Expert verdict
Brakes: 3.0× the national share
Brakes make up 62.5% of everything recorded on the 2025 Toyota Prius, against 20.9% nationally — 41.6 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- When it fails, it costs. Only 33% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.
- Based on a small sample. 168 tests back this page. That is enough to publish and to index, not enough to treat the decimal places as precise — read the pattern, not the second digit.

What fails a 2025 Prius
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2025 Prius
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the lights 1.2% of tests
“rear fog lamp not working”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
-
Check the number plates 1.2% of tests
“registration plates does not conform to the specified requirements”
Check both plates are present, legible and correctly spaced, with the postcode of the supplier and the BS AU 145e mark. A private plate in the wrong style is a fail before the car is even looked at.
-
Check the suspension joints 0.6% of tests
“ball joint dust cover severely deteriorated”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.

What testers noted without failing the car
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.
| Recorded item | Severity | Tests | Est. cost |
|---|---|---|---|
| Brake discs in such a condition that it is seriously weakened Brakes | Advisory | 9.5% | £45–110 |
| Brake discs significantly and obviously worn Brakes | Advisory | 8.3% | £45–110 |
| Tread depth tread pattern not visible over the whole tread area when minimum depth required is 1.0mm Tyres | Advisory | 2.4% | £45–95 |
| Has a tear, caused by separation or partial failure of its structure Tyres | Advisory | 1.8% | £45–95 |
| Tread depth below requirements of 1.6mm Tyres | Advisory | 1.8% | £45–95 |
| Non-component advisories Play in steering rack inner joint(s) Non-component advisories | Advisory | 0.60% | £120–300 |
