Believe it or not that squeak is common at least on the 3.6L engines too and it's not the engine. Tell your husband to press the brake pedal super gently when starting it and see if the squeak goes away. It did on all three 3.6L we had. It' has something to do with the brake booster.I have the same engine and have not experienced what you have laid out in your post. I actually love that engine, compared to my daughter’s 2.0T which sounds like a bloody tractor when she starts it. My husband’s 392 has a squeak when he starts his. Might just be a quirk that you either live with or trade it in for something else.
