While driving the vehicle a warning came on stating power assist failure. Car had manual steering only. The first time it happened it went away when the car was restarted. No such luck this time, warning stays on and no power steering. Luckily I was on straight roads both times. I see there was a recall on this but the dealership says there is none??

Our car suffered loss of power and erratic throttle (surges of forward movement even when foot not on the throttle) several times in January 2017. Car unsafe to drive, would leave stranded in the middle of high-speed traffic on highway. Diagnosed with a bad electronic throttle body by russel and smith Ford dealer in houston, replaced 1/19/17 under "Ford customer satisfaction program 13N03." On 8/28/17 same symptoms occurred, intermittent power acceleration and loss of acceleration while at speed. Taken to brandon Ford (Florida) that day, again diagnosed with a bad electronic throttle body, which was replaced. Picked car up 8/31, and within 1 hour we lost power while at speed. While at a red light, car surges forward even with brake pedal applied and no foot on the gas. Have again been told it must be a bad throttle body.

As I started the car the drove a short distance then it started to buck then the wrench sign came on the dashboard. I checked the manual and it said throttle/transmission. I switched off the car and started again then a few seconds it happened again. After shutting down for five times I managed to get home safely. No indication whatsoever prior to this happening.

Vehicle lost most engine power. Could only be driven at low speed. Turned ignition off and then re-started. Vehicle then seemed ok until it did it again......and again and again. Took vehicle to dealership where they replaced some valve and gave the car back to us. Car did not make it 2 miles before it exhibited the initial problem. In other words "they fixed nothing for the price of around $500." The vehicle is now going back to the de.... stealership.

- Indianapolis, IN, USA

Vehicle traveling at 55mph and wrench light came on. Vehicle engine did not stall but dropped rpms and would not respond to pressing the accelerator. Vehicle slowed to a crawl onto the shoulder of the highway. After putting car in park and shutting off engine and then starting up again the wrench light went off and the car ran fine. This has happened several times in the past few days even on the interstate with heavy traffic behind me...I have almost been rearended several times while I was trying to get off the road out of traffic!!!

The contact owns a 2011 Mercury Milan. The contact stated that while driving approximately 55 mph, the service warning light illuminated as the vehicle suddenly stalled. The contact stopped the vehicle and turned the engine off. After restarting the engine the vehicle operated normally. The vehicle was diagnosed by an independent mechanic but the defect could not be duplicated. No repairs were performed on the vehicle. The manufacturer was not notified. The failure mileage was 41,000.

- Clinton, NC, USA

The vehicle was running normally but suddenly faltered and entered the "limp home mode" where the engine speed is limited to 900 RPM. I turned off the busy street on to a side road and turned off the engine. Upon restart, the engine ran more or less normally, albeit with the check engine light illuminated, for a few minutes and then entered "limp home mode" again. This happened twice more on a 4 mile drive.

- Lincoln, NE, USA

Driving near 55 mph on local highway and applying pressure to gas pedal to accelerate. Felt and heard a 'clunk'. vehicle immediately lost ability to accelerate with pressure applied to gas pedal. Exited to shoulder. Noticed yellow service (wrench) indicator light was on. Put the car into park and turned off ignition. Re-started vehicle; service indicator light did not come back on. Put the car into drive and re-entered traffic flow. Did not have an incident in another 30 miles of driving. Took the vehicle to dealer for diagnosis. Dealer diagnosed problem as requiring new throttle body. Very dangerous situation.

- Plymouth, MN, USA

Driving on a straight away the vehicle suddenly makes a noise as if it were shifting very hard although it was not. Immediately lost acceleration and dashboard light illuminates. Pulled vehicle to the side of the road and RPM needle bounced as car lunged but would not accelerate. Called for roadside assistance and my dealer's service department who knew based on my description a possible cause. Vehicle towed to dealer, diagnostics proved throttle body needed to be replaced. Repair made. Research proved that this is a known problem but no recall has been made. It was a very foggy morning and several multi car accidents had been reported. Had I been on busier stretch of road at the time of the break down I could have easily been killed with slowing down suddenly and without any evident cause. A recall should be issued and refunds made to those who have already experienced this failure.

I was driving approx 25mph when my vehicle suddently started jerking back and forth, there was no acceleration, and the wrench light came on. I pulled over to the side of the road and turned off the car. When I turned it back on minutes later, it seemed to be back to normal. I proceeded down the road and made it about 3/4 mile when it did it again, this time in the middle of the intersection. I was able to coast through and pull into a parking lot. The dealer towed it in and said it is the engine throttle body. They state the part is on national backorder until November (3 months away!), with 25,000 cars currently waiting for this part. I don't see how there can be this huge of a problem but no recall yet. Ford really needs to take responsibility for this malfunction.

