At about 60mph in a passing lane going up a fairly steep hill, I pressed the accelerator to downshift while passing. The accelerator pedal pulled away from my foot toward the floor. The car began uncontrollably accelerating. I was able to override this with the brakes, but each time I took my foot off the brake the car again downshifted and accelerated maximally. This was repeated at least five times. Shifting into neutral resulted in a high revving engine on three occasions. Turning cruise control on and off or canceling had no effect. I was able to stay on the brakes and get off the highway. I then shifted into neutral and the engine started over revving. I then turned off the ignition and restarted the car, which to this point is behaving normally. The floor mat was not interfering with the accelerator. The accelerator distinctly pulled away from my foot and went to the floor. There was no pedal confusion.

I pulled into a gas station at a low speed; there were four pumps in line. At the first one a car was being fueled so I waned to move to the second pump. When I started to brake the car kept moving forward then I was practically standing on the brake but the car kept moving causing me to hit the stationary car. According to the police report her damage was minor; mine was moderate. The officer stated in the report I was inattentive regardless of me telling him twice about the braking and/or acceleration problem. Hyundai sent an "independent" tech after the car was repaired and they said it was not their problem. I requested that company inspection from the first day of the accident; I was informed it would take 4 to 6 weeks. This is a safety issue; my foot was firmly on the brake that morning.
