Chevrolet Aveo 2011: reliability & common MOT faults

In 2025, 50 in every 100 first MOTs on a 2011 Chevrolet Aveo were passes. Most common reason for a fail: Individual sidelight or tail light (front).

Summary

With 894 first tests, there are too few to say whether the 2011 Chevrolet Aveo differs from the model years either side.

  2. Suspension arm pins and bushes (front)14 in every 100 failed tests
  3. Track rod end (front)14 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 2011 Chevrolet Aveo 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.

Seat belts and restraints

One fault: airbag warning light, 5.0 times as often as on similar cars.

Figures below are measured across the 443 of 445 failed first attempts (99.6%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like.

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.

Airbag warning light

Failed on 25 first tests5.0 times as often as similar carsPossible evidence

What it means

The airbag warning lamp (SRS MIL in DVSA's wording) is failed only if it indicates a system malfunction, which is Major. A lamp lit to show the passenger airbag is disabled is not to be regarded as a defect. Dashboard messages are not a defect in their own right, though they can help the tester confirm a malfunction.

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

Brakes

Three faults. The strongest is the anti-lock braking system (ABS): 4.7 times as often as on similar cars.

Anti-lock braking system (ABS)

Failed on 29 first tests4.7 times as often as similar carsPossible evidence

What it means

ABS is failed as removed only where it has obviously been removed, because not every vehicle in the age range where removal is not permitted has ABS. A warning lamp that does not light or shows an ABS fault is Major, as is a missing or excessively damaged wheel speed sensor. Every failure row for this component is Major.

Brake performance (roller test, front)

Failed on 32 first tests4.2 times as often as similar carsLikely evidence

What it means

A wheel with no recorded braking effort on the roller test is graded Dangerous. Inadequate effort, a brake grabbing severely, abnormal lag and excessive fluctuation in effort are each Major. So is significant brake effort recorded with no brake applied, which indicates a binding brake.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 23 first tests, 2.9 times as often as on similar cars.

Rigid brake pipes (rear)

Failed on 27 first tests3.8 times as often as similar carsPossible 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 65 first tests, 3.6 times as often as on similar cars.

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

Steering

One fault: track rod end (front), 3.5 times as often as on similar cars.

Track rod end (front)

Failed on 60 first tests3.5 times as often as similar carsLikely evidence

What it means

A steering ball joint with excessive wear or free play is Major, and one worn to the extent there is a serious risk of detachment is graded Dangerous. A dust cover that is damaged but still keeps dirt out is Minor, and one missing or no longer keeping dirt out is Major. Testers must tell wear from a joint's built-in clearance or spring loading.

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

Suspension

Two faults. The strongest is the suspension arm pins and bushes (front): 3.1 times as often as on similar cars.

Suspension arm pins and bushes (front)

Failed on 63 first tests3.1 times as often as similar carsLikely evidence

What it means

Pins and bushes on suspension arms fail as Major when they are excessively worn. They are graded Dangerous when likely to become detached. DVSA uses the same wording for a suspension joint.

Anti-roll bar linkage ball joints (front)

Failed on 23 first tests2.2 times as often as similar carsPossible evidence

What it means

Excessive wear on an anti-roll bar linkage ball joint is Major. A joint likely to become detached is graded Dangerous.

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

Noise, emissions and leaks

One fault: petrol engine warning light, 2.1 times as often as on similar cars.

Petrol engine warning light

Failed on 25 first tests2.1 times as often as similar carsPossible evidence

What it means

The malfunction indicator lamp (MIL) on a petrol engine is a Major failure when it is illuminated indicating a malfunction. The detail line DVSA gives for the same row also names an inoperative lamp. The test covers only certain petrol vehicles, depending on their age, size and fuel type.

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
50in every 100
Passed on the first test.
Fixed at the station
9in every 100
Failed, then fixed at the test station the same day.
Failed
41in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 50.2% of 894 first tests (2025): only cars that passed first time count. Official-style pass 58.9%: cars fixed at the test station also count as a pass. The 9 fixed and the 41 not fixed make the 50 in every 100 that did not pass first time.

Same model, other years

FAQs

Short answers about how to read this model-year guide.

With 894 first tests, there are too few to say whether the 2011 Chevrolet Aveo differs from the model years either side. Its main cause of failure was Individual sidelight or tail light (front), about 16 in every 100 failed tests. In 2025, 50.2% of 894 first MOTs on the 2011 Chevrolet Aveo passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 58.9%. Among 445 failed first-attempt MOT tests (test year 2025), Airbag warning light appears more often than on similar cars (5.6% of those tests; 25 observed failures; about 5.0× 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 2011 Chevrolet Aveo at the first attempt were Individual sidelight or tail light (front) (16.0%), Suspension arm pins and bushes (front) (14.2%) and Track rod end (front) (13.5%), 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: Airbag warning light (5.6% of those tests; 25 observed failures; about 5.0× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Airbag warning light shows up more often than on similar cars (5.6% of those tests; 25 observed failures; about 5.0× 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 2011 Chevrolet Aveo include Airbag warning light, Anti-lock braking system (ABS), Brake performance (roller test, 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.
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 2011 Chevrolet Aveo (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.
