2011 Chevrolet Express 3500 Recalls
Certain vehicles equipped to run on compressed natural gas are being recalled because the high pressure natural gas regulator could develop a leak, increasing the risk of a fire or explosion. Dealers will replace the natural gas regulator to correct this concern.
Certain vehicles are being recalled because if a crash were to occur not requiring deployment of the front airbags, the head of an unbelted front seat passenger could hit the instrument panel, resulting in personal injury because the panel may not sufficiently absorb the impact. As of this writing, General Motors is still working on a remedy for this concern.
IMPCO Technologies installed a compressed natural gas (CNG) fuel system as original equipment on certain 2011-2013 full size GM vans. These vans are being recalled because the electrical connector on the fuel shut off solenoid can corrode, causing the connector to overheat, increasing the risk of a fire. Both dealers and fleet operators will be performing the necessary updates to correct this concern. The corrections include: replacing the fuel shut off solenoid, fuel pump fuse, and adjusting the wiring routing.
Certain 2011 Express vans converted by Impco Automotive to run on compressed natural gas may have a pressure relief vent pipe which may not have been built correctly. If venting of the natural gas were to occur, this gas could end up in the passenger compartment, increasing the risk of an explosion or fire. Impco Automotive, in cooperation with General Motors will inspect the pressure relief device and vent pipe assembly and repair them as necessary.
