The 2023 GMC Savana has two recalls, the more serious being a transmission software error that can cause harsh shifting, sudden power loss, unintended deceleration, rear wheel lockup, or the vehicle moving in an unintended direction.
The second recall affects Savana Cutaway incomplete vehicles wired for an optional rear HVAC system. If that rear blower motor circuit is left unused with its connectors exposed, the wiring can corrode and overheat, raising the risk of a fire.
