Whats wrong with my car?

Yah sounds like you have a short somewhere, or maybe several of them. You can do a visual inspection under the hood and under the dash and make sure there are no wires that looked frayed or bare. If there are wrap them with electrician tape.

As big a fan I am of General Motors products, they aren’t known for good electronics. The directional issue is probably a multifunction switch, which I have no idea how much that would cost. Replacing it would require removal of the airbag from the steering wheel then the removal of the wheel itself, some digging around inside the column and then the final pulling-and replacement of the switch.

The sunroof……. that could be a number of things. Either again bad electronics, or something mechanical is going on, like for example an arm that holds onto the glass rusted due to a leak around the window, and now it sticks.

Perhaps the weather or the angle you park at could affect it. There are a number of things that could be wrong. Humidity in the air, stuff like that. Take note of these things when you think to and present them with your problems to your mechanic; avoid the dealer they overcharge bigtime.
