In circumstances such as these, don't listen to people's speculations and jibber jabber on forums. Hire an attorney, follow attorneys advice.
I'd delete these pics, and keep it as quiet as possible. Meanwhile keeping full documentation as to EVERYTHING from recording conversations, etc.. For trial, media exposure, etc..
You potentially caught a design flaw in their machining/assembly of the vehicle, which could potentially save them hundreds of thousands of dollars.. Keep it quiet and heed to advice from attorneys. Who knows.. Toyota may GIVE you the car free (repaired) with a gag order. They may also give you a sum of undisclosed $$.
You have questions, Write them down. Consult an attorney.
At a minimum, I would settle for nothing less than a full vehicle replacement at dealer's invoice. (way below msrp) because it was as much the dealerships fault, as the manufacturer.
