This will lead to the vehicle entering a failsafe driving mode in which the vehicle can still be driven for certain distances.

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.
