Official summary
Customer Satisfaction Program. Due to the industry-wide semiconductor shortage, the front driver and passenger seat cushion ventilation blowers are not functional on certain 2022-2023 model year vehicles listed above, built beginning March 30, 2022. Dealers are to replace the non-functional seat cushion ventilation blower with a functional one.

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.
