Was driving on the freeway going about 70 when I lost all power to accelerate. I noted the wrench symbol also had just came on. I was able to pull over to the shoulder and turn my car off. Before it turned off the car shook quite a bit. I let the car sit for about a minute re-started and noted the wrench was gone and I could accelerate. Later that day it happened to me again. Car is in shop and they told me it is a bad throttle body.

While driving upon a roadway in our neighboring community at approximately 30 mph, my 2010 Mercury Mariner suddenly stopped traveling at speed, and went into 'limp mode'. I was able to slowly pull the vehicle into a parking lot. I called my wrecker service and they towed (flatbed) my vehicle back to the Ford dealer where I bought it. I purchased the 2010 Mercury Mariner new from the same dealer. They examined it and determined that the 'throttle body' needed to be replaced. They declined to repair it under warranty, stating that the part was no longer covered. They also stated that a recall had not been issued. I paid a total of $409.27 for the repair. The tow bill was covered under my membership in aaa.

While driving approx. 45 mph the wrench-shaped warning light came on and I lost propulsion...engine still running, radio, A/C still operating but 0 rpms. I coasted to a stop on a side road and called a tow truck. Mechanic tells me it is a failed throttle body and will be pretty expensive to replace.

When driving at a slow speed of 20-25 mph, the vehicle stopped accelerating and bucked a little. The wrench (powertrain) signal light up on the dash, so I proceeded to pull over, put the car in park, and shut it off. After a few minutes I turned it on again and all seemed fine, though the car was now slow moving and less smooth through shifting. The same thing occurred 9 days later, with the vehicle responding even more slowly afterwards.

Driving at 50 miles per hour the SUV lost all power and had to pull to the side of the road. Turned off vehicle and then restarted and ran fine. Three days later it happened again. Took it to the dealer and they told me it was the throttle body on the motor was bad. They said it wasn't covered under my drive train warranty and charged me $300 dollars. The SUV only has 17,000 miles on it.. I read there is 27,000 complaints about this problem. Why is there not a recall on these vehicles? some one is going to get hurt or killed because of this problem.

  • 48,400 miles
I was driving on the highway at bout 70 mph and all of a sudden, the gas pedal went limp and I couldn't accelerate anymore. I slowed down to about 45 mph with cars flying past me. I was able to move to the shoulder and turn the car off. I had no idea what happened so I called my boyfriend and he came and checked the oil and a few other things but everything seemed to be ok. I got back in the car and it started fine and I was able to drive it home. I am afraid to drive my car on the freeway again knowing this problem could and probably will keep happening until I get the part replaced.

Mariner 4-cyl

  • 95,000 miles
I was driving along on the highway (I-77 N) and all of a sudden my car started to jerk. The wrench tool light lit up on the dash board and the car immediately began to loose speed. The change in power and speed was quick and I had to quickly check the surrounding traffic and pull the car over to avoid and accident. After pulling over to the side of the road I cut the car completely off and it started back up. I took the car to the dealer where I purchased the car and I was advised to replace the filter. I purchased a filter from Ford and my car ran smoothly for about 2 weeks. I would push on the accelerator but it would not accelerate. Each time the wrench tool would appear and the engine light would come on. I have lost speed in the middle of an intersection. After my car started to cut off again following the installation of the new filter I took the car back to the dealer and was instructed to purchase throttle body spray. They cleaned out the throttle body and the car drove fine for a few days until I began experiencing the same problem. Some times I would have to cut my car off a few times and restart it on one round trip. I keep regular maintenance on this car, changing the oil and rotating the tires, etc. I purchased the car in December 2012 because the car I had over $2,500 of needed maintenance. I needed a reliable car to get around as the primary transportation for my family. I took the car back to the dealer a few times and they explained the code and explanation of the problem: Trouble code P2111, throttle body actuator stuck open and closed. I really hope this investigation is expedited and that Ford recalls the Mercury Mariner 2010 due to the faulty throttle bottle. I have had zero maintenance issues with my vehicle other than the throttle body issues.

Driving to work on 1431, the car felt as though it hit a bump, lost all ability to drive. Pulled over to side of road, turned car off for about 10 to 15 seconds and then back on. At this point it seem to operate properly. Then about three miles down the road it did the same thing again. This time there was no shoulder to pull off on, so traffic was tied up. Was traveling at about 40 mph this time. Did the same thing, turned off and then back on and seemed to work normal. Later that evening going home from work the car did the same thing, two more times before I reached home. One time as I was going from palmer to 1431 on a curve. The next time it was on a slight incline going home. The icon on dashboard was a wrench which indicates it had something to do with the throttle control. Took to dealer and they confirmed it was a defective throttle control unit, and charged $650 to repair. Believe that this is/was a serious problem safety wise and should have been covered by Ford.

