NHTSA Complaint #11446280 — 2019 SUBARU OUTBACK

Parasitic Battery Drain left battery dead and unable to start vehicle. This was caused by a defective DCM (Data Communication Module). This problem first surfaced within weeks of new car purchase and took about 6-months and several visits to dealer to remedy. I also replaced the oem battery with a new upgraded battery at my own expense. Recently the problem reoccurred as the DCM module again failed and created a parasitic drain. This has probably damaged the new battery which is only a year old as it was completely discharged. The dealer again fixed the problem but as before was initially skeptical that it was caused by user error or letting vehicle sit too long between use; both of the most problematic failures occurred when the vehicle was left parked for 2-weeks at parksleepfly hotels while on trips and returned to find dead battery.
