Common Problems: MG ZR
Known issues reported by owners and MOT testers.
- K-Series Head Gasket Failure (HGF)(Serious)
The K-Series engine is prone to head gasket failure due to its small coolant capacity and plastic locating dowels that allow the head to shift.
- SCU / BCU Failure (Pektron)(Moderate)
Later models (2003+) use a Pektron SCU that controls windows, fobs, and wipers. It is notorious for relay failure.
- Worn Front Suspension(Moderate)
The front suspension bushes and ball joints wear out, leading to vague steering, knocking noises, and poor handling. This is a common MOT failure point and can be exacerbated by hard driving.
- Coil Pack Failure(Moderate)
The ignition coil pack is known for failing on the ZR, causing misfires, rough running, and difficulty starting.
- Door Lock Failure(Moderate)
The door lock actuators, particularly on the driver's door, are known to fail, making it difficult to lock or unlock the car.
