Official summary
This Service Information bulletin announces a design change made to the TGV assemblies used on the Forester Turbo models and WRXs listed above. Condensation resulting from EGR system operation may enter the area between the TGV shaft and bearing. Over time, corrosion can develop and impede movement of the TGV shaft and cause any of the DTCs P2004, 2005, 2006 and /or P2007 to set. The material of the TGV shaft has been changed to stainless steel to optimize corrosion resistance.

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.
