GM Recalls Chevrolet Express and GMC Sierra Vehicles With Headliner Fire Risk
Affects vehicles equipped with a single, manual, rear climate control module
General Motors (GM) is recalling certain 2016-2018 Chevrolet Express and GMC Sierra vehicles equipped with a single, manual, rear climate control module (CCM). If the temperature is set to maximum heat or the mode knob is set to maximum floor vent and an electrical short occurs, components within the CCM may overheat, increasing the risk of a headliner fire.
What's the problem?
GM has decided that a defect which relates to motor vehicle safety exists in more than 30,000 Chevrolet Express and GMC Savana vehicles from the 2016 through 2018 model years equipped with a single manual rear climate control module (CCM) located in the roof console. In some cases, when the temperature is set to maximum heat or the mode knob is set to maximum floor vent and a short-to-ground condition occurs, the short may allow excessive current to flow through the controls' potentiometers and they may overheat. If this condition occurs, the terminal insulation on the CCM's potentiometers can catch fire. If this condition occurs, a fire may develop in the headliner.
An inoperative temperature or mode control in the rear CCM may indicate the fault is present
What happens next?
GM will notify owners and dealers will remove the electrical insulation from a wiring connector within the CCM to remove the fire risk at no charge. The manufacturer has not yet provided a notification schedule. Owners may contact Chevrolet customer service at (800) 222-1020 or GMC customer service at (800) 462-8782. GM's number for this recall is 18299.
