Same exact sound under the same situation.. hot day + driving for a while, squeak city!

Changed to coilovers, changed the end links, did not help with the sound..

Replacing lower control arms (need replacement according to the dealer) and swaybar bushing soon, hopefully it fixes it.

Have a 08 coupe (sport, 29k miles) that is having the exact same front suspension noise when hot. Stock suspension, my thought is it's coming from the LCA's...

My old sedan started squeaking over speed bumps and I lubed the sway bar(I think) bushings to make it go away.

Lubing the bushing is low-hanging fruit and quite inexpensive. Try that first before replacing parts.

Do you guys by any chance have a zSpeed aluminum engine undershroud? For the longest time, I had the same squeaking sound over speed bumps and while traveling at low speeds (below 15 miles per hour). As it turns out, my zSpeed aluminum shroud was flexing and rubbing against the Hotchkis sway bar and that was where the squeaking sound was coming from.

Yes degrease the bushings

Are you talking about the lower control arm bushings?
