Mitsubishi Pajero Years to AvoidThe weakest years — and the one you should buy instead
After reviewing every Mitsubishi Pajero we've analyzed (23 years), these are the 4 weakest. Each one has either an absolute low reliability score, chronic repair issues, or unusually high ownership costs relative to other Pajero years.
Proceed with caution
1987 Mitsubishi Pajero
The 1987 Mitsubishi Pajero is a classic, rugged off-roader with a reputation for solid mechanicals, but its advanced age introduces significant maintenance considerations. While inherently robust, expect to commit to regular preventative work and potential repairs to address wear and tear, especially if considering an example from a rust-prone region. This is a capable and charming vehicle, but certainly not a 'set it and forget it' proposition.
Why this year scores low
The ladder frame, body mounts, wheel wells, rocker panels, and floor pans are highly susceptible to severe rust, often leading to structural compromise. This is exacerbated in regions with road salt or high humidity.
On 2.6L gasoline engines, the Mikuni carburetor is known for vacuum leaks, clogged jets, and overall wear, leading to poor idling, stalling, and reduced performance. Fuel lines are also prone to corrosion and leaks.
Rubber components throughout the suspension (leaf springs, control arms), steering, and driveshafts (U-joints, CV boots) deteriorate with age, leading to clunking, vibrations, and premature wear of other components. Transmission/transfer case seals can also leak.
Proceed with caution
1988 Mitsubishi Pajero
The 1988 Mitsubishi Pajero, a true off-road icon, stands as a testament to rugged 80s engineering; however, its age dictates that acquiring one requires careful inspection and a dedicated maintenance budget. While fundamentally robust, neglect will quickly expose its vulnerabilities. If you're seeking a capable, adventurous classic 4x4 and are prepared for the commitment, it can still deliver immense satisfaction.
Why this year scores low
Severe rust commonly affects frame rails, body mounts, wheel arches, rocker panels, and tailgate hinges. This compromises structural integrity and can make repairs difficult or impossible.
Rubber fuel lines degrade and crack, leading to leaks and potential fire hazards. Fuel pumps (both mechanical and electric) can fail, and fuel tanks are prone to internal corrosion and blockages.
Due to age and typical off-road use, components like ball joints, tie rod ends, idler arms, and suspension bushings are often severely worn, leading to sloppy handling, vibrations, and safety concerns.
Proceed with caution
1989 Mitsubishi Pajero
The 1989 Mitsubishi Pajero is a supremely capable and rugged off-roader, but its advanced age makes condition paramount for long-term ownership. While its mechanicals are generally robust, expect age-related wear and specific weaknesses like rust and diesel engine sensitivity to require proactive attention. This isn't a 'set it and forget it' vehicle, but a well-maintained example offers a classic and reliable adventure platform.
Why this year scores low
The ladder frame, body mounts, sills, wheel arches, and floor pans are highly susceptible to severe rust, especially in regions with road salt or high humidity. This can compromise structural integrity and make repairs difficult.
The 2.5L 4D56 turbo-diesel engine is prone to head gasket failure and cylinder head cracking if the cooling system is neglected or the engine is frequently overheated, often due to clogged radiators, failing water pumps, or worn fan clutches.
Aging wiring insulation, corroded grounds, and failing relays or switches can lead to intermittent issues with headlights, dashboard gauges, power windows, and starting circuits.
Proceed with caution
1990 Mitsubishi Pajero
The 1990 Mitsubishi Pajero is a rugged, capable off-roader, but its age makes proper pre-purchase inspection and a significant maintenance budget non-negotiable. While the underlying mechanicals are robust, expect to address common age-related issues, particularly rust and potential cooling system weaknesses on diesel variants, to ensure a dependable ownership experience.
Why this year scores low
The ladder frame, body mounts, wheel wells, sills, and rear crossmembers are highly susceptible to severe corrosion, especially in regions with road salt. This can compromise structural integrity and make repairs difficult.
The 2.5L 4D56 turbo-diesel engine is prone to cylinder head cracking or head gasket failure, often due to overheating from neglected cooling systems, blocked radiators, or faulty thermostats. This is a critical and costly repair.
Aging wiring harnesses, brittle insulation, corroded grounds, and failing relays lead to intermittent issues with lights, gauges, power windows, and starting. Diagnosis can be time-consuming.
