sticky ignition switch

[Yaristeve]

Does anyone else's ignition switch hang up in the "Start" position? Twice now, the switch has stuck in the Start position and the starter kept spinning even after I let the key go. I then have to turn key back manually.

Seems to happen only when it's cold. Grease getting gummy when it's cold? Worth taking to dealer?

I have been experiencing the same problem since the time got colder. Took it to the dealer and they said it was the grease in the switch/key barrel, which overtime hardens during cold weather. He recommended adding a small amount of heat carefully (with battery disconnented) to the switch and toggle back and forth with the key in the ignition to loosen up the grease inside.
