Exterior lighting:headlights
General Motors, LLC (GM) is recalling certain 2010-2017 GMC Terrain vehicles. A reflection caused by the headlight housings may illuminate areas above the vehicle and outside of the driver's view with excessively bright light. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: The bright reflection may cause a glare for other drivers, reducing their visibility and increasing the risk of a crash.
Remedy: Dealers will install headlamp appliques, free of charge. Owner notification letters were mailed September 8, 2022. Owners may contact GMC customer service at 1-800-462-8782. GM's number for this recall is N222363740.
