Honda had 20 year old tech on my departed 2010 Accord. I'm talking major components (engine, trans, ect.) so the likelyhood something goes bad is low since 20 years is a lot of time to work out kinks.
A car like the CX-5 where its engine, chassis, trans, ect. were mere blueprints ony 3-4 years ago may come have some issues but yet to hear of anything yet.
Personally I have no interest in owning a car with 20 year old technology. The better automakers can do proper durabilitly/quality/reliability testing before first customer shipment of newly designed models. I'm impressed with what Mazda has done with the CX-5, the early ownership experience is similar to my Lexus IS (a 2007 model, being the 2nd year of a new gen model).
This is a 2012 survey, but what year are the cars surveyed? If the average 50K miles, then they are all at least 4-5 years old (for UK). So this is about the cars made 4-5 years ago, which does not necessarily predict how current cars would do.
