To make a long story short, the used 03' CTS that I purchased 5 weeks ago is the shop(for the second time) for the sunroof leaking. The first time it was magicly fixed they told me that the drains were clogged. This time they are telling me that the timing may be off on the roof itself. I ran it through the car wash after it was in the first time, and I had water coming in trough the airbag button located above the passenger side rear seat. I am looking for help to see if anyone has heard of this, or is it just attempt by the dealership to stall until the figure it out. Your help is greatly appreciated.
