Had squealing from day one here as well. Only under 5 kph. I went to the dealer, got them "lubricated" :-) but a day after, the squealing was back. I'm not going back, I'll wait for a real fix (if they finally offer one).
Otherwise, I'm going to upgrade pads to serious stuff next spring.
At least, if I have squealing brakes, I'll have real stopping power!
