I was driving when it felt like the vehicle was reving in park then the "wrench" icon appeared on my dash. I went a couple blocks & my vehicle felt like it wasn't shifting automatically as it should. I pulled over & turned it off. It started right back up with no lights on, I went half a block & stopped at a stop sign but while stopped the engine reved up. I was worried I was going to be in an accident. Then the "wrench" light came back on, since I was close to home I figured I'd just try to get home. About another block, the check engine light came on & was making strange noises. I kept my vehicle at about 5-10 mph & got it home. My car was very jerky.

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!
