I was driving home today in electric mode through side streets followed by a bit of stop and go on the freeway in electric mode. Temperature was 80 degrees Fahrenheit and my Jeep switched from electric mode to hybrid mode and a message popped up on my dash saying electric mode currently unavailable and switched to hybrid. Is this working as normal or something I should be concerned about? It appeared to be temperature related the electric motor was still operating in hybrid but I was unable to switch back to electric only mode

I got this same message driving the other day, it was pretty warm out and I was driving with Max Regen on in electric mode and suddenly the gas engine fired up and it said electric unavailable. I didn’t notice any temp warnings or anything out of the ordinary. After a few minutes of driving the next time I let off the gas to coast it shut down and went back to electric mode. It was about 15 degrees hotter today and it didn’t do it. Strange.

I did notice the power on electric mode was starting not as responsive as normal before the “electric mode currently unavailable” message popped up. Then the gas engine turned on and flipped to hybrid mode… any thoughts from the group? It was a bit hotter outside than previous days

Hey, all. Although I cannot speculate on the normalcy of what you all have described, if you choose to visit the dealer for information, we are happy to help. Send us a private message with more details to get started.

my thought : shift from electric to hybrid mode to cycle through fuel refresh. the bmw i3 rex does it too from time to time....so i think it is normal.

from the text book wrangler 4xe:

GETTING TO KNOW YOUR INSTRUMENT PANEL 37
FUEL AND OIL REFRESH MODE
Since it is possible to operate this vehicle for extended periods of time without running the gas engine, the fuel within the vehicle’s fuel tank can become stale or the engine oil’s lubricating properties can be reduced. To prevent engine and/or fuel system damage due to stale fuel, as well as maintaining internal engine lubrication, this vehicle is equipped with a Fuel and Oil Refresh Mode.The vehicle will automatically enter into the Fuel and Oil Refresh Mode to minimize potential for stale fuel, and to ensure lubrication of internal engine components. When operating in this mode, the gas engine will run to provide vehicle propulsion (electric only operation is inhibited). A message will be displayed in the instrument cluster whenever Fuel and Oil Refresh Mode is active.The vehicle will automatically exit the Fuel and Oil Refresh Mode when conditions have been satisfied. If the vehicle enters Fuel and Oil Refresh Mode, due to fuel which has been in the fuel tank for a long period of time (becoming stale fuel), the engine will run whenever the vehicle is operational (no electric only operation) until the low fuel level warning is activated. It is also possible to exit the Fuel and Oil Refresh Mode sooner by adding a minimum of four gallons of new fuel to the vehicle’s fuel tank.

NOTE:If the vehicle enters Fuel and Oil Refresh Mode to maintain engine lubrication, adding fuel will not exit the mode sooner.If the vehicle enters Fuel and Oil Refresh Mode to maintain engine lubrication properties, the engine may run for a period of up to 20 minutes when fully warm whenever the vehicle is operational (no electric only operation). If the vehicle is shut down before conditions to exit the refresh mode have been satisfied, the engine may run for additional time on subsequent trips.

NOTE:Frequent short trips at low ambient temperature conditions are more likely to trigger the lubrication based mode.

Am I to understand its only the full ellectric mode thats disabled in refresh mode? We still get the full combined hp and torque from the whole system in hybrid mode while its “refreshing” right?

Absolut Right !

just make sure you have some gasline in your tank 😉

I’m starting to think my issue is not fuel refresh mode. To clarify does the dash actually say fuel refresh mode when triggered?
My issue is specifically when driving at highway speeds up a slight grade/hill in full electric. I begin to lose throttle and speed but the ICE doesn’t turn on. Even if I pedal down the car just loses speed then I get a signal “electric mode unavailable” it flips to hybrid and the ICE kicks on

appears to be a limitation in the “electric only mode”

Has anyone fully resolved this issue (Electric Mode Unavailable. Cabin cooling...) ? Seems to be quite a few posts on this but no formal resolutions. If you did get it fixed can you share how? Thanks!

The issue with your 4xe is not the fuel or oil refresh mode that others have suggested, as that has a specific message stating such.
The issue is the batteries and the P2 motor are overheating because the cooling system can keep the system cool enough.
My P2 motor has reached 369F and my batteries have gotten up to 122F driving it 5.5 miles to the grocery store and the ICE constantly kicks in with that same message.
The Stellantis field advisor that test drove it says I should only drive it around town at slow speeds like an old grandpa and it should be just fine.
The window sticker said 21 miles at highway speeds. 🤷‍♂️

Purchased my 4xe last weekend and tried driving to work in electric mode yesterday. Was on the highway going 75 and six miles into the drive I lost all power. Gas pedal did nothing, no warnings on the dash I just couldn't accelerate. I switched into hybrid mode and it went back to normal but I got a message that electric mode was unavailable.

my car just started doing this today, it hasn’t been warm out at all (probably 40’s this morning). My car says “Hybrid”, but I know very well from the horsepower/responsiveness and sound/feel that my car is actually in all-motor mode. It probably says Hybrid because it uses the motor as well. I’m guessing there’s an aussie with the battery or it’s connections.

I’ll be contacting the dealership soon. 😔

Just an FYI for all posters to this forum concerning the issue of Electric Mode being unavailable. I was able to just add some more fuel to my tank (91 not 87 or 89). Once the vehicle was restarted the "Fuel and Oil Refresh Mode In Progress Engine Running" message disappeared and all modes were accessible again. 😎

Dang, must be nice! I filled up my tank and ran it 25-30 minutes at 60-70 mph. Still can’t access electric mode. 🤷🏻‍♂️

I just started joined! Sweet. Check engine just came on… not sweet. I’m also getting electric mode unavailable. Saying b/c heating cooling system on. But happens even when both are off. Have 70 miles on it. Will report back if anything changes.

The Jeep only has 134 HP in all electric mode. Highway speeds will be pushing the battery system quite hard in pure electric mode considering the weight of the vehicle.

I mean it should handle things more smoothly, but it’s not that powerful on only electric.

We have the same issue - brand new Jeep Rubicon 4XE and "electric mode temporarily unavailable". That was despite 100 miles on gas on the interstate, in normal 40-50 degree weather. And there was no message about any "refresh mode" anywhere.
It will go back in the shop and if they cannot fix it, it will go back under the lemon law.

This is nearly identical to my situation. I left it at the dealer for a couple days and they drove it for 40 miles. They "didn't find anything". Now it's fine. I don't know....
