Every Lexus Is model year
Pass rates fall as cars age, so the only fair comparison for a 2013 car is other cars of the same age. The full run for the Lexus Is:
| Year | Pass rate | Tests | Avg mileage |
|---|---|---|---|
| 2013 | 84.4% | 410 | 95,781 |
| 2014 | 88% | 3,052 | 97,185 |
| 2015 | 89.7% | 2,813 | 88,029 |
| 2016 | 89.8% | 1,984 | 79,238 |
| 2017 | 92.2% | 1,548 | 63,840 |
| 2018 | 92.8% | 1,455 | 58,230 |
| 2019 | 92.4% | 1,156 | 50,215 |
| 2020 | 93.4% | 561 | 37,900 |
What this means if you are buying a 2013 Is
The 2013 is a weaker year for this model, passing 5.7 points less often than the Lexus Is average. Some of that is simply age, so compare it against the 2013 figure for all cars above rather than against newer examples. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.
What a 13-year-old car fails on
A 2013 car is 13 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 and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust. On a 2013 Lexus Is the average at test was 95,781 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 93.4%, and the weakest in our data is 2013 at 84.4%. That 9.0 point spread across the model's life is why comparing a 2013 car against a newer one tells you very little.
