Hyundai Sonata owners have reported 107 problems related to engine and engine cooling (under the engine and engine cooling category).
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.

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.

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.
I was driving on the highway when my car threw a crank rod. In doing some research I see that this has happened on numerous vehicles having faulty bolts on the crank rod cap. There has been no recall but is an ongoing issue with many owners.

In the span 2 months, there were 2 occasions where my car would not start. I thought it was the battery and had someone jump me and it still wouldn't start. However, after trying several times, car would finally start. One other time I pulled into a store and when I came out, my car wouldn't start. After several attempts, it finally started. Then on November 28th, 2014, my boyfriend was driving my car and it just stopped running. I had it towed to an independent mechanic and they stated that the engine had seized. I did not have any warning or indication that anything was wrong. Today I have to have it towed to the Hyundai dealership and they will let me know the exact problem and if it is covered under the warranty.
As I began driving my 2011 Hyundai Sonata that morning I heard a rattle whenever my rpm would reach between 2-3k. I contacted my local Hyundai dealership and made an appointment. Today 11/20/14i was told that my engine needed to be replaced. My car was previously in the dealership late September 2014for an oil change and also due to a small knock/bang as I accelerated. The technician found the knock to be a support hitting against the firewall. Upon tightening said support the problem went away. The car was reportidly teat driven by the technician numerous times to conclude that the problem was fixed. Oil change was done as usual and my car was given a clean bill of health (only a recommendation of brakes getting low).
At approximately 5pm on October 10th 2014 I pulled out of a parking lot in harrisburg, nc. When the car reached 15 mph it did not shift (the car is equipped with automatic transmission with shiftronic manual controls) and I had to shift the car manually into second gear and each successive gear. After doing so I noticed the car had turned off while driving. I was able to pull off the road with no incident and restart the car. The following day, I noticed clicking under the hood and took it into the dealer. After their examination they determined the engine had a defect. They are replacing the engine.

While at a red light on highway 45 in whistler alabama car just cut off and would not crank back up, police had to come and stop traffic and push car out of the highway so it wouldn't be an accident because it was near the interstate exits to highway 45.
I was driving down a 4 laneroadway when the engine stopped. I was able to coast into a gas station and noticed a small amount of smoke coming from the engine. Had it towed to a dealership and 2 days later they told me it was a seized engine and that it was only 1/2 quaret low. I filed a claim with my extended warranty service. They sent an inspector out and his finding were it was 2-3 quarts low and cited owner negect. Warranty service denied the claim. I use royal purple synthetic oil and have used this same oil for the past 15 years in all my vehicles. I had my oil changed in July. . Approxiamtely 3 months prior.
While driving uphill at roughly 50 mph the rod bearing in my 2. 4 liter Hyundai Sonata failed. The engine was running approximately 5000 rpms at the time of failure. The motors was ruined. The vehicle has been maintained according to the normal use maintenance schedule, having oil changes every 5,000 miles.
An engine rod blew a hole in the engine block. This was done at a speed of around 48 mph. This is based on the dealership technician¿¿ inspection. Luckily I was not next to another car when this occurred or it very likely would have caused an accident.
My 2011 Sonata just stopped one day, with no warning. No lights came on, I call roadside assistance, key hyandai in milford, CT took 3 days to get back to me, and told me that my engine seized due to lack of oil. I had oil in my car, they said that sludge is in the engine because I did not keep my regular schedule oil change with them. I check my oil! but why didn't the car alert me? why didn't the oil light come one and tell me something was wrong? factory warranty will not cover the car even though I shown proof of doing oil change else where. I bought this car with 5 miles, how can a new car engine just seize!.

While driving on the freeway the car started accelerating on its own. Tried pumping the gas pedal to release it, car still accelerated. Brakes did little good. Was able to down shift into first gear, then into neutral and utilizing the emergency brake was able to get the car slowed down enough to cut the engine. Some problem happened immediately when I turned the car back on trying to get it off the freeway off ramp. Was able to stop safely in a parking lot without hitting anything. Had the car towed to the dealership, where they said it was a problem with the throttle.

I was turning on to smith switch road in ashburn virginia from waxpool road. I reached to turn on the emergency flashers due to bicyclist on the roadway and I bumped the starter switch for the car and it shut the car off while it was still in motion. This caused the steering to be heavy and brakes very hard to use. Luckily I was able to coast off the road without an accident. I had to stop the vehicle totally and put back into park before it would start again and it would not start again while it was coasting. I tried and it didn't work.
The contact owns a 2012 Hyundai Sonata. The contact stated that after parking and turning off the vehicle in her residential garage, the vehicle started rolling backwards. In an attempt to stop the vehicle the contact fell which caused her to scrape her chin needing 10 stitches. The contact was taken to the emergency room. The failure mileage was 39,000. The consumer stated she and the police attempted to piece together the scenario, that the vehicle was not in park, when she turned it off. The consumer stated the vehicle could be put into any gear, and it could roll, whether it was on a flat of hilly surface. Updated 08/20/14 updated 8/27/cn.
In may 2014, while driving at about 40 mph, maybe 1200 rpm, my engine suddenly accelerated to 4500-5000 rpm, without a simultaneous rise in speed. A week or two later, the car did the same, under about the same conditions. The dealer could find no faults or codes, and could not duplicate the occurrence; not surprising since it was sporadic. The problem continued, with considerably more frequency; almost daily. Again I took it to the dealer in late July (mccafferty Hyundai, langhorne, PA), and while a technician was driving with me, the engine raced again. They told me that there was a tech bulletin on this problem, and they would repair the car. The problem was in a module and needed recoding. At least that's what I thought they said. That repair seemed to cure the problem, until September, when a single occurrence happened. I though this was maybe a fluke, but the problem happened several more times in the following weeks. Today, 11/4/14, after several days in the dealer's shop, an insurance service tech said he could find no problem. I am now afraid to drive this car. While the car does not accelerate, maybe it's just a matter of time when the racing engine will cause severe acceleration and a subsequent accident.
