The radio stopped working completely, which seems like a common problem. But in addition the lights were malfunctioning from that point on. 12 different error warnings appeared on the readout about different lights not working. I checked the fuses and all of them were ok, not burned. Several years ago I had one of the headlights intermittently not work. At that point I checked the fuses and there was one fuse that had a deformed plastic cap, but the metal part was still in one piece. Part of the fuse box it was inserted in was melted. This all happened when I first started the car. Obviously I could not operate the car since the brake lights, turn signals, and headlights were all affected. The diagnostic display in the car also showed to check the airbags and stability control.
The lights are all crossed. The left turn signal is weaker on the driver mirror. The overhead lights seemed to be crossed. You turn one off and the passenger lights in back come on. The bluetooth stopped working. It is like it has a shirt in it. This is while driving as well as stationary in car port.
