Toyota Yaris 2000: reliability & common MOT faults

In 2025, 55 in every 100 first MOTs on a 2000 Toyota Yaris were passes. Most common reason for a fail: Suspension mounting area (rear).

Summary

The 2000 Toyota Yaris follows the pattern of the model years either side.

What failed most often

  1. Suspension mounting area (rear)20 in every 100 failed tests
  2. Petrol emissions (with catalyst)10 in every 100 failed tests
  3. Individual sidelight or tail light (front)8 in every 100 failed tests

How we count this. Data: UK MOT open data, 2025. Only Class 4 cars on their first MOT of the year are counted. A car that fails and is fixed at the test station still counts as a fail in the first-attempt rate. These are raw results, not adjusted for age, mileage, or peer mix. The MOT does not test engine or gearbox internals.

Note:

These are patterns across 2000 Toyota Yaris vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.

Noise, emissions and leaks

One fault: petrol engine warning light, 11 times as often as on similar cars.

Figures below are measured across the 1,217 of 1,218 failed first attempts (99.9%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like.

We only list faults with at least 20 failures and a rate of about 2.0 times that of similar cars, which keeps one-off results out of the list.

Petrol engine warning light

Failed on 82 first tests11 times as often as similar carsLikely evidence

What it means

The malfunction indicator lamp (MIL) on a petrol engine is a Major failure when it is illuminated indicating a malfunction. The detail line DVSA gives for the same row also names an inoperative lamp. The test covers only certain petrol vehicles, depending on their age, size and fuel type.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Suspension

Five faults. The strongest is the anti-roll bar linkage pins and bushes (front): 9.0 times as often as on similar cars.

Anti-roll bar linkage pins and bushes (front)

Failed on 91 first tests9.0 times as often as similar carsLikely evidence

What it means

Excessive wear in an anti-roll bar linkage pin or bush is Major. If the pin or bush is likely to become detached, it is graded Dangerous. The wording is DVSA's general one for a suspension pin, bush or joint.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 220 first tests, 10 times as often as on similar cars.

Coil spring (rear)

Failed on 94 first tests6.2 times as often as similar carsLikely evidence

What it means

A missing bump stop rubber is not a reason to fail a coil spring. When the vehicle is jacked and lowered, a spring that does not correctly locate as the suspension returns to its normal running position is rejected as insecurely attached. A missing spring is Major, and graded Dangerous where directional control is affected.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 273 first tests, 4.7 times as often as on similar cars.

Shock absorbers (rear)

Failed on 67 first tests2.5 times as often as similar carsPossible evidence

What it means

Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 112 first tests, 2.7 times as often as on similar cars.

Suspension mounting area (rear)

Failed on 242 first tests2.4 times as often as similar carsPossible evidence

What it means

The load bearing structure within a set distance of a sub-frame, spring or suspension component mounting is a prescribed area. Major applies when its strength or continuity is significantly reduced or it is inadequately repaired. Dangerous applies when it is so weakened that control of the vehicle is likely to be adversely affected.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 134 first tests, 2.9 times as often as on similar cars.

Wheel bearings (rear)

Failed on 39 first tests2.1 times as often as similar carsPossible evidence

What it means

Excessive play in a wheel bearing, or a bearing that is excessively rough, is Major. Play so excessive that the bearing is likely to break up or directional control is impaired is Dangerous, and so is a bearing so rough that it is likely to overheat or break up.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Tyres

One wear pattern: tyre tread depth (front), 3.3 times as often as on similar cars.

Tyre tread depth (front)

Failed on 71 first tests3.3 times as often as similar carsWear pattern

What it means

Only primary grooves count when tread depth is assessed: those holding the wear indicators, or cut as deep as those when new. Shallower secondary grooves are ignored. Tread depth below the minimum for the vehicle is Dangerous, and so is a pattern not visible over the whole tread, but that second row applies only to vehicles that need the lower minimum.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.

Brakes

One wear pattern: brake pads (front), 2.6 times as often as on similar cars.

