If the Battery Saver Active light appears on your DIC (Driver Information Center) it is recommended that the driver reduce the electrical loads as much as possible. This message displays when the system detects that the battery voltage is dropping beyond a reasonable level. The battery saver system starts reducing certain features of the vehicle that you may be able to notice. At the point that the features are disabled, this message is displayed. It means that the vehicle is trying to save the charge in the battery. Turn off all unnecessary accessories to allow the battery to recharge. The normal battery voltage range is 11.5 to 15.5 volts. I would suggest that you contact your local dealership and have them look into this issue for you

Your battery may be getting weak, have it tested.

Did you ever figure it out? My 2014 Impala is doing the same thing.

I have the same problem and it's very intermittent. I think the most common cause it the battery cables and/or the small sensor attached to the two cable on the positive cable. Other things to to check would be your serpentine belt, battery, altenator, and of course the battery itself. I have 250,000 on my 2009 Impala - the car starts fine and runs fine so I think the sensor is the problem and I'm going to get it replaced (and possibly the cables as well). The problem seems to occur more frequently during warmer weather so I don't know. I was thinking it could be a problem with the computer but if that was the case then I think I'd have other issues. I'll update when/if I find the problem

My husband believes it the alternator so we'll replace that some time this week and hope it runs. Thank you

I "just might" have another answer. The intermiitent problem (Battery Saver Active) in my 2009 Impala seems to have mysteriously disappeared - as Iindicated above it "seemed" to be temperature related. I spoke with a few knowledgeable people and mentioned that I was pretty sure it wasn't the battery cables, alternator, battery or sensor and they said it still could be the alternator even though the AVR test passed - if there is too much heat in the area of the alternator that can cause problems .... now, I did replace my whole exhaust system because it was rusted out and low and behold the problem disappeared ?!?! Now, I'm thinking maybe hot gasses escaped upwards from holes in the exhaust and caused the altenator to occassionaly cut out. The car runs fine and the message is gone and hasn't reared its ugly head since then ; but I'm still holding my breath and not 100% convinced ( YET ). I'ts proving to be a very interesting and challenging problem. I have a long trip coming up and the weather is getting warmer so I'll keep everyone posted. I just love the car except for trying to track down the source of this problem but perhaps I have found whats causing it - perhaps ...... ). Any comments .........
