Every Mercedes-Benz Viano model year

Pass rates fall as cars age, so the only fair comparison for a 2011 car is other cars of the same age. The full run for the Mercedes-Benz Viano:

What a 15-year-old car fails on

A 2011 car is 15 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 very high mileage. Clutches, dual-mass flywheels and head gaskets have usually been through at least one repair by this point, so ask for evidence rather than assume the car is original everywhere. On a 2011 Mercedes-Benz Viano the average at test was 158,354 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 2014 at 76.2%, and the weakest in our data is 2006 at 65%. That 11.2 point spread across the model's life is why comparing a 2011 car against a newer one tells you very little.
