This seems to be an update to TSB 22-2295, however it only applies to vehicles without 360º cameras built before 28-Oct-2022. I should mention the "Reverse Brake Assist Not Available" message at startup is normal after some updates have just been performed, and driving the vehicle for a few miles will clear it automatically. However if the message appears randomly while driving and you haven't just gotten a software update before driving it, then you should have your dealer apply this TSB. The IPMA software will be updated, and the cameras will have to be realigned (procedure requires driving around on a marked road and through a marked parking lot).
