What a 6-year-old car fails on
A 2020 car is 6 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 below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck. On a 2020 Mercedes-Benz Gla 220 Amg Line Prem D 4m A the average at test was 30,761 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.
2020 is the strongest year on record for this model at 94%, ahead of every other year we hold data for.
