Hyundai Coupe 2006: reliability & common MOT faults

In 2025, 52 in every 100 first MOTs on a 2006 Hyundai Coupe were passes. Most common reason for a fail: Handbrake efficiency below minimum (roller test).

Summary

With 689 first tests, there are too few to say whether the 2006 Hyundai Coupe differs from the model years either side.

What failed most often

  1. Handbrake efficiency below minimum (roller test)34 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 2006 Hyundai Coupe 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.

Brakes

Two faults. The strongest is the handbrake efficiency below minimum (roller test): 4.7 times as often as on similar cars.

Figures below are measured across the 332 of 333 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.

Handbrake efficiency below minimum (roller test)

Failed on 113 first tests4.7 times as often as similar carsLikely evidence

What it means

A parking brake with efficiency below the minimum requirement is Major, and graded Dangerous where efficiency is less than half of the required value. On a roller brake tester, the requirement counts as met if more than half of the wheels of a brake system lock. The check applies only to vehicles whose parking brake was not already tested as the secondary brake.

Anti-lock braking system (ABS)

Failed on 29 first tests3.9 times as often as similar carsPossible evidence

What it means

ABS is failed as removed only where it has obviously been removed, because not every vehicle in the age range where removal is not permitted has ABS. A warning lamp that does not light or shows an ABS fault is Major, as is a missing or excessively damaged wheel speed sensor. Every failure row for this component is Major.

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

Body and structure

One fault: exhaust system (rear), 3.2 times as often as on similar cars.

Exhaust system (rear)

Failed on 23 first tests3.2 times as often as similar carsPossible evidence

What it means

Exhaust fumes causing a danger to health of persons on board are graded Dangerous, and so is a silencer likely to become detached. Fumes entering the cabin are Major. One or more missing or defective mountings does not necessarily make the exhaust insecure, since testers assess the overall security of the system.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 29 first tests, 2.8 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.

Noise, emissions and leaks

One fault: petrol emissions (with catalyst), 2.5 times as often as on similar cars.

Petrol emissions (with catalyst)

Failed on 44 first tests2.5 times as often as similar carsPossible evidence

What it means

Emissions levels over the manufacturer's specified limits are Major, as are levels over default limits, which apply when no exact match is found for the vehicle. Dense blue or clearly visible black smoke at idle, held for a set period, is Major, except for certain older vehicles and two stroke engines where smoke is unavoidable. An induction or exhaust leak that could affect emissions levels is Major too.

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.

MOT pass rates

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

Passed first time
52in 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
40in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 51.7% of 689 first tests (2025): only cars that passed first time count. Official-style pass 60.2%: cars fixed at the test station also count as a pass. The 8 fixed and the 40 not fixed make the 48 in every 100 that did not pass first time.

Same model, other years

Passed first time in every 100, all tested in 2025.

FAQs

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

With 689 first tests, there are too few to say whether the 2006 Hyundai Coupe differs from the model years either side. Its main cause of failure was Handbrake efficiency below minimum (roller test), about 34 in every 100 failed tests. In 2025, 51.7% of 689 first MOTs on the 2006 Hyundai Coupe passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 60.2%. Among 333 failed first-attempt MOT tests (test year 2025), Handbrake efficiency below minimum (roller test) appears more often than on similar cars (34.0% of those tests; 113 observed failures; about 4.7× 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 2006 Hyundai Coupe at the first attempt were Handbrake efficiency below minimum (roller test) (34.0%), 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: Handbrake efficiency below minimum (roller test) (34.0% of those tests; 113 observed failures; about 4.7× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Handbrake efficiency below minimum (roller test) shows up more often than on similar cars (34.0% of those tests; 113 observed failures; about 4.7× 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 2006 Hyundai Coupe include Handbrake efficiency below minimum (roller test), Anti-lock braking system (ABS), Exhaust system (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 2006 Hyundai Coupe (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.
