Hi there.... have a somewhat similar situation. Have had my Jeep for about two weeks. Love it...except for...I can start in hybrid and electric and go until the motor kicks on - either through acceleration or battery depletion, and then the motor never turns off - even when in hybrid mode, and at a stop sign. Further, it will not let me go into electric mode after the motor has kicked on. I'm also getting the fuel and oil refresh, though I "thought" it would fix itself after I fueled up yesterday. Same results. I can get it to go back to electric mode if I turn it off and back on, but that's a pain, and not why I purchased the 4XE....Hello!
Temps have fallen in Idaho as winter is approaching. I park my 4xe in the driveway overnight so it is exposed to whatever the temperature is outside. Last week the temperature was down in the upper 20's. The jeep was fully charged when I remote started it. The gas engine started up right away and stayed on for what seemed like 15 plus minutes as the windows slowly defrosted. I figured that it was using a lot of power to preheat the cabin and defrost the glass so it needed a boost from the gas engine. I'm not happy with this function. I bought this vehicle to feel a bit better about my impact on the environment. Seeing it spill exhaust in the cold morning air puts an exclamation on my dissatisfaction with this process.
I decided to leave the 4xe plugged in overnight so the next morning when I remote started it there should be no issues with battery load as it is still hooked up to our home. Just for note, we use a level 2 charger for the Jeep. However, the same thing happened as the gas engine fired straight up. So I want to know if there is a solution for this or do I have to deal with my vehicle spewing exhaust every winter morning as my car defrosts. This would be a total bummer.
I reached out to Jeep customer care but they had no idea what I was talking about and had no place to send me besides our local dealership who I have found to know little about the 4xe when I have questions.
Hopefully, there is a jeep 4xe program engineer out there that might weigh in on the question.
My 4xe has a little over 2k miles, I have a little over 1k miles on this tank of fuel that was filled on Oct 2nd, 110 miles hybrid the rest electric. I plug into my Level 2 Grizzl-e classic after work and usually don't unplug till I'm leaving for work the following morning, some round town driving on weekends then plugging in. I don't charge at work, or any other places. Oil life is showing 75 percent I think. I took delivery September 17th. In my daily commute I use electric mode. Any hwy driving or high speed driving I run in hybrid. HTH@Sjbiss Thanks for pointing us towards that very informative article. After reading these were my takeaways. I do have a fairly fresh tank of gas and I recently changed the oil so there should not be any issues with fuel or oil refresh. With the typical distances, I drive per week, I usually run into the ICE starting at least once a week as well.
@Grimmjpr mentioned he is dealing with the same mid-20s outside temps then remote starting and he's not having the vehicle kick into ICE mode. I'm curious what the situation is for him.
It's very curious and again I can't understand why the engine needs to fire up if the jeep is plugged into a level 2 charger during warm-up.
