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.
The 2015 GMC Savana has 4 recalls, the most serious being two separate fire risks from electrical faults: unused rear HVAC wiring that can corrode and overheat, and a driver's power window switch that can corrode internally and generate enough heat to ignite.
The rear HVAC wiring issue affects Cutaway incomplete vehicles where the optional rear climate system was wired but left unconnected, leaving exposed connectors that can corrode over time and overheat in the blower motor circuit. The power window switch concern applies to vehicles equipped with power windows, where liquid intrusion causes internal corrosion that raises electrical resistance to the point of generating heat. There is also an equipment concern: some vehicles were shipped with fire extinguishers that may fail to discharge properly, leaving the driver without a working tool if a fire breaks out. On the chassis side, certain Savana incomplete vehicles built on the 159-inch wheelbase were delivered to final-stage manufacturers without a tire pressure monitoring system installed, meaning the driver receives no warning if a tire loses pressure and the vehicle is being driven on an underinflated tire, which raises the risk of a crash.

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
These vehicles were shipped without a tire pressure monitoring system (TPMS), which monitors tire pressure and alerts you if a tire is underinflated.
What the fix does
Dealers will install the TPMS hardware and software at no cost to fully equip your vehicle with this safety system.
