2010 Ford Fusion: sudden unintended acceleration

Filed Nov 21, 2025 · Brakes, Electrical · SC · crash

Unintended acceleration event. Entered vehicle, put my foot on the brake, cranked it, held in that position while seatbelting. Engine had a VERY loud revving sound. Within seconds vehicle moving backwards on its own. Foot still on the brake, had not touched gas pedal, had not touched gear shifter, and was still sitting straight forward with my foot on the brake and confirmed gear shifter in park. The car quickly accelerated backwards faster and brake pedal had no effect on stopping or slowing vehicle. Went approx. 30’ across parking lot and only stopped because we hit truck parked behind us. Quickly turned off engine and removed keys. Shifter still shows Park. Careful driver. No history of accidents. I found there were several thousand reported events of unintended acceleration (Ford vehicles 2002 to 2010). Ford tried to explain many as driver error or floor mat touching the gas pedal. My mat was clipped down, as designed, with no all-weather mat on top of them, and my foot did not leave the brake pedal. AI says revving as described is "classic behavior of failing Electronic Throttle Body on 2010 Fords", "Surging without touching the pedal and known defect are extremely common". Says if "Worn or failing shifter linkage/bushings vibration form high revving could make it slip into Reverse". Ford has a 19S54 recall for AntiLock Brake Systems (not notified), where "A normally closed valve may be stuck open, which may result in extended brake pedal travel". Ford reports on similar vehicles "lunging" was due to deposits in the throttle body. Ford has installed brake override on vehicles after 2010 but that doesn't protect people driving older vehicles. Please look at combo of factors that could cause this. Disappointed to read Ford purged customer acceleration reports prior to hold 5 yrs and an expert they provided at trial was someone sheltered from all research Ford had on this issue so he pushed "driver error" as the case. Clearly not here.

Throttle body being replaced again. In june 2014, as part of the recall, the throttle body was replaced. On may 24, 2016 the car started decelerating and then suddenly accelerating while driving on a city street at about 40 MPH. Then the orange wrench light came on. I went to dealer on may 26, 2016 and they diagnosed the throttle body as defective. Replacement is covered under the 10 year 100,000 mile extended warranty that ford agreed to with the federal safety agency. Now I'm wondering if the throttle body will be a recurring problem and hasn't really been fixed.

I have a 2010 ford fusion sel awd v6 which I purchased about 2 years ago. I have started noticing shifting problems with my car. It first started about 3 weeks ago now. The car acted like it couldn't figure out what gear to go in, while making a left turn through traffic it hesitated a lot & then figured out what gear to get into, barely avoiding an accident. I was then coming back from the airport with my sister & it clammed down in gears as we started to stop & then lunged forward 2 times almost hitting the car in front of me. I have taken it into the shop & they said they needed to reflash the PCM, this was done the day before yesterday. I got it back yesterday & it started doing the exact same things. I have seen that a recall notice was sent out to some people years ago with a time limit on getting this fixed. Recall notice 10b15. It said it ended in april of 2011. Can thr be a time limit on this sort of thing? Some people don't have $1,000's of dollars to fix cars. What can someone do to correct this issue.

I have a 4-year new ford fusion 2010, manual shift transmission. On 12/17/14, while I was driving at approx. 40 MPH on a busy road putting my car on gear 4, all of a sudden, the wrench light lit up, and the car jumped violently as if it was at gear 1 or something. Startled, I gently pushed the gas pedal a bit more, that didn't help; tried again, still violently jump. I hit the clutch, pressed the break pedal just enough to steer my car off the road to a parking lot. After turned off the engine, checked the car, then started the engine again, the wrench wasn't lit, and I drove away. -- this was the first time the trouble occurred. Before the problem re-occurred on 12/20/14, I noticed several sudden accelerations, and sudden stalls while I was driving. The 2nd time the wrench light lit up, same problem: car jump, felt like on gear 1 while actually on gear 3 for a while, have to stop in the middle of the road and re-ignite the engine to get the car moving again. Local ford dealer did diagnosis and concluded the throttle control body was bad, to fix the problem they must replace the throttle control body and charge me $450. They said there is no warranty on the throttle control body, and parts do go bad sometimes. Really, in 4 years? For a well maintained, garaged car at 34k mileage? The problem smells like a defect, not a standard wear and tear, why should I pay for replacing a defect part? How do I know whether the new part is not a defect again? I'm scared of driving on high way.

As I was driving I suddenly lost power and there was no response when I pushed on the gas peddle. The car was shaking and making noises. I was able to continue driving after I put the car in park and removed the key for a few seconds. A few days later this happened a second time. I was driving about 10 miles an hour and the car again lost power and was shaking and making noises. Again I removed the key and waited a few seconds and was able to start the car and drive normally. The third time this happened the car suddenly accelerated and lurched forward. I had the car towed to my mechanic and he said he cleaned the throttle. He could find nothing else wrong.

I run a livery business and luckily there were no clients in the vehicle when the power steering just stopped working. I brought the vehicle directly to my mechanic and hooked it up to the computer, although the service advance trac and power steering service now warning lights are on, his computer is not pulling codes or finding any problems? I then went to the dealership and explained the problem to them and they are saying I am going to have to replace the entire steering rack although I have read there is no guarantee this will actually rectify the problem. When researching this online I am amazed at the amount of complaints I have found. Why has there not been a recall on this yet? Luckily there have been no serious injuries or deaths due to this existing problem. What is it going to take ford to resolve this? Maybe there should be a class action lawsuit filed just like the unintended acceleration lawsuit. I am very disgusted. I am now losing money as I can not run my business with no vehicle.
