Service battery
I have a 2012 Chevy Impala LTZ. A couple
days ago I started to get a message on the
dash that said “service battery charging
system” with the red battery light coming on.
I’ve had my battery and alternator tested. And
was told they were good. So I replaced 3 of
my actuators because they had been
knocking even when the car is off so I thought
that was the problem. But the light still comes
on. And today I got a “battery saver active”
message. Not really sure what to do
