I was traveling along, with my daughter in the car, when it seemed to just shut off. I was only going 40mph but in a line of traffic. I pulled the car over, it was then I could tell it was sorta still running. I come to find out later it went into a safe mode. Since then my wife or I have barely drove it. We had a close friend check it out and it is the throttle body. I then did some research online and come to find out it seems I'm not the only one with this problem. Is anyone out there making Ford Motor Company responsible for this" I called the dealership, where we purchased our vehicle new and was told there was nothing they could do, unless I paid for this. I feel this is unfair! my wife and I purchased this vehicle brand new with only 8 miles. Why should we be punished for what clearly is a defect in a Ford product" please help.

I had just gotten back from a long trip, and was stopped at a red light - I barely accelerated once it turned green, and the car lost complete and total power, in the middle of the intersection. A wrench light came on. No throttle was working as much as I pressed down. The car kept snail pacing until I got to an empty parking lot where I turned the vehicle off. I turned it back on and it revved itself, so I turned it back off. Turned it back on and all of a sudden it worked again. I took it to the dealer who claimed it was the "electronic throttle body" failing and charged me $98 for the diagnostic. I decided for a second opinion, and they took everything apart to see if it was something else since the car is only 3 years old and only has 30,000 miles on it. After much testing they concluded it was in fact the "electronic throttle body, " and the repair cost me $595. Before this happened, 2 or 3 days prior, I felt the car was losing power and it was hard to get it to go at its V6 potential. Car still hesitates and feels like the engine jumps out when it stops and moves again... sure enough my engine mounts now need replacing, and that's anywhere between $350-$500. Another recall perhaps? it's been doing this since day 1, and my warranty ended about 6 months ago. Go figure... just when 3 years was up! sigh

I purchased my 2010 Mariner 03/26/2013 from a local dealership. While driving at around 35 - 40 mph I noticed a grinding sound and difficulty to increase speed. I then noticed that my left blinker was flashing at a faster speed and the tail light went out. That was replaced. The car then would sporadically go dead and would have to be jumped. I had 3 different service shops look at the vehicle and found no issues. I did replace the battery and it appeared to run fine for about 3 - 4 days. It is now sporadically dead and the local dealership will look into the issue on 8/7/2013. Undetermined problem at this time.

My daughter was traveling in Louisiana on business, when for no reason the SUV stopped on the interstate she phoned me in tears on the issue, she was stranded on the interstate for a short while. She got it started again after a few minutes. She drove for another few miles and it did it again. She finally made it to a dealer. The dealer ran a test that cost her 125 dollars only to tell her she had a bad electronic throttle body assembly. They informed her that the part was not available and would be days maybe weeks before they could get one. She than returned to her place of stay, that took about an hour because she could take the interstate and had to stop every few miles to restart the engine. What a huge inconvenience and frightened she would be rear ended. I hope a resolution is in the works for this safety issue.

Car went into 'limp mode" at about 25 mph and the orange wrench warning light came on. Had to stop, turned off the engine and then restarted. Warning light went off but it occurred again in about 5 miles. Went to Ford dealer the next day and they could not find anything wrong nor duplicate the problem. Problem happened again a couple of miles after leaving the dealership. I immediately returned to the dealer and they once again couldn't find anything wrong. Two days later on I-95 the car went into "limp mode" the orange light came on and I drove to the side. The traffic was backed up so I was going about 25 mph when this occurred. When I restarted the engine this time, the "wrench" warning light went off but the "check the engine" light came on and remained on. Next day returned to the dealer and this time they said they found the problem and it was the throttle body. In researching on line I found that this is occurring with some frequency and would certainly like to see Ford take responsibility for issuing a defective part. As of now it looks like I will have to pay the bill and hope that the new part is not defective also. It is a real safety issue and hopefully this will be resolved.
