I was having the "Headlight Leveling" Warrning message appear intermittedly. I haven't noticed my lights go up and down for a few months ( I mainly drive during the day). The Warning Light appeared on the first really cold day we had in Ohio 22 degrees. It also seems to happen under cold and wet conditions. Tonight I turned on my Headlights prior to starting the car and the lights went up and down and self leveled, So far I haven't had the Headlight Leveling warning light return. I hope this is the fix.
