NHTSA Complaint #11475206 — 2003 FORD TAURUS

At times the vehicle accelerates by itself albeit I am not touching the gas pedal. While driving the vehicle at 45 mph, I take my foot off of the accelerator and the vehicle maintains the 45 mph speed or increases speed if I am driving down a hill or any downward gradient regardless of the angle of decent. When I try to stop the vehicle using the foot brake it continues to maintain speed and if I put the shift lever in neutral, while trying to stop, the RPM's increase from approximately 1500 rpm's to 3200 rpm's until the vehicle comes to a complete stop, and then, only after approximately five seconds do the RPM's begin to drop to 1000 rpm's. If I am driving the vehicle with cruise control and cancel the cruise control, the vehicle maintains the cruise control speed indefinitely, literally for miles thereafter. I wanted to give this vehicle to my daughter who has multiple sclerosis but it's too dangerous for her to drive with this acceleration problem. Do you have any recommendations for me???
