The tailgate will not completely open and will not close completely. In most cases, the tailgate will release and open only a short distance before stopping. In some situations, a humming noise can be heard, but no activation can be seen.
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.
