The Mazda RX-8 is a unique and often misunderstood car, primarily due to its rotary engine. It's an enthusiast's vehicle that requires very specific maintenance and a deep understanding of its quirks. It's not for the faint of heart or those seeking a purely reliable daily driver.
The most significant weakness is the rotary engine itself. Apex seal failure is a common and expensive problem. Other issues include poor fuel economy, high oil consumption (inherent to the rotary design), coil pack failures, catalytic converter issues, and cooling system problems (leading to overheating).
WOF tips
During a WOF inspection, check for excessive engine smoke (a sign of rotary engine wear), conduct a compression test (critical for rotary engines), and inspect for coolant leaks, suspension components, and brake condition. Regular testing can identify upcoming apex seal issues and avoid a costly repair or rebuild.

Is the MAZDA RX-8 2003–2012 a reliable car to own in New Zealand?
The MAZDA RX-8 2003–2012 is considered a high-risk, high-reward vehicle. Its unique rotary engine offers a distinctive driving experience but demands significant maintenance and has a potential for expensive repairs, particularly apex seal failure. It's crucial to be prepared for these specific maintenance requirements and to get a pre-purchase inspection from someone experienced with rotary engines.
Why does my MAZDA RX-8 2003–2012 use so much oil?
High oil consumption is inherent to the rotary engine design of the MAZDA RX-8 2003–2012. The engine injects oil to lubricate the apex seals, which is then burned off during combustion. While some consumption is normal, excessive or sudden increases in oil usage should be investigated.
