21.1% of MG ZS models that failed an MOT failed the next one too, against 16.4% after a pass (2019–2024, n = 2,727). The failure most likely to come back is ‘lamps, reflectors and electrical equipment’: 25.4% of those fails recurred at the next MOT.

Of every 100 MG ZS models tested at age 5, about 20 failed the MOT first time; at age 7, about 27 (rough estimate). These are one-year rates for different cars tested in the same year, not a fleet followed over time; the steepest one-year step in this cross-section is between cars aged 4 and 5, 4.42 percentage points (2024).

In Norway, 28.0% of MG ZS models failed their periodic roadworthiness inspection, against 33.7% for all cars there (2024 by country, n = 5,051 inspections).
Both readings are shown: this comparison changes when usage or inspection rules differ.
Inspections abroad disagree: none point the same way as Britain, Norway and the Netherlands do not. Test rules, climate and how the vehicles are used differ, so both readings are shown.

How the MOT Risk Index and every figure on this page are calculated: methodology.
What is wrong on this page? One tap sends the category only, no text and nothing about you.
84.1% of first attempts passed in 2024 (44,212 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.
Other sites may count retests or all attempts. This page uses 44,212 primary tests: 15.92% failed first time and 87.4% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 117.4 is shown separately.
