Mercury Milan misfire problems

Filed May 7, 2019 · Steering · 116,000 miles · KY

My power steering assist warning and advance trac system fault warning came on randomly for months. When they would, I'd lose power steering, but could turn the car off and on and it would reset and work fine. During those months I took it into the dealer numerous times, but nothing could be found so they would clear the codes and told me repeatedly it was a sensor misfire. I had read reviews of numerous 2010 models having the same issues but never being recalled. Last week my power steering assist fault light came on and I lost power steering completely. I was able to get it into a new auto repair place who diagnosed the entire electric power steering system as having malfunctioned and had to replace the rack and pinion, costing me over $2000. The 2011-2013 models were recalled for this exact reason. The 2010 should be as well. If I had been on backroads driving for my job, which I often am, when this had gone out, this could have been a real safety issue.

2010 mercury milan with 3.0 liter v-6 build date march 2010. Car went into limited limp mode while it was being driven at less than 30 MPH. This has happened on three occasions. Each time the engine drops to a rough idle at 500 to 900 RPM and the "wrench" light is illuminated. Engine does not respond to throttle input. Car speed drops drastically but steering and brakes appear to operate normally. (engine is still running an close to normal idle speeds.) engine does not produce enough power to go up the slightest of inclines. After restarting, the engine the condition clears and car drives normally. Portable obdii scan tools do not indicate any dtc codes. Dealer replaced throttle body mechanism due to an intermittent short in the position sensing circuit. Dealer kept old unit due to core charge. This is a safety concern in that under many traffic conditions the car may be hit from behind or unable to move to a safe shoulder out of the traffic flow.

2007 mercury milan came to a complete stop on a 2 lane highway, at a speed of approximately 55 MPH in the left hand lane with heavy traffic, no indication of problem to try and even pull over. Towed to garage, was unable to fix. They towed it to a ford dealership, coils, spark plugs, throttle body and PCM replaced, still would not run. Towed back to original garage. Did a smoke test on catalytic converter and stated 1 has to be replaced (will not pass inspection) but because of the number of "misfires" they strongly recommend replacing all three. After some searching I have found that this is a problem that ford has not only known about, but stated that they were cooperating fully with the government, however , there was never a recall. I have placed a complaint with the federal safety agency. I requested a quote to trade the car in, but because of it's present situation they offered me $3400.00, kelly blue book value is $7000.00, I still owe $3700.00 on this vehicle, still have to have catalytic converters replaced and just hope that it runs, and do not even at this time know the amount of repairs this far. I contacted ford headquarter and they response was first to have it towed again to the ford dealer. But when I questioned why I would need to pay yet another towing fee, she abruptly stated . "there is nothing we can do because you didn't have it initially diagnosed by ford. This car poses a potential life and death situation for the consumer.

Upon putting vehicle in reverse the throttle increased on its own reaching nearly 6k rpms, by quickly placing the shift lever in neutral and applying the brake I was able to avoid a collision. Restarted the car engine light was on as well as the maintenance light, after checking for codes 2110 was present, cylinder 3 had misfired. Drove the car home it was fine. Drove the car for a week with 2 more of the same incidents (increased acceleration with out pushing the pedal) while driving. On 10/14/13 while at a stop light the car increased the throttle on its own to 6k rpms and upon release of the brake my tires broke loose and began to squeal again I was able to control the car by shifting in to neutral and the rpms settled at 600, I shifted back into drive and it has been fine for 2 days. After little research it seems like this is a common issue (google search) the electronic throttle body is malfunctioning at random mileage ranges and without warning in both the mercury milan and ford fusion. I am highly concerned that a replacement part would not even fix the vehicle. Its not safe to drive and people need to be warned, might be like toyota incident.

Driver was proceeding on I-290 in left lane at speed of 60mph with moderate traffic. The engine started misfiring and bucking without warning and the vehicle experienced a drastic reduction of speed nearly causing accident from behind since the speed reduction was without warning. The wrench light illuminated. The engine continued to decelerate and created a situation where driver could not change lanes to right and was forced to move to left shoulder. The engine completely stalled and shut off before car stopped. After 30 minutes, vehicle started and operation resumed. Service department denied any problem with vehicle. 3 weeks later, while traveling 55 MPH on ny rte 33, the vehicle stalled again at highway speed. The engine could be restarted but only operated with very rough condition. This vehicle is unfit and unsafe to be operated on a public highway.

