I searched this forum and didn’t see anything mentioned, so if you are having this same problem the goal here is to save you some time, or even if my information is flawed, please correct it for the benefit of others, well and me too.
Never the less, a few days ago I noticed my HA FordPass integration stopped working. This happened a short time (days) after adding the FordPass integration to a second instance of Home Assistant at another location. Other than the FordPass app on my phone and my HA integrations I have no other apps using FordPasses API.
I also found that when logging into Ford’s site I received error CSIAH0320E which means my account was locked and required an admin to reinstate.
The long and short of it is that Ford is locking accounts without any apparent warning (That I saw anyway) for what are apparently API access violations. There is a thread here that goes into more detail, you just need to sift through the rants of ticked off owners. The link I shared should leave you at a post detailing how to get your account unlocked. If you want some interesting reading, go to the beginning of the thread.
Basically you need to remove the HA integration, call the number listed in the thread following the dos’ and don’ts when on the call to avoid confusion and being sent down the wrong track.
Ford certainly could have done a better job of communicating with their customers vs just hard locking accounts with no explanation leaving customers having to figure our what happened by themselves.
Do I understand why they did this: Yes on several fronts
Security
Battery Drain
API abuse
etc.
Do I agree with how they went about it: NO!
HTH,
