Eternal IBR Module issue

[Scuba boy]

I am fairly new to the PWC game and recently purchased a 2022 RXP X 300 with about 40 hours. I noticed the loose and corroded battery terminals when I first got it. I tested the battery and decided to replace it with a new MotoBatt. Even sanded down the wire terminals for optimal connection. Sent to the dealership where they did an IBR Update, which was needed, and went out only to have the same error come and go. It comes, then I have to kill the engine, then it disappears, and then reappears occasionally. Thoughts??
