New Owner - Help!

Hi, I've recently purchased a nearly new ('57 plate) Bravo from a dealer. However, on the day of collection they told me it had to be returned to the service department to correct an oil leak - even though there's only 99 miles on the clock. They told me this is a common fault and that a lot of stock was being recalled across the UK to correct this. Anyone else experiencing this?
Also, I've been told about making sure I receive a master key as I'm pretty sure the dealer advertised the car as having only 1 set of keys - surely i should at least have a spare set?

I bought a 07 plate Bravo back in October and although it had recall work done to it since i had it an oil leak wasn't one of them as far as i am aware, there have never been as i far as i know been any oil leaks,and i haven't been told about a call back on that either.
As far as keys are concerned i got one flick key module and one standard key.
