Wiring problems of the 2006 Cadillac SRX

At random the blinker and electrical system fail in my 2006 Cadillac Srx v6 awd. I was driving and turned on the blinker to make a turn and the blinker did not sound and did not function. This problem does not happen regularly it is a 1 in a 100. I have had my Cadillac in to a Cadillac dealer multiple times to have this corrected and I fear that more cars may have this problem and an accident may occur. At times where the blinker fails the radio also may skip stations.

Turned key to start truck, smoke came out of ac vents and steering column, acrid odor accompanied smoke. Shut key off exited vehicle, flames erupted in vehicle, called fire dept. They arrived 20 minutes later, car was heavily damaged. Vehicle towed to Cadillac dealership. Truck considered total loss. I sustained injury exiting vehicle , as I am 7 months pregnant.
