I have a 2018 Silverado. I replaced the battery last fall and each onstar diagnostic report afterwards warned that my battery was low. I took it to my Chevy dealer and they said the batter is fine. Is this a know issue?

Welcome to the site.

 

Sometimes it takes forever for the messages to clear from OnStar, no idea why. Had the battery changed in our Tahoe early last fall, message finally stopped showing up this month.
