Ford Escape Hybrid Problem
78 Reports
Me Too

Model Years Affected: 2005, 2006, 2007, 2008, 2009, 2010, 2011

Electrical & Lights Affected: 2.3L 4 Cylinder

Average Mileage: 83,712 mi (25,000 mi - 130,000 mi)


The hybrid models have a coolant pump that cools control electronics. The pump can fail or spin slowly, which causes a Check Engine Light to illuminate and complete engine shut down.

    Same problem as everyone else. After some digging I found this blog and sent it to my mechanic. He replaced the pump and total bill was around $450 because he couldn't locate a cheaper pump quickly. If I had time to wait for a cheaper pump to come in it would have been about $100 dollars less and he said it was truly something that I could have done myself.

    Engine shut down. Coolant pump was problem and dealer charged over $800 to fix. Later checked on line and found I could do it myself for $200 amd 1 hour of time.

    Coolant pump went out to the tune of $703.00, Auxiliary motor went out, $303.00, then recommended HV Filter be changed $30.00 and rear brakes $331.00. How's that for a 3yr old car where we have been the only owners. How does all that happen in a 3yr old car? And they wonder why people do not want to buy Hybrids. My car literally shut down on a computer. Then was able to restart again no problem. Sounds way too fishy to me that this many people are having the same COSTLY trouble with these cars and there has been no RECALL?

    Car displayed "Please stop now!" and began coasting. Pulled over turned off engine and restarted, care operated normaly for about another 15 miles before stopping. Dealer wants $800 to replace electric motor water pump!

    No solution yet as dealership states that my door to door extended warranty does not cover the MEC pump
    VERY VERY Dangerous situation as the Pump has been found to shut down the entire system.
    I am taking the car back in the AM as my daughter also drives this car and is only 19 years old!!!
    They will replace it at no cost tomorrow or I will not leave the dealership. My husband was WAY to nice about this issue as he thought they would do the right thing. What they did is a diagnostic and banged the pump for 130 dollars and said it will probably still need to be replaced! Oh no They do NOT want to see me coming tomorrow. Good luk to the rest of you as this is very dangerous and i wish you all safe driving!

    "Stop Car Safely" Message Came on dashboard. Car would not accelerate. Said Motor was too hot. Pulled over and waited half hour then drove 50 miles without ac on. No further incident that day. Took it to dealer service and was told "DTCS POA81 and POA3C MECP Cooling pump faulty and high voltage batter pack cooling fan failure."

    The quote for parts and labor was $1492. This was 2 days after I finished paying off a 60 month loan. Certain Hybrid Cooling system components are covered by Ford Factory warranty for 8 years 100,000 miles but guess what, not the two parts they said I need to replace. Those parts are 8C419 and 10C659.

    I paid the dealer $129 for the Diagnostic and then drove the car home without getting the repairs. I am calling other dealers to see if I can get a second opinion. There are other comment boards saying that it may be an "Actuator" and that might be a must less costly thing. Seems like other people on this message board did get these parts replaced but the problem persisted anyway!

    Meanwhile I am still driving the car around town and praying the incident won't repeat itself...

    My 08' Hybrid Mariner completely shut down, it just gave me a " please pull over now". I let it sit for like a minute and then restarted the engine and it drove a good 10 minutes at about 40 mph but as soon as I accelerated above 45 it gave me the sign again, and I had to repeat the process. I drove it home on the access road staying between 30-40 and Thank God, it made it home. We had taken it to the dealership about 1 week ago with the same problem and they were very certain that it was the battery fan. But....I guess they were wrong. We paid about 340 for that, but we will see what they say tomorrow when we take it in again.
