Official summary
09132D - Customer Satisfaction Program (revised expiration date). The power steering cooler line may leak or split when the vehicle is started in cold weather. This would result in fluid spotting under vehicle when the vehicle is parked and a decrease in power steering assist. If enough fluid were lost, damage to the power steering pump could occur. Dealers are to replace the power steering hose assembly or a length of hose and clamps, depending on the engine size.

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.
