2010 Mercury Milan: adaptive cruise control problems

Filed Oct 28, 2020 · Acceleration · 122,234 miles · MO

While driving on a straight flat highway at 55 MPH the throttle suddenly revved up and remained revved up as I removed foot from gas pedal visually checked that it was in drive and that the cruise control wasn't on, and it was in drive and cruise was t turned on. I tapped the gas pedal, then tapped 3 quick times, tapped the brake pedal and about 2-3 seconds after I tapped the brake pedal it quit revving up and it went back to normal, decelerated because I didn't have my foot on either pedal. I continued to drive it and haven't had any other problems.

At dusk on saturday september14,2013 traveling north bound on 6 lane interstate I-55 in far left lane at 67 MPH with cruise control on the car began to slow RPM returned to idling speed under 800 RPM and was unresponsive to accelerator pressure. The traffic was heavy and I was lucky to be able to move across lanes and reach the shoulder before car had slowed to 5 MPH. The wrench light came on. Shut off the car restarted it and accelerator was responsive began to accelerate to merge back on to highway and again lost power. Shut off car again and accelerating very slowly was able to reach an exit about 1 mile away before car again lost power. Called for a tow back home as vehicle was unsafe. Car taken to dealership september 16th for repair and the throttle body needed to be replaced. I learned on line that this seems to be a common problem with certain ford and mercury products but there has been no recall to fix this defective part which puts the driver and passenger in grave danger when the throttle body malfunctions .luckily I was in a fairly populated area and cell phone service was available. I fear what could have happened if traffic had been even heavier or been in a more remote area. These products should be recalled as they present a serious safety issues for drivers.

I was driving with the cruise control set at 60mph and the car popped and lost speed and the car would barely stay running. I pulled off the road ( during rush hour) and shut the car off. I re-started the car and it ran correctly.

The first incident occurred while traveling on a highway going almost 60 MPH when the cruise control stopped and the car slowed and when you pushed the gas petal it did nothing. We slowed and tried to pull to the side of the road, as the car was almost to a stop it started jerking and sputtering almost dying. We put it in park and turned the engine off. We turned the engine back on and it started just fine then this same thing continued to happen every few miles. Check engine light was on so we took it in to have a computer hooked up to see what was wrong but the check engine light had turned off so they were unsure. The problem seemed to just go away for about a week and then it happened again and we got it in and hooked up to a computer and got the codes which we were informed meant we needed the throttle body replaced and it was a common problem with these cars and to contact a ford dealer. Since this last incident it has happened multiple times causing us to not be able to drive the car even a few blocks without it happening 3-4 times. We are now without a vehicle as it is not only unsafe to drive but very inconvenient to have to stop and go a million times to make a short drive. This is ridiculous and from all I have researched it a huge problem for many owners of these and similar cars! This is dangerous and should be recalled and those with issues should not be responsible for making these repairs!

I was driving to work with the cruise control set at 55mph. The car suddenly lost power and throttle response. There was a wrench warning light lit up on the instrument panel. Had no choice but to pull the car over to the shoulder. I turned off the car and restarted it. The wrench light disappeared and I had throttle response. I drove it 3 more miles down the highway and the car did it again. I pulled to an off ramp and took the car by city streets back home. I later took the car to my fathers shop where they hooked up a handheld 'scanner' to it and was unable to pull the wrench light code. I tooled the car back home and parked it and started driving my truck. I had my mechanic buddy bring his mac tool scanner to my house and we hooked it to the car and he was unable to pull the code. So we drove the car with the scanner hooked up and waited for the car to act up again. It acted up again on the highway. We pulled over and got a code saying the "tac is stuck open". I believe it to be a bad throttle body assembly. I researched this on google.

The first incident occurred when I was driving down the road with the cruise control at about 60 MPH and the car would jerk and then would loose power and the check engine and the wrench light came on. The car would be in idle mode and I would have to stop and turn the car off and wait a few minutes before I try to start it again. The second is incident was basically the same only at a different location. The third I was in town going about 40 MPH when the car jerked again and went into idle mode. The next few time that it happened I had a very hard time getting it started and moving again. Once I did get it started I would only be able to go a couple of blocks before the car would jerk and go into idle mode.

When I was driving to work on sunday, I was going 70 on the interstate (I had my car set on cruise control). Out of nowhere, the wrench light turned on, my car made a very loud noise, and I was unable to accelerate my car. I had to pull over at an exit, and when I came to a complete stop, my car was shaking profusely. I turned my car off, and when I tried to start it, it took it several seconds to actually start. I figured it was just a glitch, so I didn't worry about it. Two days later, I was driving down another road going 45 MPH, and I was driving up a hill (my foot was on the accelerator). The same thing happened again. So I took my car to a ford dealer, and they determined that the throttle body needed to be replaced. Then, they informed me that the specific throttle body that I needed was back-ordered for 6 weeks (isn't that a sign that there needs to be a recall??), and that I would have to continue to drive my car like this until the end of july. After researching the issue, I found that over 27,000 throttle bodies have been replaced (foxnews.com), and that there are many other issues that have come up with my car. I don't feel safe when I am driving, especially because the throttle body "dies" (if that's what the technical term is) without any warning.

While at highway speed using cruise control on a slight upgrade, engine suddenly lost power and returned to idle and wrench warning light illuminated. After stopping, it was noted that engine was still running at idle but there was no throttle control. After ignition was shut off for a few minutes, vehicle was restarted and throttle control was found to be normal. Dealer diagnosed likely problem as throttle body, which would be covered under drivetrain warranty but ford subsequently advised it was not covered. Further, owner was advised part was on indefinite nation-wide back-order with no known availability date but that vehicle was drivable in the meantime with the risk that problem could recur with increasing frequency.

Driving at highway speed limit with cruise on there was a loss of cruise control, no throttle response and the "wrench" light came on. I was able to pull off the highway. Engine was running roughly, turned it off immediately. No cell phone service in the area so I could not get a tow truck. Restarted the car. Operated fine to get home 10 miles. Was taking it to the nearest dealer 30 miles from home when the same thing happened. I'm glad I did not have my children with me during these incidents. After viewing internet videos and reading on many internet sights this seems to be a problem with many mercury milans. Ford needs to recall and fix the problem that causes this.

I was driving down the interstate a couple of weekends ago and all of a sudden my cruise control shut off and I had no throttle response. I pulled over and the engine sputtered very badly. After turning the engine on and off, I made it to my destination. When I was coming back on sunday, this preceded to happen two more times to me. Once when I was in the middle lane of a heavy traffic location. I couldn't accelerate or do anything besides break and avoid an accident, which was very close. I am lucky that no one got hurt but it became very evident that there was something wrong with the throttle in this car. After researching it more, I starting reading some of these same complaints, and the ford mechanic I took it to even said this isn't the first or even the second time he has heard of this failing on the 2010 milan. He claimed that was due to the electronic throttle bottle and believed it was from a defective unit on most units (good to know the problem except it wasn't covered under warranty, not recalled, and cost me $500). After hearing this, there is no way that this can not be recalled and fixed on every milan that has this same unit with the same serial number. I don't know if any accidents have occurred directly from this problem but I was close to one that definitely would have cost some people some lives. I am sure if this is a defective unit it will definitely cause one soon.
