Noticed the other day while I was driving in the rain that there was alot of water on my headliner in each back corner up top of back seat. Took it to dealer they resealed the entire back sliding window. Checked under headliner for any rust or damage and it was fine. They sprayed water on it for about 5 minutes from a garden hose and it fixed the issiue . Thankfully still under warrenty . Just passing it along. They told me the original seal seperated from the window on each top corner thats were the water was coming in.
