Condition
General Motors has decided to conduct a Voluntary Emission Recall involving certain 2010 model year Chevrolet Express, Silverado HD; and GMC Savana, Sierra HD vehicles equipped with a 6.6L V8 Duramax diesel engine (LMM); and 2007-2009 model year Chevrolet Express, Kodiak, Silverado HD; and GMC Savana, Sierra HD, and TopKick vehicles equipped with a 6.6L V8 Duramax diesel engine (LMM) that may have been serviced with a suspect Exhaust Gas Temperature (EGT) sensor. On these vehicles, the circuit board welds on the EGT sensors in the exhaust system may not be to GM specification. If a weld fails, the Service Engine Soon light will illuminate in the instrument panel, the exhaust gas may not be filtered properly, and the engine power may be reduced.
Correction
Dealers are to replace both EGT sensors, on all vehicles except chassis cab vehicles. On chassis cab vehicles, dealers are to replace only the position 2 sensor.
Vehicles Involved
Involved are certain 2010 model year Chevrolet Express, Silverado HD; and GMC Savana, Sierra HD vehicles equipped with a 6.6L V8 Duramax diesel engine (LMM); and 2007-2009 model year Chevrolet Express, Kodiak, Silverado HD; and GMC Savana, Sierra HD, and TopKick vehicles equipped with a 6.6L V8 Duramax diesel engine (LMM) that may have been serviced with a suspect EGT sensor.
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Required Field Actions section in the Global Warranty system. Not all vehicles may be involved.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall.
Parts Information
Parts required to complete this recall are to be obtained from General Motors Customer Care and Aftersales (GMCC&A). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.
