MG3 reliability

MOT tests in 2025, published 22 Jun 2026. DVSA publishes a new year each summer.

75.0% of the 24,674 MG3 cars three years and over tested in 2025 passed their MOT first time. Cars of the same ages passed 80.9% of the time, so the MG3 did worse than average.

That ranks it 210 of 248 models overall and 3 of 3 MG models. How the score works.
