2013 GMC Sierra 3500 HD Recalls
On vehicles equipped with a 6.6L diesel engine, the engine could stall unexpectedly due to an incorrect fuel gauge reading.
The label that indicates that only Compressed Natural Gas (CNG) fuel is to be used with the vehicle is too small, and does not meet federal requirements. This could lead to unsafe fueling practices.
Affected vehicles may be shifted out of Park with the ignition key removed or the ignition in the "off" position. As a result, the vehicle may roll unexpectedly, increasing the risk of injury or a crash.
