It sounds like the glass is gonna shatter, like steel is hitting the rear heated glass window---only happens when I raise the roof. I have inspected the panels before I hear the noise but can't find any wear or migrating steels parts.
It's really loud! Can anyone help me. Thanks and regards.
PS: This 2015 Mustang car is brand new at only 6900 miles so nothing appears worn or abused. No carfax, it wasn't an error on this six-digit odometer !
