My JT is possessed

[TampaFred]

I guess it's the 2nd battery but the symptoms are a little different. The start stop hasn't worked for at least a couple of weeks and it's warning light has been lit. I don't care for the stop/start so ignored it. Then yesterday it started up fine, turned over normal so assume the battery's good. 10 minutes later I get the battery light on and a message to stop because it's about to quit. It wasn't kidding. The engine died. I managed to coast into parking lot. That's when things got really strange. The dask and the overhead cabin light started flashing, the wipers started wiping but real slow. Turning it on/off didn't change anything. I was able to roll down the passenger window but not back up nor would any of the other windows operate. I was able to start the motor but it ran rough and died. Another attempt and the starter kept running for a bit. AAA came pretty quick but by then it was totally dead. It's now at a Tampa dealership waiting it's turn. At least it has found it's name, Christine, although in the movie the car fixed itself.

Now you have a name for the sides of the hood.

Those are symptoms of battery issues. If the voltage drops too low, the computers operate very erratically, If at all.

Under warranty?
Take to dealer.

Out of warranty?
Do your research on replacing, disabling, or deleting the AUX battery and make sure your main battery is still good.

Near term, I'd try pulling fuse F42 to take the likely suspect out of picture until you can do more.

Dealer repaired under warranty. Replaced aux battery and a fuse that blew. Also found bad pin in a connector that they repaired. They didn't say what fuse or connector.
Thanks for the suggestion regarding pulling the F42 fuse. I made a note of this on the fuse cover

Also make sure you main was not messed up by this, we had the same happen but aux was recovered and the main battery had to be replaced due to low charge.

Glad you got it fixed. But as stated, this is NOT abnormal/different occurrences for a bad/dying battery.
