As of this morning, dealer still had not looked at it. I told them to hold off.
I rode my motorcycle to Costco and got an Interstate AGM. They only had the H7 AGM, no H8, so that's what I got. It fit in the side case on my bike. LOL Ratchet, extensions, and 10mm socket were the only other things I needed, which I took with me.
I went to the dealer, got they key, and put the new battery in right there in their parking lot. It cranked right up, but still showed the CEL and error messages. I drove it around in their parking lot for a few minutes. I shut it off, got out, locked it, waited a minute, then got back in and cranked it up again 2 or 3 times.
It shifted normally from the get-go. No more stuck in 1st gear. On the 3rd or so restart, all the error messages were gone and the CEL was off.
But, I still had the following issues, all with my 12" Uconnect:
- no backup camera (shift into R and Uconnect screen did not even change away from the media/radio screen).
- no 360 degree view camera
- no ParkSense braking (though the regular backup and front collision sensors still worked)
- Sync button in A/C did not do anything. I.e. on Auto, I could adjust the temp to any number I wanted, but the Sync button would not work to make the 2nd climate zone temp stay synced with the driver's temp setting.
- no controls for the power running boards
All of the icons for all those things were missing in the Uconnect display.
So, I left it at the dealer. But, they said that the reason they had not looked at it yet was they had it in the work queue for their transmission line (because it wouldn't shift out of 1st gear when I had it towed to them). I updated the service writer and he changed it to a new queue and they had it back in a service bay within an hour.
I suspect all it needs now is the Uconnect stuff reset. If all goes as expected now, they should have it done today.
Earlier, I had wondered if I would get charged for a tow if I just went and get the truck, but I realize now that was not a concern. The tow was covered by my Mopar warranty's roadside assistance deal. There is no charge for the tow on my ticket at the dealer. So, if the battery had 100% fixed it, I could have just left in it, with no charges at all.
