Notes: Ford significantly updated the Fusion for the 2010 model year. We wish they hadn't

Throttle body issues have led to a ton of reports about a sudden deceleration and loss of power while driving. Ford issued a “customer satisfaction program” in March 2014 that, unsurprisingly, has left very few customers satisfied.

2010 is also the year we started seeing complaints about the power steering failing. Throttle and steering failure? Yeah, that’s why this is a clunker.

  • Automatic transmission
  • 13,000 miles


The contact owns a 2010 Ford Fusion. The contact stated that while driving 65 mph with the cruise control engaged down hill it would not adjust the speed; yet, the rpms increased to 4000 while the engine made a high pitch screaming noise. The vehicle was taken to the dealer to have the software repaired; however, it would not solve the problem. The manufacturer was contacted and stated that it must be a characteristic of the vehicle and they don't know how to repair the failure. The failure and current mileages were 13,000. Updated 10/21/10. The consumer stated instead of slowing the engine down to maintain speed when going down a steep grade, it revs really high. A service technician stated there was definitely something wrong, but there was no fix for it. Updated 10/26/10

I was driving a Ford Fusion that I had rented from hertz in minot, North Dakota. I was pulling out of the parking space and luckily had my foot on the brake when the car suddenly accelerated. I had to push down very hard on the brake pedal to keep the car under control. I immediately put the car in "park" and the acceleration slowed down. I drove the car that day but reported the incident to hertz and urged them to get the car checked. The Ford Fusion had less than 3000 miles on the odometer so I assume that it was a 2010 model.

Several weeks before the incident, I removed the driver's side all-weather floor mat (the factory-developed optional one) from our 2010 Ford Fusion hybrid and tossed it in the trunk. In the days leading up to this incident, the car had been to the body shop and the car wash. As near as I can tell an attendant at one of those places must have discovered the mat in the trunk and "helpfully" reinstalled it. But I didn't notice this right away. When commuting to work on April 16th, I pressed the accelerator to the floor as I moved into a much faster traffic lane. Upon completion of this maneuver I eased up on the gas, but the pedal stayed down and the car kept accelerating, unintentionally at this point. At first I wasn't sure what was going on, but after about 3 or 4 seconds I heard a "click", the pedal returned to normal and the car slowed. It was then that I thought of the all-weather floor mat, and when traffic cleared I tried another experimental full-throttle dab to see if I was correct. It happened again (but I was ready for it), with the pedal releasing on its own after a few seconds, just like before. At this point I was careful not to disturb the mat's position so I could take video of the problem once I arrived at work. Once in the garage, and with the engine off, I was able to replicate the floor mat-throttle interference on-camera. As before, the pedal stayed stuck for about 3 seconds after I pressed it to the floor. I was able to repeat this several times. But in one trial the stuck throttle persisted for over 30 seconds, with the pedal staying stuck despite vigorous stamping in an effort to free it. The only way it came loose was by lifting my heel which, in the normal driving posture, had apparently been pinning the mat down and making it less flexible. With the heel pressure removed, the mat bent up out of the way and the pedal began a slow return. A you tube video link is available upon request.

I bought a 2010 Ford Fusion from shaefer Ford in cumberland md on 3/17/10. On 4/15/10 I was driving on 220 South from my home in bedford to cumberland. I passed a truck and then tried to slow down and the accelerator would not respond to the brake pressure. For over 1 mile I had brake all the way to the floor and the vehicle was still going at 45 mph. I saw 4-5 cars stopped in front of me so I turned off the car and was able to steer to the shoulder and the truck passed me. I called shaeffer Ford and was towed to their lot. I left the car and later that day I was told that the floor pad had hooked onto the accelerator so that it did not decelerate. They said they check everything and that everything was ok and the brakes were not damaged. I drove the car home that afternoon.

I was pulled into a parking spot in the parking lot of my gym, and the car was close to stopping, or stopped. The car accelerated, and I hit the building. When the crash was over, I looked down and my car's gear was in park. Either the car was already in park, and my foot was still on the brake, or my foot was on the break, and as the car accelerated forward, my hand hit the gear, putting it in park. I have pictures demonstrating skid marks (showing the brakes were engaged). The car is a hybrid model.

Fusion 4-cyl

  • 11,300 miles
Ford Fusion 2010 S - when the brake was depressed the car accelerated until I depressed a second time much harder. The consumer first began to notice the vehicle would intermittently not start in August. He took the vehicle to the dealer, but they were unable to duplicate the problem. The consumer insisted there was a problem and eventually, they found a technical service bulletin that addressed the issue. The problem was attributed to radio frequency intermittently corrupting the crankshaft position sensor and a new ground strip was installed. The problem seemed to be rectified. The weather stripping surrounding the rear window was loose, there was loose metal around the passenger rear wheel.
