Bulletin Summary
Emission - General Motors has decided to conduct a voluntary emissions recall involving certain 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
