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.
