Does anyone have any thoughts on what the parameters are that cause the "oil maintenance mode" to kick in and force the ICE to run? Yesterday morning it kicked in and stayed on all day. I only had ~225 miles on the vehicle. It was still on this morning, but as I was coming back from a site visit (~30 mile round trip), the EV finally re-engaged. The manual was pretty useless since it implied this could be reset after changing the oil. Ummmm, not at only 225 miles am I changing the oil!
The frustrating part was how poor the acceleration was when it was in the gas engine only mode. We have a couple of small hills in town and I felt like I was going to have to get out and push it up them yesterday.
I had seen that someone else has posted about this several months ago - sounded like temperature could be a factor. Our winter weather is NOT leaving and it was 14 degrees yesterday morning and about 17 this morning. High never got above 25 yesterday. We might break freezing today.
I understand the concept of why this mode needs to run periodically but really would like to understand how frequently I should anticipate it.
Do you have a level 2 charger or are you just using the 120V one that came with the vehicle?
The Battery Pack uses cabin air to heat / cool it. If the ambient air in the cabin is too cold, I am pretty sure the EV mode is disabled
until it warms up. Someone from a colder climate should weigh in on this.
I took delivery of my vehicle at the end of December, it was really cold by CA bay area standards.
My vehicle is outside at night, but plugged into a level 2 charger. The first really cold morning I went to drive
the car, EV mode was disabled and the ICE (engine) started and ran until the cabin warmed up a bit. Then EV mode became available.
After that I used the remote start and ran the vehicle for 10 min, with climate set to 70 deg. (The my ford mobile app wasn't working yet).
Now I have a go time programmed in with a temp of 65deg. Note: Doing this with the 120V charger will run down your battery pack.
I currently have 2800+ miles on my car, now that you mention it, I realize that the engine kicked in far more often in the first 1000 miles.
Never got any messages though.
Did you happen purchase the engine block heater option for your vehicle?
I don't understand the message, unless there is a freeze (too cold) parameter the engine controller uses, and decides it must
run the engine to cycle the fluids. These vehicles use electric heat for the cabin climate control, so running the engine
does not make sense.
