COMMON FAULTS 

Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel. 

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.
