2014 Yukon XL SLT. Whenever the vehicle is driven for more than about an hour I notice that the volt meter drops a good bit below 14 volts. None of my other GM vehicles do this (Corvette, Sierra dually). I don't notice it happening on short trips, like a grocery store run. Only on extended trips. I read the sticky on steady voltage - is this what I am experiencing? It concerns me enough that I took a photo of my gauge cluster.
Should I be concerned?
