Official summary

Emission Recall - General Motors has decided to conduct a Voluntary Emission Recall on certain vehicles with a 6.6L diesel engine. These vehicles may have been built with an incorrect hood vent that does not allow sufficient airflow. Dealers are to inspect the hood vent and replace if the correct part was not installed.

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.
