2007 Nissan Altima Sedan 2.5 S 4dr Sedan (2.5L 4cyl CVT)
2007 altima fails to start
 I purchased my car brand new, I have very low kms. 7500 kms. 6 months after the car would not start, they put a new battery in and now another 5 months later the problem returned. The dealership says there is nothing wrong, but I even had to buy a portable booster to carry with me at all times. They refuse to fix the problem and tell me that its my fault that I don't drive it enough, even taking it out for over 20 minutes on the highway the car will not start the next day. I have had two other mechanics tell me that is is an electrical problem and to keep on taking it back to nissan to have it fixed. they will not do anything further, even though the warranty has over 1 more year.. not happy
