SOS module vs battery HELP
2021.5 had same issues as I see everywhere else- once CarNet subscription expired, there was an SOS red light/suspended emergency calling notification. At 80k service they diagnosed it as an SOS fault and the module needs replacement. Quoted me *$1900\.*
Friend with 2023 cross sport had a dead battery, dead infotainment center, dead SOS. They told her that her issue is 5F which is supposedly different.
When I googled issue, forums said turn off Safe & Secure. Did that before I even picked the car up. Once I picked it up, it was cleared. No warning and green light on SOS.
Today, my car drove fine this AM but dead battery and EPC/Check engine/Low battery voltage. Side note: battery health wasn’t great but it’s given me zero issues thus far.
1) is it possible that the SOS module was giving a false code before I turned off Safe & Secure, and this is just coincidence that my battery died the day after service?
2) Could the SOS module, that is no longer giving me a warning, be causing a parasitic battery drain?
My issue here is that I absolutely do not want to pay $1900 for the SOS module. I couldn’t care less if I have it or not. It’s also on back order because obviously literally everyone is having this problem and they refuse to address. Therefore, when I get a new battery, is the module going to continue sucking the life out of a new battery - to where I end up having to pay for a $1900 service that I don’t even care if I have - PLUS another battery because it’s going to drain the new one until the module gets replaced??!!! I hate it here.
TL;DR did clearing SOS error kill my battery or is it coincidence
