FWIW i never replaced the 3g box in my 2018 subaru, and never have a battery drain issue. the battery did fail about 4 years in to owning the car, but it was a cell failure not a drain issue.
- pfooti 2y agoMy Subaru, a 2018 outback, would be completely battery dead if I left it parked for more than a week or so. Happened once at the airport, after which I started carrying a battery pack car starter. The guy at the airport who have us a jump said it happened all the time with Subarus in long term parking.

- reginald78 2y agoMy local mechanic said that there is a firmware update that supposedly fixes the radio drain last time I replaced the battery but I haven't looked into it. He primarily works on Subarus and it sounded like he'd seen that as a root cause of dead battery a lot.
- Melatonic 2y agoIs that firmware update also just replacing the 3G SIM though with a 4G one? In that case it will just fix the issue of it not being able to contact the cloud servers. Also makes me wonder - what if someone has a subaru and lives out in a very remote area where there is no 3G or 4G service? Would that not have the same issue as the cell towers being deprecated for 3G? Seems like (specifically for Subaru owners) this might be a more common type of living situation than other car owners too!
