NHTSA Complaint #11315779 — 2020 SUBARU FORESTER

VEHICLE IGNITION IS OFF AND IN PARK. THE SAFETY ISSUE OCCURS WHEN THE REAR TAILGATE IS LEFT OPEN. AFTER 20 MINUTES OF LEAVING THE REAR TAILGATE OPEN, ALL THE INTERIOR LIGHTS TURN OFF CORRECTLY AS A PUBLISHED SAFETY FEATURE TO HELP PREVENT A DEAD BATTERY UPON DEPARTURE. THE USER THINKS EVERYTHING HAS SHUT OFF WHEN THE LIGHTS TURN OFF, HOWEVER, THE REAR TAILGATE ECU DOES NOT TURN OFF OR GO TO A LOW POWER STATE AFTER THE INITIAL 20 MINUTES CAUSING A HIGH DRAIN ON THE BATTERY. THE HATCH ECU CONTINUES TO DRAW IN EXCESS OF 4 AMPS WHILE THE HATCH IS LEFT OPEN, CAUSING A DEAD BATTERY IN AS LITTLE AS A FEW HOURS. THE USER CAN UNKNOWINGLY BE LEFT STRANDED WITH A DEAD BATTERY CAUSING A SAFETY ISSUE. THIS IS A SERIOUS OVERSIGHT AND ENGINEERING ERROR THAT WILL LIKELY LEAVE MANY PEOPLE UNKNOWINGLY STRANDED WITH A DEAD BATTERY.
