Official summary
This bulletin describes a design change to the center bracket component of the window regulator assembly. The change was made to address customer concerns of the front door glass shuddering while opening or closing. Moisture accumulation in the run channels can cause a stick-slip / vibration condition as the glass goes up and down resulting in the shudder.
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.
