Official summary
Some vehicles may exhibit a light resistance and/or an unusual noise when turning the steering wheel in either direction. This concern may be caused by insufficient lubrication of the gear due to uneven and deteriorated grease. To eliminate this concern, the production process for the steering shaft has been further modified.
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.
