The throttle is not working right. I was almost in 2 accidents because of this. I step on the gas and nothing happens. I hear that 1000s are having the same problem but no recall. This is very dangerous when in a 75 MPH zone and suddenly no power.

I was driving about 60 miles an hour on an expressway when the throttle control/powertrain indicator light came on and I could no longer accelerate the vehicle. As I pulled over to stop, the vehicle lurched forward multiple times before I was able to shut the engine off.

Wrench light on mercury mariner 2011 with slow (20-40mph max) and rough ride home. Yesterday while leaving work, I turned right out of the parking lot onto the main road. Immediately my mariner hesitated, jerked forward, and a wrench light came on. My SUV slowly accelerated to 20mph and struggled to get to 40mph. It road rough and I wasn't sure if it would stall or not; however, I was able to slowly make it home. I looked up the wrench light and learned I was likely having a throttle body or powertrain problem. I found online that the dealer would fix it, but unfortunately, that was only through january 2015 and had expired (before the dealer even sold me the SUV.) I started the SUV this morning to take to the dealer to get fixed, but the wrench light has gone off and there is not proof to show the dealer of the problem. I am looking into replacing the throttle body at my own cost as a preventive nature. I wish I would have known of this before the dealer sold me the car.

Last year, driving on state highway and vehicle loses power. Wrench light comes on, engine is running, no gas, etc. Shut off, wait, and start again. Light is off and runs ok. This happened several more times. Contacted ford customer assistance and showed there was a customer experience recall on throttle body. Took it to a dealer and they found nothing wrong. I got it back, and problem reoccurred. Took it back to dealer,they drove it around, and couldn't find anything wrong. Finally, in another city, left work and lost power and engine light came on and didn't go off after restart. Contacted dealer and they replaced throttle body sensor (or similar) for free. This last week, was driving on interstate 75mph in traffic and I lose power in passing lane. Luckily coasted to shoulder, restarted and lights off. Happened again this morning going to work on state highway at 60mph. Talked to ford and was told they cannot help me until I have a dealer look at it. Cannot get an appointment until end of next week. Worried about driving this vehicle I've had less than 5 years, but if dealer cannot find error, I have to take my chances and wait until they can get an error.

2011 mercury mariner transmission failed without warning, the computer chips should have given some kind of warning.

I was driving down the highway on my afternoon commute home with my 3 yr old daughter in the back seat and my vehicle lost power and the check engine light and a wrench light came on and it would not go above 25 MPH. I almost got hit in the rear of my vehicle cause I was not expecting this to happen by any means, but I was able to coast off the highway and shut the engine down for a few minutes and restarted it drove about 5 miles and it did it again.

I was driving through my neighborhood on the way home from going out to dinner. I went around a curve and then when I started going up a slight hill, the engine surged. I didn't think to much about it until I lost almost all power. I could not get up to a speed higher than 5 miles per hour. I was able to get within one block of my residence. I waited for about an hour as I looked up the diagnostic code that my odb2 scanner gave me. I found out that it is code p2111, throttle actuator control system - stuck open. I went back to my car, after about an hour, and it started just fine. I was able to drive my SUV to my local ford dealer, with someone in another car following to make sure that I didn't have a repeating issue. I did a night key drop tonight, the same day as when the issue happened. I included the warranty letter that I had received from ford regarding the throttle body replacement. I cannot understand why ford would not issue an official recall to fix this ongoing problem. I feel very fortunate that I was not on a busy interstate highway or otherwise congested road when this happened. Will there have to be numerous reports of fatalities or serious property damage before this issue is actually rectified?

Was on a very busy four-lane road driving approximately 55 miles per hour; it was dark and raining. The car suddenly slowed to almost no movement, but the engine was running. Was able to drift into a lowe's parking lot safely off the highway. The engine light and a wrench symbol appeared; I cut the engine off and waited about 10 minutes and restarted. Vehicle got me to the hotel where I was staying about a 1/2 mile away. Next morning, I had someone follow me so that I could attempt to get it to the ford dealer in princeton, west virginia. Car stalled on 5 occasions; restarted it, go a mile or so and had to restart again. The service department was excellent - they immediately took the car in (I was in town for a funeral); tech discovered it was the throttle body. It was replaced, but at a cost of $594.85. This was the second incidence in less than 4 days with this same problem. On december 2, I took the vehicle to the local ford garage in greeneville, tennessee, where I live. The engine light had come on and I was concerned since the manual said to see the dealer immediately. Local ford garage cleaned out the fuel line and said I should not have any more problems. Engine light was off and I thought the car was okay. Then on december 5, drove to princeton, west virginia, and the nightmare began. It appears that the ford motor company is aware of this problem since so many owners have complained. There should have been a recall and the problem resolved. It is extremely unsafe to be on the interstate or any road where traffic moves fast when your car goes to a basic idle and will not accelerate.

My wife was driving the 2011 mercury mariner on the interstate at 60 MPH when the wrench light (throttle control/powertrain) came on and the car speed dropped rapidly to about 20 MPH. Fortunately she was able to pull the mariner over to the side of the interstate and came to a stop and shut the engine off. When she restarted the mariner the light went away and power to the mariner was restored. This is has happened to the mariner twice.
