My 09 Targa glass roof and back window squeeks like crazy. Has any Targa owners have the same issue? I guess the glass roof is separated from the body using rubber.....

 

There are small connectors on the rear glass for the defroster, check those.

 

Just clean the rubber weatherstrips at front and rear edges of the sunroof. I spray silicone spray onto a rag and just wipe them. Always works on my targa.

 

I've got no issues other than a slight sound from the front rubber seal when driving on bumpy roads. I think the most common squeek source is the movement of the rubber seals against each other at the leading or back edge of the top, when closed. Some sort of treatment like a silicone spray applied with a rag probably works well.

 

Thanks... I will try Silicone and will check the connections...... I wondered why Porsche didn't resolve this issue.....

 

I believed that is the nature of the glass roof. My old 2006 E55 with glass panaramic sunroof squeak a bit and worst in the winter. Since I return my lease E55 I vowed not to get another car with glass roof.
