Wow nice work -- in hindsight makes perfect sense I had noticed mine when driving down the highway at night, straight line. Let's hope your finding makes it's way to all the dealerships with a fix...I can finally replicate this problem at any time. The steering wheel to stalk has a "dead" zone that is so small that it seems like a flicker. I have a couple actually. One is like a mm from center, so when driving down a straight road, the very minute corrections on the wheel made it seem like a vibration caused short. Now that I know where the spot is, I can make the stalk flicker and go out at will. Someone had mentioned a dead area on the clock spring in the steering wheel could cause this? I'm scheduling an appt in a couple weeks. At least this time I can replicate it.
