Was there any leaking coolant underneath? If so, likely the screws for the coolant inlet to the water pump.I'm not sure if I'm in this club yet, but earlier today I was driving on the highway. Could hear the fan coming on which I thought was abnormal but disregarded it as it was hot out.
I stopped for a late lunch, when I started driving again almost immediately the temperature kept going up to the point of hitting the red and backing off. It kept going back and forth so stopped at a gas station, opened the hood. After a couple minutes I left again thinking it was still related to outside.
The oscillating temperatures started again so I pulled over to the side of the road in a neighborhood. Had the hood open and talked to a few people about what to do. Saw a jeep dealership was about 6 minutes away so decided to try to drive there. This time the red came on and stayed. I sat in the parking lot a while and then went to talk to the service. Of course by the time I moved it into the service bay it wasn't on red anymore. I never went into limp mode. I didn't check the engine coolant as I didn't know to do that at the time.
They're going to look at it in the next day or two. They had no loaners, so I had a really expensive hour Uber just halfway home to a friend's. I called jeep service and they opened a case for me and to have rental car reimbursement starting tomorrow.
I was on the way to off road too '21 Willys, just hit the 8000 mile mark. No previous issues on the highway (even yesterday).
So so sorry to hear that!What are the odds? I have been reading this thread this week and was getting ready to perform the tsb myself this weekend.
Now i am on the side of the road waiting for a tow. Was driving on the freeway and the temp shot up, got a warning light and it went into limp mode. Was able to get off the next exit. Got up to about 270deg and coasted about a 1/2 mile.
Eta. 2022 built late December with 7000 miles.
Unfortunately I can't answer either way. I was kinda frazzled and didn't think to check for leaks at either spot. Someone told me how to check the coolant level but said to be careful and I was more focused on getting off the road and to the dealership.Was there any leaking coolant underneath?

Clear is likely from AC. By the time you reached the dealer, chances are most if not all the coolant was likely gone.Unfortunately I can't answer either way.

There was a pretty small, seemingly clear puddle under my car in the service bay, maybe at the halfway point. It could've been there before though. AC? Though I wasn't running it.
Update on mine- They replaced the water pump, refilled, pulled vacuum and no leaks.. Temp is a little more touchy as it will fluctuate between 180-205 now instead of just hitting 195 and sitting there. 200 miles since fix and no drop in coolant level for me.Just had this happen to my 21 JLU Sport with 11.4k miles. Massive Sweet smell when I started it up and temps hit 280 with a message on the dash. Pulled over and had a nice big puddle of coolant. Was 130 miles away from home and So far not impressed with the response from the service department where its at. Stated can't even look at it until next week and then only gave a rental car for a day until they determine cause(warranty or not).
Quick update on my case: service dept from the dealership just called me mid-diagnosis to ask if I had added any coolant to the system. Looks like I don't have a leak, BUT I think they checked for this TSB and a lot of my bolts were loose. He said that one potential theory (which I can't comment on if it happened or not) is that when the engine gets hot enough, air was sucked into the coolant system since everything was loose, and that air pocket working its way through caused the coolant itself to stop circulating as well and thus overheating.
In any case, they said they'll have another update tomorrow, and perhaps be done.
I sent my interruption cost to the case worker Friday. This included scanned copies of the hotel, and Chapman receipts. Also included was scanned copies of individual dated charges with location, merchant and charge amount from one credit card and itemized charges with location and merchant information from a different credit card. The second credit card dose not give individual charge information. But the line items do have date, reference numbers, description (merchant and location) and charge amount.
This is the response I just got.
" I have received the document that you sent in. However yo submit for possible reimbursement we would need any receipts that you would like reviewed. Please reply to this email with any and all documents you want reviewed. "
Looks like they setting up for denial of trip interruption reimbursements.
