Just another thought, I'm sorry to hear that it no longer has no dipstick, but it's probably no surprise. It's seems there are too many people out there who wouldn't know how to use one, even if they knew where is was!!
The manufacturer is probably better off with an electronic method of monitoring oil level. At least, that way, they can have ECU logged evidence of neglect when the oil level is ignored during the interstellar service intervals! That should help them with warranty claim disputes!
