Just got my 2019 Ram big horn. Etorque. Got it used yesterday with 60k miles. Drove 50 miles, 3 times the 8.4 rebooted after the truck was already running. I thought, well that's weird but maybe I was bumping something I didn't realize in the new to me truck. Woke up this morning. Truck is clear dead, no lights at all. Took forever to get charged back enough to start.
Interesting to me, the usb outlet were not turning off like the ones in the front. Also the screen in the gauge cluster was not turning off. Even with truck off, door closed, key in the house, wait 30 minutes.....screen still on.
When I did get it running all kinds of stuff was messed up. You couldn't even set the temp. On the AC anymore, it would just say HI or LO.
Dealer took it back for repair. They said they out a tech right on it. Hope so.
