What a 12-year-old car fails on

A 2014 car is 12 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 above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures. On a 2014 Mercedes-Benz Gl the average at test was 88,730 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.

2014 is the strongest year on record for this model at 86.8%, ahead of every other year we hold data for.
