2008 Scion xD wont start

Thanks for the suggestion Rasmataz. After exhausting all that I could do we finally hauled the car into the local Scion dealership. I need some input and thoughts into what I have been told now. The car has been there for four days nd they are telling me that the computer is not talking and responding to the computer (wtf?). I think my computer is crashed. They have been on the phone with tech and have tried resetting everything and have still not solved anything. I went in to retrieve some belongings out of the vehicle and it is TORE UP! I know they are trying to find the problem. My backseats are even out of it and the hubcaps off. Now, get this, they are leaning toward lightning damage because they cannot find the problem. What the what what? Here is the issue for me, the car is under warranty I even recently upgraded, but if they say it is lightning, then it becomes the responsibility of my insurance for repair costs. In turn my insurance is going to say prove it was lightning. See the vicious circle I am afrais is forming? Meanwhile I am without transportation that my warranty is supposed to cover while my vehicle is being repaired, but they cant pinpoint what the problem is. How should I handle this whole ordeal? Thanks.

So what should I say to them? Im starting to get a little pissed. If they try giving me the run around tomorrow, Im not sure what to do. They even me that they looked at my car for lightning damage, but couldnt find any. Then told me that they had cases where lightning didnt actually hit the car just near it and it caused the computer damage.
