The 2021 GMC Savana has 4 recalls, with three involving electrical fire risks from wiring faults and a fourth covering tires that can fail suddenly at speed.
Two of the fire-related recalls involve the positive battery cable terminals making contact with the fuse block assembly, which can cause a short circuit and ignite a fire. These both affect the same area of the vehicle and only apply to trucks equipped with the 6.6L gasoline engine. A third electrical recall affects Savana Cutaway incomplete vehicles wired for an optional rear heating and air conditioning system: when that wiring is left unused with connectors exposed, the blower motor circuit can corrode over time, overheat, and also create a fire risk. On the tire side, certain Continental tires fitted to these vehicles can over-cure during manufacturing, leading to a sidewall crack, sudden air loss, or a tread and belt separation while driving.
