From what you have described here this sounds like a low voltage fault due to a weak battery or failing alternator.I have seen these cause this issue here before.It is also possible this is a fault with a computer shorting out or failing internally intermittently causing all messages to appear.It is an electrical fault since you can cycle the key off and on to correct it temporarily.
I would have the battery and alternator tested as well as fault codes checked with a fully compatible scan tool to see what codes are set as this will help diagnose the issue here.
I believe the battery on this model is in the trunk area and may be hidden under some paneling although some were mounted under the rear seat cushion depending on the model
