Just happened to me today. Truck has been sitting in the garage for over a week with no fob in it. Went out to start it today and battery was dead. So dead, in fact, I couldn’t even get it to hold a charge with a charger and it absolutely won’t start. Called Roadside and they are on their way to pick it up. There may be 500 miles on the odometer.
Mine is as well
Same thing happened to me. Sat for four days, went to unlock my truck, battery was completely dead. Had to call RA.
Sounds the same. The tow truck driver said the service writer at the dealer said this was the second one this week with the exact same issue. I’ll update when I get some info on Monday.
I’m not positive. I think it probably is. Most of these first trucks were and were sitting in a yard waiting for final quality and software updates once they got enough miles on the pilots.
That’s a sound idea. After my dead battery incident, I charged my battery overnight. After almost a month, I haven’t had an issue; however, my start/stop hasn’t been working lately and I get the “vehicle is charging” message. It’s also the dead of winter with temps in the low teens and single digits. That doesn’t help.
I wish my auto stop/start would stop working but I have to disable it each drive. With my battery issues, I'm afraid the truck won't restart at a stop light.
The auto/start stop will not function if the system knows that the battery is not up to the task. You can see the message on the instrument cluster that reads “vehicle is charging”. Trust me, I am all too familiar with this problem. My 2018 did this most of the time and my 2021 is doing it right now.
