I have a brand new 2011 Cayenne with 200 miles on her. It was 95 degrees here in Washington DC area. The heat blew out the rear window...the car is black on black. The glass was intact with millions of glass breaks. No signs of anyone messing with it. Speaks to the quality (or lack of) in the glass, no?
As expected, the dealer says bring her in and get new Porsche glass under warranty. But I'm concerned of it happening again. Can't put her in the garage. Two other Porsches in there and 3 motorcycles. I know. Poor me. I wonder if anyone else had this happen.
