Squeek when Breaking on 2012

[YodaBird]

I took my 2012 for an Oil Change (1500 Km) one of the dealers told me, I don't need to it's too early, I did it anyhow, it was free. I also mentioned something that has been going on for a few months, whenever the car breaks there is a little squeak, even slightly breaking, at the Toyota Repair the guy said the breaks are fine, it's still new, the other guy told me, because it's new you have to give it time, if the squeak continues come in a month, all they did was look under the car, they didn't even drive it and said they couldn't find the "squeak". The squeak can vary from a slight squeak to a louder squeak to sometimes no squeak at all.

Then I came across this thread, it wouldn't relate to the squeek I'm having would it ? Why is a new car getting Squeaks, weather or drying out play a part ?
