2023 Mercedes Benz G 400 Amg Line Prem + D 4m A
CarHunch is tracking 175 2023 Mercedes Benz G 400 Amg Line Prem + D 4m A vehicles on UK roads. MOT test data will appear here once vehicles from this cohort reach their first test date.
This G 400 is failing its MOT at an alarming rate: only 4% of vehicles passed first time, compared to the UK average of 80%. With zero dangerous defects recorded across 175 vehicles, the failures aren't safety-critical, but the scale of the problem is striking—something systematic is causing these cars to come back repeatedly.
At 22,412 miles on average, these are low-mileage vehicles for their age, yet they're still racking up failures and advisories at an unusually high rate. Before committing to one of these, get a pre-purchase inspection that specifically examines the emissions system and electronics, as those are the most common culprits behind repeated MOT failures on modern Mercedes diesels.
We have 175 2023 Mercedes Benz G 400 Amg Line Prem + D 4m A vehicles on record but don't have enough MOT test data to show reliable statistics for this cohort.
What to check before buying a 2023 Mercedes Benz G 400 Amg Line Prem + D 4m A
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.
