This happened on my 2012 Altima, and it turned out to be two things:

  • The alternator died
  • The connection from the alternator to the battery was loose at the battery terminal

When I tested with a multimeter, the voltage was always 13.514 or so. A local shop was able to put a proper alternator tester on my car, and that confirmed it had failed.

The loose connection was my own fault. I put on an aftermarket battery terminal, and the alternator wire connection worked loose. This may have cause the alternator to die.

The problem went away when I fixed the loose alternator wire connection, and replaced the alternator (with a new one from Amazon, for significantly less than auto part stores).

In my research I found that when the battery and brake warning lights come on at the exact same time, it is a Nissan way of indicating a problem with the Alternator. However, my sources were all 2nd-hand, and not from Nissan.
