I had a similar issue where the transmission problem and blind spot warning lights were on. It happed after backing up for a long distance. My wife who had never driven the car before had a hard time putting it into reverse but finally managed. Immediately after I took over the wheel, I noticed all these lights. I took it in for service and immediately the service manager told me it was probably debris that entered into a small opening in the console where the reverse button was. He said that debris gets in there preventing the button from fully returning to its resting position. He was right. They found a small plastic diamond in there from a kids costume. After removal, all the lights went off. No charge! Apparently this is a very common issue. So before anything else, I would suggest that you have this area checked and cleaned if necessary. By the way, I keep my car immaculate inside, so this is not due to messy drivers if you will. They need to put a screen in the opening to prevent debris from entering.
