Dude, why do you care what your small-penised neighbors who bought cars that have fewer American made parts than your Nissan does (did you know it was assembled here in the United States?). Their chosen brands have issues too, what's Ford stand for? Fix Or Repair Daily, yeah that nickname was derived from super reliability.
What would you like to bet that your neighbors have had similar issues from their vehicles that they've had serviced @ the dealership because they can't tell the difference between a wrench and a wratchet?

But whatever, you're bitching about a 7 year old vehicle needing maintenance. 7 YEARS, jesus get over yourself.
