2 known faults
British breakdown and repair sites describe a head gasket with a reputation for fragility on the ZS, with coolant loss and overheating, more common on older or high-mileage cars (Bumper). The sources give neither a failure rate nor a specific engine: treat it as a point to watch.
Random dashboard warning lights, faulty adaptive cruise control (Bumper); unresponsive touchscreen or lost CarPlay/Android Auto connection.
