I have a 2008 that has the sunroofs. I have owned for almost a year now and my vin number does not fall into the recall about the tubing. My acadia is garage kept and is rarely ever been out in the rain except 10 - 15 times at the most. I wash it often and have never seen any leaks. Just wondering if I should still be extra observant about this issue or not? I would think that washing and spraying water on and around the sunroof would make it leak if it was going to do so. I have noticed that the drain tubes work well because you can actually hear the water coming out of them when I wash the roof.
