Hyundai i20 2009: reliability & common MOT faults

In 2025, 56 in every 100 first MOTs on a 2009 Hyundai i20 were passes. Most common reason for a fail: Individual sidelight or tail light (front).

Summary

A 2009 Hyundai i20 passed first time about 3 in every 100 less often than the 2010 model year next to it.

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 2009 Hyundai i20 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 macpherson strut (front): 5.6 times as often as on similar cars.

Figures below are measured across the 3,504 of 3,507 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.

Macpherson strut (front)

Failed on 120 first tests5.6 times as often as similar carsStrong evidence

What it means

Many MacPherson strut top bushes are designed to have significant lateral play when the suspension hangs free, so a top bush is rejected only when the play comes from wear or maladjustment. A top bush or bearing with excessive wear or free play is Major. Rubber or synthetic bushes are rejected only for serious deterioration of the bonding or flexible material.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 63 first tests, 2.1 times as often as on similar cars.

Suspension arm ball joint dust cover (front)

Failed on 216 first tests2.7 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.

Anti-roll bar linkage ball joints (front)

Failed on 228 first tests2.1 times as often as similar carsPossible 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.

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

Seat belts and restraints

One fault: airbag warning light, 4.4 times as often as on similar cars.

Airbag warning light

Failed on 232 first tests4.4 times as often as similar carsLikely evidence

What it means

The airbag warning lamp (SRS MIL in DVSA's wording) is failed only if it indicates a system malfunction, which is Major. A lamp lit to show the passenger airbag is disabled is not to be regarded as a defect. Dashboard messages are not a defect in their own right, though they can help the tester confirm a malfunction.

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

Lamps and electrical

One fault: side repeater indicators, 2.4 times as often as on similar cars.

Side repeater indicators

Failed on 126 first tests2.4 times as often as similar carsPossible 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.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 100 first tests, 13 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

Three faults and one wear pattern. The strongest is the handbrake lever: 2.3 times as often as on similar cars.

Handbrake lever

Failed on 71 first tests2.3 times as often as similar carsPossible 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.

Brake imbalance across an axle (roller test, efficiency check, rear)

Failed on 97 first tests2.1 times as often as similar carsPossible evidence

What it means

A wheel giving less than a set share of the maximum effort from the other wheel on the same axle is Major. On a steered axle, less than half is graded Dangerous. Testers disregard an imbalance if the lower effort is the result of a locked wheel, or if the higher effort from a wheel is at or below a low set figure.

Brake discs (rear)

Failed on 71 first tests2.1 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.

Rigid brake pipes (rear)

Failed on 130 first tests2.0 times as often as similar carsPossible evidence

What it means

Chafing, corrosion or damage to a rigid brake pipe justifies rejection once its wall thickness is reduced by a set amount, although DVSA accepts this is not easy to determine. If a tester is not sure, the benefit of the doubt applies. A leaking pipe or connection is graded Dangerous on a hydraulic system and Major on an air system.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 525 first tests, 3.1 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.

If you are buying one

What this year's MOT record means for the decision in front of you.

Mileage matters most on a 2009 Hyundai i20.

Of 2009 Hyundai i20 vehicles with under 55,000 miles, 69 in every 100 passed their 2025 MOT first time. With 112,000 miles or more, 50 in every 100 did.

Petrol or diesel?

Typical mileagePassed first time,
as tested		Passed first time,
same mileage
Petrol81,920 miles5757
Diesel98,472 miles5457

Figures are in every 100 first tests. Petrol cars look better on the raw figures only because diesel cars have done more miles (typically 98,472 against 81,920). At the same mileage there is no clear difference between the two.

What to check at your mileage

How often each fault turned up on a failed first test, by the car's mileage. Read it as: what is likely to need looking at on a car like the one in front of you.

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.

A 2009 Hyundai i20 passed first time about 3 in every 100 less often than the 2010 model year next to it. In 2025, 56.5% of 8,062 first MOTs on the 2009 Hyundai i20 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 67.5%. Among 3,507 failed first-attempt MOT tests (test year 2025), Macpherson strut (front) appears more often than on similar cars (3.4% of those tests; 120 observed failures; about 5.6× 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 2009 Hyundai i20 at the first attempt were Individual sidelight or tail light (front) (21.6%), Brake light (10.5%) and Windscreen washers (7.7%), 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: Macpherson strut (front) (3.4% of those tests; 120 observed failures; about 5.6× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Macpherson strut (front) shows up more often than on similar cars (3.4% of those tests; 120 observed failures; about 5.6× 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 2009 Hyundai i20 include Macpherson strut (front), Airbag warning light, Suspension arm ball joint dust cover (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 2009 Hyundai i20 (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.
