I have a C6 Convertible, 2009. A few days after I got it, I noticed 2 small sips on the headliner of the car. One above my head and the other in the same spot on the passenger side. I had the dealer replace the headliner and thought did the repair to stop it. The car is currently at the dealer again for a second headliner, same problem. I was wondering if anyone else has had this problem. Any info would be helpful.
