Suzuki Baleno 2017: reliability & common MOT faults

In 2025, 71 in every 100 first MOTs on a 2017 Suzuki Baleno were passes. Most common reason for a fail: Suspension arm ball joint dust cover (front).

Summary

The 2017 Suzuki Baleno follows the pattern of the model years either side.

  2. Tyre tread depth (rear)10 in every 100 failed tests
  3. Horn10 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 2017 Suzuki Baleno 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

Two faults. The strongest is the horn: 20 times as often as on similar cars.

Figures below are measured across the 605 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.

Horn

Failed on 59 first tests20 times as often as similar carsLikely evidence

What it means

A horn that does not work, or is likely to be confused with an emergency vehicle siren, is graded Major. Gongs, bells, sirens and anything with more than one tone, which includes a horn that alternates between its notes, are not allowed, except a gong, bell or siren on vehicles first used before a set date. Sound defects are Minor for named cases such as a bell or harsh sound, and Major under a general row.

Number plate lights

Failed on 20 first tests2.0 times as often as similar carsPossible evidence

What it means

Registration plate lamps must light up the rear registration plate and operate at the same time as the position lamps. A missing or inoperative lamp is Major when the plate has only one lamp or all its lamps are not working, and Minor when the plate has several lamps or light sources and not all have failed. A lamp throwing direct white light to the rear is also Minor.

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

Suspension

One fault: suspension arm ball joint dust cover (front), 17 times as often as on similar cars.

Suspension arm ball joint dust cover (front)

Failed on 188 first tests17 times as often as similar carsStrong 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.

Brakes

Two faults. The strongest is the rigid brake pipes (rear): 16 times as often as on similar cars.

Rigid brake pipes (rear)

Failed on 41 first tests16 times as often as similar carsLikely 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 82 first tests, 13 times as often as on similar cars.

Handbrake efficiency below minimum (roller test)

Failed on 32 first tests2.6 times as often as similar carsPossible 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.

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

Tyres

One wear pattern: tyre tread depth (rear), 3.6 times as often as on similar cars.

Tyre tread depth (rear)

Failed on 61 first tests3.6 times as often as similar carsWear pattern

What it means

Only primary grooves count when tread depth is assessed: those holding the wear indicators, or cut as deep as those when new. Shallower secondary grooves are ignored. Tread depth below the minimum for the vehicle is Dangerous, and so is a pattern not visible over the whole tread, but that second row applies only to vehicles that need the lower minimum.

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
71in every 100
Passed on the first test.
Fixed at the station
4in every 100
Failed, then fixed at the test station the same day.
Failed
25in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 71.3% of 2,108 first tests (2025): only cars that passed first time count. Official-style pass 75.4%: cars fixed at the test station also count as a pass. The 4 fixed and the 25 not fixed make the 29 in every 100 that did not pass first time.

Same model, other years

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

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 2017 Suzuki Baleno follows the pattern of the model years either side. Its main cause of failure was Suspension arm ball joint dust cover (front), about 31 in every 100 failed tests. In 2025, 71.3% of 2,108 first MOTs on the 2017 Suzuki Baleno passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 75.4%. Among 605 failed first-attempt MOT tests (test year 2025), Suspension arm ball joint dust cover (front) appears more often than on similar cars (31.1% of those tests; 188 observed failures; about 17× 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 2017 Suzuki Baleno at the first attempt were Suspension arm ball joint dust cover (front) (31.1%), Tyre tread depth (rear) (10.1%) and Horn (9.8%), 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: Suspension arm ball joint dust cover (front) (31.1% of those tests; 188 observed failures; about 17× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Suspension arm ball joint dust cover (front) shows up more often than on similar cars (31.1% of those tests; 188 observed failures; about 17× 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 2017 Suzuki Baleno include Suspension arm ball joint dust cover (front), Horn, Rigid brake pipes (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 2017 Suzuki Baleno (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.
