Yes from all reports seems like a lottery if it works and a massive general resistance from Toyota to ack their issues, listen to the consumer and fix it. See my post in steering shaft issue: told them I heard a noise like xyz they then fix it under warranty because the issue is rampant and known. Tell them all about head unit issues including where 6 times in 6 months its lets out an enormous bang, turns off radio/ipod and whole family recovers from what sounds like a gunshot going off in the cabin. Toyota response is we cant really do anything until we hear it. Maybe I should just record a gunshot in a confined space and tell Toyota I recorded my noise by constantly recording everytime I drove the car and see what they say. Seems fairly simple to me: a loud bang is a loud bang and the head unit turning itself off seems pretty simple as well plus bt issues. Things happening which shouldn't happen, therefore do something about it Toyota!
