Problem Description and Possible Solution
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.
Average mileage: 88,645 (25,000–223,390)
Electrical & Lights affected: 2.3L 4 Cylinder

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.

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 me....like 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?
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.
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.
"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...
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!
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!
Same situation as described above. Need help!
Cooling pump failed and shut off engine. Cost over $800.00 for dealer to repair!
going down road and dash said pull over safely and then engine shuts off.
My engine shut off three times going highway speeds. Was able to drive and had the card towed to avoid more damage. Still waiting to go to the dealer to get this problem "identified"
Same Problem. If I drive under 45 mph, car runs fine. By as soon as I get on the highway..it stops. Im reluctant to take it to my local dealership because Ive have a bad experience there before. So, if anyone can help me....the problem is most likely the MECS pump? And I could replace it myself?
Coolant pump failure. Same description and solution and $800 repair, not covered under hybrid warranty. Aparantly a revised pump design.
At about 120,000 miles my Check Engine light came on while driving on highway at high speed and moderate traffic. The engine cut out & I had to coast to side of road. Cooled off engine, but same thing happened again. On-line owners cited this as well, called it the "triangle of death" light. Got it fixed immediately, very expensive. A year later Ford issued a recall on this part, luckily I was compensated.
Took car in for service in March 2011, was told battery was not holding enough load. Forgot to get new battery, and the "stop safely now" message and engine shutdown occurred. After battery replacement no further problems until . . .this past weekend in the fourth hour of a 5 hour road trip, while driving on the interstate, the "stop safely now" light went on, and the engine shut down.
I pulled over. Turned off the engine, then restarted the engine and finished the last part of the drive home without incident. Just took it to the dealer in my city (Veracom in Burlingame, CA) who says its a electric motor cooling pump and wants to charge $1100 for the repair. I have mechanical breakdown insurance, and I hope its covered. Seems like the going rate is $800 based on what I've been reading here.
car shut down when overheated and fan in back hybrid battery would not go off. It was replaced and now it has started to fail again, one year later. Now i have to pay another $180 to get same problem diagnosed and they will fix it but I have to pay for labor. I will not buy another Ford vehicle. also rear wheel wells are rusting and they suggested that I not get it fixed because it will come back.
**READ THIS BEFORE YOU DO ANYTHING**
There is a recall for this issue. Call your Ford Service Center. Just saved myself a lot of headache and money.
I had the recall of the MECP done and it started the giving the hybrid light.
Searched for solution on web.
Changed coolant pump myself.
Recall came 2 years later.
I had the coolant pump replaced. Now the car will not go into the Hybrid mode or Elc. mode.
