Steering Wheel Control Buttons not working

Question by posted 10 months ago in Elantra

the radio control buttons located in the steering wheel start not working correctly. when I press the + sound the radio volume goes down and when I press - sound the sound goes up. Also, the cruise control buttons need double-click on it to activate. then after a few months, the Airbag light got On and the radio buttons become completely not working and cruise-control not working as well. but the horn still works well in all positions.
