Is the 1991 Mitsubishi Pajero reliable?

It can be very reliable when maintained, but at this age reliability depends heavily on service history, cooling system condition, and drivetrain fluid changes.

What are the most common 1991 Mitsubishi Pajero problems?

The most common issues include cooling system failures that can lead to overheating, automatic transmission shift problems on high-mileage examples, worn suspension/steering components, and oil leaks from aging gaskets and seals.

Are maintenance costs high for a 1991 Mitsubishi Pajero?

Costs are usually moderate for routine service, but can rise if you’re catching up on deferred items like suspension rebuilds, cooling system refresh, tires, and drivetrain seals. Parts availability varies by market.

What are the best years to buy for a classic Pajero like this?

The best years are typically the ones with the cleanest rust-free body and the best maintenance records, but many buyers prefer later first-generation or early second-generation examples for incremental updates and parts support in some regions.

What should I check before buying a 1991 Mitsubishi Pajero?

Check for overheating signs, transmission behavior, 4WD engagement in 4H and 4L, front-end looseness, fluid leaks, and rust in the frame/body areas common to your climate. A compression test and a full underbody inspection are smart.
