Vauxhall Corsa 2017: reliability & common MOT faults

15,917 first-attempt MOT failures were recorded on the 2017 Vauxhall Corsa in 2025. The items recorded most often on them were Track rod end (front) and Coil spring (front). Figures are among first-attempt failed MOT tests, not among all tests.

Diesel Corsas passed first time 2.0 pp more often than petrol ones (70.1% of 2,087 vs 68.1% of 47,875).

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 15,914 of 15,917 failed first attempts that recorded an odometer reading in 2025 — the subset the age-and-mileage comparison can be computed on.

Standout: Track rod end (front) — 24.9% of this year's failed first attempts

Recorded on 3,955 of those tests. It tops the table on elevation — about 11× 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
Track rod end (front)
Steering > Steering linkage components > Track rod end
 Front 3,955 ×11 24.9% Strong
Electronic stability control
Brakes > ABS / EBS / ESC > Electronic stability control
 Any 993 ×10 6.2% Strong
Coil spring (front)
Suspension > Springs > Coil springs > Coil spring
 Front 3,238 ×4.5 20.3% Likely

Shock absorbers (front)

 Front 796 ×3.4 5.0% 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.

If you are buying one

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

On this year, prefer the diesel. The petrol cars passed first time 2.0 pp less often, on 47,875 tests.

This year also sits 1.4 pp below the midpoint of the 2016 and 2018 cars either side of it — a real break in the model's own run, not the usual year-on-year drift.

Other Corsa 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
2020 Corsa +3.6 pp better 84.7% 43,640
2015 Corsa +1.7 pp better 63.2% 83,121
2019 Corsa +1.5 pp better 80.1% 51,441
2013 Corsa +1.4 pp better 58.1% 66,425
2014 Corsa -4.0 pp worse 56.7% 69,021
2021 Corsa -3.2 pp worse 82.0% 38,722
2018 Corsa -1.5 pp worse 72.7% 51,156

What to check on a 2017 Corsa

The items that failed 2017 Corsas 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.

  • Track rod end (front) — recorded on 24.9% of failed first attempts
  • Coil spring (front) — recorded on 20.3% of failed first attempts
  • Malfunction indicator lamp — recorded on 8.8% of failed first attempts
  • Tread depth (front) — recorded on 6.3% of failed first attempts
  • Electronic stability control — recorded on 6.2% 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.

Diesel Corsas passed first time 2.0 pp more often than petrol ones (70.1% of 2,087 vs 68.1% of 47,875). In 2025, 68.1% of 49,963 first MOTs on the 2017 Vauxhall Corsa passed first time (PRS — items fixed at the station the same day — counted as a fail). The official-style rate including PRS is 72.9%. Among 15,917 failed first-attempt MOT tests (test year 2025), Track rod end (front) appears more often than on simila…
Ranked by how often they were actually recorded, the items that failed 2017 Vauxhall Corsas most often at the first attempt were Track rod end (front) (24.9%), Coil spring (front) (20.3%) and Malfunction indicator lamp (8.8%) — 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, which the common-faults tabl…
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Track rod end (front) (24.9% of those tests; 3,955 observed failures; about 11× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Track rod end (front) shows up more often than on similar cars (24.9% of those tests; 3,955 observed failures; about 11× 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 Corsa include Track rod end (front), Electronic stability control, Coil spring (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 Corsa (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.
