Well, Like I said, Bose is the best upgrade for the price. I've done competition audio in my past and spent a lot of money on upgraded audio in both my past trucks and two boats. For what Bose added in cost, It's a fantastic sounding system. Like any audio system, you have to know the limits and stay within them.
My dealer is very good. I didn't say I could take it in and get anything fixed... I said I would have it addressed. Sometimes the truth is not what you want. Aside from that, I have had no reason to take my new truck in yet.
I am sorry that you feel bitter about you truck, but in your case, moving to a different brand is the best decision. Find a product that will meet your expectation. I am brand loyal, so my expectations are met, perhaps with bias, by Chevrolet.
I wish you luck.
