NHTSA Complaint #11455779 — 2020 SUBARU ASCENT

During a camping trip the battery died when the tailgate was left open. Second battery incident: Went to go start my car after not driving for 6 days, battery was dead. No lights, doors, or hatch was on or open. After using a trickle charger I recharged the battery and was able to start the car after 4 hours of charging. After the car sat for one day the engine did turn over, but it sounded like it took a bit of extra effort for the starter to get the engine going. Third battery incident: I went to start my car again after it was parked for 5 days and the battery was dead again. I used the trickle charger again and was able to charge the battery to over 80%. The next day I took the car in for a service to investigate why the battery was draining to dead after not driving for days. The service department was unable to determine a cause of the issue. The battery was in good condition and was in the green on the grading scale.
