Squeeky Roofs in '10 Grand Sports

[try2pas]

I am thinking of trying to buy a used '10 Grand Sport Coupe. Does anyone know if the "squeeky roof" has been solved by GM for the '10 Grand Sport? I know a lot of '08s have had this issue.

Even if it hasn't,and I can't recall,with a little grease in the right places the noise goes away.

I sprayed some WD40 on a rag and wiped the connection points with it and never had a issue again on my old 2008
