Official summary
DOORS LOCKED WITH REMOTE CONTROL INSIDE THE VEHICLE. The customer states that the vehicle locks itself when the last door was closed even though the remote control/display key was inside the vehicle. Sporadic interference causes the vehicle to revert to "outside detection" of the vehicle remote control instead of "inside the vehicle detection" which is where the key was located.

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.
