Every year J.D. Powers publishes a wide range of automotive surveys, but none is more important to the average car consuemr than their annual Dependability Survey.  For 2019, Lexus once again tops the list as it has for eight years. But Porsche was a close second and tied with Toyota in third place.  Two General Motors brands, Chevrolet and Buick, were in fourth and fifth place, dispelling again the myth that U.S. brands trail in vehicle quality. For the first time in the 30-year history of the survey, all German brands finished above average. In fact, the Porsche 911 was named as the single most reliable car. This survey measures the reliability of 3-year-old cars and covers 33,000 respondents. It is the most scientifically and comprehensive survey of its type.
