  2. Brake light11 in every 100 failed tests
  3. Handbrake efficiency below minimum (roller test)11 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 2010 Hyundai i30 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.

Suspension

Three faults. The strongest is the anti-roll bar linkage ball joints (rear): 15 times as often as on similar cars.

Figures below are measured across the 4,236 of 4,247 failed first attempts (99.7%) 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.

Anti-roll bar linkage ball joints (rear)

Failed on 212 first tests15 times as often as similar carsStrong evidence

What it means

Excessive wear on an anti-roll bar linkage ball joint is Major. A joint likely to become detached is graded Dangerous.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 283 first tests, 12 times as often as on similar cars.

Suspension arm (rear)

Failed on 320 first tests8.7 times as often as similar carsStrong evidence

What it means

A missing bump stop rubber is not a reason to fail a suspension arm. A component that is fractured, missing or likely to fail is graded Dangerous, and one excessively damaged or corroded is Major. On some vehicles, some highly stressed parts are thin pressed steel, and many of those have hollow box sections or up-facing areas that can collect road dirt and salt, so they get special attention.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 562 first tests, 4.8 times as often as on similar cars.

Suspension arm ball joint dust cover (front)

Failed on 192 first tests2.1 times as often as similar carsPossible evidence

What it means

Whether a suspension arm ball joint dust cover still keeps dirt out decides its grade. Severely deteriorated is Minor, while missing, or no longer preventing the ingress of dirt, is Major.

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

Steering

One fault: steering rack play, 14 times as often as on similar cars.

Steering rack play

Failed on 88 first tests14 times as often as similar carsLikely evidence

What it means

Excessive free play at the steering wheel rim, with a steering rack fitted, is Major, and Dangerous where the play is excessive to the extent that safe steering is affected. Play from wear or maladjustment must not be confused with apparent play from the way the mechanism is built, such as flexible joints.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 244 first tests, 12 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.

Brakes

Two faults and one wear pattern. The strongest is the handbrake lever: 3.6 times as often as on similar cars.

Handbrake lever

Failed on 128 first tests3.6 times as often as similar carsLikely evidence

What it means

A parking brake lever pivot or ratchet mechanism that is obviously worn is graded Minor. It is Major when worn to the extent that the brake may inadvertently release, and also when the ratchet is not holding correctly. A lever must have obvious excessive travel before being rejected.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 23 first tests, 4.6 times as often as on similar cars.

Brake discs (rear)

Failed on 135 first tests2.7 times as often as similar carsWear pattern

What it means

A brake disc or drum must be significantly worn before it is rejected, and being worn below the manufacturer's recommended limits is not a reason in itself. Significantly and obviously worn is Major, as is contamination with oil or grease. A disc or drum that is fractured, insecure, seriously weakened or missing is graded Dangerous.

Handbrake performance (roller test)

Failed on 99 first tests2.2 times as often as similar carsPossible evidence

What it means

A parking brake that is inoperative on one side is Major. When tested on the road, the failure is the vehicle deviating excessively from a straight line. Vehicles whose parking brake was already tested as the secondary brake are not tested again for this.

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

Lamps and electrical

One fault: brake light (rear), 2.3 times as often as on similar cars.

Brake light (rear)

Failed on 482 first tests2.3 times as often as similar carsPossible evidence

What it means

All stop lamps missing or not working is graded Dangerous, and so is a stop lamp that stays on when the brakes are released. A stop lamp that is missing or not working is Major. On some vehicles with LED rear lamps, part of the stop lamp can go out when the rear fog lamp is lit, which is not regarded as a defect.

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

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 2010 Hyundai i30 follows the pattern of the model years either side. Its main cause of failure was Individual sidelight or tail light (front), about 16 in every 100 failed tests. In 2025, 51.7% of 8,802 first MOTs on the 2010 Hyundai i30 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 61.6%. Among 4,247 failed first-attempt MOT tests (test year 2025), Anti-roll bar linkage ball joints (rear) appears more often than on similar cars (5.0% of those tests; 212 observed failures; about 15× 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 2010 Hyundai i30 at the first attempt were Individual sidelight or tail light (front) (15.6%), Brake light (11.4%) and Handbrake efficiency below minimum (roller test) (10.5%), 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: Anti-roll bar linkage ball joints (rear) (5.0% of those tests; 212 observed failures; about 15× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Anti-roll bar linkage ball joints (rear) shows up more often than on similar cars (5.0% of those tests; 212 observed failures; about 15× 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 2010 Hyundai i30 include Anti-roll bar linkage ball joints (rear), Suspension arm (rear), Steering rack play. 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 2010 Hyundai i30 (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.
