 I bought this Maxima brand new. It was my 4th maxima and because I was so impressed with previous models I didn't hesitate to upgrade. Big Mistake ! My 2003 model gave me no problems at all. I should have kept it instead of trading it in. Since my purchase in 2007 i have replaced the battery, the CVT, and wheel bearings. It surprises me to see how many other people were experiencing the same issues I am. My struts are making noise but Nissan won't replace them until they get worse. I hear some rattling in the engine that the technician says he can't hear. I thought it was the mechanics but maybe it is just the car falling apart and they are used to it. The car shakes at high speeds also.
