Official summary
DP: A Toyota Genuine Accessory Dash Camera was installed in the involved vehicles.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
