2017 Toyota Auris — MOT failures & pass rate
78,019 MOT tests on the 2017 Toyota Auris are in this dataset, and 90.5% of them passed. Against small family cars of a similar age (11.9% fail rate), the 2017 Auris comes out 2.5pp better. Failures cluster in lighting & signalling, tyres and visibility.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 7.6% of tests against 4.5% for the next-worst category.
At component level the recurring items are stop lamp, wipers and headlamp — stop lamp alone was recorded 3,166 times.
Mileage is the strongest signal on the record: 5.0% of 0-30k cars fail, rising to 14.7% once past 150k — 2.9× the risk.
The petrol cars hold up better: 8.1% fail against 12.7% for diesel, a 4.6-point gap across 16,896 tests.
Tyres is the most common advisory, noted on 20.1% of tests — work that passed today but is likely due soon.
The trend is worsening — 6.3% of tests failed in 2021 against 11.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2017 Auris
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 7.6% of tests. Start there.
- Lighting & signalling (7.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (4.5% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Visibility (3.1% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
