My transmission is giving me major problems. I took it to have it checked out. As most others have stated, I too, was told there was nothing wrong with it. However, it jerks, shifts hard and erratically, and gets stuck in 5th gear. The only way it will go back to first gear is if I shut the car off and restart it. When it gets stuck in gear, the "check engine" light comes on. I have been told that I will probably will be better off getting a new transmission. But with all of these complaints, there should be a recall on these cars. I don't think it's a mere coincidence that there are as many complaints about the transmission.
I think that if enough of us call the Nissan consumer affairs 800 number, something will be done. It is as follows: 800-647-7261. The web address is www.NHTSA.gov.
