Service bulletin T-SB-0026-24 Rev1
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Some 2022 – 2024 model year Tundra and Tundra Hybrid, and 2023 – 2024 model year Sequoia Hybrid vehicles, equipped with a JBL® premium sound system, may exhibit a rattle or buzz noise when listening to music coming from the subwoofer located in the rear left luggage area of the vehicle. This can be caused by exposure to certain operating environments with high humidity levels. To improve the subwoofer's performance in humid environments, Toyota has revised the speaker cone material and shape. The condition can be resolved by replacing the subwoofer assembly with box.
