2023 RAM 1500 Classic
Been driving this truck for about a month. Truck has some intermittent voltage issue and it shows up about once or twice a week. the reported voltage quickly fluctuates between 12V and 16V on dash cluster and the all the electronics go haywire until i restart the truck.
when it happens i'll notice because the dash lights, headlights and a/c stops working in the way that they should. brightness falls to like 80% and is very unstable. feels almost like its got a bad ground. a/c rapidly switches from on to off every few seconds. doesn't seem to matter if im driving or sitting idle. i cannot recreate the issue, it seems to happen randomly. shutting the truck off and waiting restarting makes the issue go away.
other observations, possibly related -- i get a warning on the dash that says "park assist disabled - service electronic braking system" with a small light that appears on the gauge cluster. this also goes away on its own but revisits me a few times each week.
last observation, probably not related but what the hell. the fuel gauge is off by at least 20%. i''ve run the truck "dry" twice now, both times I had "90 miles left until empty" and a little under 1/4 tank showing on the needle. I now fill up at 1/2 tank until i figure out what needs fixed.
when my truck was spazzing out earlier today, there was a moment that i thought i saw it flash "LOW FUEL" on the dashboard. first time i'd ever seen that. got me starting to wonder if maybe there is a common denominator to these issues. anyone got any thoughts ?
