The Mazda MX-5 Miata tops Consumer Reports most reliable vehicle list for 2020.

Newer isn’t necessarily better, especially when it comes to cars and how reliable they are. Keep that in mind when reviewing Consumer Reports latest “Auto Reliability Survey.”

Updated models or entirely new replacements for outdated models certainly attract a lot of attention when they hit the auto show circuit or dealer showrooms; however, they often come with new technology or applications that can be prone to problems.

“When you redesign a new vehicle, often you get better fuel economy, better safety, potentially better features,” said Jake Fisher, senior director of auto testing for Consumer Reports. “But if you want … reliability, your best bet is to wait a year or two until those initial growing pains have been worked out.”
