Official summary
Emission - General Motors has decided to conduct a voluntary emissions recall involving certain 2017-2018 model year diesel engine vehicles. The engine control module (ECM) in these vehicles may not adequately diagnose or illuminate the malfunction indicator lamp (Check Engine Light) when frequent regeneration of the diesel particulate filter (DPF) occurs. Dealers are to program the engine control module (ECM) with corrected software.

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.
