I would not get another car, not yet anyway. I would do a CAN scan first to see which codes are stored.

To me it sounds like a bad BCM, here is the location if you want to try a preprogrammed unit from eBay or by searching Google. It would be nice the have the CAN system code that is telling us the BCM is bad but this is the only thing that connects these systems and allows the engine to still run. Thanks for the video it helps.
Check out the images (below). Please upload an image or short videos in your response of the problem when you find it. Disconnect the battery before you begin. The BCM is under the dash on the passengers side.
