3 horn (beeps) sounds when starting engine

What is your question?

About a month ago my 2018 Ford Fusion Hybrid Platinum started to make 3 consecutive honks at start-up. I have read that it may be a warning that the 12v battery was dying. Sure enough, after about 15 days, the battery died. I replaced the battery and thought the beeping (honks) would go away, but it has not. Also, when this problem started, the remote start is not working. HELP!!!!

What makes this problem better or worse?

N/A

How long has your 2018 Ford Fusion had this problem?

1month
