I get a squeak from the rear, but only after the car's been exposed to rain, then has sat overnight so the springs/bushings/other uncoated bits back there have had a nice long chance to get good and rusty (my theory is that it's rust, I don't know for sure).
My squeak happens when the suspension moves a lot but slowly, like when backing down a down-sloping driveway, and you go over the curb, so the rear springs "hyper extend", if that makes any sense. Then it squeaks badly until the rust (or whatever it is) gets worn away.
And I agree, it's asinine for a nice new car to have this problem. I almost traded mine last year because I was so frustrated with that problem, and another intermittent noise that seems to be unique to mine. I never had a Japanese car making crazy noises like this, that's for sure.
