I've already tried the owner's manual, went to the dealer (useless), so now I'm here. In January the colors of the lanes (for the notice of lane departure) changed from white to blue. Then sometimes they go back to white, and sometimes one is white and one is blue. The other day, they were blank and there was a white bar at the front of the car icon. At around the same time, the Vehicle Dynamic Control popped up as OFF, but then went away after a second. It comes on every now and then, going off quickly. The dealer says they couldn't find anything. Help?
