Thanks all, the battery was replaced a little over 2 years ago (NAPA, i work for them). I'll swing by the store today and see about getting it warrantied.
This morning was fun, on the drive to work I noticed weird voltage swings and my headlights flickering at idle so I figured it would have a power failure when I turned it off, went to the dealer on the way to work, but the Z was behaving its best there. Once I got to work 10 minutes away, thats when she decided to fail. Got some video of it, thought I would share for the curious.
After turning off, I have zero power to anything, then the below happens.
A few minutes later this was the status of the car
Less than a minute from that video, car turns over just fine.
