Check Subaru TSB 15-312-23R…
Check Subaru TSB 15-312-23R Revision 06/28/23 This is for 16-18 Outbacks but I think it will cover 19's. I still have to check on that. The dealer can put the module to sleep and disconnect your sos and information button. If you wanted to use Starlink after this you would have to reconnect the switches, replace dcm and program. My vehicle was under waranty when they stopped the 3g service. Subaru should have replaced all the modules under warranty, not just if you had a Starlink subscription. Now I to have a battery drain issue too due the the module looking for the 3g signal. The TSB says its covered under a special policy. I have to stop by the dealer.
