The Mazda CX-5 has generally received positive reviews for its stylish design, agile handling, and comfortable interior. However, when considering the best and worst years, it's crucial to examine specific model years and their respective features, reliability, and user feedback. Generally, the 2017 Mazda CX-5 is often praised for its redesign, offering a more upscale interior and improved driving dynamics. On the other hand, earlier model years, such as 2013 and 2014, have been reported to have some issues with infotainment systems and a less refined interior. It's important to note that vehicle reliability can vary, and individual experiences may differ. For the most accurate and up-to-date information, it's recommended to consult reliable automotive sources and user reviews specific to the model years you are interested in.
