Complaint Summary
ELECTRICAL SYSTEM
Owner Narrative
There is a current drain (approximately 135mA) by the built-in telematics system (DCM) even when the car is completely powered off. The drain will drop battery voltage levels beyond recharge/repair. Dead batteries can leave people stranded in unsafe areas or make them susceptible to potentially dangerous situations such as being approached by bad actors. The vehicle has been inspected by me, who confirmed the current draw through a multimeter and pulling fuses 1-by-1. It has been confirmed by multiple people online with similar symptoms: https://www.subaruoutback.org/threads/dark-current-drain.550299/ https://www.reddit.com/r/Subaru_Outback/comments/zzh5d3/drained_battery_and_dcm_fuse/ http://www.subarucomplaints.com/battery-drain/ No warnings, messages, or symptoms. Just kept waking up to dead batteries.
