hey guys,
just purchased the 09 CLS 550 last week and I am quite impressed. One problem that I have encountered with the car happened a few days ago when I had the car washed at a "touch-less car wash". When the water jets went through the windows, I noticed water coming into the car from both the right front and rear windows (not a lot but water did get in). Went to the dealership yesterday and asked about it, the service guys told me that there isn't much that can be done. The windows on the CLS are frameless and due to the extreme pressure of the wash jets, getting water was inevitable. One more thing to add is that when raining or going through other wash systems without directing high pressure at the windows there were no leaks (only when the jets are hitting the window edges with extreme pressure did water get it) Wondering if anyone has had similiar problems. Thanks!

 

I would recommend washing it yourself in one of those do it yourself wahes. They work good for me. What color do you have?

 

Seems weird to me. I live in Budapest and bought a CLS 320 in October 2007. I would always get it washed in a high pressure car wash and never had an issue. Perhaps yours is extra high pressure, just make sure its not the dealer avoiding looking into something else. The CLS lowers the frameless windows when you open the door and then re-adjusts them when you shut the doors. Make sure that there is not some mistake which causes it to not fully shut the windows.
