Failure Date: 08/13/2015

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.

Failure Date: 08/08/2015

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.

Failure Date: 08/04/2015

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.

Failure Date: 07/03/2015

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.

Failure Date: 05/21/2015

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.

Was driving the car when I noticed some "clicking" noises coming from the engine. I immediately began experiencing severe engine power loss and, as I was on my way home from work and a local Hyundai dealer was nearby, I went there. Upon arrival, I advised the service person of the symptoms I'd experienced. After a call from the dealer the next day, I was advised that Hyundai wanted them (the dealer) to completely tear the engine down to take pictures of the internals to assess the damage. The representative also told me that the oil was extremely low on the dipstick, so low that it didn't even register. Note: the car was next scheduled to receive an oil change at 57,600 miles, and this occurred at 56,000. A few days later, I hear back that "Hyundai" had declined the warranty coverage, so I contacted Hyundai and they stated that the dealership is the one who had in fact denied the warranty coverage, and would be contacting them to understand the reason(s) for the denial. After researching the issues, I've found a lawyer opening a class action lawsuit, as others have reported this same issue. . Read more...

When attempting to accelerate the vehicle to get onto the freeway the engine lost all power. This incident has happened multiple times on multiple occasions, each time Hyundai and the dealership have failed to identify and fix the problem. Each power failure event has been a near accident. I am concerned for the my passengers and my own safety. The vehicle has received all regular maintenance, oil changes and recalls. A case has been opened with Hyundai customer support.

During routine oil change, was told that I needed a new engine block and it was not covered under warranty. Was told this was due to low oil in the car. After arguing for 2 weeks with dealer that I purchased the vehicle from (I am the original owner) and the only dealer that has ever serviced the vehicle, they replaced the small engine block, under warranty. Took 1 month.

Failure Date: 02/25/2015

At 1540 miles 2015 Hyundai Sonata limited engine cam advance sensor failed. This caused engine running rough and limited power with inability to climb hills without constantly downshifting. Highway driving is dangerous due to inability to accelerate and merge and loss of power on hills. Other owners are unable to start their cars altogether. Engine monitor warned of problem and recommended full systems diagnostic which pointed to cam sensor issue. Supply of sensors was backlogged due to multiple failures nationally. This is also evidenced by the number of online owner complaints for the same issue many stating long delays in obtaining the part and multiple part failures. In my case, after 200 miles with the new sensor if failed a second time and I am again waiting for parts. The vehicle now has 1700 miles on it since new. For a new vehicle this is a totally unacceptable level of quality. While I was told the o-ring seal fails causing oil to saturate the sensor I personally believe they do not know the full reason for the failures, I. E. Poor sensor manufacturing, materials issue, o-ring issue etc. In speaking with Hyundai corporate personnel it became obvious to me that they are trying to avoid a national recall by understating the scope of this problem nationally and trying to minimalize the extent of the problem in our conversations. I suggest an investigation to determine the extent of the issue and see if it warrants a recall. For other owners or potential buyers, while this failure has been my primary complaint I have noted other issues with the electronic warning sensor inconsistency and cabin electronics systems which have not been resolved. This my first experience with owning a Hyundai and I am terribly disappointed. Next step is lemon law filing.

Failure Date: 02/14/2015

I was driving on the interstate 2/14/15 and started to slow down due to traffic. As I slowed to approximately 25 mph, my car died. I had enough momentum to make it over to the right shoulder. I had my vehicle towed to the local dealership who stated that my starter had gone bad on 2/14/15. I waited to hear back on Monday, 2/16/15 that they had fixed the starter, but instead they called and stated that my engine had seized up and I would need to purchase a new engine for $5600 (including labor). I made regular oil changes (I was not exactly 8,000 miles for every oil change though), I completed all recall requirements, I had my oil pan replaced Dec 2013, I had the car looked over 100% Dec 2013 and it was found to be in great working condition, & my engine actually turned over when it died on 2/14/15, so the starter made sense. I did some research, and it appears there is a class action lawsuit for ~ 30 incidents where the Hyundai engine seized on this year, make, & model. I am very frustrated that I have to pay for an engine that is pretty much what the car is worth now, when an engine should not seize up after only 120,000 miles when taken care of properly. The fact that it stopped while I was still driving is extremely unsafe and could have easily resulted in a wreck. I believe that the engines on this year, make and model should be investigated and should be recalled due to safety reasons.

I purchased the car on 10/22/13 and I have kept the maintenance up on the car. Then on 2/13/15 (not to mention that it was my birthday) as I was driving home from work the car cut off on me. I had the car towed to the dealership where I purchased the car from and was told that the motor was blown up. Now here I was thinking that I kept very good care of my car and that a car with only 63k miles should not have had any engine problems! now here it is almost 3 months later I still have to make car payments on a car that I can not drive.

Earlier that day the wrench was lit up on the dashboard, but it disappeared. I was driving out of my neighborhood at about 15-20 mph and the screen read "warning! do not drive! irreparable damage to ? I can't remember" it started to freeze the driving. Then I parked it and it would not start back up. It was towed to the dealer and they replaced the battery and hpcu. It scares me to think what would have happened if I was on the freeway. I bought this car April 20, 2014 and now can just get 2/3's what I paid for it. Sad, but true. When I get some money I will be trading this in as I am nervous driving this car now.

Was taking left hand turn on major road, and all of the lights lit up inside the vehicle and the engine just died. I pulled over to the side of the road and had all electrical systems but the engine would not turn over. I popped the hood and saw smoke from the engine, so checked the oil and there wasn't any on the dipstick. Had to call a tow truck to have vehicle taken back to the last place I had the oil changed. They determined that the engine had seized up and that I needed to replace it for $7000. No check oil engine light came on and always had oil changed on regular basis, because I do a lot of highway driving for work.
