Does high mileage mean more MG ZT MOT failures at the same age?

At ages 15+, 10.8% of MG ZTs with under 40,000 miles failed first time, against 40.9% of those with over 140,000 miles (2024, n = 638). Inside this age group, higher mileage goes with more failures.

If an MG ZT fails, does it fail again?

33.7% of MG ZTs that failed an MOT failed the next one too, against 32.9% after a pass (2019–2024, n = 1,750). The failure most likely to come back is visibility: 29.6% of those fails recurred at the next MOT.

Which MG ZT faults come together?

On MG ZTs, ‘body, chassis, structure’ and ‘noise, emissions and leaks’ failures turn up together 4.2 times as often as chance would predict (2024, n = 258).

What does an MG ZT cost to run in a fleet?

Of every 100 MG ZTs tested at age 18, about 39 failed the MOT first time (rough estimate); at age 19, about 36 (rough estimate). These are one-year rates for different cars tested in the same year, not a fleet followed over time (2024).

Does the month of an MG ZT MOT matter?

MG ZTs fail first time most in January (45.7%, against 31.1% for all cars that month) and least in May (38.3%) (2024, n = 2,239).

MG ZT MOT: quick answers

What is the MG ZT first-time MOT pass rate?

64.0% of first attempts passed in 2024 (2,239 tests). Retests after repair are excluded; cars fixed at the test centre (PRS) are shown separately.

Why does this number differ from other sites?

Other sites may count retests or all attempts. This page uses 2,239 primary tests: 35.95% failed first time and 69.0% passed when cars fixed at the test centre (PRS) count as passes. The age-adjusted MOT Risk Index 86.2 is shown separately.
