Every Mercedes-Benz GT model year

Pass rates fall as cars age, so the only fair comparison for a 2015 car is other cars of the same age. The full run for the Mercedes-Benz GT:

What an 11-year-old car fails on

A 2015 car is 11 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 low mileage, which usually means light urban use. Short journeys are harder on batteries, brakes and exhausts than motorway miles, so do not assume low miles means low wear. On a 2015 Mercedes-Benz GT the average at test was 29,941 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 2017 at 96.1%, and the weakest in our data is 2019 at 91.5%. That 4.6 point spread across the model's life is why comparing a 2015 car against a newer one tells you very little.
