general problems of the 2010 Mercury Mariner - part 1

When intering to tunnel my car suddenly speed up it felt like I had the gas pedle down to the floor. Even while holding the brake all the way down, this did not slow the car down much. There were no warning lights or check engine lights on then or now.

Electronic throttle body p2119 code. All of the sudden losses power going into or out of traffic and the wrench tool light "lights up" it may go away by itself or not , "cut be scary" at times it has shut down in several instances on my own st or down the Ave or another town etc. . . For no apparent reason it happens while turning or during acceleration at one point I had to wait for several minutes on the highway before starting the vehicle again and I get similar codes related to tbs powertrain and the fuel cap I noticed that when filling up, I need to stop pumping gas once it has stops automatically, without me topping it off not even once! and the light will most likely will not come on,it may go away by itself if not I erase the code. I clean the electronic throttle body last summer and it has run with no problems at all until now! well a month a go! this summer I am getting lots of problems with the tbs again same symptoms like before all over again,except for the gas light. Thank you.

Vehicle surges wildly at idle speeds in traffic. Vehicle stalls out while driving regular highway speed, surges wildly while driving, rpm spikes drastically while driving and at idle. Stalls and surges both while entering traffic from a stopped position and while driving at regular pace. Struggles to crank after fueling the vehicle. Spits and sputter and shakes while at idle.

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.

Driving from columbus to cincinnati around 1:00 am with my daughter, son and 15 month old granddaughter. The car lost all power leaving us stranded on the side of the road. As I pulled over the car began to shake, almost like there was water in the gas line. I turned the car off, waited a few minutes and then restarted. The car reset itself and luckily we made it the rest of the way home. Not too long after that, I was driving home from work and it did the same thing. Except this time, it would only go about 2 miles before it would quit again. This is a very dangerous issue. No only could I have been in an accident, but being stranded on the side of the expressway in the middle of the night with an infant was terrifying! I had the throttle valve sensor replaced and there has not been any additional instances of power failure.

I had two separate occasions of my car stalling in the past three days. On may 1st I was traveling at about 40 mph when my wrench light came on and the car stalled out. Fortunately there was a median right by me and I was able to hurry up and move over before the car came to a complete stop. On may 3rd I was traveling at about 35 mph when the wrench light came on and my car stalled out in middle of the road. This time I was stuck in middle of the road but no one was behind me. I was able to restart the car and continue driving. If this had happened on the main road then there would have been a good chance of an accident occurring and harming me or my children.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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!!!!!!!.

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!.

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!!!.

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. .

The contact owns a 2010 Mercury Mariner. The contact stated that while driving various speeds, the vehicle failed to respond to acceleration attempts as the mil warning light illuminated. The contact also mentioned that the failure recurred intermittently. The vehicle was not repaired. The manufacturer was not contacted about the failure. The failure mileage was 100,595.

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.

As I was driving about 40 mph my Mariner jerked then lost acceleration. I was able to pull off the roadway safely into a parking lot. After shutting the vehicle off and restarting it I was able to drive a few feet before it happened again. Again shut engine off and restarted. A few days later it happened again and I took it to the dealer who said it was the throttle body and it is on national back order but it is safe to continue driving to vehicle!! as I was driving home a few nights ago this happened again 4 times within 1 mile. Needless to say I will not be driving my vehicle until this is repaired. (and who know how long that will be!). Please recall this part before someone gets seriously hurt or killed!.

I was driving down a busy highway when my car jerked and then stalled. The accelerator would not work. I was able to pull over and turn the car off. The car restarted and accelerated normally. This occurred three more times. I took the car to the dealership and they said the part was on national backorder and sent me home (in the unsafe car). I now am waiting to hear about when they can get the part.

I was driving along at 45 mph and the vehicle lost all engine power, but did not die. I stopped the vehicle and shut off the engine. I resterted the vehicle and it started fine. I drove two miles and engine lost power again. This time the check engine light came on. I shut the vehicle off and resterted. Check engine light was still on, but I was able to drive one mile to a friends house. I let it sit for 4 hours and drove 1/10 of a mile and engine lost power again. My friend gave me a ride home as I was 12 miles from home. I called a towing service and had vehicle towed to local garage. Computer code registered a p2111. I contacted local Ford dealership and they recommended a throttle body cleaning because vehicle was out of warranty by 6,000 miles. Had service performed on 6/24. On 6/29 the engine stalled again.

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!.

The contact owns a 2010 Mercury Mariner. The contact stated while driving various speeds the accelerator pedal was engaged without any response. The vehicle was maneuvered to the side of the road where the engine was turned off. Upon restarting the vehicle, it resumed normally. The failure recurred at least four to five times a day. The vehicle was taken to an authorized dealer where the throttle body was replaced. The manufacturer was not notified of the failure. The approximate failure mileage was 72,000.

Was driving on interstate highway and accelerator speed dropped to a crawl. Pulled over and saw the wrench symbol. Got the manual out and it said throttle body/powertrain issue. Waited and restarted only 2 miles down the road again and that same thing happened. Car was still running but just going abt 2 mph if that. Very dangerous situation!.

Had test done and was told throttle body is bad. Can not get part in because its on back order.

The contact owns a 2010 Mercury Mariner. The contact stated that while traveling 40 mph, the vehicle suddenly decelerated and would not go more than 2 mph. The contact took the vehicle to the dealer and it was determined that the throttle body had failed. The vehicle was not repaired. The failure and current mileages were 60,000.

Driving 45 mph when the car lost the ability to accelerate and maintain current speed. The yellow solid wrench light came on, the engine remained running, and the car coasted to a stop. The driver turned off the car waited a couple minutes then restarted and car operated normally. This problem happen four additional times and was diagnosed at a Ford certified dealership as having a defective throttle body. Throttle body was replaced and car operated normally for now. Every occurrence was a potentially dangerous situation as I was in traffic.
