What a 5-year-old car fails on
A 2021 car is 5 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 low mileage, which usually means light urban use. Short journeys are harder on batteries, brakes and exhausts than motorway miles, so do not assume low miles means low wear. On a 2021 Porsche Taycan Turbo S the average at test was 20,796 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.
2021 is the strongest year on record for this model at 91.3%, ahead of every other year we hold data for.
