When I bought my first Volvo about 35 years ago they had an almost guarenteed goodwill system (they called it something but memory fails me) of part or wholly paying for things out of warranty if it didn't meet servicable life. Partly I believe because the build standard was much better and thus failure rate much less. That has faded away over the years. I now have a fault on my XC60 central locking rear door and find it's a common fault (same parts used as other makes) It would never have happened on my old V70 25 years owned and had an o2 sensor fail after 8 years replaced it and that has been the only fault. To be fair XC60 is 10 years old only other fault egr done under warranty
