Official summary
Some of the above vehicles may experience a condition where the underbody transmission tunnel shield may partially separate from the vehicle floor pan and contact the aluminum driveshaft. Operating the vehicle with the transmission tunnel shield rubbing against the driveshaft could weaken the driveshaft at the rub point and cause it to break.
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.
