My husband was driving the car at 65 MPH on the highway and the care went limp and would not accelerate. He had to pull over to the side and restart the car. This happened to him 3 times and me one time. I took it to a dealership and it is the throttle body. You have received several complaints and there is an ongoing investigation. In addition, the dealership was going to overcharge me for the repair. Please do everything in your power to get ford to recall this party and reimburse the customer before there is a fatality.
2010 Mercury Mariner acceleration complaints
Page 3 of 3: complaints 41 to 66 of 66, newest first, as owners wrote them.
I have no throttle response, engine RPM drop back to an idle, engine runs rough and stalls. No power. Moving to the side of the road, turn engine off and restart and will runs fine, but today this problem recurred every 4 miles. I was only 22 miles from home but that is a lot of stopping along side of the road.
Was driving on freeway at about 70-75 MPH and hesitation occurred and speed uncontrollably decreased. I went to right lane (had been in middle lane) and stopped on the shoulder of the nearest exit lane. Luckily it was very close. I was afraid that I would lose control of steering also. This is 3rd time this happened, so took to dealership and they replaced throttle body assm. For close to $500. Technician said I should be happy now, the new part had been re-designed. I'd be alot happier if ford had taken responsibility earlier when they realized it needed to be redesigned. The previous occurrence I was in left lane at very busy time on xpressway and had to pull onto the left hand shoulder....very close to being hit.
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!
Stalling. After driving 60 miles, some at freeway speeds, we stopped at a crossroad to cross. Upon crossing it ran rough and stalled just as we crossed the street. Waited two minutes, restarted and drove rest of way home with no problem. Posted speed on road we crossed is 55 MPH. Had it stalled in front of traffic there could have been an accident. We had our two grandchildren in the back seat. This is the 2nd time in 5 weeks. Had the fuel pump and spark plugs changed the first time. Ran fine until yesterday. No check engine light is coming on. Today I ordered an throttle body.
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.
I was driving approx. 55mph on the parkway when my vehicle gave me a kick back (shook a little) and began to decelerate until it completely stopped. I could not get the vehicle to accelerate and had to pull over to the side of the road where I turned the vehicle off, turned it back on, and was able to drive again. I drove approx. 3 miles before the problem occurred a second time, this time I was unable to make it all the way to the shoulder before the vehicle completely stopped so I ended up at a dead stop in a turn lane. I was able to get the car to the shop without any issues occurring again and was told the issue was reading as "p2112 throttle actuator control stuck closed" - the entire part needs to be replaced and will cost me $400 as it is not covered under warranty. I called fomoco and was told that they were not aware of this issue despite many complaints I have seen online through the federal safety agency. I am hopeful that ford will come through and pay for a portion (if not all) of this repair as this was an extremely dangerous incident and one that is clearly occurring with many of their vehicles with the drive-by-wire throttle. If ford does not recall this, it is only a matter of time before someone is seriously or fatally injured. I can only imagine if I would have been driving down I-95 at the time my throttle failed.
Tl* 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.
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!
The engine suddenly went from 70 MPH to limp mode at about 900 RPM's or so. I was able to get to the shoulder and turn the engine off. I restarted the engine, and it worked normally allowing me to accelerate and leave the expressway. I was not sure what had happened so I did not think anything of it. This has happened four more times since. I thought at first that I had bad gasoline because the engine light went on for the second incident and the car was low on gas. I limped to a gas station that time and filled the tank. After restarting the car everything worked normally, and the engine light turned off. In the subsequent incidents, I did not notice the engine light going on. I just turn off the engine and restarted the car. This is very dangerous to lose power at 70 miles per hour. In one case I had just past a truck on a two lane highway. I noticed that this seems to fall under your the federal safety agency action #:pe13003.
On multiple occasions I would be driving the car and it would lose all power and the wrench symbol would appear in the instrument panel. I would have to pull over, stop the car and turn it off. It would then start and I could go for an undetermined period of time and it would happen again. This resulted in more than one near miss by other cars traveling on an interstate. I had it repaired by the mercury dealership who had to order the part since they said this was happening so much it was hard to get the throttle body part needed to repair the vehicle.
Tl* the contact owns a 2010 mercury mariner. The contact stated that while driving approximately 30 MPH, the vehicle shook violently and stalled. Also, the contact stated that the wrench warning icon and the check engine warning light were illuminated. The failure recurred intermittently. The vehicle was taken to a dealer where it was diagnosed that the electronic throttle body needed to be replaced. The manufacturer was notified of the failure and stated the parts needed to repair the failure were unavailable. The vehicle was not repaired. The approximate failure and the current mileage was 51,000.
