Consumer Reports auto testing and reliability: Top six myths busted
With the recent release of our annual car reliability data , there was widespread coverage of the findings that showed Ford stumbled with some new cars, Chrysler made dramatic improvements, and the Japanese automakers dominated the top 10 brands, joined notably by Volvo. However, not all media outlets seemed to understand or explain our methodologies. So, let’s clarify a few key points around the reliability survey and auto testing , busting those myths before they spread further. The same people who test toasters and coffee test cars. Nope. While we take nothing away from our colleagues who do test toasters and coffee, Consumer Reports’ Auto Test Division has its own dedicated staff and facility. Most of us have worked in the automotive industry before coming here, including stints at General Motors, Land Rover, Ford, Nissan, and Pirelli. And everyone who tests cars has been to high-performance track driving schools, and some staff members even teach them. Plus, many of us have true racing experience, as well. Consumer Reports recommends Toyotas without even driving them. False again. In order for CR to recommend a car, several things must happen: CR has to buy the car and test it; the car must first score high enough in our tests to be recommended; the car must receive average or better predicted reliability based on our annual survey results; and the car must perform adequately in the Insurance Institute for Highway Safety (IIHS) and National Highway Traffic Safety Administration (NHTSA) safety tests, if tested. For some redesigned vehicles, CR will predict above average reliability if the previous outgoing model was consistently very reliable. It has always been this way, and always will. Consumer Reports reliability data is biased because it only surveys subscribers. We’re proud of our reliability data . It is based on the largest survey of its kind, with over one million responses. That covers quite a variety of people, as evidenced by the critical letters from subscribers we get every day. The responses also covered over 300 domestic and imported models, the majority of all the new and used models available in the past 10 years. Do we brainwash people to, say, like certain cars that do well in our tests? We don’t. And if we did,...
