Front Air Bag Sensor Control problems of the 2005 Suzuki Reno

I got my car in may, 2006. It was brand new when I bought it, but it was in the shop only six days after. I began to notice that my car would jerk when it was shifting gears (although it was an automatic). Over about a week's time, it got much worse and I had to bring it in for repairs. I was told that the transmission had not been updated. I brought it back three more times with the same problem. The 4th time I brought it back, it was so bad that not only was it jerking while shifting, but while staying at a steady speed as well. Finally, my check engine light came on because my transmission was bad. At the same time, my passengers side airbag sensor was not working. I would sit in the seat and the light would come on saying "passengers airbag off. " I brought it back more than 4 times for both the airbag and transmission. Sometimes, I would be told they "could not duplicate the concern" and therefore, they could not fix it. Other times, I would be told my car had been updated and fixed and that I should not have any other problems. After only 5 months of owning the car, I had to file a lemon law application. Neither my transmission or my airbag have been fixed, and I am currently driving a car with a bad transmission and no passengers side airbag.
