Does anyone use the UppaBaby Mesa?

We got the Vista/Mesa combo for LO. DH installed the car seat on Sunday and the base is level and does not move - it's really in there. 

When we put the infant seat in the car and drove with it, it was rattling quite a bit. When we held the seat down, the rattling stopped. Anyone else experience this? I have an appointment to have the seat inspected next week and if it's still rattling then I'll contact UppaBaby. 

Thanks for any input!

We've never noticed any rattling with our Mesa and we've driven with it in the car without the baby inside.

I just got mine and it's doing the same thing. What ended up happening with yours??
