Do the brakes squeak?
I currently have an '07 GS 450h and the brakes are embarrassingly squeaky. Does the new gen have this issue? I'm considering getting a '13+

My '13 GS brake start squeaky like hell today during stop and go traffic, although I bought it new and now still less than 17K on the odometer. I also experienced the ticking rolling noise when driving slow in circle but I do hear the ticking noise today on freeway speed when driving parallel with semi truck and window down. I took it to dealer a month ago to checking the noise but they said it normal for Lexus vehicles to have that kind of noise. My "08 GS brake also squeak like hell despite they change the pads 3 - 4 times. For sure my next ride won't be Lexus.

Yep factory pads squeak on this car, at least on my F Sport. Keep the front wheels clean is the best advice I can give. Take it to the spray wash once a week and hose down the front brakes, or swap to akebono or other "ceramic" pads.
To the guy with the 2013 that ticks slowly in a circle, the dealer has to fix that. It's a common issue with the floating front rotors and there is a TSB for it. I had a tech ride with me with the windows down in the dealer parking lot and he heard it in 5 seconds flat and knew exactly what it was.

Hi performance brake pads are soft for greater friction, so more dust is produced, and if this dust is not cleaned off regularly through washing, the accumulated dust will cause squeaking.
My front door neighbor's E Class Benz makes the same squeal.
He changed to ceramic pads, which produce less dust, so the squeal is gone, but so too his stopping power has diminished!
Ceramic pads are better for racing, because repeated braking under racing conditions raises the ceramic pad's temperature for superior grip, and at high temperatures with repeated braking, the ceramic pads are more resistant to wear.

Remove the front wheels & wash them thoroughly, and the noise is gone.

Anyway, good luck with second dealership. This isn't normal and it isn't incurable.

Remember when the car was brand new on delivery?
The brakes didn't squeal when driving home, did they?
They only squeal as front brake dust built up, and it wasn't removed with high air pressure, or washing.
Notice how the front wheels gradually turned black, if not washed regularly?
I have changed both front rotors, front pads, and both front shims, all OEM parts, and at first the squeal goes away, but after a month or so, the brake dust builds up, and the squeal is back.
The secret is to clean the front wheel & brake assembly thoroughly & regularly, and be prepared to actually remove the front wheels with a cordless impact wrench [for speed & convenience] when necessary to do a more thorough removal of all brake dust.

In the old days, the pads used carcinogenic asbestos, and that prevented the squealing.
The other way is to find a harder set of metallic pads, but then compromise on braking power.
Ceramic pads will compromise on braking power too - until they heat up with repeated braking.
One day, try and replace with brand new front: rotors, pads & shims, and you'll notice the squeal immediately goes away for a month or two, only to return as brake dust builds up.
The brake dust causes the brake pads to vibrate at hi frequency causing the squeal.
The shims try to absorb the vibrations, but they can't when there is too much dust built up.
Mercedes E Class etc, all have the same problem.
Camry doesn't, but then Camry is over 400 lbs lighter.
