Random Jeep chatter

So their “40 amp” extension cord is made with 8 gauge wiring. If you were installing wiring to support a 40 amp evse, youd use 6 gauge minimum as youd be sizing for a 50 amp circuit aince its a 40 amp continuous load. Especially after you factor in the extra voltage drop from the longer run, etc.

If youre going to use one of their cables, bare minimum up rate from their suggestions (i.e. at least use the 40 amp version for the 32 amp peak for the 4xe) and do t use the cable on anything that charges at a higher rate (or better yet, limit your evse to no more than 32 amp.

this is the questions i asked if the cable could be customized.

I actually did just find one that is UL certified (weird they call it approved and not certified per se) and looks like they do custom lengths.

Not weird at all. Theyre buying cable raw stock that itself meets ul standards for the cable and then creating an assembly out of it. The assembly itself is not ul certified/tested/etc.

A lot of the chinese companies do this with their evses that they claim “ul compliance” or something similar on… they use individual components that are ul certified and then pass that off as the actual unit is ul certified.

Ah, I see. Good information and thanks for the input. I will keep looking.

don’t feel bad. i smacked into the exact same morass of word salad designations a few months ago. its a bit of a minefield out there.

Day 1 - Mine was delivered early yesterday and I put a 100 miles on it. Took backroads to the beach and then the highway back. The SOT was the right move.

Day 2 - Now, only if I could get the Jeep to move. It’s blocking the other car in my driveway and is dead. The key fob didn’t work and when I got into the cabin I saw it has no juice. Started a roadside ticket through Mopar at 6:40 AM, forty five minutes have passed and the only three updates I’ve gotten are apologies for the delay with no human to speak too.

I got this to Jeep to keep. If issues with this service persist I’ll be joining the flip club.

Have seen this once or twice where the battery cables for the 12v battery were loose. Also worth checking all the fuses are fully seated.

Battery is snug.

Fuses needed a nice push to get set.

Still dead and almost two hours in with no response from Mopar roadside.

Any chance you left something on overnight and drained the battery? This screams dead/disconnected 12v battery.

100% chance this happened. Two little kiddos in the backseat playing with the new toy and turning things on and off, while I am doing the same up front.

Roadside said they tried to find someone and couldn’t, because it’s a Sunday. Then thanked me for my patience as they escalated the ticket. I asked to be left on hold as they did so and got “disconnected”. Called back a minute later and someone is already assigned. If support isn’t available 10 minutes from Downtown Los Angeles I am concerned to see what it looks like elsewhere.

Sad that Mopar is setup to open a ticket yourself and then proceed to berate the call center employees to get it escalated.

Roadside came three hours later and jumped the battery. Good news, I can see no one in my family left anything on to drain the battery. Bad news, its still dead and I saw an alert for the plug in battery. The electric battery charging faults appear to have drained the 12v. The charging cable has yellow and red alerts. Roadside support tech is gone and my jumped battery is now dead again and a window was left down.

Anyone else deal with this that found a solution?

Can you jump it w/ another vehicle or neighbors? Then drive it around for 30 minutes or so?

Also check YouTube & the 4xe forums for solutions that previous people have found.

I wouldnt jump to that conclusion. A low 12v battery signal can and will set off all kinds of error messages that go away when a fully charged 12v battery is used.

If you can, take the 12v battery to an autoparts store and have them charge it.

Brought the battery to AutoZone and it’s a goner. Out of the possible scenarios that was the best result. Now I wait for the local dealerships service department to open tomorrow in hope of a easy swap.

All these transport delays are not good for these 12v batteries. My 4xe was built on 6/22 but currently stuck in the logistics hell. It has been sitting in the Utah rail distribution center since 7/5 with an new est delivery date of 8/15 now. I am going to ask the dealer to test the battery before delivery.

Annoying and not something you should have to deal with on a one day old vehicle, but fortunately its super trivial.

Jeep aeems to use the crappiest 12v batteries they can find. Its always amazing how many you hear about dying very early in their life.

Mine just randomly turned off but didn’t try any adjustments to cables. It turned on 20 minutes later…it’s a mystery at this point

Speaking of JL forum, I don’t have an account there and I’d rather not register for yet another forum so I’m going to ask my fellow hackrs. Been driving this thing for about a month now and I’m experiencing a whine during electric only mode. Definitely not the pedestrian warning system. More like a ground loop whine. It gets higher pitched as my speed increases.

Has anyone else noticed this? Normal? It’s not a deal breaker but it is annoying on a $63k vehicle. Trying to avoid taking it to dealer if at all possible.

Is it the electric motor?

Are we not supposed to drive the Rubicon above 70 when there is high wind?
I hit 50 miles on the highway today with soft-top closed. The noise was a LOT when I went over 70. Is it supposed to be this loud? Do people just drive it slow on the highway?
