problem details
Both of my back windows leak when it rains or even worse if I wash it. It has been to the shop 5 times for repair and they haven't been able to get them to stop leaking yet. It is an obvious design flaw. I would like to see VW recall this and get it fixed!
Just purchased my CC w/44,500 miles a 2012 Lux Plus w/o backup camera. While washing it I noticed that there was water getting inside thru the back windows. What will VW service do to fix this.
