I saw that exact chart discussed elsewhere. The general trend I concluded was this is a measure of how picky a brand's customers are. Since "problems" is left undefined these could be anything from "I don't like this button" to "the engine randomly stops running". Audi and Volkswagen; Chevy, GMC, and Cadillac; Ford and Lincoln, etc are essentially the same vehicles. I suspect the more luxury you go, the higher the expectations you have for your vehicle. The interesting exception is Lexus and Toyota. Anecdotally, I'm surprised to see Subaru with such high defects. I know a lot of friends with Subaru's and have only heard one bad thing - the seat springs wore out after several years of daily driving.
