Iím having this issue intermittently since 2013 and my battery is from 2010, yes itís been there that long. I donít have any tools to measure the voltage under the load so I run the onboard test. Turned the ignition on, without cranking go to sensor 24 and it was 11.4V, I started to crank and it went down to 8.9 to 9V, that was the lowest I caught. When the engine was running it reads 13.6 to 13.8 at idle.
I guess itís time for a new battery? I was at overseas in September and came back 3 weeks later and the car just fired up right away, for a 9 year old battery it was surprising.
