I attach some data I saved about RC4.
I find that disappointing, but maybe I expect too much.
I agree the Dealer could have done it pre-delivery, but the RC4 Service Bulletin says:
"
Application to Production Line:Application to production line to be confirmed at a later date.
Market Treatment:Repair on customer complaint only."
So it is not clear when it would be applied to new production cars, and Dealers are told to it on customer complaint only to existing cars, which would include new stock.
It wouldn't surprise me if new cars today are being delivered on RC3.
