- 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.
Owners of these vehicles have filed 288 complaints in the engine category.
