Posted a couple other places, but want to make sure I cover the bases on this issue to share that I think my issue was solved. I took my '18 JLUR in today for the TSB noted in other threads. See image below. Issues were: Loud fan. Surging idle which causes lunging or dented garage doors when...

Follow-up: I took my '18 JLUR in today for the TSB noted in this thread. Loud fan. Surging idle. I literally saved the image on my phone and showed the TSB number to the dealer. See below. They were great about it. They took the car, gave me a loaner (i did have to request it when i made the...

Back to the topic: I posted my idle/engine surge issue on another thread, but I think it applies here as well: I’m here in Portland and we just had a really hot week. Each day required a/c and as I got halfway home I started noticing the surge at stop lights. Just before I stopped and the ESS...

I’m here in Portland and we just had a really hot week. Each day required a/c and as I halfway home I started surging at stop lights. The worst was when I got home. I park close to my garage door. If I wasn’t mashing the brakes it would have surged forward and pushed in the door. You can also...

I never got the charging message. The aux battery was bad and they just replaced it. I dropped off in the AM and by the time I came back to pick up all was working.

True. That's why i just took it to the dealer. The battery is covered under warranty so no cost to me. There was also a head unit update that fixed the buggy apple carplay navigation issues.

here's how:

Follow-up to my prior post. Two things: First I mentioned an issue with start/stop unavailable message always being there - problem solved here. Second, the dealer didn't see any specific issues with the radio that would always cause it to start from my house, but updated the radio anyway with...

https://www.jlwranglerforums.com/forum/threads/service-stop-start-system-warning-light.5370/ Dealer visit solved it for me.

Another follow-up - problem solved. The reason ESS wasn't working was due to a faulty secondary battery. I was told that it's happening a lot, and I was lucky to come in when i did because I was able to get the last battery they had in stock. The replacement was covered under warranty, so no...

Same issue here. Started this past weekend during a road trip to Seattle (we live in Portland). Nav always starts us from our home address and fumbles around for the first 10 minutes then corrects itself. Happened to my phone, then the same with my wife’s phone which had never been connected in...

Follow-up ... I went in for service on Monday, after making an appointment last week. The appointment was for 8:45a. I asked at the time whether there was anything else I should know about the car which may justify the 82 miles on the odometer or the fact that the battery cables looked like...

Poked around in the internet to read up on ways ESS could have been disabled. Jeep Informant showed how it was connected to the main battery and the sensor (tall button) under the hood. Just for kicks I looked for the same areas under my hood and found the connection point at the battery...

Same problem on my new JLUR. Along with the auto stop/start service unavailable message being there since delivery. If I didn’t love this rig so much already...

Happening here, too. Just got my new Black JLUR and since I drove it off the lot, I've been getting the "service unavailable" message for ESS. Hasn't worked once. Dealer told me as we were getting gas for the car that it was "finicky." Probably a bit more to it than that.
