Presumably this is impacting hundreds or thousands of cars, right?
We called our dealer and service center this afternoon and explained the issue. Said there is a whole thread about it in Ram forums, and they made a quip about there's always noise on the forums. Asked them point blank if any other vehicles experiencing this issue and they said just one other. Don't want to waste time on a diagnosis that they won't be able to make, when they just need to better communicate and plan for a response to this incident. Until then, we deleted the app and also turned off automatic updates via wifi in the car itself. Driving fine since then, and keeping an eye on voltage via the dash. But certainly not taking it anywhere far until we know it's a reliable vehicle.
