I am experiencing the same issue with our FEH 2007. Has about 60K miles. Always has gotten less mileage in winter from summer due to engine having to heat up before turning off. However, it is summer, 80 plus temps and the engine is not turning off when the battery is fully charged. It continues to idle at 1000 rpms. Plus I am noticing the on/off being inconsistent, where on one trip it turns off and other times it does not. I'm guessing it is a sensor of some type that is malfunctioning, but this is a guess. I have not brought it into the dealer yet, but will be checking.

These issues sound like the electronics cooling pump (MCES) not working right. Also, the blend door actuator (for models prior to 2010) may not be working correctly.
 
If the battery gets too hot it won't operate.

I got the MECS and blend door actuator yesterday at the dealership for 1157. parts 496 and labler 680$ for what had to be 2hour of having it and 1 hour of work based on dropping it off and when they called back.
 
TSB 08-24-5 states that some 2005-2008 Escape Hybrid and 2006-2008 Mariner Hybrid vehicles may exhibit a red triangle light and codes indicating a transaxle overtemp. This condition may result in reduced power as the system activates fail safe operation. Codes P1A0E, P1A0F, P0A3C, P0A3E, P0A7A, P0A7C and P1A0D may also be set.

#115 of 116 2008 Ford Escape Hybrid starter problem by lehuakea

Mar 28, 2013 (9:03 am)

I'm the original owner of my vehicle and I have had no problems whatsoever--I'm a happy customer. Now, I'm a bit frustrated as my car is not starting consistently. When I turn the key and it doesn't start, I sometimes hear clicks coming from the rear of car passenger side. But sometimes there is no clicking sound and no starting either. I've taken it to 2 mechanics, including a Ford dealership/service center. The first mechanic replaced the battery (not the hybrid battery) and that seemed to solve the problem--the mechanic turned off the ignition and was able to start it 30 + times. Then I drove the car home and was unable to start it. I had to try several times. Sometimes I sit for 5 or 10 minutes and then it will start. Ford has been unable to diagnose the problem because every time I take the vehicle in, they are able to start it on the first try. It does not seem to matter if the engine or air temp is warm or cold. Any ideas?

Check the voltage on the battery. It is possible that the 12v battery is not getting charged correctly.
 
However, on the FEH the 12v battery does not start the engine; the main traction battery does that. All the 12v battery does is power up the electronics to control the vehicle so that the big battery in the back can crank the engine. So you could have a bad traction battery. On a 2008, you would still be under the hybrid warranty for the main battery (unless you have more than 100K (150K in CARB states) on the vehicle. So that main battery would be under warranty.
 
Take the car to a Ford dealer who has Hybrid specialists. This car is very different than a normal vehicle.
 
I did a search on the Internet, but I did not find out how the 12v is charged (via the main engine or via mechanical charging). I suspect that the electrical system charges it, so lack of charging could be the main battery. If it is charged by the electrical system, there could be a problem with the pieces that step the 330v down to 12v. But this last part is conjecture.
