Check Engine Light On problems of the 2005 Hyundai Santa Fe

I was driving to work and my 2005 Hyundai Santa Fe started to "jump" persay. It jumped from 1 rpm to 5 rpm, when I tried ro brake it acted as if my gears were grinding, and it thrusted me forward. This is a very scary incident that has happened alot, but up til this morning, there was no check engine lights on. The check engine light came on so my husband disconnected my battery in hopes it would reset. After about thirty minutes we hooked the battery back up and took it for a drive, and the same thing happened. I almost crashed this morning on the way to work while I was doing 55mph I came to a curve and my car jumped to 5 rpms and I almost lost control of my car. . . . This car is dangerous, something has to be done!!!.

The contact complained about several problems. The first problem was the traction control, which allowed the front wheels to slip in the snow. The electronic accelerator cut in and out when the traction control was on. The dealer was contacted, and they suggested turning the traction control off. The contact tried the dealer's suggestion. And now, only one wheel will turn in the snow, the engine idled low, and the vehicle did not move forward. The second problem occurred on normal road conditions the vehicle lurched forward after a complete stop. The last problem was the check engine light which intermittently illuminated. The dealer replaced the dps valve sensor and reprogrammed the computer software. The contact had only driven the vehicle once since the repairs were completed, and did not notice any difference in the performance of the vehicle.
