Is this the same fix they would’ve done as part of TSB 18-011-23? Wondering if I’ve already had it done or if there’s more involved with this one.
I don't know. It may be targeting a different group of vehicles than what 18-011-23 applied to. You should be able to search your vin to see if this applies to your vehicle or not. If it does, it definitely wasn't what was performed on a previous tsb you received.

I only ask as the repair procedure sounds very similar. No recalls showing in the app or when I search for my VIN so may not apply in my case. Here’s the work order from that TSB completed on Feb 23 for reference:

Not a huge surprise since it's also a PCM reflash. We won't really know the answer to your question until someone with a 22 has the 23A update performed and can report the ecu software part number. Of course, even if it's different, it may be the same basic software load, just adapted to whatever difference it is that makes some 22s apply and some not. If I had the guess, I'd bet the 22s that 23A applies to are really late builds and are basically running the same configuration as the 23s, which is why they're separated... but that's pure speculation on my part.
