What can fail
Exposed wiring and connectors for an optional rear heating and air-conditioning system can corrode and overheat when the blower motor circuit is left unused.
What the fix does
The 2011 GMC Savana has 8 recalls, the most serious involving fire risks from two separate sources: unused HVAC wiring that can corrode and overheat, and, on vehicles with a compressed natural gas fuel system, a high-pressure regulator that can leak gas near an ignition source.
On the brake side, two recalls address fluid loss from different points: rear brake lines on certain vehicles can abrade against a fuel filler hose clamp, and the right rear brake hose can chafe against the tire or wheel rim. Either condition can cause brake fluid to leak and extend stopping distances. The CNG fuel system also has a separate electrical concern where a connector short can overheat and raise the risk of fire. Turning to occupant safety, the front passenger airbag may not deploy in lower-speed crashes, leaving an unbelted front passenger with less protection. Vehicles equipped with a plastic-handle or push-button fire extinguisher may find it fails to operate when needed. A body control module software error affects the key reprogramming procedure but has no impact on driving safety.

What can fail
The body control module software may be incorrect, leaving the immobilization system inactive during the 30-minute key programming process. An unlearned blank replacement key could temporarily disable the immobilization system during this window.
What the fix does
General Motors updated the body control module software in all unsold and new vehicles to ensure correct programming.

What can fail
The fire extinguisher may clog and fail to discharge, or require excessive force to use. In some models, the nozzle may detach forcefully, potentially causing injury and making the extinguisher inoperable.
What the fix does
GM will provide a free replacement fire extinguisher from Kidde. Contact your vehicle manufacturer's customer service to arrange the replacement.

What can fail
On some vehicles with a hinged left rear door, the rear brake lines may rub against the fuel filler hose clamp due to insufficient space. This rubbing can damage the brake lines and cause brake fluid to leak, reducing braking power and increasing stopping distance.
What the fix does
Dealers will check the clearance between the brake lines and fuel filler hose clamp. If too narrow, they will replace the brake lines with a redesigned part that provides proper spacing.

What can fail
The CNG high-pressure regulator may leak natural gas. If gas leaks near an ignition source, fire or explosion could occur.
What the fix does
The dealer will replace the regulator.

What can fail
In a frontal crash below the air bag deployment threshold, an unbelted front passenger's head may strike the instrument panel above the passenger air bag. The panel may not absorb this impact adequately, increasing injury risk.
What the fix does
Dealers will modify the passenger instrument panel at no cost to improve impact absorption and occupant protection.

What can fail
The right rear brake hose may rub against the tire or wheel rim, causing it to wear through and leak brake fluid, which reduces braking power.
What the fix does
Your dealer will reposition and secure the brake hose away from the wheel and inspect it for damage, replacing it if needed.
