Official summary
Flash: Front Defrost Button Does Not Respond At Times This bulletin involves selectively erasing and reprogramming the HVAC control module with new software. Customers may experience a situation where the touch screen climate controls may ignore the first press of the front defrost button if it is the first climate button pressed after ignition ON. The second press of the front defrost button works correctly. If another climate button is pressed prior to the front defrost button, then the control will respond as desired.

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.
