I had a history of recurring problems with my 2009 Fusion. The battery died over and over again, causing me to finally replace it. The car constantly threw errors regarding low tire pressure. But the largest problem happened when we were driving down a two-lane highway at roughly 55 MPH and the steering wheel suddenly became unresponsive and locked, causing us to hit first the concrete divider on one side of the highway and ricochet across and hit the metal safety rail on the other side. The car was unresponsive to braking. The car hit head-on both times and was completely totaled. I remember frantically trying to open the doors because I was sure was about to explode. This is an incredibly frightening experience for me because there was literally nothing we could have done to prevent it. We weren't speeding. There was no inclement weather. …
I had exited the highway & was stopped at a stoplight in the right hand turn lane. Cars were behind me. When it was my turn to go, the car would not accelerate for me to make the turn. The traction light, wrench light, and engine light came on. I pressed down on the accelerator to try to move the car out of the middle of the 4-lane intersection, but it moved at a snail's pace maybe 4 feet from the turn lane. The car did not have the power to turn or even make it to the side of the road. My car was perpendicular to the cars in the 4 other lanes. I'm thankful I wasn't hit. I turned off the car and restarted it, but the same lights came on, the car was shaky, and could not accelerate. The police pulled behind me and she called the tow truck. The tow truck took us to the Ford dealership. …

Our 2009 Ford Fusion sometimes does not respond when the gas pedal is pressed...then the car quickly leaps forward and accelerates. I presume it May be a problematic throttle positioning sensor / throttle assembly unit. I've done some reading on this...it appears this is a known problem.?...is there a recall...any recourse we could pursue to get this repair done for "free" per se? Thank you [redacted]
NHTSA investigations
Accel Pedal Interference - Acc Floormat
Unsecured mats may interfere with accelerator pedal return to idle. A heel blocker in the floor pan provides a platform that may lift an unsecured mat into contact with the pedal. Ford introduced new pedals as a running change early in model year (MY) 2010 vehicles. Analysis of complaints received by ODI and Ford show elevated rates of pedal entrapment incidents in MY 2008 through early 2010 production vehicles.
