My 19 year old daughter was driving home from the store and the car shut down in the middle of driving all power went out steering became hard and brakes became hard. And something smelled as if it was burning. We are the second owners of the car and barely drive it. It was purchased 2 years ago and regular maintenance is kept on the car. Unfortunately we don't have a warranty on the car any longer and still making payments. This is very dangerous and could have caused a major accident and as well as cost my daughter her life if she didn't know how to control the car when everything shut down in traffic.

Engine oil consumption: More than 1 quarter every 1,000 miles but the mechanic did not find any leaking. The vehicle has total 55,000 miles and I drive about 1000 miles/month on freeway and local streets. I also found many reports on the websites and many Hyundai dealers had tested the oil consumption and waiting to the response from Hyundai headquarters.

The week of 2/3/20 I reported my vehicle's lose of power at interstate speeds and the illumination & chiming of the check engine light. I took the car to the dealer where they ran engine diagnostics and began an oil consumption test. On 3/2/20 the vehicle again lost power on the interstate. Again I took it to the dealer where they did the T3G campaign. Yesterday 3/17/20 the engine light came on and remained on for 5 starts of the engine. The dealer could not replicate the symptom on 3/18/20. The vehicle failed the oil consumption test by 363 miles and the dealer is submitting a claim for a new engine. This model year car has serious defects and may not be safe to drive.

2015 Hyundai Sonata SE caught on fire after being parked in apartment building parking lot on 1/12/20. Car was serviced at certified Hyundai dealership repair shop on 1/10/20 for recall work and to investigate oil pressure light that would come on and off intermittently. Repair shop claimed there was an oil leak and recommended an oil change/valve cover gasket replacement (last oil change just under 5000 miles prior). Car began smelling as if something was burning later after leaving repair shop, as well as the next day, so shop was called back on 1/11/20 and message was left that it needed to be brought back in on Monday morning (1/13/20). Oil pressure light did not come back on, however, nor did any other warning lights. Car was driven sparingly in the neighborhood primarily for work purposes over the weekend and parked after approx. 12 minute commute home from work on Sunday evening (1/12/20). I returned a little over an hour later to discover the situation and learned that the fire dept. Had already come and gone. Immediately called police/fire dept. To find out what had happened and was informed that neighbors had called the police due to seeing it on fire about 10-15 minutes after I had parked the car. I am unclear of the exact nature of the problem, though oil appears to have been leaking (and burning - some light smoke was visible under hood on 1/11 & 1/12) after repairs, and fire is said to have started in the engine compartment. Insurance company was immediately notified as well and deemed the vehicle a total loss and towed it away for further investigation as to cause of fire on 1/14/20. Dealership where car was serviced 2 days prior is of concern since car appeared in worse condition after repairs than before, but I am uncertain of their liability in this case.

The car suddenly loses the ability to accelerate making it very stressful to drive as you are not certain when this will happen. At first it is intermittent but eventually it simply stays that way once the issue begins while you are driving, hence the car will have an almost impossible time retaining speed on the highway or accelerating at a light or as you merge onto highways. Changing the driver mode to sport appears to have a positive effect as it causes much more aggressive gear shifting but it then stays in the same gear for too long reaching rps that feel unsafe for the engine itself. This is now the third tie this happens and it is also the more severe manifestation of the problem, . the first time the dealer asserted they were not able to diagnose it but returned the car without the problem. The second time it happened they apologized and said that it was an issue with the engines computer algorithm, that apparently the computer learns from the way in which one drives and so is adaptive but that sometimes it can become corrupted. This third time the dealer told me it would take only a couple of hours to fix but now it has been three days and they have not called me back. They did leave a message that apparently they are ordering parts and will be fixing it. My issue now is that its a third time and it is clear that something in the car is defective and now we are going to be almost completely paranoid of it happening again at a critically dangerous intersection or merge area. We have been lucky so far but it is a family car and I do not feel safe in the car anymore given the repeating nature of this problem and the lack of information out there form the manufacturer as to what exactly is going on.

8-10 times in the past year while driving car in freeway hybrid system warning comes up prompting to safely pull over and turn off car. Car then starts slowing down. Have taken the vehicle to Hyundai service 4-5 times and they keep finding broken parts that dont fix the problem.

I immediately pulled to the side of the road to investigate and the noise sounded like rocks grinding. I checked oil and it was full. When car was restarted the noise resumed. I turned off the car and it didn't start again. Towed to a garage and they said there were metal shavings in the oil and motor was locked up. 125K miles and regularly maintained. Engine was replaced at a cost of $4000.
