Which year to buy? →
The 2015 G-Class is more reliable than average, with an 88.3% first-time pass rate comfortably ahead of the UK's 80%, and dangerous defects affecting only 14.2% of the cohort—well below the concern threshold. Petrol variants perform consistently well at 88.8%, suggesting the powertrain is fundamentally sound.
These cars are running relatively low mileage for their age at just over 40,600 miles on average, which helps explain the strong pass rate, though you'll still see an average of 1.01 failures per test. The 5.2 advisories per vehicle point to routine maintenance items rather than structural problems, so budget for regular servicing but don't expect major surprises—check service history carefully when viewing one, as that's your best predictor of how the next few years will go.
