    Subaru of America, Inc. (Subaru) is recalling certain 2017-2019 Impreza vehicles. The left and right side reflex reflector and left side low beam reflector may inadequately reflect 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."
