2008 Mercury Mariner Hybrid transmission problems

We bought vehicle in jan, 2018 from a private party, as a work vehicle for my husband, who is a usps rural route carrier. Two weeks after purchase, the anti-lock brake light went on, and the car would not stop when it was supposed to, which was very dangerous in winter. We believe the prior owner knew about this. The light would just go on & off with no pattern. About 1 1/2 months later, he was driving on a 2 lane hgwy (55 MPH) delivering mail. He went to pull forward but the car made a brief noise and then everything just stopped working. The car wouldn't start, no electrical or lights, he could not even roll the vehicle by himself to a safe place w/out help. The electrical and propulsion simply stopped working; period. We ended up dragging it home. Dealership gave est. Amt of repairs around $18k. I found the recall in 2014 (14s19) for the same thing. The mec pump was replaced in 2014, with a "supplemental" fix in 2015 same issue. This is the exact same issue as the previous recall, which neither mercury or any dealership wants to honor. I'm guessing there are more hybrid mariners w/ similar issues, but not enough to issue a follow-up recall. So here we are stuck in car repair purgatory. I do believe they should honor the recall now and fix the pump and replace the hybrid battery. Not sure about the brakes, but I have seen a lot of complaints about them as well - again, not enough for a recall, which again. Purgatory. My husband was very lucky. Had it been a diff time of day there would have been much more car & semi-truck traffic on the hwy (speed limit is 55) and with him literally just stopped dead in his tracks, there surely would have an imminent risk of a serious rear-end collison, with potentially deadly injuries. I am looking for help, assistance, guidance and anything else from any source possible to resolve this issue. We are at our witts end!!

Quits running while caution with explanation in middle light appears and wrench light appears. Then notification to stop at once safely. This has happened on freeway. After 15-20 minutes car will crank again but may only go a few feet and stall again, near death experience.

2008 mercury mariner hybrid was going 20mph on electric motor in traffic when triangle warning light came on and the stop safely now sign displayed. The vehicle gas engine did not come on and I had to pull over to the side. I place the car in park and turn off the engine. I restarted the engine and the warning light disappeared. I took it to the ford dealership and they ran a diagnostic on it. They indicated it was the throttle body on the car that needs to be clean or replaced, and the PCM needs to be reprogrammed. I replaced it. This is after I took it to the ford dealership to fix the two recalls for this vehicle - electric steering control and electric coolant pump for the hybrid battery. I don't know if this will fixed the stalling issue since other vehicle owners indicated this problem persists, only time will tell. If this is a persistent problem please issue a recall since losing propulsion in traffic is not safe.

My vehicle was part of the nationwide recall by ford this summer. As instructed, I went into the dealership and my car was "given the fix". Not 1 later my power steering in my car has completely gone out. It is very difficult and dangerous to drive my car. I brought my car back to the dealership and was told that my car had already been diagnosed and "fixed" under the recall, so there was nothing further they could do. My car is actually doing the thing that the recall warned about and they sent me away. It has been 4 months, I feel like I take my life into my hands when I drive my car and ford takes no responsibly.

Driving at 50+ MPH on multiple occasions and vehicle gives stop safely now message and suddenly reduces greatly in speed. It randomly has occued and when it has, I had to try to navigate out of 50+MPH traffic after the vehicle suddenly reduces speed to about 20 MPH to a shoulder or other safe area. Had the coolant pump replaced but still occurs. Ford said the twin vehicle the 2008 ford escape hybrid has recalls for the throttle body assembly and blend door actuator for hybrid battery cooling system that have been identified as causing the stop safely now message which because the vehicle suddenly drops from highway speeds to about 20mph could cause serious accidents. Since the 08 mariner hybrid is the 08 escape hybrids twin, the throttle body assembly and hybrid battery system blend door actuator should be recalled on the mariner hybrid also and replaces to protect lives by preventing accidents because of the defective parts.

Just after starting my car and driving down my street at ~5mph, there was a warning symbol (red triangle) and then message saying "stop safely now." the vehicle then lost power steering, and power to the engine. I restarted the car and made it ~100ft and the same thing happened again. This also happened several times previously on the highway traveling ~65mph and with the same message "stop safely now" message appeared and immediately lost all power to steering and the engine. I went to the ford dealership and was told to replace the hybrid coolant pump and blend doors and this fixed the problem for several months until today. I had also just taken the vehicle into the dealership for a recall on the power steering. This loss of power and ability to steer is extremely dangerous! This needs to be recalled!

A "stop safely now" warning message came on when I was driving on the freeway at 60 miles per hour. The car immediately lost power and became difficult to steer. I pulled over to the right shoulder as safely and quickly as possible. This has occurred multiple times.

As I was driving down the freeway, my mercury mariner hybrid displayed a "stop safely now" sign on the control panel. Not even a minute later, the car began to shut down and I had to maneuver get off the freeway. When I parked the car, I sat for a moment and then the car started right up. I drove another few miles and it displayed the same message and then stopped. It started again and then did the same thing again.

For the past 3 years I have been dealing with my 2008 mercury mariner hybrid shutting down in the middle of traffic and giving me the pull over immediately warning. I have had to replace the hybrid cooling system door actuator and the electric water pump (mec unit), all within the past year and half. On june 11, 2014 the vehicle shut down again and gave my wife the pull over warning. I took it to the ford dealership this morning and they said that the throttle body now needs to be replaced and they gave me the error code p1a0c. The funny thing is, this is the same error code they gave me when they said the electric water pump (mec unit) had to be replaced. I checked this unit the other day when the car died and it was functioning properly. There is a major issue with the ford hybrid products and ford refuses to fix them. They sold lemons to thousands of hybrid owners who have made complaints and ford just brushes us off. They just keep telling owners to suck it up and pay to replace different parts. Please make ford take care of these vehicles before somone gets killed because they do shut down without warning, has happened to me numerous of times in heavy high speed traffic and it is not a good feeling.
