Automatic Transmission problems of the 2007 Kia Motor Sedona

Vehicle would not move, went from speed of 70 on highway to not going at all. Mash accelerator and vehicle would not go. Bought got hit in the rear by oncoming vehicles. Could not even accelerate car enough to get to the side of the road. Called kia dealership and they said it is throttle body wire and car is out of warranty. After researching on internet there have been lots of problems with this same thing. Kia said if it happens again just cut car off and back on. Easy said when you are driving down the highway.

2007 kia Sedona (same as Hyundai entourage). One minute after parking the vehicle, it rolled backwards and crashed into a light pole across the street. I did not notice any warning lights or hear any noises before the failure occurred. My wife sustained injuries from trying to stop it, including having her foot run over and a huge bruise on her hip.
