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.

In 2019 I had my computer replaced with less than 60K miles! I had every light come up on the dash board. I've been complaining to the dealer ship about my car running out of oil, the engine makes weird noises as it currently has less than 80K miles on it. I had my oil changed on April 15th. 2020 6 days later my cars engine was making noises checked my oil and I was down almost 2 quarts in less than a week. I bought this car brand new and have had nothing but issues with it.

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.

All dashboard lights are turning on. The car loses power steering. The car will at times not turn on. This happened a few months after I purchased the car. Hyundai can't seem to find the problem. The problem eventually goes away by itself for a few months and reappears again. We had the fuel sensor and battery replaced. They said my alternator and starter is still good. The car never stalled during driving only looses power steering which can be dangerous while driving. We noticed when we adjust the steering wheel up and down, it cleared the issue for a few months as well. I believe 2015 Hyundai Sonatas are experiencing electrical issues. I read online other owners having the same issue.

The ventilated seats does not blow cool air even with air conditioning on max. However, my other Sonata (same year and model) does not have this issue. Does it mean 50% of Hyundai's ventilated seats fail?

I must start by saying that english is not my first language, Korean is and I would like a translator when I am called for reference. On 07/16/2019 I purchased a 2015 Hyundai Sonata from carvana and have run into the following problems: The battery was not the correct size for that model car, the engine air intake was completely missing, and the supercharger blew up 4 days after I bought the car. I have sent an email to carvana but never received a response. I have more documents pertaining to this matter that are too large to attached and will be able to send them via email.

The contact owns a 2015 Hyundai Sonata. While driving various speeds, the 'check charging system", "safely stop", and "do not drive' indicators illuminated. The vehicle was coasted to the side of the road and towed to all star Hyundai of baton rouge (225-274-0071, located at 10313 airline highway, baton rouge, la 70816) to be diagnosed, but the technician was unable to determine the cause of the failure. The failure recurred several times and the vehicle was taken to eddie tourelle's northpark Hyundai (985-801-7000, located at 953 highway 190 North, covington, la 70433) where another diagnostic test was performed; however, the cause of the failure could not be determined. The failure recurred. The manufacturer was made aware of the failure and stated that based on the diagnostic tests by the two dealers, which yielded nothing, they could be assist. The vehicle was not repaired. The failure mileage was 20,917.

I believe my vehicle may have a faulty headlight/signaling switch. Whenever I am driving it will randomly switch between the modes of drl, headlights or just off completely. Another issue I have more often then not is when I am trying to signal the blinkers will not turn on at all, and when they do its about 30sec to a minute after I initially moved the switch myself. All this happens while the car is in motion, lastly their have been three occasions where I have turned my car off completely and then came back hours later to find that the drl lights had turned on on their own, 1 out of the 3 times so far this issue has drained my battery. I feel like this might be a issue with the wiring inside the switch.
