GerryAZ said:I never noticed it on the 2011 because I did not monitor the 12V system while driving, but the 2015 and 2019 do run the system at 14V with wipers on (and for a little while after turning them off). I have not noticed the same voltage rise with just HVAC use (which is why I asked for your explanation).
I wrote that it was anecdotal because it was based more on descriptions of use patterns than of measuring system voltage. I'm surprised that specific device activation, rather than a drain of any sort on the 12 volt system, is required to increase charging. I guess I'll never understand Nissan engineering...
