I have a 2014 SRX which had a leak in the Sun Roof. The leak was fixed by replacing with a new sun roof.. Since then I have had a rattle in the sun roof when traveling of a bumpy road. The rattle goes away if the sun roof is open just a slight bit. I have taken it to the dealer 4 times to fix with no luck. What can I do next.

This is very frustrating........
