The standard headlamps inconsistently and often shut off. The bright lamps remain working, thank goodness. This happens usually when in motion, or right when the ignition is turned on. Weather does not seem to be a factor.

I noticed a electrical burning smell while driving on a side street. The engine made an unusual noise so I pulled over, turned the car off and put on the hazard lights. While waiting for the tow truck, the car started with no key in the ignition. The car ran for a short time then stopped and attempted to restart itself about 5 times. Our mechanic took a look at it and said there had been a fire in the fuse box. I took pictures of the charred remains of the fuse box, cover and connectors. Most of the plastic connectors under the fuse box could not be removed because they had melted and were fused onto the box. He noted the fire seemed to originate from fuse 46, the headlamp driver module. For the past few years, I had been experiencing headlight and tail light issues involving bulbs that were burning out frequently or were going out then coming back on.
