I had the same problem. A trip to the dealer for an update fixed the problem. This was last month.
The dealership did mentioned that i should capture a video anytime the problem occurs again so that I can file for a warranty claim. I came under the impression that if i had a video of the unit freezing Toyota would warranty it without too much hassle.
