Toyota Aygo MOT pass rate & common failures
1,428,093 MOT tests on the Toyota Aygo (2005–2025) give it an 84.7% pass rate. That is 2.1 percentage points better than city cars of a similar age, which fail at 17.4%. Its most common failure areas are lighting & signalling, brakes and tyres.
Best and worst Aygo years
Ranked across Aygo years with at least 1,000 tests. Older cars fail more simply because they are older — compare years close together in age before drawing conclusions.
What the MOT record shows
Build year matters more than the headline suggests: 2022 cars pass 96.2% of the time while 2005 cars manage 69.2%, a 26.9-point spread.
No single area dominates — lighting & signalling (8.3%) and brakes (6.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, service brake performance and tread depth — headlamp aim alone was recorded 50,343 times.
Condition tracks the odometer closely. Failures run at 6.7% in the 0-30k band and 30.6% in the 150k+ band, a 23.8-point spread — more than double.
The petrol cars hold up better: 15.3% fail against 29.3% for diesel, a 14.0-point gap across 1,428,037 tests.
Tyres is the most common advisory, noted on 25.1% of tests — work that passed today but is likely due soon.

What to check before buying a Toyota Aygo
- Lighting & signalling (8.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (6.3% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Tyres (4.6% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
