Every Mercedes-Benz Glc 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 Glc:

What this means if you are buying a 2015 Glc

The 2015 is a weaker year for this model, passing 4 points less often than the Mercedes-Benz Glc average. Some of that is simply age, so compare it against the 2015 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 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 Glc the average at test was 76,551 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 2021 at 93.1%, and the weakest in our data is 2015 at 84.2%. That 8.9 point spread across the model's life is why comparing a 2015 car against a newer one tells you very little.
