I was driving in very thick fog which was a white out. I was going through a turn and was lost in the fog quickly and I ended up off the side of the road struck a speed limit sign and a utility pole on my drivers side door because I seen it at the last moment and tried to avoid hitting it. But at the point of impact my driver side airbag never deployed at all causing me to suffer numerous broken ribs and loss of work for over 2 months time.

2008 hummer h3 alpha with factory tow package trailer routed between sharp body panel and bumper causing vehicle motion to rub the wires. The exposed wires short to the body and cause high current melting interior wiring. This problem has been imntermittent for about 1 year and have had GM dealer troubleshoot the failure of trailer brakes and lights with no solution. I discovered problem by removing rear bumper. Problem can be avoided by shielding wiring and smoothing the sharp metal edges it crosses.
