Every Mazda 6 model year
Pass rates fall as cars age, so the only fair comparison for a 2017 car is other cars of the same age. The full run for the Mazda 6:

What this means if you are buying a 2017 6
The 2017 is one of the stronger years for this model, passing 10 points more often than the Mazda 6 average. That is a point in its favour, though condition and service history still matter more than the model year.

What a 9-year-old car fails on
A 2017 car is 9 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 2017 Mazda 6 the average at test was 68,845 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 2020 at 92.8%, and the weakest in our data is 2004 at 57.8%. That 35.0 point spread across the model's life is why comparing a 2017 car against a newer one tells you very little.
