The steering wheel began clunking when it was turned even slightly. When I took it to get repaired, they could not tell me if it was the steering shaft or the rack and pinion. Also, shortly after we got the car, the engine went out in it (before the engine recall was issued). The dealership put in a junkyard engine and now I am having the same issue with it knocking. The left front axle boot is torn as well, and there is no indication how this occurred. The rear brake and tail lights are impossible to keep working. We change one and another goes out. We went as far as to change all of the brake and tail lights at the same time and less than a week later one was out again. The cruise control will come on but is unable to be set to control the speed of the car.

Airbag indicator light came on (and stayed on) when I started the vehicle in a parking lot on 12/13/2017. I immediately brought the vehicle to the dealership and the dealership said it was related to the passenger side and that the passenger side airbag would not deploy until the problem was found and necessary repairs completed. Research shows that this is a pervasive issue in Hyundai Sonatas for all model years to date. Several forums discuss this same issue and I see that several complaints have been submitted through the NHTSA as well. This issue involves both the airbags and the electrical system (sensors; passenger seat track) and poses a major safety risk. I was allowed to bring the car home, in order to weigh my options. I have driven the car once, and cycled the car on and off in my driveway. The airbag dash indicator remains illuminated. The cost to repair this issue feels exorbitant, especially since it appears to be more related to manufacturer defect that normal wear and tear. I am now stuck paying $1500 or feeling completely unsafe having a passenger ride in my front seat.

The controls on my steering wheel will randomly quit working. The cruise control will work fine one time and then the next I can't hit set or the cancel button will be the cruise or it will flip through the other options (trip button). If I hit the steering wheel in this vicinity it will work correctly sometimes. The volume button will either mute, or the + will actual decrease the volume. The button to change the station (presets) will change the mode (am, cd, sirius...) sometimes one direction (up) works and the other does something else random. All of the steering wheel controls seem to have a mind of their own and do not work correctly most days vs some days the buttons work fine. I took it to the dealership prior to the warranty expiring and it worked fine. Next day, issues again. I saw other complaints about this but can't seem to make it happen when I need it to. Frustrating since it is safer to use these controls that the buttons on the dash.

2011 Hyundai Sonata limited 2.4L. Left brake light out for the forth time.. but, this time the new bulb replacement wouldn't fix the problem. I had to have all the recalls fixed, so I made an appointment with the closest dealership an hour away in terre haute, in. The very next day. After they fixed one of the recalls they had to reschedule me for the following day to do all the rest, as they stated it would take most of the day to do. So, the next day my partner following behind me noticed that now both my brake lights were completely out! we again reported the brake light situation to the dealership upon arriving at 8am and dropped off the car. At 5pm that day we called to check on their progress and they stated that they were finishing up on the recalls but that the wiring harness on the brake lights had all melted together on both sides! and, they were unable to fix it until the next day. Ugh.. then, quoted me $523.23 to fix it! I've read countless people complaining of this same issue and wonder how many accidents this has caused. Dangerous and absolutely ridiculous! this should be covered in a recall.

I've had my car since August 17th 2016, ever since then I have replaced my front and back lights over 40 times. Now this happens with me turning my automatic lights off ( if I'm saying that right) or even with leaving them on. It's seriously the most annoying thing ever. And yes I'm putting the lights in correctly even getting mechanics to put them in as well just to make sure!!!!!!

Brake issue, - when I press on brake pad the rear light seems to either get stuck making cars behind me think I am in the stop mode or will be stopping soon, it comes on and off time to time or either stays illuminated. I did youtube something about inserting a penny on the spot under break pedel. Electrical issue - me key gets stuck in the ignition when the car is in park postion, however the only way to dislodge the key is disconnecting my battery to shut down the car then I can turn the key to remove it from ignition, could it be my anti-theft system malfunctioning? steering wheel issue - hear a click in the steering column as if something had loose inside. Door handle/ panel issue- on handle and steering wheel is chipping off

My airbag light came on with no reason. I did not hit my car, nor got into any accident at all. I took to dealership who charged me $165 for diagnostics and advised that my front passenger seat airbag module / sensor is bad and will cost $980 if I wanted to get it fixed. I have received recall notice from tk holding that states my car is part of the airbag fix / recall but dealer refuses to fix without almost thousand dollar.

While driving the car, it stalled and I struggled to turn into a parking space. I had a difficult time turning the steering wheel, then immediately on my dashboard, the eps light appeared. The car wont start immediately, it does not lock w/ the key, I have to manually lock it- when done manually the car does not start. However, when the key works the car starts. The entire dashboard has to be reprogrammed bc of the eps issue. I researched the eps issue and found the recall on Hyundai for this issue. When in a stationary position, when the car does not start, I wait a moment and try several times and then it starts. My business involves traveling and this is very concerning as many times I am traveling alone.
