Unfortunately, I have joined this club. 6 weeks in and the CEL came on today at just over 1400 miles. Tried to make service appointment but so far have not heard back from the dealer. Checked the gas cap but no change. I had already read about the loose fuses issues weeks ago and checked them then (indeed several were not seated properly). Tried and OBD2 scan and got code P04EE so far I cannot find any info on that particular code. Hopefully the dealer will call back tomorrow so I can get it looked at. Everything seems to be working just fine and there were no differences in how I charged it prior to the CEL coming in so I have no idea what’s up with it. As others have said, even with everything apparently working okay, it’s frustrating to have to deal with a CEL on an expensive brand new vehicle.
2021 Jeep Wrangler JL Safari 4xe. Bought last Saturday. After dealer cleaned for delivery, back up camera quit working. Yesterday, one week and 54 miles later, CEL comes on. Take to dealer, they have no idea. Code reads two things, a minor and a major leak. For $62k, I expected more. Hope Jeep figures this out quickly.
2700 miles, CEL this morning. Using level 1 charger from dealer, unplugged and started up Jeep. At startup, appeared to be much louder then usual so i though maybe the garage echo was amplifying it. Pulled out of garage, very loud for 30 second to a minute. Attempted to place into electric mode to "quiet" it down, got the message below. Tried it again a few minutes after while driving, still now allowing me to place in esave or electric. No messages appearing on dash, CEL is present. Contacted dealer, sounds like it will be going in tomorrow and i will be provided a loaner. I knew i should have went diesel... :(

I'd be glad to, but I don't know how to do that. Can you enlighten me on that process.

I am 2 weeks in with my new 4xe Sahara and the check engine light appeared today. 🤦🏼‍♂️
The touch screen has blipped a few times and restarted itself too, mainly when I have my phone connected and am on a call. Oh, and I also have the issue that many have with the backup camera lines disappearing. I am loving the new Jeep (only regret is not getting the Rubi version) but definitely a pain having to bring back to the dealership so soon for repair And leave it there.

Getting codes in my new (~400 mi) 4xe. They are saying bad wheel speed sensors. Anyone had this yet?

Have not yet been into my dealership to get it checked out, figured I’d ask here first!

Update: Dealership figured it out. Said it was a stored code showing a small air leak. I had the gas cap tether apparently caught up blocking the seal. Who knew. All good now.

Spoke with dealership today. Mentioned they spoke with a "specialist" that contacted them. Also mentioned the issue being tied to a PIM (Power Inverter Module). Guess we will see how long it takes to get the part and fixed. Thank you Kate for moving this along, much appreciated.

2021 Sahara 4XE (on order)
Add me to the list of check engine lights. Everything has been great until this morning when I got to Work and plugged in the Jeep level 1 evse. The Jeep would start charging and then 15 seconds later it would fault out. I unplugged it and tried again with the same results. I waited about 20 minutes then tried one more time, this time everything worked fine and it started charging. At the end of my work day I went out, unplugged the cord and was greeted with the check engine light. I drove to the dealership and they ran the codes. It came back with P0D27 Batter charger 1 input voltage too low. They reset the codes and we will see if it happens again. I have used this outlet at work for the past 2.5 years to charge my Chevy Volt so I’m pretty sure the outlet is fine. I used the Jeep level 1 evse yesterday on this same outlet with no problems. I have charged overnight at home with my level 2 evse with no problems. I picked up the Jeep less than a week ago 1500 miles away and drove it home with zero issues. Hoping for no further problems 🤞

2020 Sahara JLU, 2021 Rubicon 4xe on order
Mine has been in service since the beginning of the month (2nd time) for a P0C74 code (motor electronics coolant pump "B" control performance). Much longer the dealership will have my new jl longer than me. 1700 miles. Sold my 2020 Sahara with no issues for the Rubi 4xe. I was loving it till this started. I hope it's really fixed whenever I get it back this time.

I've seen similar posts. For whatever reason the 4xes just seems really sensitive to some chargers. I don't know why they choose to throw a CEL over it as it causes unnecessary worry to owners.

First year model. Gonna suffer a few growing pains.
I would love to buy a 4XE in about 3 years after Jeep has worked out all the problems.
And hopefully by then it will run on electric for the first 100 miles.👍

I don't think that range will be there in 3 years unless it's a BEV. There is crazy battery tech on the horizon.

I just can't see a fully electric wrangler having good range anytime soon. Other trucks are now doing it but they aren't held to maintaining the offroad capabilities.
