GMC Sierra: Fuel System
Affects GMC Sierra · 2015 — about 11 vehicles.
The hazard
On certain vehicles equipped with diesel engines, a hose clamp for the fuel tank vent line may not have been sufficiently tightened at assembly. This could allow the vent line to become detached from the fuel tank, which could cause a fuel leak. Fuel leakage, in the presence of an ignition source, could result in a fire causing injury and/or damage to property. Correction: Dealers will inspect and tighten the clamp as necessary.
