When you buy a car, it is yours. It isn't the property of the manufacturer anymore. Over the years, I have dealt with countless individuals who don't get this concept.
Subaru made a bunch of "Phase 1" DOHC 2.5L engines from 1996-1999 that suffered from head gasket failures. (yes the SOHC engines have some HG problems, but different in nature and lower incidence)
Subaru covered quite a few owners even after the warranty was up and by 1999 (Forester) 2000 (all others) the engine had been dropped completely.
But, today, I often speak to owners of the 1997-1999 Legacies with the engine and are having a HG problem at some outrageous age/mileage, and they scream that Subaru should cover the problem. I am all for makers doing right by customers, but a repair on a 12 year old car? C'mon, get real.
Do I think they should have changed the design faster once they knew about the problem? Yes. THAT is what pisses me off. Some makes just keep making the same problem year in and out, never changing known major defects.