7i bought my car with around 20,000 miles on it and experienced jerking, rough idling, and a complete loss of power when driving. I returned it to the dealership a total of 3 times for this issue. I was told it was a transmission issue and they were resetting something that had to do with the computer in the transmission. After the first instance of the car stalling, I googled any issues with my particular vehicle and came upon a throttle body problem. I mentioned this to the dealership on several occasions and was told that this was not a common issue, nor was it the problem with my vehicle. Last week, I was driving to work, my car completely stalled while going 75mph on a 4 lane highway. I was almost rear ended by the semi that was behind me as my car's speed suddenly, and without warning, dropped by over 15mph. I made my way to the right side and slowly coasted up an off ramp to get off the highway (as there was no shoulder). Even if you press the gas, nothing happens. You do not accelerate at all. I turned the car off and restarted it. I drove maybe 5 minutes and it stalled again. I had to restart my car a total of 5 times on the 7 mile drive to work that day and was almost hit by other cars just about every time. I called my personal mechanic and had it towed to him instead of the dealership because I was told that this was a different issue than my previous 3 visits to the dealership and ford would not be covering it under my warranty. The mechanic replaced the throttle body and my car runs perfectly now. He said when he called around to get a part he had a horrible time even finding one because they are on back order due to this being such a huge issue across the country. I've been telling the dealership for 25,000 miles and almost 2 years this was what was wrong with my car and now its suddenly not covered under my warranty.

I was driving to work when my 2010 mercury milan lost power. First the engine began missing and running rough, and then the engine stalled and the RPM dropped to idle speed (idling rough). The engine would not respond to the accelerator pedal. No throttle was present. The engine continued to idle (but it was a rough idle). The wrench light on the dashboard came on. I steered the car to the shoulder and turned the ignition off. After waiting a minute or so, I restarted the engine, and it started almost normally (it took a few more cranks of the starting motor for the engine to start). Then I drove to work and aside for seeming to miss from time to time, the engine ran normally. There was no wrench light visible on the dashboard. However, that afternoon, on the way home from work, the problem happened again as described above. The engine seemed to be running normally, then started missing, and stalled. The 'wrench light' came on. I pulled off the road, turned the engine off, waited a few minutes, and then re-started the engine. There was no 'wrench light' and the engine appeared to run normally. This series of events happened three more times before I was able to get the car home and park it in the driveway. This issue happened on july 9, 2013. I took the car to the dealership and was told that the electronic throttle body had malfunctioned and needed to be replaced. Losing power as described above while driving in traffic is extremely dangerous.

While driving on the highway 60 MPH without warning the wrench light illuminated and the vehicle lost power. I had no engine control. Was able to shift into neutral and pull over safely onto the shoulder without being rear ended. Engine exhibited rough idle approximately 800 to 900 RPM. The car was in a limp mode.the gas pedal had no effect. Turned the ignition off and restarted the vehicle wrench light turned off and was able to drive the vehicle normally for 5 miles before the wrench light illuminated and the vehicle lost power. I was able to drive the car home. Connected a scan tool to the obd and no codes were present. The following day driving with the scan tool connected at 40 MPH the same symptoms occurred. The scan tool registered code p2111 throttle actuator control system stuck open. Fortunately I was able to pull safely. Mentioned the issue to the local lincoln dealer and was told this is a common problem with this vehicle and the throttle body assembly needs to be replaced. Was told that the part in on national back order and is not available. This is not acceptable. The problem occurred 6 times within a 10 day period. This car is not safe to drive. The vehicle should be recalled without hesitation and the safety issue resolved.

I had stopped at lights and after accelerating up to apprx 45mph the car become unresponsive when pushing on gas. My first thought was my transmission had went out. I coast over to the shoulder and then the car begin to vibrate and run rough so I shut car down. The "wrench " light came on. I had car towed in and after 3 days and the dealership talking to ford it was decided it was going into the "limp" mode. The fix was a new throttle body. The throttle body part was backed ordered. Per the dealership there was a change on the throttle bodt part due to issues and was back ordered. Parts took about 2 weeks to get and car was repaired and I have been driving for 2 weeks with no issue. I do understand that the car has 80000 miles on it but I seen on the internet where the circuit board and this throttle body had been a on going complaint.
