The 2022 GMC Savana has 3 recalls, the most serious being a transmission control module software error that can cause harsh shifting, sudden rear wheel lockup, or the vehicle moving in an unintended direction, all of which raise the risk of a crash.
The remaining recall affects Cutaway-configured vehicles equipped with wiring for an optional rear heating and air conditioning system. When that blower motor circuit goes unused and the connectors are left exposed, the wiring can corrode and overheat, creating a fire risk.
