2022 MG ZS Trophy EV Electric · CJ22 AEB

The most recent MOT, carried out on 17 July 2026, resulted in a dangerous failure because the nearside front tyre tread depth fell below the statutory minimum of 1.6 mm. The previous test, also on 17 July 2026, had recorded a pass, but the subsequent failure indicates a rapid deterioration in tyre condition. Over the past year the record shows a progression from advisory warnings about tyre wear and a nail in the nearside front tyre to an outright dangerous defect, signalling a worsening maintenance trend that the seller must have addressed promptly or the vehicle will remain unroadworthy. At 54 427 miles the MG ZS Trophy EV is approximately four years old, giving an average annual mileage of roughly 13 600 mi. This is well above the typical UK average of 8‑10 000 mi per year for a vehicle of this age, suggesting a higher level of component wear. The elevated mileage accelerates the consumption of tyre tread, brake pad and disc material, suspension bushings, and the high‑voltage battery’s charge‑cycle count, while also increasing the likelihood of corrosion in any parts that have spent extended periods idle between journeys. Prospective buyers should give the tyre set the highest priority. The nearside front tyre must be replaced immediately; the presence of a nail and sub‑minimum tread depth also raises the risk of a rapid puncture or loss of grip, which would manifest as a wobble, vibration or reduced braking efficiency, especially in wet conditions. The off‑side rear tyre, flagged as close to the legal limit, should be measured for tread depth and sidewall integrity; any cracking, dry rot or uneven wear patterns could indicate mis‑alignment or worn suspension components. A thorough visual inspection of all four tyres, checking for age‑related perishing (cracking of the sidewalls after more than six years regardless of tread depth), is essential, and the buyer should confirm that the vehicle’s tyre age code does not exceed the recommended service life. Beyond the tyres, the high mileage on an electric model warrants a check of the high‑voltage battery health via a diagnostic scan to verify state‑of‑charge capacity and any degradation that could affect range. The 12‑volt auxiliary battery should be load‑tested, as frequent short trips can weaken it. Inspect the suspension for loosened or cracked rubber bushings, especially on the front coil‑spring assemblies, and listen for clunks or excessive play when applying steering inputs. Examine the brake discs for surface rust, scoring or glazing, and ensure the pads have sufficient thickness; any pulsation or shudder under braking would point to warped discs or uneven pad wear. Finally, confirm that the coolant for the electric drivetrain and the brake fluid have been serviced within the manufacturer‑specified intervals, as time‑based fluid breakdown can lead to reduced cooling efficiency or corrosion in the hydraulic system. A test drive that includes steady acceleration, gentle braking, and a brief high‑speed run will reveal most of these potential issues before purchase.
