Selected complaints filed with NHTSA by 2015 Hyundai Sonata owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2015 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the sunroof wind deflector detached from the vehicle and flew off. The local dealer where the vehicle was serviced under an unknown recall related to the failure was contacted; however, the contact was informed that the recall repair was completed in 2017 as a one-time free repair. The manufacturer was contacted and confirmed that the recall was a one-time repair. The vehicle was not repaired. The failure mileage was approximately 150,000.
I was driving my 2015 Hyundai Sonata approximately 35 mph after leaving the Hyundai dealership following an engine replacement when the hood unexpectedly flew completely open without warning. The hood struck the windshield, completely obstructing my forward visibility and creating an extremely dangerous situation. I was able to safely pull over without causing a collision, but the vehicle sustained extensive damage and was declared a total loss by my insurance company. During the same service visit in which the engine was replaced, the dealership recommended replacing the hood latches, but I declined that repair. Hyundai later informed me that the hood latching system was functioning properly after the engine replacement and that the vehicle passed its post-repair inspection and road test. …
The bug guard/wind deflector has become detached (AGAIN) on my panoramic sunroof while driving on the freeway. It puts myself & passengers as well as other people driving on the freeway in danger as there is a known issue that the detached bug guard/wind deflector is what causes detaching window panels or shattered sunroof panels. I took my vehicle to the Dealership in Salt Lake City, UT for a repair on the bug guard and was told since it had been repaired before through the original recall, they would not repair it again. (the fix is loctite super glue). I asked about my warranty on the panoramic sunroof and they told me that it only covers the glass and I would need to pay $160.00 for the diagnosis of the detached bug guard. - which can be seen by opening the sunroof. …
When auto lights are engaged and the blinkers are engaged, the light will turn off and it will blink in the wrong direction for a few times and then blink the correct direction. While in auto lights and you turn a curve they will sometimes go off. Now I have an issue with my AC - it goes on and off randomly. Had it looked at and they cannot find an issue with the components but said it could be an electrical issue. BYW, Hyundai replaced the motor in this car as well because it had so many issues. I was told the issues now could be caused from them replacing the motor and causing an electrical issue. The paint is also peeling and they had a recall on the paint, but the paint on my car didn't start peeling until after their warranty had expired. This is a known issue with 2015 models - they know the paint is bad but won't fix it. …
We have a 2015 hyundai sonata with a panoramic sunroof. About 2 weeks ago we opened the sunroof and noticed the wind deflector popped up higher than normal. When we tried to close the sunroof it would not close. The deflector was sticking up and we had to push it down quickly to avoid punching our hands in the sunroof. It still did not want to close after we tried, but the sunroof was down almost all the way. We called hyundai the same day to get it looked at. We thought maybe it broke something in the process of closing because it didn't look closed 100%. They could not get us in until mid August. We were not too concerned because the sunroof was mostly closed down so rain could not get in. Today driving about 50 mph the sunroof just FLEW off the car and shattered into a million pieces in full traffic. Someone could have been seriously injured!! …
On Friday, April 18, I opened my panoramic sunroof on my car. When I did, the wind deflector became detached from the sunroof mechanism. So I attempted to close the sunroof and when I did, the would not close all the way and the sunroof appeared to become off track. No the roof will not close all the way leaving it popped open about an inch. I called a couple of Hyundai dealers and they both said that there was an extended warranty provided by Hyundai. Based on my car's original purchase date, I am out of warranty by 6 weeks on time but under the mileage of 120,000 mileage limit. . I have read that this has caused the glass portion of the sunroof to blow out of the car because it won't close all the way. I believe that this poses a threat not only to me and my passengers as well as possibly someone riding behind me me getting hit because the sunroof came loose and hitting them as well.
The panoramic sunroof wind deflector is off I seen online there was a recall about that. I call hyundai customer service about it they said it's been fix already in 2016. I'm a new owner and not sure where the work was done before I got it, but it came unglued again. I purchased the car from John amato hyundai dealership and get the services done there because I'm under a forever warranty and can't going anywhere eles because of the warranty. Which nothing is done free on it and all the work I've had done from them I believe they don't do everything because it still rides and sounds the same and there #1 excuse is that's how hyundai cars sounds. So with that being said if John amato fixed it, I see why it failed again. Can check my car to see if recalls were really preformed and done correctly and what's needed now to be like new again.
In Nov 2021, the door handle on the rear driver side door came off. Today, the front driver door handle broke. This is a huge safety matter because I cannot get into my car without opening the front passenger door and crawling into the driver seat. In the case of an emergency, this could be detrimental. There are also other reports of door handles falling off on the Internet (https://www.abcactionnews.com/money/consumer/taking-action-for-you/door-handle-defect-forces-woman-to-crawl-through-the-back-of-her-car-to-get-to-the-drivers-seat?_amp=true). I have called Hyundai and they refuse to do anything about this issue and it costs 300+ per handle to replace. There is no reason door handles should be falling off...especially ones that you don't use as often, such as the one for my rear driver side door.
The biggest problem is that the oil is going into the spark plugs this started happening approx 1 year ago and I have been complaining about this to Hyundai to the B.B.B. and the Attny Generals office I am told to take it too hyundai dealership whenI mentioned they will charge me to tell me what I have already been told I was told by Hyundai they can not control there own dealership??? Keep in mind I still owe on this vehicle and have not owned it for even 5 years...The paint is coming off all over the vehicle and the seat belts do not retract as they are suppose too! This is not the first Hyundai Sonata I have owned but it still has existing problems and family and friends have the same problems,Please help to get this fixed!!Thank you Vehicle was purchased in Danvers, MA
While driving on the highway Emmy pearl white paint began chipping on my car flying up into my field of vision which not only was distracting while driving but appeared as if it came from another vehicle even though it as from my vehicle. Prior to pulling over to see what happened, I ended up trying to avoid this thing that flew into my field of vision out of no where when I realized it was my chipping paint. I have contacted Hyundai who states they aren't liable for the damage as it is out of their paint warranty. If this issue doesn't get resolved and these car companies aren't held liable for their known mistake, then more accidents will occur in the future.
