2023 MG HS Exclusive PHEV Auto

CarHunch analysed 1,249 real MOT records for the 2023 MG HS Exclusive PHEV Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2023 MG HS is a serious red flag: only 15.9% pass on first attempt against the UK average of 80%, meaning four out of five fail their MOT. The good news is dangerous defects are rare at 0.4%, but the sheer failure rate suggests systemic quality issues with this model year.

At 31,889 miles average for a 2023 model, these cars haven't even reached typical three-year service intervals, yet they're already struggling with MOT compliance. With an average of 0.03 failures and 0.2 advisories per vehicle, the problems appear minor and scattered rather than one catastrophic flaw—but that wide failure rate indicates a pattern of small defects across the fleet. If you're considering this model, budget for multiple repair attempts before passing MOT, and request a full pre-purchase inspection with specific focus on emissions and electrical systems.

What to check before buying a 2023 MG HS Exclusive PHEV Auto

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