While operating vehicle at about 25 MPH, the vehicle slowed to a limp. It didn't stall. After turning vehicle off and restarting it seemed fine for a few minutes then slowed again. Had vehicle towed to my mechanic. Code p2112 was indicated and a new throttle body was installed and re-programmed.
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.
Car stalled multiple times and went into what the dealership calls limp mode. I was informed I have a bad throttle body and motor asy - [ds7z9e926a], it is my understanding there is a nationwide back ordered on this part. The vehicle is used primarily on the freeway at speeds in excess of 65 miles per hour. It is my understanding there has only been a few hundred complaints. I wish to add one more to the list. I am being told no eta on when ford will get the back order of parts cleared up. 6 ? 8 weeks without my primary vehicle.
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.
The car just died on the motorway and left me in a dangerous situation. The problem is an ineffective throttle body ( code p2111 ).
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.
Tl* 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.
A year ago in july of 2012 not sure the approximate date, I was on my way to work and all of a sudden everything just cut off. I'm in the middle of the road, accelerator to the floor and nothing. I took the car to the dealership same day and they had it all day long and couldn't figure out what caused the short and sent me on my way. Now present day which is a bout a year later I take my car in for a simple safety inspection, wait 10 minutes for the porter to bring me my car to find out its idling and the accelerator is to the floor and its not moving. The gentlemen comes in and tells me its my throttle body going out on the car, he told me this has happened to several people and the part is on back order. He said a guy has had his car sitting there for 10 days and the part has yet to come in. They tell me this needs to be replaced, but ironically enough my warranty expired 4 days ago may 25,2013, which I wasn't aware of. I was at the dealer 2 months prior getting a oil change this didn't dawn on you to tell me it was going to expire. So I came to you with this problem a year ago you had no clue and said have a great day, I've been in every 3 months or so for oil changes since that incident, and you couldn't have noticed this problem before my warranty expired awfully convenient. I'm amazed with all the complaints and problems I've seen about this same issue and no recall has been made. This is dangerous. What it tells me is that ford doesn't care about their consumers enough to take this matter seriously and correct this error.
While I was driving on highway at 70mph - in cruise control, car suddenly starting losing speed. Tried to resume speed but was not able to accelerate, so I pulled over. While stopped, car started acting like it wanted to stall so I shut car off and had it towed to shop. Mechanic states they are getting a throttle body error.
2010 mercury mariner. Consumer writes in regards to vehicle hesitation intermittently at various speeds. *smd the consumer stated she began noticing the problem in 2011, after a 2010 update of the transmission software in a factory recall. In addition to the hesitation when trying to accelerate, there were also a few instances where the cruise control seemed to either surge or back down, as if it didn't know quite how to respond, usually, but not always, when on a slight incline. The consumer stated on one occasion, when the vehicle was in park, with the motor idling, she was unable to get the vehicle to go into to gear on the first attempt, when it did shift, it shifted very hard and noisily into gear on the 2nd attempt. Also, the vehicle would shift rough in lower gears, typically from as top or accelerating after slowing to almost a stop. The consumer went to another dealer, after the dealer where she originally purchased the vehicle from, failed to address the problems she experiencing. The second dealer informed her, the transmission valve body was damaged even before the recall came out in 2012. The part was replaced. However, the consumer experienced a hesitation in january 2013. The consumer stated after reading about an investigation of ford vehicle, which included her model year, she was concerned about the throttle body, which had not been replaced.
This is a letter I wrote to my repair service on 8-3-12. "this has happened three times in the last two days and is a very dangerous vehicle to drive. When driving the vehicle on a side street once and twice on the expressway, the vehicle suddenly loses power and while the engine is running I could not accelerate. The engine light and tool light both came on and twice just the tool light came on (the wrench). Nothing could be done to regain speed. It seemed as though the accelerator pedal was disabled. I had to pull over to the shoulder of the road, turn the engine off and restart the car. If I had not been close to a shoulder, this would have been most dangerous for me and for the traffic behind me. The car just loses all power and getting it to the side of the road and out of the way of traffic is a dangerous endeavor. This car cannot be driven safely. " I drove the car to a close by local repair shop. The same thing happened to a shop employee. The owner of the shop recommended taking the car to a dealer. I am not a timid driver, but I was afraid to drive the car and had it towed ($52.50) to the ford dealership. The cost to replace a throttle body was $516.08. I read recently that the car was reported to supply limp-home speeds. I did not experience this and definitely feel this is a very dangerous problem.
Tl* the contact owns a 2010 mercury mariner. The contact stated that the vehicle stalled twice and without warning. The contact stated that the power train warning light illuminated on the instrument panel after the failure occurred. The contact took the vehicle to the dealer and was told that the throttle body needed to be replaced. The vehicle was not repaired. The failure and the current mielages were 35,500.
