I have been getting small static shocks when exiting the vehicle and touching the door metal when closing it.

I don't remember it happening when it was new (just over a year ago), and only noticed it over the winter. I figured it was static electricity from wearing sweaters and extra layers during the winter. However, today it was warmer and I had no sweater or layers, just jeans and a short sleeved shirt... same shock.

But I've never had anything as severe as you've described.
