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.

Bsd issue light is on, traction control light, ABS light. Dealer said right rear hub sensor was faulty. Had this replaced and didn't fix problem. Was charged $136 just to diagnose issue but changing the righty rear sensor hub didn't fix anything. Dealer says next repairs will be almost $500. Issues with warning lights happened during normal weather and driving conditions.

While driving down the highway the warning light for the bsd sysiem started blinking on and off. The next morning it stayed on. I took it to the dealer and after two hours the service man came in and told me they couldn't find the problem but they thought it would be behind the rear bumper. They wanted me to pay $150 to remove the rear bumper to check it. He said if it was a problem there I would most likely have to pay for the repair as it was likely my fault. I refused to do so as I felt it should be covered by the waranty. I no longer have a functional blind side detecter. To detect traffic in my driver side blind spot.

To note vehicle had a complete evaluation 1 week prior with no current or upcoming issues. Upon starting car "ABS light, traction light, bsd (blind side detection) light" came on. Upon driving, my bsd sensors did not operate, and engine made whistling sound upon acceleration and would not go over 40mph without the power being pulled from the engine. Also to note my car was apparently trying to be in a higher gear at 30mph (5th gear). All of this is very suspicious as the car has only been serviced at dealerships with most recent being 1 week prior. Service department seemed very poor at explaining the cause for the simultaneous malfunctions of all these systems. I do not currently feel as safe with this vehicle as I have before.

Bsd system dose not work as it should be, I took it to the dealer and they clear the code and preform calibration now there is not error code but dose not preform as it should be, dose not detect any car in blind spot, it is to risky to say I do relay on this system but dosenot detect the cars

I was driving at 6:20 am on the New Jersey turnpike. I was in the left lane and going approximately 70 mph using the scc (smart cruise control). All of the sudden, the lights start flashing and the car completely turns off. Since it was before sunrise, everything was black and I couldn't even see where I was driving, not to mention that the steering wheel became locked. 10 seconds later, the care came back to "life". it did that same intro with the "system check" thing as it does when the car is started from a park position- only I was on the highway going 70 mph. I have never heard of something so absurd, but I guarantee that if this was during rush hour or a busier time during the day- there would have been a major accident!

In the snow, my Hyundai Sonata will drive fine until turning. During turning, even with minimal snow, my brakes lock up and my car slides slowly but at that point I am unable to do anything, usually making me hit a curb. This has happened twice in the last two weeks costing me $2200. I have had two cars before my Hyundai Sonata and haven't had issues with such a problem. The mechanic scratches his head in confusion as to how almost the exact same thing happen in such a small time frame. It is a major safety issue, I believe something with traction control or braking is wrong. Had I been a worse driver the damages could be worse.
