Give them as much time as they need to get it right, but stay in touch with the service advisor. The rental is on their dime, so don't sweat it.

The car should not throw codes, hesitate on acceleration, or do anything out of the ordinary. Don't accept the car if it exhibits any symptoms whatsoever.
