I was driving at 65+ mph on expressway - vehicle stopped accelerating and a violent shaking of the vehicle occurred forcing me off the highway - at this time notice an image of a "wrench" lit up on dash -- I was able to get vehicle to the dealer - not worried due to I still had 2000 miles left on warranty, only to be told this is not covered under warranty. My question is this is huge safety issue and should under no questions be a charge to the consumer. I was charged $309.20 to replace the throttle body motor and assembly. After much research this is an ongoing problem with many of the Ford vehicles. Attached is the invoice that I had to pay. I have tried to obtain the zone rep for my area and I am having trouble getting this info from my dealer. I am still investigating as to how to obtain this info as I believe someone in higher position then dealer needs to be aware.

Intermittently loosing power, intermittent wrench light. Power loss happens when going up hill from a stop or even when at a rate of speed on the freeway. Goes completely limp, but does not shut off. Almost rear ended by a semi yesterday morning. The wrench light goes off and stays off for a bit once you shut the car off, making diagnoses very hard. What once was so intermittent it was thought to be a fluke, is happening with more regularity. And I see other complaints but no recall for this issue, so I know I am not the only one having this extremely dangerous issue.

Our 2010 Mercury Mariner had a clunking and loss of power on two different occasions. The first time we brought it to the Ford dealer and he checked codes, etc, only to find nothing. The clunking or loss of power did not came back for a while. Several months later while driving home from work, the clunking sound appeared again, there was an evident loss of power and the orange wrench displayed on the speedometer indicated an issue. I had to work on getting the vehicle up to speed and power again, slowing the traffic in back of me down. The vehile was purchased a year ago, almost to the day and has approximately 52,000 miles on it. I called the Ford dealer who made arrangements to bring the vehicle in for a check up. Based on what I'm reading, these are known issues with a throttle? not certain if there's a recall or not but will certainly find out. Basically, our vehicle is unsafe to drive.

I was driving my 2010 Mercury Mariner premium fwd to my mothers for christmas '14 when the engine light wrench came on and I felt a loss in power. Luckily I was near a rest stop and I shut off engine and let it sit after running a vehicle health report. Report said: Urgent power train malfunction / reduced power. After restarting the vehicle, it seemed fine. This was when I still had about three hours left of driving in my eight hour drive. When I was about an hour away again the light came on and the same power reduction occurred. I took it to be looked at to the local Ford dealer near my mothers and was told the valve body needed to be replaced. This was at 74,000 miles. So I did. I had this happen once before (I had 58,000 miles on it) when driving to a shopping center after driving 45 minutes on the highway from home. Only happened when driving long distance. When I got off the exit, it jerked and quickly stopped and I had to pull over. If a car was behind me it could have caused an accident.. I drove it to the dealership and was told that I had a couple recalls (computer updates) and a service extension for the throttle body. Should fix the issue so it won't happen again said the mechanic. Transmission fluid was flushed cause it was burnt also. Had no issues afterwards until my christmas trip. I feel I could have been in an accident and seriously hurt if it had jerked while changing gears on a busy road. I would like to know why there is a throttle body recall but not a valve body recall? if these issues can cause a quick jerk or lost power causing a quick slow-down, seems like there should be a recall for both. It appears I am not the only one with these types of issues after googling the issue. Seems like its time to get these transmissions fixed correctly before someone is killed or seriously injured! please recall now B4 it's too late!

Coming to a stop at a red stop light and then trying to accelerate from red to green light at an intersection my vehicle went into limp mode, it lost power. It would not accelerate pass 10mph. An engine light came on as a orange wrench light. I drove as I could and made to auto zone. They plug in the hand held car computer and it gave the code P2119. Which stands for throttle body.

During normal driving on the highway the engine lost power, the wrench light on the dash lit. The vehicle sputtered and suddenly decreased in speed, making for hazardous driving conditions. I moved to the side of the 4 lane highway and into the breakdown lane. I placed the vehicle in park, the engine idled roughly. I turned off and restarted the car and the symptoms were gone. A week later the same trouble returned. Please press fmc to resolve at no-cost to consumer the obvious and dangerous manufacture defect with a recall on the affected parts/system.

Was going home from work, about 20 mph, car sputtered and stopped accelerating on ramp, engine and wrench light came on. This had happened before so I knew to turn the car off and back on to get my car to work again. But alas, I am driving at about 30 mpg for only 2 minutes and it happens again! I was again on another ramp, completely blocking traffic. Thank god I was not yet on I-95 going at a high speed, or even worse with my child in the car. If I ever get in an accident with my child and we are injured because of this, my family will sue the heck out of Ford. Has to call my husband to drive the car to the dealer after I pulled off the road, I was shaking too bad to drive.

My 2010 Mercury Mariner has started jerking when I attempt to slow down. It is jerking unbearably hard. I took it to a local garage, had both front and back brakes replaced. That did not fix the problem. While the backend of the car is jacked up, the back right wheel will still turn while holding the brakes"?" the jerking of the car is almost as if the car is skipping a gear or trying to switch gears. The car is also making a whinning sound. I feel as if this is a safety issue that Ford should be responsible for. This is my second Ford SUV with my first being a 2002 Ford escape and I had a lot of "mystery" problems with it that no one could fix!!!

Twice in two days while speeding up to get on highway my Mariner looses complete power and the wrench light comes on. Lucky for me it was just before I was turning on to merge. Seconds later it would have been a serious accident, due to the sudden stop. I had to shut the car off and start it back up in order to get going again. After reading #PE13003 has been file for the same exact problem with same make and model. Someone better react before someone looses a life. This is horrible.
