Affects GMC Savana · 2016–2018 — about 1K vehicles.
The hazard
On certain vehicles equipped with a single manual rear climate control module (CCM), the CCM could overheat when the temperature is set to maximum heat or the knob is set to maximum floor vent. If this occurs, the insulation material used on the CCM terminal connectors could catch fire, increasing the risk of injury and/or damage to property. Correction: Dealers will remove the insulation from the CCM terminal connectors.
