Not Happy!
 I bought a 2004 Nissan Altima in June of 2005. September of '05 the fuel pump went out on it and was supposedly fixed and covered under my warranty. My car had to be towed to the dealership. In May of '06, I had a transmission fluid leak which took 4 trips into the dealership for them to find exactly where the leak was. This was also covered under my warranty. Now, 1 1/2 weeks ago, my car failed to start again. Once the dealership checked it out, they stated it was the crank position sensor. This is not covered by my warranty and it's going to cost us $140. I am so unhappy with Nissan and have called the Nissan customer service to request they pay for the problem, they won't return my calls.
