To that seems like a huge problem.
As for the huge problem you posted I assume you where referring to the sunroof incident. Here is my thoughts about it. I have never heard of this before but I don't deny it did not happen. I myself have a manual sunroof in my tacoma and there are three hinges that hold the glass in. You can unhook all three and take out the glass. It's nice in the summer but can be a pain to take out. Anyway back to the point if he did not hook the hinges in correctly I could see that happening, But for the sake of argument lets say they where hooked correctly. Sunroofs on a tacoma is not a factory option but a dealer option. Who ever installed the sun roof dealer or sunroof shop did not do it right. I can believe the dealer might not have done it right. I don't trust some of the toyota dealers I live by, but the tacoma did not come from the factory with that problem.
