Common Faults & Reliability

These are the most common documented problems for the MG HS Mk2, sorted by their typical impact and frequency.

Dual 12.3-inch Screen Touchscreen Boot-Up Lag & Climate Control Latency

PHEV High-Voltage Battery Thermal Management Valve Seepage

medium severity

On HS PHEV models with the large 24.7kWh battery pack, the high-voltage battery cooling circuit diverter valve can develop slight weepage at the hose union clamps under high thermal loads.

7-Speed DCT Low-Speed Roundabout Roll-On Hesitation
