2010 KK not turning over sometimes

OK, so I've been having some electrical quarks lately and can't really find my specific issues in the forums so here it is. The biggest issue...sometimes I try to crank it and nothing happens engine wise, the Vehicle Security light flickers...comes on for a few seconds, and the TPMS light does the same; but the engine never even makes an attempt to crank, just silence. I rotate the key back and forth a few times, remove it and try again, all with the same result. Finally, and randomly, it'll decide to crank as it normally should.

The other issues that I assume to be related; sometimes when driving, the Vehicle Security Light and the TPMS light will chime and come on for a few seconds then go out (all the tires including the spare are fine). And last and probably least, the rear wiper gets a mind of its own sometimes and won't shut off, I have to turn it on/off a few times to make it stop.

I know there's a few points of failure for electrical systems, I'm checking fuses and stuff, but if anyone has some more direct advise I would appreciate it, Thanks to all for the help

Just in case anyone runs into this same issue the solution was pretty simple. I took it to the dealer to be checked out and they called me back in an hour (I assumed it would be much longer) and said it was ready. They told me there was an ECU update/flash specifically for the issue. They took care of it for free and replaced my wipers for me for free... I was impressed. Hope this helps someone else.
