Was driving and had a bunch of warning lights all of a sudden come on then the speedometer dropped to zero. The car drove fine and made it home no issue but when I went to leave next morning the car would not start or turn over.

It sounds like a module has gone out or something shorted and popped a fuse. Let start by doing a fuse check (systems on). this guide can help you with the fuse locations in the images below:

If the fuses are all good and have power let's do a CAN scan. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

To me it sounds like the BCM might have gone bad, but we need more information to be sure.
