As the owner of a 2015 Hyundai Sonata, You may be experiencing an issue with the information display screen going black on Your stereo system. There are typically two things that result in the display not functioning. The first potential cause of the problem is bad wiring, or wiring that has a loose connection. This can sometimes occur in the event of hitting large bumps, or accidents. Check the wiring and reconnect any loose wires, and replace any that show signs of wear. This can cost You between $22 and $50 in parts alone. The other potential problem is a faulty ECU. If this is the case, it will cost You around $120 to $248 to replace it.
