2009 Mazda RX-8

Overview

The 2009 Mazda RX-8, a unique sports car renowned for its rotary engine and distinctive styling, presents a mixed bag in terms of long-term reliability. While its performance and handling are often praised, potential owners should be aware of specific areas that have historically shown a higher propensity for issues. The rotary engine, while innovative, requires diligent maintenance and can be prone to certain failures if not properly cared for. Other systems, such as the transmission and electrical components, have also seen some reports of problems. This analysis focuses on documented, non-wear-and-tear related issues to provide a clearer picture of the RX-8’s reliability.

Summary Verdict

The 2009 Mazda RX-8 is a car for enthusiasts who understand its unique nature. The primary concern revolves around the rotary engine, which demands meticulous maintenance, including regular oil checks and a specific warm-up/cool-down procedure, to mitigate issues like apex seal wear and oil consumption. Failure to do so can lead to costly rebuilds. The manual transmission has also seen reports of clutch wear and synchronizer problems. While other systems like suspension, electrical, exterior, and interior are generally less problematic, specific electrical components like ignition coils and power window motors can fail. Prospective buyers should factor in the potential for higher maintenance costs and the specialized knowledge required to keep the rotary engine healthy.
