Lost lights while driving!
So I was driving tonight coming home from dinner when I noticed that my radio was cutting in and out everytime I used the turn signal and brake. I figured it was just normal draw. Then going downhill on the freeway going 75, my headlights and dash lights went out, service engine soon light came on and I was driving in the dark for a few seconds. 
I finally got power back and DIC was now clear. My lights kept on dimming everytime I brake or use my window as I limped home. When I got out of the car, the seats and wheel did not go to easy mode. Battery is less than 6 months old and all the connection seem tight. As a precaution, I have a battery mat to protect against leak. Any ideas? Hoping it's just another battery going bad.

I'd suspect the battery leads with such a major failure
Do you have a raft of U codes on the DIC? That would suggest a power glitch.

Update
Well, I parked her for two days and when I cranked her up tonight, no problem. I drove her for an hour on the freeway and the voltage remained steady at 14.1 and coming back home, it was at 13.8. Did notice a fluctuation after I parked her for a few minutes and the ABS/ traction control lights came on again. The voltage started to go from 13-14 and as quickly it appeared, it disappeared.
Coming home was fine again, no dimming of lights and fluctuating voltage.

You said you checked the connections so this probably isn't what's wrong, but this happened to me in my Camaro and the battery cable wasn't tight. I thought something major was happening.
