Bulletin Summary
Emission Recall. General Motors has decided to conduct a Voluntary Emissions Recall on certain vehicles with a 6.6L gasoline engine (RPO L8T). In certain vehicles, water may enter the Mass Air Flow (MAF) sensor and cause it to fail. If this condition occurs, the Malfunction Indicator Light (Check Engine Light) will illuminate, a diagnostic trouble code will set, and the engine may run rough or be difficult to start. Dealers are to replace the MAF sensor and wrap the connecting harness with Tesa tape.
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.
