Other Fuel System Tank Mounting problems of the 2008 Toyota Tundra

Frame mount for gas tank has rusted and fuel tank is dropping down. Last year an undercoating was applied by a Toyota dealer and is peeling off in certain areas. I believe pursuant to the class action lawsuit referred to as brian warner et al Toyota motor corporation my vehicle may be covered under warranty because the gas tank strap mounting is part of the frame. As of now, my mechanic advised me not to drive it as it is a safety hazard. I noticed the tank strap was hanging down from the frame and the gas tank was also hanging down while the vehicle was parked in my driveway.
