Electrical System problem #1

Driving down the road and I got a service trailer brake code pop up and would not go away and kept dinging it is very distracting and sometimes causes the trailer brakes to malfunction.

Electrical System problem #2

I had the rear defrost running, and began to hear a sizzling/hissing sound in the back seat. After a minute of hearing this noise, I noticed smoke coming from the rear sliding window. I immediately turned off the rear defrost. A few seconds later, I heard a loud pop and the passenger side of my rear window was shattered. I called and spoke with the dealership and explained what had happened. They said they knew exactly what had happened and it is pretty common in these trucks.
