If this is the original battery, I would replace it. I used to own a 2012 Impala LTZ and replaced the battery after 3 years. It is easy to change, but you have to remove the brace and loose the fuse box.

 

lol yeah it's easy as long as it isn't -40 out like when mine went out....then it was hours of pain in the rear trying to get it out of the hole it's in.

 

Question is.....was this a fluke? Even though the checks are fine on the battery and alternator, is it possible they still are failing? Am i missing something else that should be checked? Or should I just take it in to get it checked at the dealer?

:beer:

Run it to an auto parts store or wal mart auto center and have them check the battery. They can check it in the car and save you a load of money over the dealer.

Swapping the battery in the 12 is not too bad, but would be sure it is bad before just changing it.

 

Interesting video on that very thing just posted on PHAD

Would also remove battery terminals and clean posts and terminals.
DO NOT LOSE the little nut from the terminal. You will be very sad.

 

Most likely your battery is failing since the problem came and went. Most alternator problems start and stay.

Though a different year than your back in 2004 my "Gen" (alternator) light came on during a trip. Cycled the AC off and back on which turn off the Gen light. Tested it over the next 2 weeks trying to figure out whether the battery or alternator was the problem. Did not have a battery load tester or the electrolyte tester at that time. Just 2 days after the last check the battery had died.

 

Get a high capacity replacement battery and change it. Your car is 5 years old and that service charging system message is the car's way of telling you that your battery is going to fail. Better to change it now, then wait until its snowing and have your car die. You can also try trickle charging it and see if it stops. Also, don't lose the battery terminal nuts, because they are special nuts that tighten and lock in place.

 

Today while sitting parked in my 2012 Chevy Impala LS 83,000 miles, "the service battery charging system", "battery light", and "battery saver active" notifications came on. I had just driven 30 miles to work with no issues, nothing out of the ordinary. Now the car wouldn't start, just as with any "dead" battery. I went back out 2 hours later and it started up no problem, the alerts were gone, and just the check engine light came on. I drove it to the dealer, who didn't have any appointments until the weekend. So I went home (another 30 miles with no issues) and checked the the battery and alternator, and both checked perfect with the multi-meter. While starting the car to test the battery, the check engine light went off also.

I am having this exact problem from the first sentence right now. 2012 Chevy Impala. Replaced the battery a couple of years ago. I took it to the garage and they didn't have the problem, and said the battery was charged perfectly, so no problems there. Wondering what your ultimate resolution of this was. I am searching the internet and seeing people tell tales of woe about replacing the battery, replacing the alternator and still having problems...

I've been having the exact same thing happening to my 2012 LTZ. I installed a new alternator and new battery but just a couple months later I received the same in the interior alerts system. I checked the alternator while running...fine took the cables off the battery and still fine but when I asked a neighbor for a jump start it melted my brand new cables. I checked the ground and positive cables to the battery and everything is tight?

wats going on is 😩coooooompUtrrrzzs✋😒..

 

Did you ever find out? I have 2011 new alternator new power steering belt fluid and wasn’t turning over even with a jump. So I had the battery replaced and it wouldn’t turn over (like a totally dead battery) a few hours after same day they put in the new battery.

 

Your Impala has a battery voltage sensor on the red POS cable near the battery. There are sensor manufacturer documents in my personal help file just scroll down a little. Plus my notes for my 2010. It's possible the sensor has failed and therefore the Module will not instruct the alternator to provide adequate voltage. Sometimes this happens with no OBDII code and / or no CEL.

It possible to test the sensor AND test the wires from the plug back into the harness in case a wire is compromised.

You could have 2 troubles. A voltage sensor circuit and / or a failing starter solenoid or a loose wire at the solenoid.

If these items test prove good to go, then do a driveway PARASITIC DRAIN test. There's a neat help file and a help-form in my help files too.

 

Iv noticed 99.999999% of these types of problems often end up being a weak or corroded connection to 1 of the power lines - you could end up replacing all electric parts, entire car, & even rebuild entire planet, but that 1 cent snafU could still be there👋😑

 

Thank you so much. When I see my mechanic I’m going to pass on all of this great info. Thank you!

 

Thank you very much! I will show this to my mechanic when I see him soon!

 

gS Ur probly kiDng -bt U’r mech. is the 1 prsN on plNet that problE alreD nU👋

 

No, I meant to specifically tell him about the wires/connectors, because, as you and others have said, it seems to be one of last things that is figured out. (Would be nice to do the more likely, and less expensive things.) I’ve already replaced batt, alternator, next in line is the starter, but no point if it’s a connection or wire like you said!
