase it almost 4 months ago I'll had 2 oil changes including the one the dealer did before I bought it. I was simply driving home & heard a weird nosie so I pulled over my battery died and car engine started to smoke I was giving no warning sign or indicator to check my oil or anything. I had my car towed to suntrup Hyundai were I was told my engine was seized and would cost me from 5,000-9,000 for a new or used. How does a well-maintained car go from normal to a total lost? I'll done my research so my question for you is when will you recall this entire car? will indeed be joining the class action lawsuit against Hyundai. I have no warranty & don't even want the car with a new engine. I just want Hyundai to buy the car back it's a serious safety risk I'll stick with american made vehicles.
