Every Mercedes-Benz G-Class model year
Pass rates fall as cars age, so the only fair comparison for a 2017 car is other cars of the same age. The full run for the Mercedes-Benz G-Class:
| Year | Pass rate | Tests | Avg mileage |
|---|---|---|---|
| 2017 | 82.3% | 231 | 41,847 |

What this means if you are buying a 2017 G-Class
The 2017 is a weaker year for this model, passing 3.1 points less often than the Mercedes-Benz G-Class average. Some of that is simply age, so compare it against the 2017 figure for all cars above rather than against newer examples. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.
What a 9-year-old car fails on
A 2017 car is 9 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:
- Lights and electrical: 10.36% of all cars tested
- Suspension: 8.65% of all cars tested
- Tyres: 6.23% of all cars tested
- Brakes: 6.1% of all cars tested
- Visibility: wipers, washers, glass: 4.65% of all cars tested
- Body, chassis and structure: 3.18% of all cars tested
That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck. On a 2017 Mercedes-Benz G-Class the average at test was 41,847 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.
The strongest year for this model is 2018 at 88.9%, and the weakest in our data is 2017 at 82.3%. That 6.6 point spread across the model's life is why comparing a 2017 car against a newer one tells you very little.
