Shane, thank you for the response. The mileage is 12,555
The dealer is:

West Herr Buick GMC Cadillac of East Aurora
BuickGMCCadillac
Sales: 888-271-4352 | Service: 888-623-2033 535 Main Street, East Aurora, NY 14052

The smell is extreme, can you confirm it is not a health hazard? When you research mold on the internet there is nothing good that is reported.

I did notify the dealer that their implementation of the Service Bulletin was not successful, they advised they would contact GM engineering, in the meantime I am exposed to breathing in an odor from mold. My wife suggested I contact the National Highway Traffic Safety Administration so they can determine the safety of prolonged exposure to the foul air.

Regards,
Larry Szal
