Official summary
When you insert the key in the driver's door lock and turn it quickly, the passenger's door may not lock and the security system may not arm. In addition, if you open the trunk and then immediately close it, the security system may not arm the trunk. This is caused by a timing discrepancy in the multiplex integrated control unit - product update. *tt

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.
