Renault Megane 2019: reliability & common MOT faults

In 2025, 77 in every 100 first MOTs on a 2019 Renault Megane were passes. Most common reason for a fail: Tyre condition (front).

Summary

The 2019 Renault Megane follows the pattern of the model years either side.

What failed most often

  1. Tyre condition (front)12 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 2019 Renault Megane 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.

Suspension

Three faults. The strongest is the anti-roll bar ball joint dust cover (front): 25 times as often as on similar cars.

Figures below are measured across the 552 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.

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 ball joint dust cover (front)

Failed on 26 first tests25 times as often as similar carsPossible evidence

What it means

A missing anti-roll bar ball joint dust cover is Major, and so is one that no longer prevents the ingress of dirt. A cover that is only severely deteriorated is Minor. DVSA uses one wording for the dust cover on any suspension joint.

Anti-roll bar linkage ball joint dust cover (front)

Failed on 48 first tests19 times as often as similar carsLikely evidence

What it means

A suspension joint dust cover that is severely deteriorated is Minor. It becomes Major once it is missing or no longer prevents the ingress of dirt, so what matters is whether it still keeps dirt out. DVSA words this for any suspension joint dust cover, and files it here under anti-roll bars.

Suspension arm ball joint (front)

Failed on 30 first tests2.8 times as often as similar carsPossible evidence

What it means

A suspension arm ball joint is failed under the general suspension pin, bush or joint wording. Excessively worn is Major, and likely to become detached is graded Dangerous.

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

Lamps and electrical

One fault: headlight (front), 3.2 times as often as on similar cars.

Headlight (front)

Failed on 48 first tests3.2 times as often as similar carsLikely evidence

What it means

On vehicles first used on or after a set date, a halogen headlamp unit converted to take HID or LED bulbs fails for light source and lamp not compatible, which is Major. A complete unit built with those light sources is not failed for that. The precise position of the lamps is not part of the inspection beyond a visual look to see that they sit at about the same height and distance from each side.

MOT pass rates

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

Did not pass, and were not fixed at the test station.

First-attempt pass 76.6% of 2,357 first tests (2025): only cars that passed first time count. Official-style pass 80.9%: cars fixed at the test station also count as a pass. The 4 fixed and the 19 not fixed make the 23 in every 100 that did not pass first time.

Petrol and diesel

Figures are in every 100 first tests. Cars with more miles usually fail more often, so the same-mileage figure gives every fuel the mileage mix of all the cars in this year.

If you are buying one

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

Mileage matters most on a 2019 Megane.

Of 2019 Megane vehicles with under 29,000 miles, 84 in every 100 passed their 2025 MOT first time. With 65,000 miles or more, 72 in every 100 did.

Petrol or diesel?

Typical mileagePassed first time,
as tested		Passed first time,
same mileage
Petrol38,256 miles7877
Diesel66,055 miles7377

Figures are in every 100 first tests. Petrol cars look better on the raw figures only because diesel cars have done more miles (typically 66,055 against 38,256). 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.

The 2019 Renault Megane follows the pattern of the model years either side. Its main cause of failure was Tyre condition (front), about 12 in every 100 failed tests. In 2025, 76.6% of 2,357 first MOTs on the 2019 Renault Megane passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 80.9%. Among 552 failed first-attempt MOT tests (test year 2025), Anti-roll bar ball joint dust cover (front) appears more often than on similar cars (4.7% of those tests; 26 observed failures; about 25× 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 2019 Renault Megane at the first attempt were Tyre condition (front) (12.3%), 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: Anti-roll bar ball joint dust cover (front) (4.7% of those tests; 26 observed failures; about 25× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Anti-roll bar ball joint dust cover (front) shows up more often than on similar cars (4.7% of those tests; 26 observed failures; about 25× 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 2019 Renault Megane include Anti-roll bar ball joint dust cover (front), Anti-roll bar linkage ball joint dust cover (front), Headlight (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.
This page highlights MOT failure patterns for the 2019 Renault Megane (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.
