Mazda RX-8 (2003-12)

The Mazda RX-8 is known for its unique rotary engine, but it does come with a few common issues. Here are some of the most frequently reported problems:
1. Engine Problems: The rotary engine in the RX-8 is known to be unreliable, with issues such as leaking apex seals, engine flooding, and overheating.
2. Starting Problems: Faulty starter motors and ignition system issues, especially in cold weather, can make the car difficult to start.
3. Power Steering Problems: Some drivers have reported intermittent power steering failures.
4. Catalytic Converter Failure: The catalytic converter is prone to failure, which can lead to poor performance and increased emissions.
5. Ignition Coil Failure: The RX-8 tends to wear out ignition coils faster than other cars, often requiring replacement every 30,000 miles.
6. Excessive Oil Consumption: The rotary engine consumes more oil than typical piston engines, requiring frequent checks and top-ups.
Despite these issues, many owners still love the RX-8 for its unique driving experience. If you own one, regular maintenance and being aware of these common problems can help keep it running smoothly.
