Toyota Tundra sinking dashboard issue with noise from passenger side near airbag on Toyota Tundra

Some Toyota Tundra owners report experiencing issues with sinking dashboards, where the dashboard warps and sinks along the length of the windshield. This problem appears to worsen over time, with the manufacturer indicating that it falls within specification compared to similar vehicles. In severe cases, the dashboard sinks enough to reveal an imprint of the passenger side airbag due to warping and sagging. Additionally, some owners report noises from the passenger side dash area, resembling plastic rubbing against other parts, particularly near the airbag. One user identified that a loose nut related to the airbag sensor was causing a rattle, especially in cold weather and low RPM conditions. To address these concerns, some users have implemented fixes such as securing a loose strip of double-sided sticky foam with glue to eliminate rattles, and others have used blocks of wood wrapped in duct tape to smooth out dashboard waves.
