Nothing so far, after a bit more than one year.
Seems like a good car and good value so far. Keeping my fingers crossed.
I have had my Nissan Altima GXE for three 1\2 years. I have logged over 100,000 miles, been through two accidents, and the car has not had any part of the engine fail. Change the oil, tires, and the ever so often tune up. A great car! Would recommend to anyone, and consider getting another Nissan in the future.
