2023 Mercedes Benz Eqs 450+ Amg Line Premium +

CarHunch analysed 113 real MOT records for the 2023 Mercedes Benz Eqs 450+ Amg Line Premium +. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This Mercedes-Benz EQS 450+ is failing MOT at an alarming rate—just 27.9% pass first time versus the UK average of 80%—and while dangerous defects are rare at 0.9%, the sheer volume of failures suggests systemic issues with this model at this age. Most owners are encountering problems that need fixing before they can pass, rather than one-off components going wrong.

With an average mileage of just 23,154 miles, these are nearly-new vehicles racking up serious MOT issues early in their life, pointing to design or build quality problems rather than wear-and-tear. If you're considering this model, budget for immediate remedial work before purchase, and have an independent specialist inspect the vehicle's electrical and brake systems—the most common culprits on early-failure Mercedes—rather than relying on an MOT pass alone.

What to check before buying a 2023 Mercedes Benz Eqs 450+ Amg Line Premium +

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.
