Bulletin Summary
15457 - Special Coverage. Some 2010-2015 Chevrolet Express and GMC Savana vehicles and 2011-2015 Chevrolet Silverado HD and GMC Sierra HD vehicles that are equipped with 6.6L Duramax Diesel engines (RPO LML or LGH) may contain a leak in the seal between the engine-exhaust down pipe and the engine-exhaust pipe. If a leak is present, the intermittent regeneration of the diesel-particulate filter may cause small amounts of diesel fuel to leak from the vehicle. It may also cause diesel-fuel vapor and engine exhaust to enter the passenger cabin. Dealers are to inspect the turbocharger exhaust pipe and the downpipe connection and implement service kit if necessary.
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.
