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.
2010 Mercury Mariner acceleration complaints
Page 2 of 3: complaints 11 to 40 of 66, newest first, as owners wrote them.
In 2011, while driving at approximately 60 MPH, I pressed the gas pedal and could not accelerate. The engine stayed on but I could not accelerate. I was able to turn on the hazards and pull off to the side of the highway. I turned off the vehicle and after waiting 5 minutes I restarted the vehicle and the gas pedal was working. Then again in october 2013, I was driving approximately 30 MPH when I lost acceleration capability. This time the throttle body indicator light was displayed. I took the vehicle in to a mechanic and he stated that nothing registered on the computer as a malfunction. He looked at the intake valve and could not see any build-up. In january 2014 this happened 3 times and I was able to restart the vehicle and proceed. However, on january 11, 2014 after the malfunction the vehicle did not reset immediately now the check engine light is displayed.
When accelerating through an intersection, my vehicle lost acceleration power and the power brakes failed. After restarting the vehicle, the vehicle was slowly moved to a side street, backing-up traffic on the busy street. The vehicle was towed to a ford dealership and the diagnosis was that throttle body needed replacing. The service cost me $503 plus tax.
The vehicle shut off while driving. This re-occurred several times during the next 8 days also while driving, one time while making a left hand turn across oncoming traffic. We researched the problem and had two estimates done and contacted ford motor company. The throttle body had to be replaced and the repair cost us $400.00 dollars. We have researched this problem and have seen that this is a very common safety problem. We spoke with our neighbors who have a ford escape and already had their throttle body replaced as well for the same problem. We were told by the dealership that the new part is designed differently now, so this should not happen to us again. This has to be a recall item. It is obviously a manufacturing defect and is a huge safety concern. Ford should have to be responsible for these charges. We are very disappointed that ford has not taken responsibility for this issue and that all of us have to pay for a defective system that ford motor company knows is a problem, and could have been the cause of a major accident.
Was at stop light completely stopped. When the light turned green, I stepped on the accelerator and my car did not accelerate. The engine light and another light came on. I tried multiple times to move the car and nothing happened. I powered my car down and restarted it, at this time the car started moving again when I pressed on the accelerator.
Going 65 miles down interstate during rush hour traffic and lost all power had to weave to side of road to get out of traffic had to have repaired was throttle body.
While driving in heavy traffic in center lane of three line highway. Vehicle suddenly lost power creating a emergency situation. I had to force traffic to allow me proceed to side of the road. Endangering myself and my family, I sat for about 30 min. Before I could move the vehicle.
My wife was driving in town and the car began to "buck" and slow down. After a few minutes the accelerator had no effect on the engine. It appeared to be idling only. She pulled off the road and stopped the car, waited a10 minutes or so, and started it again. There was no difficulty starting the car, but again the accelerator had no effect on the engine speed. We had the car towed to the local dealership where it was diagnosed with a bad throttle body and throttle motor. The repairs cost approximately $500.
Car stalled while my granddaughter was driving on the highway. It also did not accelerate. She had to step on the brakes to get the car to move. She immediately got a diagnosis from auto zone (throttle body system open- p2111), then took the car to the ford dealership where the problem was confirmed and repaired. An emergency light came on during this problem.
I have been having a problem with my 2010 mercury mariner for over a month. It is stalling out at random times and then the vehicle dies. Took to dealership several times and the computer is not detecting the problem so they cant determine what to fix. The dealership says it may me the throttle body, but this is not covered in my extended warranty and is a very expensive part to replace. I am a single mother with 2 kids and this is very dangerous when we are driving down the highway at 75 MPH with traffic.
The vehicle started to stall when the accelerator peddle was engaged, after turning vehicle off and restarting it would travel approximately 50 to 100ft. Before again stalling.
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 300.00 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.
I was driving on a very busy avenue at about 5:45pm and my vehicle stopped accelerating. The wrench light appeared on my dashboard and my vehicle was basically putt-putting down the road at a very slow speed. Due to the fact that my vehicle stopped accelerating, I was almost in a very bad accident. I was able to pull over to a parking space about a 1/4 of a mile and shut off my car vehicle. I called my local repair shop and told them to expect me. I had plans of having the car towed. After about 5 minutes of having my vehicle off, I tried to start it and it was running normally. My repair shop test drove the vehicle and the next day and didn't find anything wrong. They also didn't find any codes appearing in the vehicles memory. They did find an article online about the same thing happening to the same type vehicles. I called my ford dealership and they said there were no recalls and were going to check if there were any bulletins. I am waiting a phone call back.
Throttle body is gone I get the p2111 code this part is costing me 440.00 dollars the warranty the company sold me does not cover it and that is a joke also.
