Consumer Reports (CR) is the go-to source for finding reliable data for many driving consumers. That data is then used to determine which car would be perfect for them and their families. One significant source of information provided by CR is the company’s reliability reports. The data for these reports come from the Auto Reliability Surveys filled out by CR members. Respondents report on problems in each of the 17 trouble spots. So, what are these 17 trouble spots, and what do they mean?
