Read about this a couple of times, but not sure when cars starting having it. Do facelift STs have this?

I have an 06 facelift and it occasionally doesn't start first go. Usually goes second go, but sometimes have to have my foot slightly down on the throttle.

Any way I can check if its had the update?

Cheers,