This happened once several weeks ago with my wife operating the car and newborn in the back. I wasn't in the car so I did not witness the problem. Over the past two days I have experienced the problem first hand several times. Car stops accelerating during normal operation. The check engine light comes on, the accelerator stops working and car begins to idle erratically. The engine does not shut off. Once you coast in heavy traffic to the side of the road, you may turn the car off then restart and drive without issue for an indeterminate amount of time (once it was several weeks, once it was ten minutes). The check engine light will be off and no code will be logged into the computer. I took the car to a mechanic ten minute after an incident and the computer picked up nothing wrong with the car. With all these complaints and anecdotal evidence, by this time Ford and the NHTSA must be aware of the problem. Where is the recall?

- Doraville, GA, USA

Two or three times in the last day or two the engine has lost power/died & car would have to be steered to side of road & put in park to be restarted! on at least one of these occasions the car was in traffic at highway speed & could have really been a problem, wife was driving & had grand daughter & great grand daughter in the car with her, from what I can read & find out Ford Motor Co knows of the problem, but has yet not addressed it, it appears to be a problem with a circuit board on the throttle body. This could potentially be a real bad situation! I think some ones attention needs to be directed to this problem! why has this not been a recall before some one really gets hurt?

- Milan, MO, USA

The vehicle stalled while driving at 55 mph. No power to accelerate and had to pull over on hwy. Happened a second time while accelerating at a green light.

- Waconia, MN, USA

I was driving on the interstate when the car suddenly stopped accelerating. A wrench appeared on the dashboard. I had to brake to a stop along the side of the interstate. I restarted the car and it seemed to work fine. This was Wednesday. The same thing happened again on Friday and then again on Monday. At that point I took it to the Ford service center. They had to replace the throttle body, costing me over $430. Additionally, had any of the roads been busier or had no places to pull over, an accident easily could have occurred.

On two occasions on the same day (7/17/13), once at low speed (less than 15 mph) after turning into a parking lot and later the same day at 65 mph on the highway, my 2011 Mercury Milan went into "limp" mode with the wrench light illuminated on the instrument panel. The car lost adequate power other than to essentially coast to rest. Once at rest, it would not move and the engine began to shake violently while idling. Upon restarting the car, the wrench light went off only to come back on again after attempting to move the car. At this point, I had it towed to the nearest Ford dealer's service dept. But they were unable to replicate the issue or definitively diagnose the problem but "suspected" it might be due to throttle body issues (which as I understand is currently under investigation as noted below): Investigation subject : electronic throttle body malfunction date investigation opened: Feb 21, 2013 date investigation closed: Open NHTSA action number: PE13003 component(s): Engine as the local Ford service department was unable to definitively diagnose or replicate the issue during in-shop testing or while road test driving it themselves for 9 miles, they returned the car to me. While I was driving home from the dealership, the issue occurred again (less than 9 miles away).....this time at full highway speed (approx 65 mph). Once again, the car went into "limp mode" with the wrench light illuminated on the instrument panel. Upon re-starting the car, I was able to drive the rest of the way home without any additional issues. While it has not happened again yet (I've only driven to work the following day since all this occurred), this issue is most certainly an unpredictable, serious danger to myself as well as other motorists.

Just driving and engine cuts off due to bad throttle body.

August 2012 - driving approximately 35 mph and the vehicle suddenly jerked and the safe mode light and engine light turned on and I could no longer accelerate. Put car in neutral, then stopped, put it in park. Turned engine off, then waited a couple of minutes and tried again. It started, but after accelerating past 10 mph, it did the same thing. After 3 attempts, the vehicle went back to normal driving condition. The engine light went out on its own. July 2013 - driving on the highway with cruise control set to 64 mph, same thing happened but was quite scary because we were on the highway which was busy and we had to get over to the shoulder and then once we were attempting to accelerate, we had to try to merge with busy traffic. The engine light is on so we were able to have the issue diagnosed and it is a faulty throttle body that needs replaced.

- Omaha, NE, USA

Vehicle lost all power and RPM dropped below 1000, engine would not respond to accelerator depression. The check engine light came on and I had the trouble codes analyzed and it was the throttle body part that was defective. I called the dealership where I purchased the car from and they informed me that particular part was on back order and that they have had numerous vehicles with that problem.

- Talladega, AL, USA

I was sitting at a red stop light, and then the traffic light turned green. I lightly pressed the gas but the car would not go, and all a sudden I looked down and the check engine light is on. I pulled over to the side of the road (while turning hazard lights on), placed car in park, and turned the car off. I turned the car back on (started just fine) and attempted to go again to get to a safer destination (was right in the middle of the intersection). The check engine light remained on and the car would not go any faster than roughly 5 miles per hour. Then the wrench light came on (which apparently means a transmission problem). I pulled the car over again and called for help. Eventually I got the car into a parking lot (meanwhile traveling at about 5 miles per hour and blocking 5 O' clock rush hour traffic). Car had to be towed to nearby shop. They told me the throttle body had quit working (stuck closed) and the car was not getting enough air into the gas for the car to run properly. 400.00$ later, it was fixed. I have had the car for a little over a year and put about 10,000 miles on it since purchase. Ridiculous.
