Hello guys I have a 2014 Jeep Wrangler Unlimited Sport, some time ago it started to give me a “HOT OIL” message Where the mileage is displayed when I try to start it it does not starts displays only displays the message and beeps and I hear some click in the dash, near the A/C module, after trying to start it a couple times it does starts normally, i’ve never had the message displayed when running or something like that and there is no pattern on when it displays this message, it can be in the morning when the car is cold or it can be just after turning it off at the gas station and fueling the tank and it does not do it always sometimes there is weeks that it does not displays the message and sometimes ti does it every day but at the end it always turns on, i have taken in to a couple of dealerships and “specialized jeep mechanics” but they don’t find anything or just “can’t replicate the issue” I uploaded a video on youtube for you guys as reference, to see if maybe some of you have experienced this problem before or maybe know what is this exactly about, here is the link to the video
any help would be very much apreciated, this is already driving me crazy, if I can’t get this fixed im thinking of getting rid of the jeep. Thanks again you all!

If it is a rubicon check the front sway bar module. Unplug the main connector on the sway bar motor and see if its full of water. blow all the water out and leave it unplugged and see if that fixes your issue.

So I don't believe they have a Rubicon.

It's really hard to help you unless you can tell us what you've tried and searched for. Stating you need help without going into details doesn't help anyone really. This is why @j3ff3ry_j33p requested more information from you.

You state the dealer has replaced the ECM, but you don't cover if this was in relation to your issue or something unrelated. So if the dealer replaced a part for this and it didn't solve your issue, then I would say that the dealer is on the hook for looking into this further as long as it wasn't somehting you asked them to do. If it was for something unrelated and your issue occurred after they replaced the ECM, then they're still on the hook for repairing what they caused. And if going to the dealer was unrelated to your issue and replacement of the ECM was for something else, then letting us know that can help you further.

Details of what you searched for, details of the ECM replacement since you mentioned it, and what you've tried leads to better help. So as you can see, you need to start providing more information.

Good luck... :wink2:

Anyone found a fix for this "hot oil" on cold start issue. I live in SWFL, so not that cold on the start. I have a 2018 JK and it's been happening for about a year now. I went to the dealer and after 6 weeks, they said it was the Electronic Transmission Control Module. Replaced it and no issues for about 6 months. Started happening again and eventually wouldn't start in a parking lot. Had it towed to a shop. They replaced the Starter Relay. That was maybe a month ago and this morning its back to hot oil and no start. This is a total mall crawler that gets driven less than 30 miles a week most weeks. Please help!

Do a couple easy things: disconnect the negative battery cable and drain the capacitors.
Trickle charge your battery until it is 100% charged.
Get an OB2 code reader with a mil reset function. No need for a Procal if you only ever want to read and delete codes. Otherwise I use the Torque App and a $25 Bluetooth dongle.
A low charged JK battery does weird things, if the issue comes back, you can clear the code

I’ve been having this issue for a year with out my jeep starting a single time in that time period. There doesn’t seem to be a lot of information on this. The dealership told me to replace the wiring harness behind the dash but jeep no longer her makes that part. As soon as I turn the key on it gives the hot oil warning and doesn’t crank. I also noticed my trans temp on the dash is displaying -56 F. I’m going to try a trans temp sensor but any suggestions would be greatly appreciated
