Renault Kadjar 2019: reliability & common MOT faults

In 2025, 79 in every 100 first MOTs on a 2019 Renault Kadjar were passes. Most common reason for a fail: Tyre condition (front).

Summary

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

What failed most often

  1. Tyre condition (front)17 in every 100 failed tests
  2. Tyre tread depth (front)11 in every 100 failed tests
  3. Brake pads (front)9 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 Kadjar 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.

Lamps and electrical

One fault and one wear pattern. The strongest is the headlight aim not tested (front): 3.0 times as often as on similar cars.

Figures below are measured across the 2,345 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.

Headlight aim not tested (front)

Failed on 20 first tests3.0 times as often as similar carsWear pattern

What it means

Headlamp aim recorded as not tested, or unable to be tested, is a Major failure. These results must only be used where it becomes apparent during the test that the item cannot be tested, and this could not have been identified before starting. The reason must be included in the additional information box.

Headlight (front)

Failed on 141 first tests2.4 times as often as similar carsPossible 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.

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

Suspension

One fault: coil spring (rear), 2.0 times as often as on similar cars.

Coil spring (rear)

Failed on 107 first tests2.0 times as often as similar carsPossible 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.

Data: UK MOT open data, 2025. Counts cover advisories recorded on failed first tests only, compared with cars of the same age and mileage.

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 79.2% of 11,272 first tests (2025): only cars that passed first time count. Official-style pass 83.2%: cars fixed at the test station also count as a pass. The 4 fixed and the 17 not fixed make the 21 in every 100 that did not pass first time.

Petrol and diesel

Diesel1,47847,324 miles7981

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.

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 Kadjar follows the pattern of the model years either side. Its main cause of failure was Tyre condition (front), about 17 in every 100 failed tests. In 2025, 79.2% of 11,272 first MOTs on the 2019 Renault Kadjar passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 83.2%. Among 2,345 failed first-attempt MOT tests (test year 2025), Headlight (front) appears more often than on similar cars (6.0% of those tests; 141 observed failures; about 2.4× 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 Kadjar at the first attempt were Tyre condition (front) (17.3%), Tyre tread depth (front) (11.3%) and Brake pads (front) (9.3%), 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: Headlight (front) (6.0% of those tests; 141 observed failures; about 2.4× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Headlight (front) shows up more often than on similar cars (6.0% of those tests; 141 observed failures; about 2.4× 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 Kadjar include Headlight (front), Coil spring (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 2019 Renault Kadjar (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.
