2007 Saturn Vue electrical system problems

I was driving in my subdivision and the curtain air bags went off in my 2007 saturn vue hybrid. I swerved and ran into a tree causing massive frontal damage and the driver-side air bag to deploy. My 3-year-old daughter was in the back passenger child car seat and was ok but I was diagnosed with chest, knee, hip, and nose contusions, still healing after 4+ days. The car was a total loss per allstate. I have no idea what caused the curtain air bags to go off but see on carcomplaints.com there are many airbag issues.

Ignition key fell out of ignition while vehicle was in motion. It has happened several times since over the years. It can easily be removed from the ignition even when in the park position. Key can come out of ignition no matter if the key is new, a copy, or showing any wear. I have never kept anything other than one house key and the manufacturer's fab attached since I first took ownership of this vehicle.
