Thanks! I love the X its one of my favorite SAV's and Ive heard about that and read it and i know it can be caused by short drives but i drive 20 mins to work one way twice a day all on the highway and alot of it cleared up weeks ago but it seems to have a appeared a bit again and i do alot of highway driving almost every day of the week for work, but it just seems like my coolant level will never stay full when i check it when its cold, it goes down but never to the point where it throws a low coolant light or overheating. im puzzled and ive just tuned up everything under the hood.
