Today, I was doing great on a 60mpg plus tank and started a recal event. I had a 43% SoC when I noticed I couldn't go EV and the battery SoC started climbing. I got to a 58% SoC , but it would climb no more. Still could get regen, but MG1 would not let it go any higher with the generator. Then I noticed I got motor Assist during acceleration and the battery SoC would drop. Still, no EV mode and I was in this horrible drop in MPG with a battery SoC in the upper 50's. At first, I thought my Hv battery went south, but I noticed my battery fans running hard. It only got to 81F here today, but a recal could heat-up the generator if the Electronic Coolant Pump failed. Also, the battery could be over heating if the battery A/C wasn't working. Looks like a first for me at any point. I'll be doing some more test to see what the problem is, but does anyone have any guesses?

So you think it was a recal that wasn't completed because of an external fault?
What was on the odometer? or pehaps not a recal and somehow just went past normal
SOC during regen?

 

I think overheating of the generator or HV battery was preventing a recal completion. I'm still stuck in this mode until a cooling matter is repaired or the HV battery is replaced. I'm leaning to an Aux A/C issue, but have not had any time to investigate yet. My odometer is at ~30,100 miles, but I don't think that is in play at this point. I never run my cabin A/C, but the Aux A/C runs all the time in my hot weather. I've never had a battery blend door trouble, so I don't think that's an issue. This is the first time for prolonged non-EV mode, so heating must be the problem.

Okay, I haven't had time to test the MECP or the A/C, but when I came home today I think I'm closer to knowing what was causing the EV problem. Under the left front of my '09 FEH was a large wet spot and something is now dripping. This just started within the last 4 hours and it appears to be MECP fluid. I haven't started or moved my FEH since I parked it before my post here. I haven't heard that the pump will leak when it goes bad (anyone?), so it might be just a leaky hose or something.

I thought in the 2009 and newer Escape Hybrids they had an entirely new pump that was to solve the problem some of the older models experienced.Is this not the case?

 

I doubt it is the blend door since you'd get the service light and wrench, I just replsaced mine @ around 30k. I was getting intermittent service light. pretty easy repair, definitely no a $800 dollar job, took less than 45 minutes.
If it was the A/C wouldn't it go back to normal after cooling down to ambient temp over night?
