Official summary

Dealer Message - Today, December 3, 2021, Acura is announcing a product improvement campaign (PIC) for certain 2019-2021 RDX vehicles to update the telematics control unit (TCU) software for an upcoming network service change. Perform an iN VIN status inquiry to determine which units in your inventory are affected.

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.
