Zina 
2015 Nissan Altima Sedan 2.5 S 4dr Sedan (2.5L 4cyl CVT)
Squeaky Brakes since i purchased 2015 Nissan Altim
 The brakes seem to be an issue with this vehicle.   I took it to Nissan and they said it was dirt, so they cleaned it and that was early on before my car even reached 15,000 miles.  Now at 30,000 miles the brakes continually squeal when I'm about to stop, when I reverse and it's a constant sound.  Again, Nissan said my brakes passed inspection and no need to change anything but they haven't done anything to fix the noise.  Now it's more annoying then ever, the car is fairly new and it's embarrassing that I can be heard backing out of my parking space or when I'm at a drive thru and need to apply the brakes.  After reading the reviews, I think I will attempt to take it to a mechanic and hopefully they can figure it out.
