2013 Nissan Sentra Sedan SV 4dr Sedan (1.8L 4cyl CVT)
Only 5,000 miles with issues!!
 I have experienced problems with the AC blowing hot air and the rear brakes developing a loud metallic grinding/crackling noise. The first time I took it to the dealership they kept the car overnight - the service adviser said there was a service bulletin on the brakes and the brake cylinders needed some lubing. They had no idea why the AC was not cooling periodically. I picked the car up and after a week or so the brakes had the same issue and the AC was HOT all the time! Very uncomfortable driving in 100F+ weather with the windows down! The dealership kept it for 2 nights and figured the brake cylinders had to be replaced as well as the AC compressor. Covered by warranty but what's next???
