Official summary
Customer Satisfaction Program. It has come to our attention that some vehicles involved in the heated vented seat retrofit may also be involved in Noncompliance recall N222386380. If the OTA update is completed prior to the heated vented seat retrofit, the customer may notice the heated vented seat switch now illuminates. This OTA update does not restore the heated vented seat functionality. Completion of Customer Satisfaction Program N212354520 through N212354525 are necessary to restore the functionality of the heated vented seats. We encourage working with customers to schedule appointments

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.
