Known faults for Mazda Mazda RX-8
Our database tracks 3 specific mechanical faults and recurring failure patterns identified across UK MOT testing stations for this generation.
MOT Roadworthiness: Good
This rating reflects historical MOT pass rates and recurring advisory wear patterns from official DVSA test logs. Note that roadworthiness does not verify outstanding finance, insurance write-offs, or stolen records.
Verify lender finance agreements, insurance write-offs, police stolen registers, and mileage rollback.
Common Problems: MAZDA RX8
Known issues reported by owners and MOT testers.
- Low Compression and Hot-Start Failure(Serious)
Wear in the rotary engine reduces compression, making the car increasingly hard to restart when warm and often leading to an expensive rebuild.
- Ignition Coil Failure and Catalytic Converter Damage(Moderate)
Weak coils cause misfires and incomplete combustion, which can quickly overheat and destroy the catalyst on a rotary that already burns oil by design.
- Rear Arch and Sill Corrosion(Serious)
UK RX-8s rot around the rear arches, sills and front chassis rails, and fresh underseal can hide serious structural work.
