While I was driving my car on a two-way street, all of the sensor lights on my vehicle came on. I pulled the car over and now it won't crank. The radio is working, but the car is not cranking. Also, whenever I place my car into park, I would have to turn the car off and start it back in order to shift my gear into drive or reverse.
My radio display and all speakers completely quick working I searched for months here and there when I had time I even upgraded my radio to the factory touch screen radio and the display came on but no sound and finally I took the factory amp apart and it had water damage I was not in a wreck or anything only thing I could think of how it got wet is terrible placement of factory amp on the outside of the frame in the trunk so now I have to ride in silence or with a bluetooth speaker because Hyundai wanted to put and electronic in the worst place possible where it is completely exposed to road degree and in my case rain.
Takata loud rpm when starting then loud clicking in steering wheel coupler bad now brakes having issues and axles clicking radio goes on and off. Lights keep burning out.
Sometimes while driving the radio will cut off and all of the presetting get erased. When the heater is on there is a burning smell. The horn is very weak. Front end has a loud rattling noise. The seatbelts seem loose.
We took delivery of our 2011 Hyundai Sonata on 4/29/2010. As we were driving home a car on the lane next to us on my right hand side started shifting onto my lane. I blew the horn but he still cut me off. At the light I asked the person who cut me off if he didn't hear me blowing my horn at him and he said no I am really sorry but I didn't see you and I didn't hear your horn either. When I got home I got into my other car and started it with the ac on and no radio I asked my wife to press the horn on the Sonata and I can barely hear it and we were just sitting in our driveway with no road noise and my radio off. I looked into this issue online and others have the same issue with the horns on their Sonata. Hyundai also admitted that the horn was weak but I still see no change or recall. Please look into this matter before it cost someone their life or a real bad accident.
