Common Issues and Problems with the Used MG4 Electric


First Generation (2022 - Present)

Software Glitches and Infotainment System Problems

Owners frequently report issues with the 10.25-inch touchscreen infotainment system. Problems include the system being laggy, unresponsive, unexpected freezing, or failing to start. Navigation and Apple CarPlay/Android Auto connectivity can be unreliable, often requiring repeated attempts or specific sequences to connect.

Common Solutions: MG addressed many software bugs via dealer firmware updates from mid-2023 onward. A soft reset (holding the home/power button) usually clears temporary freezes. For stable phone integration, owners recommend using a high-quality wired cable.

MG Pilot (ADAS) Over-Aggressiveness and Phantom Braking

The MG Pilot ADAS suite drew criticism in early 2022 models. Lane Keep Assist (LKA) was overly aggressive, pulling the steering wheel abruptly. Phantom braking from Adaptive Cruise Control (ACC) was also common, triggered by roadside objects or oncoming traffic.

Common Solutions: MG’s Spring 2023 software update improved ADAS behaviour, reducing phantom braking and softening LKA. For used cars, confirm the latest firmware is installed. Many owners disable LKA at startup if they find it intrusive.

Real-World Range and DC Charging Speeds

Drivers note that real-world rangeis lower than WLTP figures, especially in cold weather or with heavy HVAC use. Charging speeds rarely reach the advertised 117 kW(Standard) or 135-150 kW(Long/XPower), often averaging ~60 kW before tapering.

Common Solutions: Pre-conditioning the battery and cabin helps reduce winter losses. MG software updates improved thermal management, but the charging curve remains conservative compared to rivals.

Mechanical Faults and Undercarriage Weaknesses

  • Transmission Oil Leakage: Early 2022 batches had minor leaks from the reduction gearbox due to a faulty breather valve.
  • Undercarriage Protection: Owners highlight limited underbody shielding, leaving wheel well areas exposed to debris.

Common Solutions: The leakage issue was fixed in later production runs; confirm repairs on early used cars. For underbody protection, aftermarket coatings or liners are recommended.


Conclusion

The MG4 Electric delivers strong value and performance in the used EV market. Buyers should focus on ensuring firmware updates are applied to resolve infotainment and ADAS issues. Mechanical faults were minor and largely corrected under warranty. While DC charging speeds may not match peak claims, the MG4 remains a practical, affordable compact electric hatchback with high owner satisfaction once software refinements are in place.
