MG HS MOT failures and reliability
The MG HS is one of the stronger cars at the MOT: 89% of its 22,923 tests in 2025 were passed first time, 17 points better than the 72% for all cars. Half the MG HS cars tested were registered in 2022 or later, and younger cars pass more often. That ranks it 3rd of the 14 MG models we cover. Every figure here comes from the DVSA's record of each MG HS MOT, so it shows what testers found rather than what owners report.
