Have had H3 intothe dealer at least 5 times with this problem.
Suggestions? Please.Thanks

 

My brand new 2008 did the same thing. Dealer did adjustments and fixed it. Make sure all 4 corners are flush with the roofline.Another problem can be stopped up drains. If it is still under warranty, I would work my way up the food chain at the dealership until I got satisfaction. If that doesn't work, call GM and complain. My dealer bent over backwards to make sure everything was right onmy vehicle.Apparently the survey GM sends out has a lot of clout. Itwas mentioned several times during my purchase. If it's not under warranty, a shop that installs sunroofs my be an option. I hope you get it fixed.
