Panoramic Sunroof bonding and bolts loose causing constant horrific cracking/clanking sounds due to shifting of glass. Possible frame and airbag damage, possible glass falling, possible injury/accident/death. Can cause issues with airbags deploying and water leaks. Mercedes mechanic said it’s the worst case/noise he has heard in any Mercedes. Same make/year/model has been recalled in other plants. Also, walnut trim has faded tremendously.
