Why do I keep getting the message "Battery Voltage Low" on my 2012 TL even after battery replaced?

Asked by Feb 03, 2015 at 02:23 PM about the 2012 Acura TL FWD

Question type: Maintenance & Repair

I have a 2012 acura tl and 2 months ago the battery was dead and needed a jump.  Got it started and after driving on highway for a while to charge battery I get the message "Battery Voltage Low, turn off all electronics"  I brought the car to the acura dealer and they replaced the battery on Jan. 5, 2015.  Not even three weeks later I start getting the same message every time I shut the car off.  The dealer checked and says the alternator is putting out 14.27V no load and 13.62V load and that this is normal and says nothing is wrong with charging system and they also found no current drain.  If nothing is wrong then why do I keep getting these messages?

There is an update to the firmware that is available. I bought a used 2012 TL last year and it had the same issue when they prepped the car. The tech had seen the issue before and was able to reset the software and correct the problem. No problem since. The dealer should be able to check their service bulletins to find the fix.
