Official summary

17337 - Emission Recall. General Motors has decided to conduct a Voluntary Emission Recall involving certain vehicles, equipped with a diesel engine. The engine control module in these vehicles may not properly diagnose a fault in the exhaust particulate matter sensor. Additionally, a subset of these vehicles, certain vehicles, may in rare instances exhibit a condition in which the engine surges up to 2,800 RPM during vehicle coast or vehicle braking. Dealers will program the engine control module, and transmission control module when applicable.

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.
