The issue people are concerned about is that they might have some minor unrelated engine problem down the line, say a VVEL problem or a sealing problem, and Nissan will take one look at the car and say "You have an aftermarket oil cooler attached to the engine, therefore we're denying any warranty claim on engine repairs", on the basis that the aftermarket oil cooler could have had some malfunction that led to poor oiling which led to the failure. They would be ******** to do so, as it's easy to verify that the oil cooler is working properly, and a properly working oil cooler helps protect the engine. But after the GT-R mess nobody trusts them not to be ******** on warranty issues.
Edit: I'll pre-empt the standard replies:
Yes, the Magnusson-Moss Act is on your side here, in that legally they do have to prove that the oil cooler caused the problem. However, time and legal fees are on their side. They can still say "you're screwed", and then you have to pony up for a legal battle with them, which might cost more than the repair and take forever to resolve.
