In some senses though, this is where the manufacturers make life difficult for their service staff.
With no physical dip measure, only a digital one (which was seemingly saying 'OK'), they're a bit stuck if such a warning message only pops up after driving away for 5 minutes. It puts the dealership in a bit of an awkward spot because it sounds like unless they took it out for a spin, there was no way for them to actually know it was overfilled and you can bet they'd typically get more abuse from most customers if they were seen to be taking GT-Rs out for a spin to 'make sure the oil isn't overfilled'
