Official summary
Some vehicles may experience a condition where the engine does not start using the normal starting procedure and the doors will not lock/unlock when using a request switch. The engine will start if you touch the backside of the remote (1) to the push button start (2). This may be caused by water running down between the windshield and the dashboard resulting in corrosion of the terminals at connectors C-16 and/or C-04. To correct this issue, shield plates have been attached to the upper dashboard to prevent water from dropping onto these connectors.

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.
