My acura mdx 2011 has been giving warning signs of battery replacement even when the Battery is ok as well as the alternator.
at times the battery indication flashes at times

I had a "check charging system" light on my 11 MDX when I purchased used back in 14. The dealership did a firmware update and that corrected the issue. The only other time I got a warning was when my OEM battery was slowly giving out after 4 years in the vehicle. Replaced it with Interstate and zero warning in +5 years.

You might have to take it in to check your cables for corrosion, load test battery if you are +4 years, alternator output voltage, and ground wires.

Hi, did you get a solution to the problem you were having with your mdx? I am currently having same issue even after replacing altenator and new battery.
