VW and Subaru don't rank near the top of anyone's reliability rankings. You don't seem bothered by the problems, but if you were you could always buy something like a Toyota/Lexus.
and yeah, Subaru doesn't rank too badly (sixth) on that list. I always thought of Subarus as being good, long-term powertrain reliability notwithstanding. The gas mileage they're getting while running normally-aspirated, full-time AWD powertrains is pretty impressive. I can't imagine why the parent's car was so utterly screwed up, but I wouldn't be happy about a problem that required me to turn the car off and take the key out.
I think the advice on getting a Toyota or a Lexus if you want to maximize your odds of not having problems like the parent described still stands. The conventional wisdom is that their reliability comes from making continuous small changes to their models instead of waiting to make major changes, although next year's Corolla hatchback looks like a pretty major one. It will be interesting to see what the first-year reliability of that model is.
