Should I check the MOT history before buying a 2022 Mercedes Benz G 400 Amg Line Prem + D 4m A?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

This G 400 has a first-time MOT pass rate of just 57.1%, well below the UK average of 80%, which is a genuine red flag for a premium diesel SUV. The dangerous defect rate sits at a modest 1.2%, so catastrophic failures are rare, but the gap between this car and typical vehicles suggests underlying issues worth investigating before purchase.

At 25,197 median miles for a 2022 model, these cars are running relatively low mileage, yet they're still failing MOTs at nearly double the national rate—pointing to build or design gremlins rather than wear-and-tear problems. With an average of 0.07 failures per vehicle, the issues are real but scattered across the fleet; get a pre-purchase inspection focused on diesel emissions systems and suspension components, as these are common weak points on the G-Class platform.
