Summary

Emission Recall. General Motors has decided to conduct a Voluntary Emission Recall involving certain 2024 Model Year Chevrolet Silverado and GMC Sierra vehicles with a 6.6L diesel engine. The Engine Control Module (ECM) may not properly diagnose, may not set Diagnostic Trouble Codes (DTCs), or may not illuminate the Malfunction Indicator Light (Check Engine Light) if certain fault conditions of the Selective Catalyst Reduction (SCR or NOx) catalyst occur. Dealers are to reprogram the ECM and TCM.

Owners of these vehicles have filed 27 complaints in the fuel system category.
