Hi there, I witnessed many recalls when with Ford - and to be fair, the decision to implement a recall is taken fairly near the top of the tree (i.e. out of the dealer's hands). The company will first have identified a build-range of cars/models affected, collated the details (they have in conjunction with DVLA of those cars' owners), and built-up stocks of remplacement parts. It is only at this point (and it would be pointless to write before then) will they simultaneously contact owners and dealers.
It is important to remember when your car is subject to a recall, that your car is no less safe/reliable than it was before you were notified, unless it displays symptoms pertinent to the recall. As such, book it in at your earliest convenience, but don't panic.
Frustrating though, I know.
