Every Mercedes-Benz Gle 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 Gle:

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 a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age. On a 2015 Mercedes-Benz Gle the average at test was 77,351 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 2020 at 90.5%, and the weakest in our data is 2017 at 87%. That 3.5 point spread across the model's life is why comparing a 2015 car against a newer one tells you very little.
