There have been isolated reports of an inoperative remote engine start (RES) fobs on 2017 and later Subaru Impreza vehicles, where the blue LED does not illuminate when pressing the start button. The cause of this is a dead battery in the fob itself, due to a software error. The affected RES kits are H001SFL000-2017 (Impreza with push-start ignition, and H001SFL100-2017 (with turn-key start ignition).
