NHTSA Complaint #11483544 — 2020 SUBARU OUTBACK

I have had the battery be completely drained overnight for no apparent reason. Last year I took the car in 3 or more times for the dealer to diagnose. They gave me a new batter and said it was the parking break draining the battery. This year (almost a year later) the battery is again being drained. When the roadside assistance came to jump it he said the battery (after the jump) was only 3.9 volts which is much lower than anything like interior lights being left on would do. i'm worried that they haven't fixed this mysterious drain on the battery. And I see that there has already been a class action suit against Subaru of America (SOA) has been battling an issue with drained batteries on the Outback and Ascent SUVs. The original lawsuit from 2020 against SOA alleged the SUVs had defective electrical systems causing premature battery failure. A second lawsuit in 2021 against Subaru claimed defective electrical components in the Subaru Forester, Outback, Ascent, Legacy, and WRX vehicles.
