Is it a problem if you don't notice it?

Problems experienced by original owners of three-year-old vehicles

Looking at this chart got me to wondering if it is accurate. Maybe we aren't looking at the actual number of problems, but the psychological profile of people who buy these cars. Maybe people who buy Volvos and Volkswagens are more particular about their cars, and people who buy Lexii are just oblivious. Or maybe people who drive Lexii have other things on their minds and can't be bothered with problems with their car.
