I have seen this message flash on my dash a few times as well, (2022 JLUR, 2.0L). It is usually while coasting and goes away when the gas is pressed. It has happened about 3-4 times (less than 1000 miles on Jeep). The warning message always goes away quickly. I have only used Shell Premium gas. I suspect it's an electrical gremlin that is unlikely to be significant, (I hope); the Jeep runs perfectly and I'm getting 18 MPG.

Does the engine or exhaust vibrate while coasting, especially during the transition?

I'm wondering if a knock sensor is getting a false positive...

Because nobody knows that. If it were software, It'd probably be OTAd by now.

Your guess isn't any more valid than anyone else's.


(And gas does also cause this issue)

Software updates take time. The simplest fix obviously would be to remove that warning altogether, but it exists for a reason.

It’s not a gas problem. It’s absurd to say that a huge number of brand new vehicles of a specific make, model, and year are all suffering from their local gas stations unclean fuel.

We didn't know how many there were the entire time.

Also, it's not absurd. It's not like gas is like beer, having hundreds of local breweries.

First place to check is to reasonably rule out gas as a problem.

A huge number of brand new vehicles of a specific make, model, year AND engine. This is only one engine the 2L. junk

Mine is doing this. JLUR picked up in TN two weeks ago. Poor gas mileage on the way home. Attributed this to heading into a headwind. Going uphill into NM, and other gremlins. Mostly figured it was from getting on and off the gas, some backroads etc.
My latest tank from Costco, 91 oct, I am getting 18.3 and drive 20 of 22 miles on the freeway during rush hour. That's OK but I think it should be a little higher.
Today when I got the message I was decelerating and the message disappeared when I got on the gas. My ESS was off. Just went outside and checked my gas cap.
This could still be a lot of things but I would guess software related. The sensors are doing their thing. When you get off the gas the TPS closes the throttles and you decelerate. Fuel maps are very low at idle / low RPM for EPA. When you get on the gas, fuel pressure may be on the low side and the second or two it takes to build pressure feels like a lifetime.

Sure, then you have pages 2-17.

Wait, nevermind, I didn't start this one. The one I started on another forum only has 3 pages of friends. 😟 I suck, no friends.
Don't worry, pal. We're like BFFs. Our Jeeps are almost identical twins. 🤣

I got the message today but it's only happened once before and that was 4,000 miles ago. What is interesting is that it happened at the same location where it first displayed. Exiting the highway I'm coasting down the exit ramp making a left turn and braking to burning off speed. I hit the throttle to see if the pedal was dead but it responded. Coincidentally I did fill up a few miles before because the gas pump light turned on and it took 14.5 gallons of Phillips premium.
