I'm guessing you are talking about a factory warranty. But my opinion-either way (factory or aftermarket warranty)-is that a "license repair facility" has to perform the 'scheduled' maintenance.
I just went through this whole process with an aftermarket warranty provider. The sale lady tried her best to convince me receipts and personal record were fine. But I kept going back to the paperwork and all I ever saw was "licensed repair facility". Turns out, she did some checking with the higher ups and sure enough, personal record keeping and receipts ARE NOT adequate records to keep a warranty (the one I was looking at) intact. I'd check into it a lot more before making a potentially expensive mistake.
All that said-I've never bought a new vehicle. Surely the same does not apply.
