Problems getting past lock screen, and the bluetooth doesnt work

[Joel96]

I have lovingly used my nexus 5 for close to 2 years now and never had a problem. even with the update to Marshmellow i didnt experience anything bad. then two weeks ago every time i swiped up to get past the lockscreen the screen would go black and everytime i swipe it up it does this however it doesnt turn off. it just shuts the screen down. It also isnt letting me connect onto the bluetooth of my car, any ideas on what i should do?

Clean out the cache, uninstall apps recently installed, and as a last resort factory reset.