Brake pads (front)

Failed on 39 first tests2.6 times as often as similar carsWear pattern

What it means

A pad worn down to its wear indicator, or contaminated with oil or grease, is Major. A pad worn below the set thickness limit, missing or incorrectly mounted is Dangerous. The manual treats an illuminated brake wear indicator as no reason for failure, although DVSA also lists an illuminated indicator as a Major row.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 63 first tests, 2.0 times as often as on similar cars.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

Advisories

Other things testers noted as worn or close to failing, more often than on similar cars.

An advisory is a note from the tester about something that has not failed yet. It is an early warning, not a fail. Advisories for the faults above are shown with those faults.

Every figure here is a first-attempt MOT rate from DVSA open data for this model line, for cars of this model year tested in 2025. Each mileage band holds a fifth of the tests. MOTs do not test engine or gearbox internals, so this is a pre-purchase checklist, not a full reliability score.

FAQs

Short answers about how to read this model-year guide.

The 2000 Toyota Yaris follows the pattern of the model years either side. Its main cause of failure was Suspension mounting area (rear), about 20 in every 100 failed tests. In 2025, 54.7% of 2,689 first MOTs on the 2000 Toyota Yaris passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 63.1%. Among 1,218 failed first-attempt MOT tests (test year 2025), Petrol engine warning light appears more often than on similar cars (6.7% of those tests; 82 observed failures; about 11× more often than similar cars). There is no single reliability score here; this is a pre-purchase checklist built from DVSA open data, not a guarantee for any individual car.
Ranked by how often they were actually recorded, the items that most often failed a 2000 Toyota Yaris at the first attempt were Suspension mounting area (rear) (19.9%), Petrol emissions (with catalyst) (10.1%) and Individual sidelight or tail light (front) (8.4%), each as a share of the year's failed first attempts. That is what goes wrong most often on the car. The common faults table shows a different measure: faults that are unusual compared with similar cars.
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Petrol engine warning light (6.7% of those tests; 82 observed failures; about 11× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Petrol engine warning light shows up more often than on similar cars (6.7% of those tests; 82 observed failures; about 11× more often than similar cars). That does not prove a design fault. Age, mileage, and how the car was used still matter. Treat it as a pre-purchase checkpoint, not a manufacturer service bulletin.
Common MOT problem areas for the 2000 Toyota Yaris include Petrol engine warning light, Anti-roll bar linkage pins and bushes (front), Coil spring (rear). These are the faults that stand out compared with similar cars, not a complete list of what can go wrong on any individual car.
Advisories flag issues noted at the test and are not a fail rate. We show advisory patterns that appear more often than on similar cars among failed first-attempt tests, separate from common failure rows. Use them as early-warning checks, not as a pass/fail score.
This page highlights MOT failure patterns for the 2000 Toyota Yaris (registration year) using UK DVSA open data for the selected test year. Patterns are compared with cars of a similar age and mileage. It is a buyer checklist from MOT defect statistics, not a full service history or manufacturer service-bulletin list.
No. MOT tests do not cover engine internals, gearboxes, or many electronic modules. Patterns here come from MOT defect statistics only and should not be read as engine or gearbox reliability scores.

About this data

How this page is built and what it can (and can't) say.

These figures come from UK MOT open data for this model year. We surface common failure patterns against similar cars, not a full reliability score, and not a pass/fail verdict on any individual vehicle.

2024 2025

What we include

UK Class 4 cars only. Normal MOT tests (not retests); first test per vehicle per calendar year; results pass, PRS, or fail.

Same-day repairs

PRS means the car failed items that were fixed at the test station and then passed the same day. We count PRS as a first-attempt fail in headline rates so same-day repairs do not hide problems.

How we compare

We compare this model year with other Class 4 cars of similar age and mileage in the same test year. This model family is left out of the peer group so the car is not measured against itself.

What this does not cover

  • MOTs do not cover engine internals, gearboxes, or many electronics; this is not a full reliability score.
  • Common faults come from MOT defect stats, not manufacturer TSBs or recalls.
  • Age and mileage matching reduces, but does not remove, differences in how cars were used and maintained.
  • If the data for a car is too thin to say anything useful, we say so rather than guess.
