The warning lights came on after two days of having it and 120 miles, once the battery went to zero the engine did not switch over to gas so I had to pull off the road. The car immediately started back up and worked normally, the lights turned off and has functioned normally since. I took it to the dealer, They kept it for five days and talked to the engineers at jeep Chrysler and could not find anything wrong. I had purchased a lift prior to all of this so I just had them go ahead with it. As one member of the forms said if you wait to have a jeep without problems you will never own a jeep. We will see
Every single relay in the fuse box on mine was loose. I wonder if that could be your issue.

@aspst10 Do you know which part number of Mopar lift was installed?
It should be listed on your receipt.
So it turned out they actually used a TeraFlex 3.5 inch lift because the Mopar one actually didn’t fit.

Well it’s working normally now so who knows. After the lift and bigger tires interestingly easy battery life went down to about 15 miles on a full charge

This is interesting. So did you order the Mopar and then when it didn't fit they switched to TeraFlex? And why didn't the Mopar work? Whats so different from the JLUR and 4xe?

Actually, since it looks like you're the first person with a 4xe lift, you post in here so we can talk about the lift specifically

Just found out tonight that the Level 1 charger will NOT work unless it's plugged into a GFCI outlet. Typically not a problem unless you decide to plug in at the old barn built in the 1950s on the farm.

Depending on the rating of that extension cord, they might have burned down that barn.

Kind of like a trailer hitch - just because you can hook it up to a 15,000 pound trailer because you have a 2” ball on your hitch does not mean you should. 😂

Folks - please don’t use any extension cord with a high current draw device (aka a level 1 charger) unless you know the cord is rated to carry that amount of current over the length of the cord.

Yep just to see if it would work. Circuit had a ground but no GFI. Charger would not work. We're headed out West this Summer and stay in some rustic areas so I'm going to take a little plug-in GFI module along just in case.

I doubt it's the GFCI that made the difference there. All J1772 EVSEs are required to have internal GFCI anyway (so an external one would be redundant), and there wouldn't be a way for the charger to determine whether the outlet it's connected to has GFCI without tripping it. Most likely that old outlet is improperly or weakly grounded or has some other wiring issue.

Likely a grounding issue. My house was built in the 50's and the outlets on the inside are not grounded. I tried one, it didn't work. I tried an outlet on the add-on laundry room at the back of the carport and it worked fine (it's grounded).
