Has anyone had this lovely experience of the sunroof opening when applying the brakes? It'll just jump up and down while I'm holding the brake pedal down or suddenly when I'm in traffic, it'll open in "Vent" mode (did I say that correctly?).

I saw the warranty history on this car and the only warranty work done on it was replacing the sunroof dial. I have to push the dial in now, in order to get the roof to open or close beyond 1/4 the distance.

 

Three months after I got my 2003 CTS (new), I had the sunroof switch/dial replaced. Pressing to close/open it was the temporary work-around I had, too. That was 5 years ago - it has been working fine since.

I've not had the joy/exceitement of it jumping when braking...

 

Thanks. Here's the fraking thing about it, it's already been replaced. I bought mine used a few months ago. It's an '04. I'm assuming yours was done on warranty?

 

Yes. Thankfully.
