I ordered a BlueDriver Pro as it seemed to support the Jeep better than many others.

There was someone else that recently mentioned using that and not being able to pull the ech lockout status up.


Maybe it'll let you run jscan through it.

I checked and it was not supported. I cancelled it and verified the OBDLink MX+ OBD2 reader and it says it is supported by JSCAN. I guess I assumed the BlueDriver, since it said it had enhanced coverage for Jeep, that it would cover the stuff you referenced. Thanks for the reminder to check.

Obdlink is definitely good to go

The heater being locked out is almost always the cause of this and requires heater replacement. There is a star case that gives the dealer the specific instructions on how to diagnose it. Takes all of about 5 minutes to verify in software. You can also verify it yourself with an obd code reader that'll show you pid values.

Been having this problem for about three months now. After three visits to the dealer, they finally acknowledged last week that the electric coolant heater needs to be replaced. But I was also told that they won't have the part available to make the repair for at least a month, maybe more. Anyone else with this problem being told this? Have a feeling I am going to be chasing them down to make this fix for awhile.

Were you have the same message in this post ("Electric mode temporarily unavailable") or the "Electric Mode Unavailable Cabin Heating or Cooling" message from the other thread. I am not sure they are the same thing.

For the first few months, I was exclusively getting Electric Mode Unavailable: Cabin Heating or Cooling. More recently, I've been getting Fuel and Oil Refresh Mode: Electric Mode Temporarily Unavailable. Sometimes (like tonight), got one then the other during the same drive. I just picked up the car last week from the dealer. While it was in they did the software update associated with the recall. Now my check engine light is permanently on. According to my service manager, this is because the software update has made it so that the vehicle's diagnostics system now recognizes that there is a problem. At this point, the vehicle is running almost exclusively on gas. I can go over a week without needing to charge the battery.

Your electric coolant heater is likely defective, take it back to the dealership and get them to replace it

Ok, I think both of these are different than this post. There is another thread on the cabin cooling message active right now. For FORM issue may be normal operation and not indicative of an issue.

Your electric coolant heater is locked out. You're probably also in FORM. The recall software update now triggers a check engine light for a locked out coolant heater.

The fact that your service advisor didn't say "your electric coolant heater is locked out, we have ordered you a new one" after doing the recall and seeing the light says you need a new dealer to go with your new coolant heater.

Dealer telling me that they won't have any replacement electric coolant heaters for at least a month, probably longer. Curious if anyone else is hearing this from their dealers.

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.

Hi Kate
I have had this problem 3 separate times since I bought this Jeep in July 2020. I brought it to the dealer in MA and they fixed it, but then it reoccured months later. I brought it to the dealer in Syracuse, and they seemed to fix it, but then it reoccured months later. It is at the dealer now to address the problem again. We bought this car so that we could run on electric most of the time, as we don't drive much more than 30 miles before returning home. Any ideas on how we can fix this permanently?

What did they do to "fix" it? Have you verified your ech lock out status?

Sorry, what is each lockout?

 

[Mllcb42]

ECH lockout. Electric coolant heater.

 

[Thedonkerslayer]

So your vehicle didn't come with this? It also states when it might not operated in electric. You would be foolish to think you could purchase a PHEV and except it to drive in electric mode 100% of the time because you think it should

No, it did not. Plus that says nothing about it being "too cold". I understand FORM and the reasoning electric mode would not be available because of that, but it being too cold outside is not anywhere in any literature I have, nor was it ever disclosed by the dealer.

 

[Tyler-98-W68]

Ignorance is no excuse, all the information is out there, there is no help for you, no amount of information is good enough for you, just go buy a EV and find something wrong with it to complain about

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.

There is now an active recall for that specific issue. You should get the notice in the mail soon if you haven't already.

I had same problem. My dealer will change my Electric Coolant Heater. They can't tell me when this item will arrive. They gave me a replacement car.

Jeep 4xe Owners Are Mad Over Electric Mode Not Working in the Cold

Some claim their plug-in hybrid Jeeps haven't been able to engage the electric-only driving mode this winter.

And if people take the time to read all the testing and research I've done, they would fully understand why the 4xe behaves the way it does in the cold
