From the above chart, one might conclude that the quality of cars in general has improved greatly since 1996. This is actually misleading. The fact is that the 2006 model cars have been on the road for 11 years while the 2018 model cars are still fresh from the factory. Table 2 gives a better picture of car quality. It shows the problems reported in a car's first year of service. One can see that the quality of cars has been fairly constant over the years. The exceptions are years 2008 and 2009, when the global economy slowed down, causing new car sales to plummet, so few problems were reported.
