GMC Savana 3500 Recalls
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.
Chevrolet Express and GMC Savana vans are used by the Explorer Van Company as the base vehicle for some of their van conversions. Certain Explorer vans are being recalled because the wiring under the power seats may not have been properly secured during vehicle conversion. The wires can be damaged by the seat mechanism resulting in an electrical short and possibly a fire. Dealers will inspect and replace any seat wire harness found to be damaged. If the harness is not damaged, it will be secured to prevent future damage.
