I'm a new 2011 cts Cadillac owner. Have only had this car since Oct. 2014. My ceiling is leaking! Took it to the dealership and of course my certification doesn't cover the $130 I paid the specialist to LOOK at it. And they quoted me $965 just to fix it. I'm so upset! Apparently it's clogged for the drain pipes and the sunroof needs to be resealed. Ugh.
