What a 17-year-old car fails on

A 2009 car is 17 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 2009 Daihatsu Sirion the average at test was 69,832 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.

2009 is the strongest year on record for this model at 71.3%, ahead of every other year we hold data for.
