Official summary

Service Update. Certain vehicles listed above may have a condition in which ice or sludge can accumulate in the Charge Air Cooler (CAC) or Closed Crankcase Ventilation (CCV) system when driving in extremely cold weather conditions (-18°C (0°F) or less). Dealers will install a TCV thermal wrap and, if applicable, reprogram the Engine Control Module.

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.
