Hello everyone! I recently purchased a 4xe and I have about 2000 miles on it and everything was great up until this mornings commute. I was driving on the hyw in all electric mode going about 60mph when all of a sudden the gauge cluster lit up like a christmas tree and the jeep lost all motor power (electric and gas). I pulled off to the side of the road. I got a message about the hybrid system needing to be serviced along with a red wrench and CEL. I was able to turn the jeep all the way off and get it into park. I tried to restart the jeep but no luck. I tried two more times and on the last attempt the jeep started back up and I was able to get to work although I was unable to use electric at all. So when I got home I got my obd II scanner out and I pulled the following code (P0CA6) but the scanner had no idea what the code was and so I searched google and couldn't find anything there either. I was reading about some other owners of jeep having issues with the fuse box having loose fuses so I went ahead and checked that out and sure enough multiple of my fuses were loose or almost out of place. So I tightened all of them down and checked to see if the CEL was still there and sure enough it was. At this point I was able to charge the jeeps battery up to 100% so I plan on taking it for a drive to see if the code clears or if any other issues arise. I attempted to get in contact with my service dep but had no luck as no one answered the phone so perhaps I will just drive down and try to speak to someone in person. What are your thoughts on this issue? seems like lots of new 4xe are having similar issues. I will post updates on this post as soon as I find the fix with the local service dep.
I had an almost identical event yesterday AM heading to work. I was maybe 3 miles out from work driving on I80 East in Des Moines, IA., just prior to the ramp to head North on I35 to Ankeny, I selected Electric mode on a slight up hill the engine cycle off like normal but electric mode seemed sluggish (a bit soft and under power). When I made the turn North on the ramp to I35 I experience exactly your noted situation. With any power I lucky to coast out of traffic to a grass median area between two high speed on ramps (not a great area to park). I powered off the 4xe and then back on and on the first try the engine started immediately and electric mode was not available. I was able to make it to work and tested for electric mode a couple more times even after a restart, that was a no go..... I decided to try charging it up from the 25% SOC (state of charge) and it was able to charge to 100%. I then powered it on and immediately the engine started so I let it idle for maybe a minute or two and tried electric mode, not possible once more. On the next power down and up cycle I got a somewhat normal power on with battery only and no IC engine. I did here some contractor cycling under the hood then that halted and everything seemed normal. I have not checked the ODB codes with my OBD2 Bluetooth reader but plan that tonight. Today everything has been 100% normal. I did report the issue yesterday with Jeep Cares and got a case number for my pending service appointment next week.
Crazy to think but maybe I forced an issue switching to electric mode from hybrid under a moderate Kw load and freaked the power management system out with only a battery available which did seem sluggish from what I have seen as normal electric power at only 1500 mile so far.... I will see what if any codes I find.
