Jgpranch Posted March 4, 2024 at 11:20 PM Report Share Posted March 4, 2024 at 11:20 PM For the last few days the EV mode will not work even thought there is a full charge - I get a "Maintain Engine Oil" notice and press OK and then the car drives in ICE normal mode. I just had the engine oil changed about 2 weeks ago and it is fine - is there another oil I need to chck for the Electric motor?? Quote Link to comment Share on other sites More sharing options...
jsamp Posted March 6, 2024 at 06:24 AM Report Share Posted March 6, 2024 at 06:24 AM (edited) You have to reset the engine oil counter. On my 2015 you use the left dash screen and the left steering wheel buttons to select these options: Settings > Vehicle > Oil Life Reset. Then hold the middle <OK> button for 5 seconds to reset. I've not heard of this preventing the car from going into EV mode though. Not sure if this will fix that issue or not. Let us know.

Not sure if this will fix that issue or not. Let us know. I know on my C-Max, the oil maintenance mode does keep the ICE running 100% of the time even at stops. I imagine the behavior shouldn't be any different with the Fusion. But yeah, sounds like the oil life monitor wasn't reset. The above instructions will do it and should kick it out of that mode. Just an FYI: This should ONLY be done after oil changes. Do NOT do it just to end the oil maintenance mode. This mode is designed to run after the ICE has been repeatedly run for short intervals and not allowed to reach full operating temp. It then runs the ICE 100% to boil off the moisture in the oil accumulated from those short operations. And it'll continue to run even after vehicle restarts until it is satisfied. It basically wants to get to full operating temp for a certain period of time (I don't think this has been documented and I haven't seen anything in the copy of the service manual I have for the C-Max) before it'll end. jj2me 1 Quote Link to comment Share on other sites More sharing options...

I tried this but it did not change the behavior of the EV mode and I still continued getting the message.... Quote Link to comment Share on other sites More sharing options...
