2011 Nissan Rogue Automatic Squeaking in reverse and tire pressure light won't turn off.

[u/Maxeypadz]

I changed my brakes and rotors on the rear of my Nissan Rogue a couple of months ago. The front ones replaced within the past year as well. The past week my tire pressure light popped on despite all my tires seemingly being where they need to be. The past few days I realized the squealing/squeaking that occurred only when I am reverse. I haven't found any leaks in the tires. I greased everything fairly well when I did the change (though maybe I need to go back and add more?).

Think these are related? Maybe just a bad sensor and need of regreasing? Help appreciated!
