Transmission Not Go Into Gear problems of the 2005 Suzuki Forenza

I went on a trip to el paso,texas with my family and on my way back I had the worst trouble with my car. My car started jerking a bit. I though nothing of it and kept going just hoping to get home with my kids. On my way back home I stopped by a mechanic shop and they informed it was the sensors in the transmission that were no good. But it is a newer car so I though they must be wrong. I did make it safely to my home. It stopped doing the jerking. Then a few days later it started back up. This issue has been an ongoing since March 4,2008. I thought it was only me but I have found out by autozone that a few people have taken their car fro the same issue. So I believe this issue should b repaired because I did not do anything. I was taken my children 2 days ago to the doctor and what seemed like a normal trip became a nightmare. The car would not go(put yourself in my place at the 5:00 p. M. Traffic) the engine just reved very high and I put my foot down all the way to the floor and then it went forward with a jerking motion forward. I was so scared and still am that I don't want to drive my vehicle because I do not know when it is going to try to stall on me and not shift gears. I just bought the car not even 7 months ago from the dealership. It is over the 36,000 miles and I do expect for this issue to get resolved and for you as a company fix the issue. I did research and I do see all the complaints on this model of car. Are you expecting a major accident for you to take care of the issue?? I do not want to drive in an unsafe vehicle with my two small children! would you? I do not want to get into an accident in order fro you to take care of the issue. The cars keeps jerking and you have to put your whole foot to the floor in order fro it to shift I need results!!!!.
