Official summary

Some vehicles equipped with a coolant control valve may exhibit difficulties when refilling the coolant because the control valve is closed and air in the engine cannot escape during ignition ON. Therefore, turn the ignition OFF when refilling engine coolant using the radiator filler neck.

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.
