It sounds like the BCM is going out, but we need to do a CAN scan to be sure. 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:

Here is how to change the BCM out is case you need it. You can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please let us know what happens.
