General Motors LLC (GM) and IMPCO Automotive Division of IMPCO Technologies, Inc. (IMPCO) are recalling certain model year 2011-2013 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 February 14, 2011, through February 20, 2013, have a fuel shut-off solenoid connector to the CNG tank that may corrode and form a short.
A short at the connector may cause overheating, resulting in an increased risk of fire.
GM will notify owners and GM dealers/fleets will perform the remedy which will include replacing the solenoid assemblies and fuel pump fuses and adjusting the wiring routing. An owner notification schedule has not yet been provided.
