I just removed the fuse for the DCM in my Subaru earlier today. Both because I don't trust Subaru with my data (the privacy policy says basically by existing in the cabin, you consent to being audio recorded and the recordings sent back to Suburu for any use Subaru might want to use them for) and because my car apparently can't go four days without being driven without the battery dying. I'm hoping the problem is parasitic draw from the Starlink DCM module thing that I just disabled.
If it's not that, I'll have to do more diagnostics.
There's a recall for that. They will replace your telematics module for free with a "bypass box", which preserves the function of the front speakers, which stop working when you pull that fuse. Sorry I don't know if this also ends the telematics phone home problem. This is specifically to address the battery drain problem. It fixed my similar battery issues.
Anybody know if it turns off the data uploads, or not?
I'm pretty sure my 2021 Crosstrek isn't in scope of that recall (at least as far as Subaru is concerned), but I'll do some more research. Thanks!
To fix the battery drain problem, you can add a jumper wire inside the main fuse box that makes it so the DCM is powered only when the car is running, not all the time. Details here:

Yeah, but I don't want the DCM to be powered/running when the car is running either because of the data privacy concerns.
