Accelerator Stuck problems of the 2006 Kia Motor Sedona

When driving 2006 kia Sedona van, gas pedal sticks inside the rubber mat causing the vehicle to accelerate. Rubber mats were purchased from kia. Rubber mat comes off the floor post which causes the mat to slip forward. I am concerned for the safety of myself and family. Occurs every time adjustable pedals are positioned farthest to the floor when husband drives the vehicle because he is tall. Kia dealer offered to put a screw in the mat but that was not satisfactory to me as this vehicle was purchased new and the "screw" does not seem to be a permanent fix to this problem. This does not occur with the cloth mats because they are thinner. But the rubber mats are thicker and post is too short which caused the mat to slip off.

First noticeable incident while driving this vehicle in June 2009, while I was driving this vehicle, I pulled out of the driveway, the vehicle all of a sudden stalled, engine light came on and I pushed the accelerator all the way to the floor, nothing. I pulled over put the vehicle in park, killed the engine, restarted the engine, same thing. I had to coast back to my residence. I waited a few hours, went straight out to the vehicle, it started right up and I drove away. The next incident was approx. Months later, same scenario. Now the accelerator sticks, the engine light comes on and the engine revs. I contacted the kia dealer here in tucson, az, they informed me of no recalls on this hazard. I am extremely concerned due for the safety of myself, my family and others this might effect on any road way, something must be done!! I have investigated this online, and apparently this same issue has occurred with several other owners! please help, I loved my kia Sedona, and still owe a lot of money on it<s>.
