I won't accept any excuse from FMC. They've known about this issue literally for years - years! Yet they keep cranking out cars with the same problem. That tells me a lot about how they view and value their customers. If they are unable to fix my car, then they can replace it. Period.
The vast majority of cars, just as "complex" as a Mustang, are somehow able to be manufactured so that they don't squeak, rattle, clunk, or otherwise annoy drivers and passengers until late in the game. The fact that these Mustangs can't even make it to 2,500 miles before this stuff starts is simply unacceptable.
I didn't buy a used, dilapidated car; I paid for a new car. I don't and won't "settle" for mediocrity.
