2012 GMC Savana 1500 RecallsNatural Gas Leak
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.
The steering gear pitman shaft may not have been adequately hardened and could break. If this occurs, a loss of steering ability will result, increasing the risk of a crash. Dealers will inspect the steering gear and replace the steering gear pitman shaft if necessary to correct this concern. The General Motors recall number is 12005.
