Toyota Yaris 2013: reliability & common MOT faults

In 2025, 69 in every 100 first MOTs on a 2013 Toyota Yaris were passes. Most common reason for a fail: Coil spring (front).

Summary

At the same mileage, a hybrid 2013 Toyota Yaris passed first time more often than a petrol one: 74 in every 100 against 67 in every 100.

What failed most often

  2. Individual sidelight or tail light (front)19 in every 100 failed tests
  3. Windscreen washers7 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 2013 Toyota Yaris vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.

Lamps and electrical

Two faults. The strongest is the side repeater indicators (front): 4.6 times as often as on similar cars.

Figures below are measured across the 8,838 of 8,842 failed first attempts 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.

Side repeater indicators (front)

Failed on 547 first tests4.6 times as often as similar carsLikely evidence

What it means

Sequential or dynamic direction indicators are not a reason to fail. Where a side repeater is required, it is allowed to be part of the front direction indicator if it has a marked wraparound lens, or an amber light coming through the front lens when viewed from a set distance to the side of the rear bumper. A lens defect with no effect on the emitted light is Minor, and one that adversely affects the light is Major.

Individual sidelight or tail light (front)

Failed on 1,653 first tests2.5 times as often as similar carsPossible evidence

What it means

A position lamp showing red light to the front or white light to the rear is Major. Rear lamps must show a steady red light, and front ones can show white, predominantly white with a blue tinge, or yellow if combined in a yellow headlamp. With a multiple light source, up to half not working is Minor and more than half is Major.

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

Suspension

One fault: coil spring (front), 3.5 times as often as on similar cars.

Coil spring (front)

Failed on 2,380 first tests3.5 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.

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.

MOT pass rates

How first tests ended, and how the pass rates are counted.

Passed first time
69in every 100
Passed on the first test.
Fixed at the station
8in every 100
Failed, then fixed at the test station the same day.
Failed
23in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 68.6% of 28,189 first tests (2025): only cars that passed first time count. Official-style pass 76.8%: cars fixed at the test station also count as a pass. The 8 fixed and the 23 not fixed make the 31 in every 100 that did not pass first time.

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.

At the same mileage, a hybrid 2013 Toyota Yaris passed first time more often than a petrol one: 74 in every 100 against 67 in every 100. In 2025, 68.6% of 28,189 first MOTs on the 2013 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 76.8%. Among 8,842 failed first-attempt MOT tests (test year 2025), Side repeater indicators (front) appears more often than on similar cars (6.2% of those tests; 547 observed failures; about 4.6× 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 2013 Toyota Yaris at the first attempt were Coil spring (front) (26.9%), Individual sidelight or tail light (front) (18.7%) and Windscreen washers (7.3%), 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: Side repeater indicators (front) (6.2% of those tests; 547 observed failures; about 4.6× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Side repeater indicators (front) shows up more often than on similar cars (6.2% of those tests; 547 observed failures; about 4.6× 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 2013 Toyota Yaris include Side repeater indicators (front), Coil spring (front), Individual sidelight or tail light (front). 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 2013 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.
