“After having a new water coolant pump (the fourth one in my Mariner Hybrid) and a new throttle body being put into my car by a ford dealership, my car is still having the same problems. Now a service emission sys warning has come on, and being under 150,000 miles still I contacted ford to see what could be done since it was fixed by them but still has a problem related to the electrical hybrid powertrain, and ford says there is nothing else that can be done, even though it clearly is under the warranty that they created due to the failures of both parts.”

“While attempting to exit a parking lot (driving at less than 5 MPH and making a right turn to leave the parking spot), the steering became very hard to turn. Thinking that the engine had shut off, I restarted the engine then I noticed the message in the cluster service power steering . I drove to the nearest repair shop a few blocks away and they confirmed that the power steering module is bad and will have to be replaced. They estimated repairs would cost about $1200 if they can find a used one. I was less than 5 miles away and continued on home. …”

“My son was driving to his work as an emt. I allowed him to use my mariner. Traveling approx 65mph on the 5 freeway south in sunland, he heard the rod go and saw the lights on the dash indicate the engine overheating. He pulled off the 5 freeway and parked wear it was safe and called for help. I had aaa pickup the vehicle and bring it to the mechanic in westlake village ca. They indicated to me that the engine had thrown a rod and would need to be replaced. They thought it might have run out of oil or something else, but bottom line was that the engine was destroyed. …”

“Car would not move at all after coming to a stop when making a left turn in the middle of an busy intersection. With the car idling at 1000 rpms, it would not move when I pressed the accelerator. I had to shut the vehicle down completely, restart it, and then it would move forward only if I pressed the accelerator immediately after restarting. If traffic did not allow immediate travel, the car would not move forward as previously described. If you could not proceed immediately this cycle would continue multiple times. This has happened on over 30 separate occasions with this vehicle. …”
