It's probably your battery since you didn't register it. You can check on realoem to find the price of the alternator. Mine was replaced under warranty, but I was thinking the parts cost was around $700.

Here is a video I took when my car started going crazy. I was on the highway 150 miles from home. I got some of the same messages as you along with the steering wheel being hard to turn. Pay close attention to the speedometer as well. Pretty scary going 80 mph and having this happen.

Edited the terrible curse words out of the video.
