Wiper problems of the 2008 Cadillac SRX

At night I can't see out my window it's very dark and my headlights are very dim making it very hard to see at night. I have to put my high beams on to see. Also my strong is hard to turn when I'm trying to reverse or park but sometimes it's fine like their isn't anything wrong and when I'm when I'm driving it's fine. My horn and everything on my steering wheel stopped working all of a sudden. I went to my car in the morning to turn it on and my heated steering wouldn't work the cruise control no buttons worked plus my horn. On top of that I had my car re alligned because it kept feeling wobbly and it didn't work.

While driving on our driveway, (no trees, rocks, debris, etc) the center portion of the moonroof imploded into the car. The shade was pulled trapping most of the glass shards from entering the vehicle. Nothing could have possibly hit the glass and I was traveling 5 mph or less, coming to a stop at the end of our driveway. I have read many complaints online of this occurring and think it is a manufacturer defect as this portion of the glass covers the motors/mechanism that controls the moonroof. The temperatures were not extreme and the car had not been driven prior to the incident. We have owned the vehicle for almost 3 years and are now concerned about the other 2 glass roof panels being defective as well. A very unnerving experience and we are just thankful no one was injured, but could see the potential for injury.