9/8/2013 driving 60mph I felt a slight jolt and notice a yellow wrench light came on dashboard.then the Mercury Mariner decelerated and stalled to where I was able to move to shoulder off road, and turn engine off. At this point not knowing what to do I just turned car off for about 5 minutes and then re-start. There was no wrench light, but I did notice a hesitation for the car to catch. I drove home about 20 miles and the car drove rough as if it was having a hard time shifting and notice the RPM dancing back and forth from 3-1 on road inclines. Took it to mechanic and had a diagnostic test read no stored codes.what"?" this happen within a 2 day period, car would stall, yellow wrench light would appear on dash. Took it to a Ford authorized dealer, and he knew exactly what is was throttle body malfunctioning. Paid. $301for parts and labor.

I was leaving a soccer game and the car went to about 40 mps and the wrench light came on and the pedal went limp. I pulled over and stopped the car and the car started shaking like it was out of time. I put it in part and shut off the car when I turned the car back on the light was off. I was able to drive 20 miles back and forth and then it did the same thing again. I have taken it to run the codes and there were none. Today 8/31/13 it did the same thing again and now finally the engine light came on. Codes were ran at autozone and P1212 throttle body sensor finally showed up. I had already checked the web the first time that it did it after talking with a mechanic that works at Ford and he told me what it was and that there was no recall. I am very upset. I just purchased this car less than three months ago!!! single mom someone help!!!

I was driving my car merging on to the expressway in a construction zone and as soon as I got on the car completely lost power. I could not push on the gas or anything. Luckily there was an opening in some cones for me to barely have enough power to get out on one lane of traffic in a construction zone in morning rushing hour traffic. I had to turn my car off and luckily it came back on. I have read online that this has been happening to so many people that the part is on national back order. This is crazy! I had my 1 year old daughter in the car and we could have been hit. This is completely unsafe!

Driving at approx 40 mph car engine reacts abnormally and "wrench" warning light appears and car "stalls" out and, although fully operational will not drive. Turn the car off and back on and the engine eventually will turn over but again repeats the same issue of "stalling" out. After having the car towed, the diagnosis is a defective "throttle-body".

While my wife were going out to dinner we were driving on the highway at 45 mph. I noticed a yellow wrench warning light appear on the dash. The car started losing power and began jerking. I could not accelerate and the speedometer dropped to 0. I coasted to the shoulder and stopped. I had to have aaa tow the car to my mechanic. He ran different tests and the readout he got from the computer was the throttle body assembly. He has a priority order for the part and said there is a national backorder on this part. I have an extended warranty with (nac) and they told him they will not pay for the part. I have to pay close to $820 for the part and labor. Ford has known about this problem with the 2010 Mariner but will not have a recall. Do people have to die before Ford Motor Company acts? this is a disgrace for the consumer.

My 2010 Mercury Mariner went into limp mode and would not respond to throttle inputs. I researched this issue and learned that this problem appears to be related to a faulty throttle body or electronic control panel for the throttle body. This an extremely dangerous condition as it appears at random without warning. I believe this must be a defect that has been known to Ford for some time and needs to be the subject of a recall.

Driving at 45 mph and car went into limp mode. Called for a tow truck to my dealer where I bought the car only 6 months ago. They said it was the throttle body. Did lots of research to find this is a huge issue that needs to be recalled. Ford needs to take responsibility before more get injured! my dealer refuses to cover this repair nor can give me an eta because this is on national backorder. Because this happens so much. Too, once the new throttle body comes, I'm sure I'd have the same issue as the part is a defect.

  • 60,250 miles
I was driving at about 25 mph when the car suddenly lurched forward, then began rapidly decelerating. I had to get off the road and coast to a stop. I turned the car off then restarted it and everything seemed fine, but the problem happened again later that day and several more times in the coming weeks. It has happened at various speeds and under diverse conditions. It is intermittent and unpredictable. After nearly causing an accident on the interstate due to this occurrence I am now limited to surface streets and only when I have no other option but to drive my car. After doing some reading it seems that this is a known defect with the throttle body and I worry that even if I pay out of pocket to have it repaired I will only be buying another part with the same defect. My hope is that Ford will issue a recall of the vehicles for which this is a known issue!
