UPDATE FIRMWARE PROBLEMS

[RamIt]

OK not to self.

When testing your batteries start the truck and check CCA's.

That being said I did replace 1 battery, but the problem is still there.

So pissed truck is only 2-1/2 yrs old.

Last truck was 6 not one problem.

I had a bad battery in my Hellcat that was 2 months old, so age is arbitrary when discussing batteries.
As @watersupply189 said, you should have a warranty on the battery so you should be able to get it swapped out easily.

Side note, I live in Arizona...batteries here last half the stated life due to climate (AutoZone's warranty program is beast for this)....I see you're in MA...you have an extreme climate as well so if you got 2.5 years out of a 5 year battery, you're tracking right on target for conditions.

Checked other battery. It was fine.

Came in this morning to work started w/ me in it. Went out to grab something it was running.

I've wanted this truck for 15 yrs now this not happy.

So either my other battery is **** or my ECM is fucked.

Are you the original buyer of the truck?

If not maybe the previous owner is messing with the Uconnect app and remotely starting and locking the doors?

I know when I traded my 2015 in, the app was still active on that truck and I was able to see location and everything even with my 2018 sync'd to my account.

Had to call Chrysler and let them know I was no longer the owner and they removed it.

Ok let's do this.
Get your truck on a battery charger/battery tender
Revert your truck entirely back to stock tuning (don't worry about hard parts, you'll get some CELs but thats ok)
Once the stock tune is loaded, disconnect the MM3
Disconnect both batteries and wait 15min, or press the brake pedal 5-10 times, or touch your positive & negative terminals together
Remove the SD card from your MM3 & reinstall your firmware & tunes directly to the SD card...if you don't have a SD card adapter for your computer, you'll need to get one.
Reconnect both batteries & functions test the truck.
Reinstall your MM3 & perform the firmware update again.
Reflash tunes to truck while connected to battery charger/tender.

Report back.

Sorry for the delay guys.

UPDATE on what it was.

It was the F!@#$%#ing key fob.

So my son had dropped it and on the inside of the fob where the buttons are are little concaved things.

While one came loose/unglued and wedged its self inside and keep making contacted w/the button.

My wife fixed it and figured it out so there it is.

Hope someone learns from this to check the fob .
