Official summary

TSB: Some 2017 ? 2022 model year RX 350 and RX 450h vehicles may exhibit water leaking from the moon roof when going through a high-pressure rinse cycle car wash. In most cases, a small amount of water is either missing or bouncing off the rain gutter and dripping into the interior (center console, seat, driver, etc.).

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.
