Update: Just got back from dealership. They replaced the Electric Heater and everything back to normal! Thanks to this forum and a youtuber for figuring this out. The dealership was still trying to say "normal operation" but armed with all the real life info from other owners and the star case number it went pretty smooth for the second service visit.
Original post: Ok, so I did read the other threads with similar titles, but I have some differences so I wanted to post a fresh thread. Sorry this is so long.
Got my 4xe April 2021, almost 12,000 miles, 18 months flawless operation! This past Wednesday I started Jeep up and it went immediately into gas mode. I thought very odd, but it was first cold morning this fall 50 degrees, but then it stayed in gas mode whole commute. I tried forcing into electric mode and it gave me the "Electric Mode Unavailable Cabin Cooling or Heating. Drove it back home end of day, it was working normal (mostly auto electric mode) most of the trip then reverted back to gas engine at odd times, and yes I understand it is designed to go back and forth to gas etc, but after 18 months you know your vehicle and you know when this is not normal.
I took it in to the dealer Friday morning and I was so relieved when the service guy said this is a known issue and it just needs a software update......nope! After a two hour wait I was told nothing is wrong, software is up to date and that I had left the heat on the last time I turned the Jeep off and the Jeep won't start in electric mode if the heat is left on. I'm fairly certain I hadn't done that but had no choice at the time but to say ok, and hope it was user error.
So today, started it up and it started in electric mode, I was relieved. Drove to store everything fine, went in grabbed something, came back out and Jeep wouldn't start. The dash screen said its usual thing about Pressing brake petal to start, but I push start button and nothing. Center big screen black, some lights working but won't start. Sat there 45 minutes waiting for tow truck and all of a sudden the various lights inside came on with me not touching anything and it was like the Jeep took a breath of life and I was able to start it and make it home.
Just went back out about four hours later and started it, again its starting in gas mode and saying "Electric Mode Unavailable, etc" Heat and AC were definitely NOT on. So this is NOT the issue just like I thought.
I have another service appointment Monday morning. I'm hoping I can make it out there (about 30 miles).
So since the service advisors/techs don't seem to know how to fix things unless the computer tells them what is wrong (not their fault) and my computer is evidently saying things are Hunky Dory, does this sound like it's the same issue as everyone else and the fix is to replace the "Electric Coolant Heater"? Oh, and I did notice last night I could hear a loud sound in the rear of the Jeep that sounded like a pump or fan of some kind that i've NEVER heard before. it was pretty loud. Is the electric coolant heater located in the rear area of the jeep by chance?
I'm hoping I can get some idea of what to tell them to look at on Monday.
Thanks so much!!
