I just got my 4xe....this is my second day and the Wrangler won't start! I had it plugged in with the included Level 1 charging cable, it charged overnight. The charger has a green light (there's power), but when I plug into the Wrangler, there's no light. The battery is completely dead - can't unlock/lock. Anyone else experiencing battery issues?

Welcome to the forum.

Unfortunately yes. Dead batteries and JL Wranglers go together like peanut butter and jelly.

I don’t know 4xe enough to be of help. On other JLs, the problem is the charging system not working properly.

Time to call Roadside Assistance and have it towed to the dealer.

In hybrid cars, the whole electric system is often integrated in such a way, that it the hybrid system fails, car will not drive. So the problem is not necessarily in the "normal" 12 volt battery side.

However, if the car is completely dead, the 12 volt battery is dead, or disconnected. Can be a shitty job to figure out what killed it.

The cable being plugged in might prevent start, but it will not cause blackout.

First thing to check is what @Erik Latranyi pointed out. make sure the charging cable is disconnected. Next is to make sure the connections to the 12v battery are secure. If it still won't start and doors still won't unlock electronically then I would check the fuse for the IDCM (F09). The IDCM is responsible for a lot of things in the hybrid system and two of those things are converting power to charge the main battery, and charging the 12v battery. I Would think a code would be thrown if this component was malfunctioning but worth taking a look at if the simpler things don't do the job. After that its def a dealer call. Two days old so literally everything is under warranty.

My 3 month old 4X3 with 3K miles on it started with the engine light on and not starting or if it would start would stay on both gas and electric and i i could not switch to electric or gas only. After 3 weeks in the shop i am told this week that it’s needs a power inverter and it will be the end of October before the part can be “built” and shipped.
