I'll skip ahead and tell you what you'll eventually find:

- Subaru has a fix for this issue.

- Subaru's fix has dealerships use proprietary software to put the DCM module into "factory mode" (suspended).

- It will also have dealerships physically disconnect the Starlink-related buttons (e.g. SOS), because if they're pushed it will "wake up" the DCM.

- There is no assurance the DCM won't wake up again on its own (it has its own backup battery which can fail).

- Getting dealerships to conduct the above fix is a giant pain in the butt, and they'll charge you hundreds of dollars. Few customers have even got that far, most just get an expensive "diagnostics" bill with absolutely nothing to show for it. Most won't do the repair unless you can "prove" a problem, even though it is more work to prove the problem than to proactively conduct the repair.

- Subaru won't release the software, so you can do it yourself.
