Top issues to watch for

The most serious Mitsubishi 3000 problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Subframe mounting point corrosion (Z16A)
Z16A1990–200060k–120k miles
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.
What happens if ignoredSubframe 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.

Dangerous
Brake pipe corrosion (Z16A)
Z16A1990–200060k–120k miles
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.
What happens if ignoredBrake 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.

Major
Transmission shaft bearing wear (Z16A)
Z16A1990–200080k–100k miles
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.
What happens if ignoredComplete 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.

Major
Suspension component corrosion (Z16A)
Z16A1990–200080k–100k miles
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.
What happens if ignoredSeverely 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.
