Isuzu Rodeo 2011: reliability & common MOT faults

In 2025, 57 in every 100 first MOTs on a 2011 Isuzu Rodeo were passes.

Summary

With 621 first tests, there are too few to say whether the 2011 Isuzu Rodeo differs from the model years either side. Treat the faults below as a checklist.

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 Isuzu Rodeo 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.

Suspension

Three faults. The strongest is the leaf spring (rear): 27 times as often as on similar cars.

Figures below are measured across the 267 of 268 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.

Leaf spring (rear)

Failed on 21 first tests27 times as often as similar carsPossible evidence

What it means

Modified spring anchor or shackle brackets with more mounting holes than the chassis are not a reason to reject leaf spring suspension, and neither is a missing bump stop rubber. A fractured main leaf is graded Dangerous. A spring that is fractured or seriously weakened is graded Major.

Wheel bearings (front)

Failed on 21 first tests5.8 times as often as similar carsPossible evidence

What it means

Excessive play in a wheel bearing, or a bearing that is excessively rough, is Major. Play so excessive that the bearing is likely to break up or directional control is impaired is Dangerous, and so is a bearing so rough that it is likely to overheat or break up.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 63 first tests, 23 times as often as on similar cars.

Shock absorbers (rear)

Failed on 27 first tests3.5 times as often as similar carsPossible evidence

What it means

Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 23 first tests, 2.6 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.

Lamps and electrical

Two faults. The strongest is the rear fog light: 7.9 times as often as on similar cars.

Rear fog light

Failed on 28 first tests7.9 times as often as similar carsPossible evidence

What it means

A missing obligatory rear fog lamp, one that is not working, or one that does not emit a steady red light is graded Major. A rear fog lamp adversely affected by the operation of any other lamp is Major too. The manual allows it to go out when main beam is switched on or when dipped beam headlamps are switched off.

Headlight

Failed on 24 first tests2.2 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.

Seat belts and restraints

One fault: airbag warning light, 5.8 times as often as on similar cars.

Airbag warning light

Failed on 27 first tests5.8 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.

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
57in every 100
Passed on the first test.
Fixed at the station
7in every 100
Failed, then fixed at the test station the same day.
Failed
36in every 100
Did not pass, and were not fixed at the test station.

First-attempt pass 56.8% of 621 first tests (2025): only cars that passed first time count. Official-style pass 63.6%: cars fixed at the test station also count as a pass. The 7 fixed and the 36 not fixed make the 43 in every 100 that did not pass first time.

Same model, other years

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

FAQs

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

With 621 first tests, there are too few to say whether the 2011 Isuzu Rodeo differs from the model years either side. Treat the faults below as a checklist. In 2025, 56.8% of 621 first MOTs on the 2011 Isuzu Rodeo passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 63.6%. Among 268 failed first-attempt MOT tests (test year 2025), Leaf spring (rear) appears more often than on similar cars (7.9% of those tests; 21 observed failures; about 27× 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.
Among failed first-attempt tests we highlight patterns that appear more often than on similar cars. Top example: Leaf spring (rear) (7.9% of those tests; 21 observed failures; about 27× more often than similar cars). These are statistical signals, not a diagnosis of any individual car.
Leaf spring (rear) shows up more often than on similar cars (7.9% of those tests; 21 observed failures; about 27× 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 Isuzu Rodeo include Leaf spring (rear), Rear fog light, Wheel bearings (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 Isuzu Rodeo (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.
