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 along normally when the car lurched and the engine went to idle. I pulled onto a lot and stopped the engine while I looked up what the wrench light meant. When I restarted the car it sounded normal, but when I got back on the road and attempted to accelerate it did the same thing. I pulled off the road again and stopped the engine again for a short time. Upon restarting I pulled back onto the road and could accelerate to about 20 mph without any problems. I then limped the car to the dealer, about 2 - 3 miles away, and left it. The next day the dealer called and advised me that the throttle body would have to be replaced (150 miles out of warranty) and the last one the did took 2 months to obtain. I have read on the internet that there have been 27,000 complaints like this one. Isn't it about time for a recall!

I was driving on the highway and all of a sudden lost throttle. The vehicle went into limp mode. I had to pull over and power cycle the vehicle. This happened 8 times in 40 miles. Each time the wrench indicator would display on the dash. I checked the error codes and there were several occurrences of P2111 and P2112. This happened to a relative driving my vehicle a couple days ago, and my wife a month ago. The issue seems to be happening more frequently.

While driving through road construction on the interstate my Mariner lost power. I had my child in the backseat and was lucky enough to be able to pull over and turn off the engine. The power train light and engine light came on. I started it back up and continued until I could exit off the interstate and continue on the highway, where it happened again. Again, I turned off the engine and got it started back up. This happened one more time before I got it to the mechanic. He said that it was the throttle body and that it was on a national back order. There are 8,000 requests for this part! what will it take for Ford to finally issue a recall on an obviously defective part, a fatality?

The contact owns a 2010 Mercury Mariner. The contact stated that while driving approximately 45 mph, there was a sudden loss of power as the wrench warning icon illuminated. The vehicle was towed to a dealer where it was diagnosed that the electronic throttle body needed to be replaced. The manufacturer was notified of the failure. The vehicle was repaired. The approximate failure mileage was 58,849 and the current mileage was 59,000.

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 my Mariner and turn into a heavy traffic road and my car just went dead once I was in traffic. L was lucky that I wasn't hit from behind me. The car warnings displayed a wrench on the car panel. I took the car to the shop and it required repairs to the throttle control/power train. The car only has about 4600 miles on it. I have researched this problem on the internet and this is a recurring problems. There was no warning of a problem. The car just died in the middle of traffic. This is very dangerous and seem to be a known problem. Does someone have to die before they get this problem is recalled? the problem occurred so quickly that if you are not observant to your panel, you will miss it. And, it you are in an accident when it occurs, you will never see it.

I was driving on the interstate when my gas pedal completely stopped working. The only indicator was the wrench light that came on at the same time the gas pedal stopping functioning. I almost had an accident trying to make my way to a shoulder with no way to accelerate during rush hour traffic. After being at the dealership, it was determined that the throttle body was bad and had to be replaced costing $500.

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 2010 Mercury Mariner suddenly began stalling while driving 45mph on a two lane road. While this was occurring, it also began jerking and would not accelerate! the wrench light then came on. I was finally able to pull off to the side of the road and a tow truck was called for. The jimmy granger Ford dealership stated that the problem is a bad electronic throttle body.

- Shreveport, LA, USA

The car lost all power while I was driving on the interstate at 65 mph. I was able to steer it to the side of the road, and to restart it. The same thing happened in 3 miles and then again in 1 mile. It was okay for the next 3 months. Then I tried to pass a tractor and my car stalled. I got it to the side of the road and was able to limp into a Ford service center where they diagnosed a " throttle body failure". I am waiting on a part back order to get it fixed!

My wife was driving down the street in our Mercury Mariner when it suddenly went from 30 to 0 mph for no reason. Her foot was on the accelerator when it suddenly slowed to a stop, right in the middle of the road. When she tried to drive it again the powertrain alarm was on so we had it towed to the dealer. Ford mechanics found it to be an internal short in the throttle body and replaced it. Unbelievably, we had to pay $342.47, after Ford refused to do the replacement of an integral part of the engine even though the powertrain warranty was still in effect and it was a powertrain alarm. Not only do I believe this repair should have been paid by Ford under the warranty, but I believe we were forced to correct a dangerous defect that should have had a recall, as many others have had this same problems with their Ford products and it is extremely dangerous for a car to come to a sudden halt for no reason.

Sudden loss of power, engine idles but no propulsion, speedometer instantly drops to zero.

The contact owns a 2010 Mercury Mariner. The contact stated that while driving 70 mph, the power train warning light illuminated as the vehicle stalled. The vehicle was able to be coasted to the side of the road and turned off. The contact was then able to restart the vehicle and drove to an authorized dealer where they were unable to duplicate the failure. The vehicle was not repaired. The failure mileage was 35,000 and the current mileage was 43,696.

On Feb 2010, I signed a 3-yr lease on a 2010 Mercury Mariner. On Dec 23, 2011, after 8hrs of driving, on the way to my relatives, the vehicle started jerking. With 22,250 miles on the vehicle, my transmission failed; very harsh engagements, vehicle jerks hard between gears, looses power and pops forward when driving steady speed and when approaching an intersection to stop or turn. Safety concerns due to unknown if power failure will occur when there is oncoming traffic or if vehicle will pop me into oncoming traffic or hit someone ahead of me in traffic. Transmission issue also causes poor gas mileage. On 12/24/11, I took it to a nearby Ford dealership and they have had my truck going on two weeks and they are just repairing the transmission. Since I leased this through Ford motor credit, I contacted them last night in hopes that they will at least pro-rate my lease for the month. To no avail, they said they can't. the dealership said that there is no recall for this problem but it seems like I am not the only one experiencing these issues. What can I do?
