Some MG4 owners have reported oil leaks from the gearbox breather valve, possibly due to overfilling during production or a poorly designed valve. Newer versions may have fixed this, but it's unclear. MG hasn't addressed this publicly. The AC temperature reading is inaccurate, showing 5 degrees higher than the actual cabin temperature. This can be annoying, but a software update might fix it. The automatic door locking cannot be turned off in SE and Standard versions when starting the car, which some users find inconvenient. Trophy and Luxury versions have this option. Automatic headlights in auto mode come on almost all the time unless it's extremely sunny due to an inaccurate light sensor, possibly tuned for cloudy conditions. A clever owner found a fix by drilling a tiny hole in the sensor cover. The navigation system doesn't show chargers on route, a significant drawback for an EV. MG Germany has promised an improvement for the 2023 Luxury version, including battery preheating when navigating to a charger. The infotainment screen sometimes freezes and stays black, but holding the home button for 10 seconds restarts it. Some users also mention the parking camera not turning on, a bug seen in other expensive cars too. The lane keep assist turns on automatically every time the car starts and is considered poor quality by some users, who manually turn it off. This is ironic as NCAP tests award points for automatic lane keep assist activation. Overall, while the MG4 offers great value for the money, these software and minor design issues detract from the experience.
