MG MG5 EV Common Problems & Reliability
The MG5 EV, launched in 2020, occupies a unique position as one of the few electric estate cars available in the UK. Positioned as a practical and value-focused alternative to electric crossovers, it offers a traditional low-slung silhouette that prioritizes aerodynamic efficiency and boot space. In the UK, it has become a staple for both high-mileage taxi operators and value-conscious families, prized for its generous 7-year warranty and a level of equipment that often surpasses its more expensive European rivals. Reliability for the MG5 has been generally good, reflecting MG’s focus on mechanical simplicity, but it does have specific "budget" themes to watch for. While the electric motor and battery are fundamentally robust, some owners have reported minor electrical glitches with the infotainment system and "wobbles" during rapid charging sessions. More significantly, the vehicle lacks extensive stone-chip protection on the inner bonnet and sills, making them prone to surface rust if not protected. Additionally, the driver’s seat bolsters are known to split or collapse prematurely on high-mileage examples used for commercial work. When buying a used MG5 EV in the UK, the priority is verifying that the 7-year/80,000-mile warranty remains valid via a full main-dealer service history. Prospective owners should carefully inspect the paintwork for stone chips and consider fitting aftermarket mudflaps to protect the sills from corrosion. It is also important to verify the battery's "State of Health" (SOH) and check for any software updates aimed at improving charging stability. For those seeking the best experience, the 2022-onwards "Long Range" facelift model is highly recommended, as it features significantly improved interior materials and more modern exterior styling.

Most Common MG MG5 EV Faults & Repair Costs
Rear Washer Pipe Detachment
The pipe for the rear washer can disconnect, causing water to leak into the cabin or near electrical components.
Rear washer not spraying, Damp smell in the boot, Wet carpets in the A-pillar area
12V Battery Drainage
Like many EVs, the 12V battery can fail or drain, preventing the car from entering "Ready" mode.
Car won't start, Random error messages, Keyless entry glitches
Front Tyre Wear
The MG5 is front-wheel drive with significant torque, leading to faster-than-expected front tyre wear. This is worse in Eco mode which can cause wheel spin on damp surfaces.
Front tyres wearing faster than rears, Uneven tread wear pattern, Reduced grip in wet conditions
Chrome Trim Corrosion
Some owners have reported surface rust developing on the shiny chrome trim pieces around the doors and windows, particularly on cars without mudflaps fitted.
Rust spots on chrome door trim, Orange staining on brightwork, Corrosion around window surrounds
Driver Seat Collapse
The driver's seat base foam and frame can collapse on higher-mileage cars, particularly those used as ex-fleet vehicles. This affects comfort and support.
Seat feeling "saggy", Reduced lateral support, Discomfort on long drives
