Note:

  • Class 4 cars · first MOT of the year per vehicle · P/PRS/F outcomes (2025 data).
  • PRS (fixed at the station the same day) counts as a fail in the first-attempt rate.
  • Raw outcomes for this cohort — not adjusted for age, mileage, or peer mix.
  • MOT doesn't test engine or gearbox internals.

Common faults

Failure patterns that show up more often on this registration year than on similar cars.

These MOT failure patterns show up more often on this registration year than on similar cars of the same class, age, and mileage.

Shares below are measured across the 1,815 failed first attempts in 2025 that the age-and-mileage comparison can be computed on.

Standout: Linkage ball joint dust cover (front) — 13.6% of this year's failed first attempts

Recorded on 247 of those tests. It tops the table on elevation — about 15× more often than on similar cars of the same age and mileage. On this year it is also the commonest failure, so it answers both questions at once. The full ranked list is in the table below.

Fault pattern Location Failures vs similar cars Share of fails Confidence
Linkage ball joint dust cover (front)
Suspension > Anti-roll bars > Linkage ball joint dust cover
 Front 247 ×15 13.6% Strong
Ball joint dust cover (front)
Suspension > Anti-roll bars > Ball joint dust cover
 Front 100 ×14 5.5% Strong
Exhaust system (front)
Body, chassis, structure > Exhaust system
 Front 90 ×9.9 5.0% Likely
Position lamp (front)
Lamps, reflectors and electrical equipment > Position lamps > Position lamp
 Front 104 ×3.5 5.7% Likely
Linkage ball joints (front)
Suspension > Anti-roll bars > Linkage ball joints
 Front 55 ×3.0 3.0% Likely

Only patterns that clear minimum sample and elevation thresholds are shown (at least 20 failures and about 2.0× more often than similar cars).

Note: Rates and comparisons are among first-attempt failed tests, not all MOTs. Patterns come from MOT defect codes — not manufacturer service bulletins, recalls, or a diagnosis of any individual car. Failures and advisories are listed separately.

Wear patterns

Usage and mileage effects that often track road use rather than model design.

These patterns look like wear or usage effects rather than model-specific design faults. Tyres, brake friction material, and alignment-related defects often track mileage and road use.

Pattern Location Failures vs similar cars Share of fails Confidence
Tyre pressure monitoring system
Tyres > Tyre pressure monitoring system
 Any 235 ×4.3 12.9% Wear
Note: These patterns are not treated as a model design fault in our common-faults ranking.

Advisories

Notes recorded at the test that appear more often than on similar cars.

Advisory notes recorded on failed first-attempt tests that appear more often than on similar cars.

Advisory pattern Location Notes vs similar cars Share Confidence
Exhaust system (front)
Body, chassis, structure > Exhaust system
 Front 180 ×12 9.9% Likely
Seat belts — Condition (rear)
Seat belts and supplementary restraint systems > Seat belts > Condition
 Rear 24 ×5.2 1.3% Elevated
Individual direction indicators (rear)
Lamps, reflectors and electrical equipment > Direction indicators > Flashing type > Individual direction indicators
 Rear 22 ×4.4 1.2% Elevated
Road Wheels — Condition (front)
Road Wheels > Condition
 Front 29 ×2.1 1.6% Elevated
Note: Advisories are not a fail rate — they flag issues noted at the test, often before they become failures.

If you are buying one

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

Nothing separates this year from the Vivas either side of it, so buy on the individual car. The checks below are the items that actually failed 2017 Vivas, commonest first.

Other Viva years worth knowing about

Newer cars always pass more often, so a plain "best year" list would just rank by age. These are the years that beat or miss the trend their own neighbouring years set — the only age-adjusted signal this data supports.

Year vs the years either side First-attempt pass (rises with newer cars) First tests
2018 Viva +1.6 pp better 84.4% 5,302
2015 Viva -3.3 pp worse 71.9% 4,952

What to check on a 2017 Viva

The items that failed 2017 Vivas most often, as a share of the year's failed first attempts. This is what goes wrong, not what is unusual — the table further up the page covers that.

  • Linkage ball joint dust cover (front) — recorded on 13.6% of failed first attempts
  • Tyre pressure monitoring system — recorded on 12.9% of failed first attempts
  • Tyres — Condition (rear) — recorded on 10.1% of failed first attempts
  • Visibility — Wipers (front) — recorded on 8.7% of failed first attempts
  • Tread depth (front) — recorded on 7.3% of failed first attempts

Every figure here is a first-attempt MOT rate from DVSA open data for this model line. 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.

Linkage ball joint dust cover (front) was the most common reason a 2017 Viva failed its MOT — 13.6% of its failed first attempts. In 2025, 80.7% of 9,422 first MOTs on the 2017 Vauxhall Viva passed first time (PRS — items fixed at the station the same day — counted as a fail). The official-style rate including PRS is 85.3%. Among 1,815 failed first-attempt MOT tests (test year 2025), Linkage ball joint dust cover (f…
Ranked by how often they were actually recorded, the items that failed 2017 Vauxhall Vivas most often at the first attempt were Linkage ball joint dust cover (front) (13.6%), Tyre pressure monitoring system (12.9%) and Tyres — Condition (rear) (10.1%) — each as a share of the year's failed first attempts. That is what goes wrong on the car. It is a different question from which patterns are unusual for the class, wh…
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Linkage ball joint dust cover (front) (13.6% of those tests; 247 observed failures; about 15× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Linkage ball joint dust cover (front) shows up more often than on similar cars (13.6% of those tests; 247 observed failures; about 15× 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 check point, not a manufacturer service bulletin.
Common MOT problem areas for the 2017 Vauxhall Viva include Linkage ball joint dust cover (front), Ball joint dust cover (front), Exhaust system (front). These patterns show up more often than on similar cars after we filter out sparse noise — not a full list of every possible fault on an 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 Vauxhall Viva (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.
  • We never invent pass rates, star scores, or ranks when those data marts are missing.
