History & Generations

Z16A (1990–2000) — Engine options included the 3.0 V6. Our database flags 5 known issues on this generation, 2 of which are rated as safety-critical. The most significant concern is Subframe mounting point corrosion (£800–£1,500 to address).

5 Things to Know Before You Buy
1
Subframe mounting point corrosion
Critical £800–£1,500 Z16A

The steel subframe mounting points in the body shell are prone to corrosion that weakens the load-bearing structure around suspension component mounting areas. This affects the structural integrity of the car's handling and safety systems. The problem worsens with age and is particularly severe on UK cars due to road salt exposure.

Subframe detachment can cause complete loss of vehicle control and poses an immediate safety risk. Repair requires professional structural welding and MOT retest. Extensive corrosion may render the car uneconomical to repair if multiple mounting points are affected.

What to check

Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.

2
Brake pipe corrosion
Critical £300–£600 Z16A

Brake pipes on this model are prone to corrosion, failing at 4.8x the national fleet average according to MOT data. The trend is worsening, with 519 recorded failures across multiple mileage bands. Steel brake pipes are particularly vulnerable to UK road salt conditions, and failure represents an immediate safety hazard with potential for complete brake system failure.

Brake pipe failure can result in partial or complete loss of braking ability, creating an immediate and severe safety risk. The car should not be driven if brake pipe corrosion is suspected. Emergency repair may require professional recovery and immediate brake system replacement.

What to check

Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.

3
Transmission shaft bearing wear
High £1,500–£2,500 Z16A

The transmission output shaft bearings on this model are prone to excessive wear, particularly on higher mileage examples. MOT data shows this specific defect occurring at 122x the national fleet average between 80,000-100,000 miles. The failure rate is improving, suggesting remaining examples may have already been repaired or scrapped. This affects power transmission and can lead to complete drivetrain failure if not addressed.

Complete bearing failure will result in loss of power transmission and require transmission removal for repair. The car will be immobilised and require recovery. Repair typically involves transmission rebuild or replacement.

What to check

Listen for clunking or vibration from underneath when pulling away or changing direction. Check for play in the driveshafts by rocking the car in gear with the handbrake on. Worn CV boots are a telltale sign — look for grease splatter around the inner wheel arch.

4
Suspension component corrosion
High £400–£800 Z16A

Suspension components on this model suffer from corrosion damage at 8.3x the national fleet average, with the trend worsening. This typically affects control arms, subframes, and mounting brackets where road salt accelerates corrosion of the steel components. The failure rate is concentrated around 80,000-100,000 miles, suggesting age-related deterioration of protective coatings.

Severely corroded suspension components can fail suddenly, affecting vehicle control and safety. Worn components cause uneven tyre wear and poor handling. Repair may require multiple suspension component replacement depending on the extent of corrosion.

What to check

Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.

5
Lambda sensor failure
Minor £150–£300 Z16A

This affects the engine's ability to maintain correct fuel mixture, leading to poor fuel economy, rough running, and MOT emissions failures. The high failure rate suggests the sensors are particularly sensitive to fuel quality or operating conditions on this engine.

Failed lambda sensors cause poor fuel economy, rough running, and will result in MOT emissions failure. The engine may run rich or lean, potentially causing long-term engine damage or catalytic converter failure if not corrected promptly.

What to check

Check for any engine warning lights on the dashboard. Ask about the car's MOT emissions history — repeated failures suggest underlying issues. A pre-purchase diagnostic scan is especially worthwhile to check for stored emissions fault codes.

MOT Weak Points

Based on 2k real DVSA MOT tests, the Mitsubishi 3000 fails more often than average on several items. The biggest outlier is transmission shaft bearing worn at 122x the fleet average, followed by subframe bushes or mounts worn (20x).

When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Mitsubishi 3000 MOT failure breakdown for data at every mileage point.

Running Costs

Routine servicing (oil and filter change every 6k miles) typically costs £80–£120 at an independent garage.

The bigger-ticket items to budget for include timing belt (£400–£600).

See the full Mitsubishi 3000 service schedule for every interval and cost breakdown.

The Verdict

The Mitsubishi 3000 has some well-documented weak points, including 2 safety-critical issues that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable.

Before committing, check the car's full MOT history, verify the service record is complete, and if possible arrange a specialist inspection. Enter any registration into our free report to see the complete picture.
