I haven't figured out what exactly triggers it yet, but every once in a while when I go to make a harder than average turn the tilt column breaks loose and falls to the lowest setting. It usually happens at the most inopportune time, like when I go to turn into a parking lot while holding my coffee in one hand or when I almost missed my turn but saved it by making one of those frantic dives just in time. As best I can figure it only happens on sharper turns, but not necessarily hard turns; the turn into the parking lot was at low speed.
Any clue what's causing this? I don't have the standard wobbly wheel syndrome that you would expect with the tilt column; the wheel is still very tight.
