The car has failed to start on multiple occasions. I enter the car, press the break and the push to start button, and the car fails to ignite. It happens normally when it is colder, but will still do it when it is warmer out.

The contact owns a 2015 Hyundai Sonata. The contact stated that the vehicle misfired and took a while to start. The service engine warning light was illuminated. The vehicle was taken to an independent mechanic who found an unknown code, and performed a hard reset. The failure recurred. The vehicle was taken to the crenshaw Hyundai dealer located at 330 huffman mill rd, burlington, nc 27215, where it was diagnosed that the cvt sensor may need to be cleaned. The technician looked at the sensor and informed the contact the sensor needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was not repaired.

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.

When I have the "lane departure" running it cancels out the "blind spot detection". the dealer has recalibrated the sensors twice an finally told me I couldn't operate both of those two items and the same time. This occurred going down the road, city or highway or city streets.

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.

Navigation system replaced twice. Defective gps, bluetooth and speaker. Now in dealership for the 3rd time for 5 weeks and still can't find the problem.

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?

- Alhambra, CA, USA

At 45,800 miles my Sonata could not reach 60 mph and the RPM could not reach 2000. I also noticed the gas mileage drops the Sonata had 35,000 miles on it. I took the car to the dealer and was told it needs new engine.
