Where the MG Zs Exclusive Ev fails its MOT

Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include excessive wear or play in a universal joint or ... (18x the fleet average), lens defective (17x the fleet average), seat mounting fault (8.9x the fleet average), and stop lamp missing, inoperative or in the case o... (5.3x the fleet average). These ratios compare the MG Zs Exclusive Ev's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.

How failures change with mileage
The MG Zs Exclusive Ev's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the MG Zs Exclusive Ev specifically, the DVSA data shows the most common failures at this mileage are excessive wear or play in a universal joint or ... (18x the average) and headlight fault (18x). lens defective (17x) and seat mounting fault (8.9x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
The standout failure at this mileage is stop lamp missing, inoperative or in the case o... at 5.3x the fleet average.
The shift from excessive wear or play in a universal joint or ... at lower mileages to stop lamp missing, inoperative or in the case o... at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
