I not sure what the problem is but I do know if you back up over five miles per hour the park assist will shut down in reverse and you will get a message to that effect on the dash. I had the same problem with one of mine and the dealer told me that it is designed that way to shut down. Try backing up under five miles per hour and see if you have the same problem. Hope this helps.
