General Motors and the automotive division of IMPCO Technologies are recalling 1,791 2011-2013 model-year Chevrolet Express and GMC Savana Cargo vans that have a compressed natural gas (CNG) fuel system installed as original equipment by IMPCO.
The fuel systems, manufactured Feb. 14, 2011, through February 20, 2013, have a fuel shut-off solenoid connector to the CNG tank that may corrode and form a short, the National Highway Traffic Safety Administration reported. Because a short at the connector may cause overheating, the condition increases the risk of fire.
