Quinny buzz when i am pushing the pram every now and then it will click out of place like it wants to shut itself back down, when my baby is in it and it does this its very worrying also if i am pushing it up hill it sometimes clicks out of place at the sides any suggestions is this a normal fault or anything do you know

Has the brake cable come outy of position and is stopping it opening fully? This happened to mine and was easily fixed!

My Hydraulics are fine, but the problem is the metal piece that the hydraulic rod presses against to provide resistance is broken.   Does anyone know where to get it repaired ?   I bought the european one and is out of warranty as well.  Can you send the chassis to dorel in usa and pay for a repair ? 

I had the exact same problem with my quinny buzz. When i went to get it repaired i was told that we had broken the gas line in the hydrolics in the frame. When i tried to collapse the buzz for the first time, when i got the the point where you meet some resistance (if you haven't pressed and pushed the buttons properly) i forced it closed which broke the hydrolics. This can't actually be repaired but the pram can still be used safely as long as you manually snap the frame up, ensuring it locks into place. The two black parts meet at the top when it's locked in properly so you should be able to see if it is or not. Make sure when you collapse the pram that you do press and push the buttons fully. You should meet no resistance and it should collapse freely when this is done properly. Hope this helps!