Driving and the vehicle just slowed down and was not getting fuel. I pulled to the shoulder the car was still running but not getting fuel. I turned it off and restarted and it was ok. A few weeks later it did it again and I called a ford dealership to have it checked out. I wanted to get it taken care of before the warranty expired.they said they could not find anything wrong. I had a couple more issues but I did not drive it much during colder weather. In june of 2013 I had another incident with the same issue. Over the next couple of months it continued occasionally but in august of 2013 it started more often. One incident was in an intersection that was very busy and I called the same ford dealership to get it in again and they then found the throttle body was bad and had to be replaced, at this time it now cast me over $500.00 dollars to fix it.
Tl* the contact owns a 2010 mercury mariner. The contact stated while driving 70 MPH the vehicle suddenly stalled. The check engine warning light illuminated and the contact was able to drive onto the emergency lane. The contact shut the vehicle off and was able to restart it. The contact took the vehicle to the dealer who stated the throttle was defective. The dealer replaced the throttle. The failure mileage was 68,000.
Driving to work at steady speed when all of a sudden the car lost acceleration. While I was able to steer to the side of the road, had I been in the middle of a turn or an entry on the highway, it could have resulted in an accident. Pulled over to side of the road. Turned off vehicle and restarted. Drove about 1/3 mile and it did it again. This time when I put the car in park and kept it running it felt like it was trying to jump out of gear and accelerate which was very scary. We determined by calling internet it was the throttle body. Called three ford dealerships where they were all sold out and back-ordered. We found one at the fourth and put it on ourself in 30 minutes. Cost $180 p/n ds7z9e926d.ford needs to do the right thing and recall the affected vehicles as they know it's a problem. They have multiple cars getting this problem fixed daily!!!!!!!
Tl* the contact owns a 2010 mercury mariner. The contact stated that the vehicle stalled without warning. The vehicle was towed to the dealer where a diagnostic was performed, which located the failure at the throttle body. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure and mileage was 88,000. Updated 10/17/13*cn the vehicle was repaired on sept 6, 2013
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 to work when the wrench light came on and the car started to buck. Then the engine light came on and the car slowed down to 0 when I stepped on the gas pedal. Had to pull over quickly as I was in traffic and shut the car off. Started it up again and only the check engine light was on - car would only go about 15 MPH. Found out it was a common problem being looked at by the federal safety agency. Power train throttle body had to be replaced. Not covered under warranty. I am not a happy camper it was not cheap to fix. Eec test code p2111 I found this on the web and was surprised to find out it has been happening since the model year 2009. Shame on ford.
Vehicle stalled 3 times and had no throttle response. Turn key off and restart vehicle to regain throttle response. Wrench light and engine light came on. Mechanic retrieved memory codes p2111 and p2112. *tr performed electronic throttle body test with ids. Throttle body failed and has a fault. Mechanic replaced throttle body
While driving on several occasions the vehicle unexpectedly stalls with no prior warning. The third time I was traveling at approximately 60 MPH on the parkway. I have a second 2010 mariner which had exactly the same problem in august 2013. Both were repaired by the dealer by replacing a defective throttle body.
While driving on three separate occasions the vehicle unexpectedly stalls with no prior warning. The third time I was traveling at approximately 60 MPH on the parkway. A dangerous condition to say the least. I have a second 2010 mariner which had exactly the same problem in january 2013. Both were repaired by the dealer by replacing a defective throttle body.
Very dangerous throttle body malfunction: as I was accelerating from approximately 35 MPH I pressed the gas and suddenly there was no power...nothing. I had power steering and brakes but the car slowed down rapidly and went into what I later found out was safe mode. It was idling rough and the car was slowing down rapidly because I was on a slight incline. A wrench appeared on the dashboard. This happened four more time in three days. The throttle body was replaced. This was extremely dangerous because where this occured the speed limit was 55 MPH, I do a lot of highway driving and I was very lucky this did not happen on the expressway. No code appeared on the diagnostic code reader even though this occured four more times.
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 it's 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
Lost power while making a left turn vehicle stalled restarted but continued to stall towed to repair shop replaced the throttle body assembly.
Suddenly lost all power. Car did not stall but had no throttle. There was no shoulder on busy route 46 in new jersey. I was fortunate to be able to coast into a wendy's parking lot to avoid a collision from the rear. Emergency repair was performed by a local mechanic. Identified fault code as p2112. Car restarted and I was forced by personal circumstance to drive the car home despite the incident. Very scary since I traveled on nj turnpike by newark airport...elevated highway, 3 lanes, no shoulder, 65mph, 18 wheelers. If car had stalled there, I would have been killed!!!! I want my government to take action to force ford to do the right thing and force a safety recall for the throttle body assembly..
