Official summary
Concern: Power steering lines may be leaking at the power steering rack. Work Procedure: The power steering lines at the steering rack may leak due to a damaged o-ring(s). The o-ring damage results from an imperfection in the line. Replacing the o-rings alone is not sufficient to repair the concern; the line must be replaced as well. Note however that it is not necessary to replace the steering rack.

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.
