Mitsubishi 3000 MOT Failures
An analysis of 2,770 real DVSA MOT tests on the Mitsubishi 3000 — what fails, how often, and how that compares to every other car on UK roads. Generations covered: Z16A (1990–2000).
Where the Mitsubishi 3000 fails its MOT
The single biggest MOT failure point on the Mitsubishi 3000 is structural corrosion — this model is 20 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 2,770 MOT tests, 12.57% of all Mitsubishi 3000 tests recorded this as a failure.
Bodywork failures usually mean structural corrosion — not cosmetic rust, but rot that affects the car's structural integrity. Check sills, subframes, and chassis rails carefully, especially on older examples.
Other notable weak points include transmission shaft bearing worn (122x the fleet average), abs fault (11x the fleet average), subframe bushes or mounts worn (20x the fleet average), and emissions failure (11x the fleet average). These ratios compare the Mitsubishi 3000's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 5 categories: Bodywork, Suspension, Exhaust & Emissions, Seatbelts & Airbags, Brakes. If you're inspecting a Mitsubishi 3000 before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Mitsubishi 3000's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Mitsubishi 3000 specifically, the DVSA data shows the most common failures at this mileage are transmission shaft bearing worn (122x the average) and structural corrosion (12x). emissions failure (11x) and abs fault (11x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Mitsubishi 3000 specifically, the DVSA data shows the most common failures at this mileage are transmission shaft bearing worn (87x the average) and subframe bushes or mounts worn (20x). structural corrosion (20x) and seat mounting fault (11x) also appear frequently.

Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Mitsubishi 3000 specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Subframe mounting point corrosion (Z16A) Dangerous
The steel subframe mounting points in the body shell are prone to corrosion that weakens the load-bearing structure around suspension component mounting areas. Affects Z16A; typical independent garage repair cost is £800–£1,500.
Brake pipe corrosion (Z16A) Dangerous
Brake pipes on this model are prone to corrosion, failing at 4.8x the national fleet average according to MOT data. Affects Z16A; typical independent garage repair cost is £300–£600.
Transmission shaft bearing wear (Z16A) Major
The transmission output shaft bearings on this model are prone to excessive wear, particularly on higher mileage examples. Affects Z16A; typical independent garage repair cost is £1,500–£2,500.
Suspension component corrosion (Z16A) Major
Suspension components on this model suffer from corrosion damage at 8.3x the national fleet average, with the trend worsening. Affects Z16A; typical independent garage repair cost is £400–£800.

What to check before buying a Mitsubishi 3000
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Mitsubishi 3000:
Bodywork — check for structural corrosion, transmission shaft bearing worn. Suspension — check for abs fault, subframe bushes or mounts worn, suspension component damaged or corroded.
Beyond the MOT items, ask specifically about subframe mounting point corrosion and brake pipe corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £800. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
