Hi: Bounty Hunter... I find this quite "Shocking"!!! I wonder if all my DEF Countdown kerfuffle is indicative of a weak Battery. It's still original from 2016. I maybe forced to seek the advice of the Stealership service dept. Just when I thought I had some money in the bank...OMG!!!The voltage is computer controlled. Until you throw a trouble code, all is well.
