Official summary

This Preliminary Information communication provides information to the technician about vehicles that have rusty or corroded appearance on the exhaust components. This is a normal condition and these components should not be replaced for this surface or cosmetic corrosion.

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.
