Official summary
Some vehicles may exhibit a squeaking noise from the blower motor while it is operating. This is caused by burrs that were not trimmed completely in the manufacturing process of the blower motor. To eliminate this concern, the manufacturing process of the blower motor has been modified to efficiently trim burrs.

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.
