I have asked about this as well and from what I have seen online and observed it appears to possibly be protection built into the system. In my case, it happens when I am low on battery (5-8%) and have been driving at 65+mph. It happens pretty consistently on my commute which is 22/24 miles each way but the middle of the commute is all interstate so I am regularly doing 65 to 75 mph and near the end when low on battery it kicks on the gas engine - then when I exit and going slower speeds it will go back to electric. Not sure I have answered anything for you but sharing an observation I think there is just not enough power left OR the batteries/system has gotten hot enough that it kicks you off the battery-only mode.

I have observed this when driving on highway speeds 70+ MPH and going up hills. For me it appears to be tied to hotter temperatures outside and reduced battery performance.
Electric mode is somewhat of a joke to me. This is hardly a fully electric vehicle if I can’t even drive home on the freeway without it flipping the ICE on

For me I get the message any time i'm cruising fast on electric mode at like 75 or 80mph. It can kick on as early as 22%. I think the batteries get hot and the jeep has to cool the batteries and it says stop. I'm in SAT and it gets to 100 degrees F (40 C). I have also noticed when I throw it in the garage to charge, it may not charge right away and i will come in an hour later and it did start to change and the fans are running full blast.

I just got my Jeep yesterday and I believe the dealer filled up the tank for me so dont think its old. But today when i was driving on full electric, it kicked onto hybrid mode and would not let me change back to full electric even though I had about 71% charge left. Same electric mode currently not available….I have been having nothing but small issues like this which worries me. (Check engine light on, fan blasting every 2 hrs or so in the garage while charging, and now not being able to drive full electric mode which is why I bought this car) Is this all normal? Please help…

You might need to have the cooling fluid bled in your battery. If the battery gets hot, it becomes temporary unavailable. Do you hear "boiling" or "water" noise under the back seats (where the battery is located)? Had this issue. Brought it back to the dealer and the remove the air in the cooling system. Fixed the "temporary unavailable" issue.

Also, one of the recall has to do with the power returned into the battery while driving. There is something wrong with the power storage managed by the chip..

I do not hear any boiling noises and it worked perfectly fine today so hoping its not something that needs to be replaced already. I just picked up the Jeep. Thank you for your feedback though so I can keep an eye on it.
