Hello,

At the beginning of October, I had the battery in my 2016 Impala replaced (it was completely dead). Last Saturday, the wife and I were at dinner and I checked my email and the most recent monthly diagnostics report came over from Onstar and it said the battery was low. I then checked the previous two months (November and October) and to my surprise, there were also low battery warnings there - I completely missed those. The car seems to be driving fine and the battery light on the dashboard is not illuminated. Is this a false alarm or should I see about having it serviced? The only odd thing I noticed after the battery was replaced was that it was having troubling seeing my fob, but that issue seems to have resolved itself over the last few weeks.

Thanks!

 

is the onstar report for a low battery for the fob or vehicle?

 

It says “One or more items on this vehicle may require immediate service. Low battery.”

 

Any other ideas?

 

can you post the code that is setting.
it will be in the format starting will a p or b followed by 4 characters. ie p0016

 

IndyColtsFan,
I'm having the same issue. Battery replaced but monthly diagnostic report still says low battery. When I login on the site the alert is dated from right before I replaced it. I don't understand why it's still included on the report. Did you ever figure yours out?
