The automatic transmission of the Mitsubishi Pajero shows typical weak points, which manifest themselves in various symptoms. The transmission no longer shifts properly, does not jump into the desired gear or no longer functions fully. These frequent faults occur particularly in vehicles with high mileage, typically from 150,000 km, but can also occur earlier if insufficient maintenance is carried out. The reliability of the automatic transmission is heavily dependent on regular oil changes and the quality of the operating fluids used. The first signs are jerky gear changes, delayed gear engagement or slipping of the clutch. In the case of advanced damage, the gearbox can fail completely and the vehicle will come to a standstill.
A systematic check is essential for the early detection of transmission problems. The complex Mitsubishi Pajero automatic transmissions require special diagnostic equipment for fault reading and regular flushing of the transmission oil every 60,000 km. Repairs often involve replacing valve bodies, clutch packs or torque converters, and the cost can be considerable. Preventive maintenance through regular oil changes and the use of original transmission oil can significantly extend the service life and avoid expensive repairs.
The 3.2 DI-D engine of the Mitsubishi Pajero has characteristic weak points in the common rail injection system. These common faults are manifested by uneven engine running, loss of power and black smoke from the exhaust. The problems typically occur between 120,000 and 180,000 km, but can occur earlier if the fuel quality is poor or maintenance is irregular. The injectors become clogged with deposits, leading to uneven combustion. In addition, problems with the high-pressure pump can occur, affecting the entire injection system. Symptoms also include increased fuel consumption, starting difficulties when the engine is cold and the check engine light coming on.
Regular maintenance is critical to the longevity of the 3.2 DI-D system. The sensitive Mitsubishi Pajero injection components require high-quality fuel and regular cleaning with special additives every 15,000 km. Diagnosis is carried out by measuring the pressure in the common rail system and checking the injection nozzles on a test bench. In the event of problems, the injection nozzles often have to be overhauled or the high-pressure pump replaced. Preventive treatment with fuel system cleaners can prevent deposits and significantly improve engine reliability.

The electronic differential lock of the Mitsubishi Pajero frequently malfunctions, which becomes particularly problematic when driving off-road. The system does not start or does not function reliably, which can lead to dangerous situations in difficult terrain. These weak points often manifest themselves after just 80,000-100,000 km and are typical of the complex electronics of the all-wheel drive system. The faults can have various causes: defective sensors, dirty contacts, problems with the control unit or mechanical defects in the differential itself. Symptoms include warning lights coming on, unusual noises when the lock is engaged or complete failure of the function. The service life of the components is highly dependent on the operating conditions and maintenance.
Professional maintenance is necessary for the proper functioning of the complex system. The sophisticated Mitsubishi Pajero differential lock components require regular inspection of the sensors and actuators as well as cleaning of the electrical contacts every 30,000 km. Diagnosis is carried out using special test equipment that checks the electronic signals and mechanical functions. Repairs often involve replacing sensors, cleaning the contacts or, in severe cases, overhauling the entire differential. Regular maintenance and avoiding extreme loads can significantly improve reliability.
The turbocharger of the 2.5 TD engine shows typical signs of wear and failure between 100,000 and 150,000 km mileage. These frequent faults are manifested by a drastic loss of power, bluish or black smoke from the exhaust and unusual whistling noises. The weak points are mainly in the bearings and seals of the turbocharger, which are subjected to high temperatures and speeds. Insufficient lubrication or contaminated oil can lead to premature wear. The symptoms often develop gradually: initially a slight loss of power, then increasing oil consumption and finally complete failure. If the damage is advanced, metal chips from the defective turbocharger can damage the engine. The service life is highly dependent on the quality of maintenance and the operating conditions.
A professional inspection is essential for the early detection of turbocharger damage. The heavy-duty Mitsubishi Pajero 2.5 TD turbochargers require regular oil changes with high-quality oils every 10,000 km and air filter checks. The diagnosis includes pressure measurements, visual inspection of the turbine blades and checking for oil leaks. At the first sign of damage, the turbocharger should be overhauled or replaced to prevent consequential damage to the engine. Preventive measures such as proper warm-up and cool-down phases can significantly extend the service life.
The gasoline engines 2.0 GDI and 1.8 GDI of the Mitsubishi Pajero have specific problems with the direct injection. These common faults manifest themselves in rough idling, loss of power and increased fuel consumption. The weak points are mainly due to coking of the intake valves and injectors, as direct injection does not allow the fuel to clean the valves. Problems typically occur after 60,000-100,000 km, depending on driving conditions and fuel quality. Symptoms also include difficulty starting, especially when the engine is cold, and the check engine light coming on. With advanced coking, the engine may no longer function properly and will not start. The reliability of these engines is highly dependent on regular maintenance and high quality fuels.
A systematic check is necessary for the maintenance of the GDI systems. The sensitive Mitsubishi Pajero GDI injection components require special cleaning procedures and regular removal of carbon deposits every 40,000 km. Diagnosis is carried out by endoscope examination of the combustion chambers and pressure measurements in the fuel system. Repairs often include professional cleaning of the intake valves, replacement of the injectors or overhaul of the entire injection system. Preventive measures such as the use of high-quality fuels and regular driving at higher engine speeds can reduce coking and maintain engine performance.
