That may be true prior to the initial owner registration, by some manufacturers, but not all of them.
I remember a GM dealership that was having their lot repaved, and there was a Cat bulldozer parked at the end of a row of cars overnight. A vandal jumped into the dozer, and started it up, leaving about 20 crushed new vehicles in its wake.
Those vehicles were not returned to GM, they were written off by insurance and sold at SMI, a salvage auction that's based near here.
I know someone else who yesterday asked me about a car that he's considering purchasing.....a flood damaged 2009 Accord EX V6 coupe.
