2023 MG 4 Trophy Electric · FD23 TWM

The 2023 MG 4 Trophy’s latest MOT test on 2026-06-19 resulted in a failure due to a critical offside rear tyre defect—specifically, a cut exceeding the legal limits that penetrated the tyre’s ply or cords, which is a severe safety hazard requiring immediate replacement. Despite this failure, the same test also issued an advisory for near-side front suspension arm pin or bush wear, noted as “not resulting in excessive movement but starting to split,” indicating early-stage deterioration in a critical suspension component. While the vehicle passed the initial inspection, the recurring advisory suggests a developing issue that, if left unaddressed, could escalate into a major failure, particularly given the proximity of the tyre failure. The trend in the MOT history is concerning, as it reflects either a poorly maintained vehicle or a design flaw in the suspension or tyre retention systems that has not been adequately addressed between tests. The buyer should prioritise addressing these defects promptly to prevent further degradation and ensure roadworthiness. The recorded mileage of 30,064 miles for a vehicle aged just over three years represents a reasonable annual usage rate of approximately 10,021 miles, which is within the expected range for a car of this age and class. However, the consistency of mileage accumulation—without apparent long periods of inactivity—may imply either regular, heavy use or a tendency to drive frequently, both of which can accelerate wear on consumables, suspension components, and drivetrain elements. The absence of significant mileage gaps suggests the vehicle has been in active service, which could contribute to the observed suspension and tyre wear patterns. Buyers should be aware that such usage patterns may necessitate more frequent maintenance checks, particularly for items like suspension bushings, tyres, and brake systems, where wear can progress more rapidly under higher mileage regimes. Given the critical tyre failure and the advisory on suspension arm pin/bush wear, the buyer must undertake immediate and thorough inspections to confirm the severity of these issues. For the offside rear tyre, the cut reaching the ply or cords is a red flag; the tyre must be replaced without delay, as further damage could compromise tyre integrity and increase the risk of a blowout. During a test drive, listen for any unusual suspension noises, such as clunks or rattles, which could indicate further wear in the front suspension arms or bushes. Check for uneven tyre wear patterns, which may suggest misalignment or suspension issues, and inspect the vehicle’s alignment settings to ensure they are correct. The near-side front suspension arm pin or bush wear should be addressed as soon as possible, as excessive movement or splitting could lead to steering instability or suspension failure. If the vehicle has been driven frequently, the suspension components may already be under stress, and further inspection by a qualified mechanic is strongly advised to assess the extent of damage. In addition to the immediate concerns, the buyer should conduct a comprehensive physical inspection of the vehicle to identify any secondary issues that may have arisen from the reported defects or from the vehicle’s usage profile. Focus on the rear tyre’s condition, ensuring there are no additional cuts, bulges, or signs of tread separation that could indicate further tyre degradation. Inspect the suspension for any signs of corrosion, particularly around the suspension arms and mounting points, as prolonged exposure to moisture can accelerate rusting, especially in areas that are not easily accessible. Check the brake system for signs of corrosion on the discs or binding calipers, which can occur if the vehicle has been left stationary for extended periods. Verify the fluid levels in the cooling system, brake fluid reservoir, and power steering reservoir, as these fluids degrade over time and can lead to system failure if not serviced regularly. Finally, examine the tyre sidewalls for signs of age-related perishing, such as cracking or dry rot, which can compromise tyre safety even if the tread appears serviceable. A thorough inspection of the battery terminals and condition should also be performed, as a failing battery can lead to electrical issues or even a complete failure if left unchecked. If the vehicle has been driven at a moderate pace, the wear on components like the engine mounts, exhaust system, and exhaust emissions components should be minimal, but a visual check for leaks or unusual noises during acceleration is prudent.
