It started this spring. My sunroof appears to be stuck in some way. It does retract, but it sounds like it's getting caught on something. I don't recall the car changing shape in any way over the winter, but something is obviously wrong with it.

Another thing I noticed even more recently is that my sunroof is closing itself when I turn off the car.

This should be very puzzling, except for 2 years it hadn't been doing that and I'd always have to turn the key back and shut it. I mean, it's convenient, but I left wondering if it's broken right now and it shouldn't be closing itself, or if it was broken for 2 years and I never knew.

I guess the only way to find out is to take it right into the belly of the beast and ask the people who installed it when I got the car.

addendum

My car has added a new feature. When I turned the car off, the passenger shouted "oh shit" because she had forgotten to roll up the window. So with the keys in my hands, she proceeds to roll up the window (automatic windows). I'm sitting there astonished, because yet again... my car never did that before.

I have no idea what's going on.
