4xe dead battery

[Bigcountry]

Have a 2022 Rubicon 4xe. Flat towing behind Motorhome. Added all the flat tow hardware from etrailer. Flat towed for 2 days without starting Jeep. Tried to start and battery dead. AAA came out and jumped it. Any thoughts?

Uhh, bad 12v OEM battery?

Only 1300 miles on the Jeep. I guess it’s possible, but holy cow.

Mine did that too. The braking system (Air Force one) if you have it, uses up juice from the Jeep starting battery. Mine went into limp mode after a jump. Cycled the power on and off a few times while each opening and closing the door. Tire light was on, check engine light was on and traction control light was on. Eventually they all went off and no more of an issue.
You will need to run a power wire from the MH to the Jeep to keep battery topped off or at the end of each driving session of MH, put a charger on the jeep. That's what we did. I will be trading in the 4xe for a gas rubicon with the XR package. It was not available when I bought the 4xe. I do have to say, I love the 4xe but not all the computers associated with it. Now there's a recall on the HV battery. I charge it outside of my garage by 10 feet.

Went out this morning and mine was totally dead. It had been plugged in all night too. Cycled plug in and still nothing. No relays clicking, no blinking light by charging port.

Coincidence that I received an email from my local dealer this morning wanting my Jeep back to sell?
