I've had the new Uppababy Vista for 6 weeks and it has a fault. The wheels make an awful rubbing noise. I've had 3 replacements all with the same problem. Anyone else? Thinking of swapping it for an iCandy Peach 3 but wanted the Vista originally so feel hard done by that I have to swap! DC #2 due soon so will be using it as a double so want it to function well (especially for the cost 
)!
