Hello everyone. Looking for some clarity. My 2017 would not start, and after I checked the battery, it needed replaced. After I replaced it, I noticed that the voltage was fluctuating on the instrument panel. Got everything tested and shows good. I never noticed it before and wondered if anyone else has had this issue.

Thanks in advance for your time.

Welcome to the forum.
I suggest you read the section in your owners manual regarding voltage readings on the gauge. The fluctuation you see may be normal operation of the charging system.

Is your Acadia the 1st generation (Lambda platform) 2017 Limited, or the redesigned 2nd generation (C1XX platform) model?
