The Mitsubishi Pajero 4, known for its off-road capabilities and robust design, has gained popularity among SUV enthusiasts. However, like any vehicle, it is not without its fair share of issues. In this article, we will discuss some common problems that owners have encountered with the Mitsubishi Pajero 4, ranging from engine-related concerns to issues with the transmission, suspension, brakes, and more.
- Engine Troubles: The Pajero 4 offers various engine options, including gasoline and turbo diesel variants. Here are some engine-related issues that have been reported:
a. Software Failure and Crankshaft Bearing Issues: In early 2008, a software failure occurred during the engine assembly, resulting in the installation of undersized crankshaft bearings. This led to engine knocking and necessitated the replacement of the short block or the entire engine under warranty.
b. Oil Consumption: With high mileage, the 3.8-liter gasoline engine may start consuming excessive amounts of oil. This can usually be resolved by updating the valve stem seals or, in extreme cases, replacing the piston rings.
c. Intake Manifold Flaps: Some Pajero 4 models with the 3.8-liter engine experienced issues with intake manifold flaps falling into the cylinders due to loose screws. Applying thread sealant to the damper mounting screws can serve as a preventive measure.
- Transmission and Gearbox: The Pajero 4 is equipped with reliable transmissions and gearboxes. However, a few concerns have been raised:
a. Automatic Transmission: The automatic transmission may exhibit shocks when shifting from third to fourth gear, especially in warm conditions. These symptoms typically resolve themselves over time, and no significant malfunctions have been reported.
b. Kardan Backlash: Some owners have noticed a knocking sound when releasing or pressing the gas pedal, indicating backlash in the rear gearbox. While this issue does not affect the transmission’s durability, fixing it may require replacing the rear gearbox and drive shaft.
- Suspension and Steering: The Pajero 4’s suspension and steering components have their own set of issues:
a. Front Anti-roll Bar Bushings: The front anti-roll bar bushings may require replacement after approximately 25,000 to 40,000 kilometers, as they tend to wear out and cause creaking in the front suspension.
b. Suspension Bushings: The bushings and struts of the rear stabilizer and shock absorbers may require replacement after 120,000 to 150,000 kilometers of usage.
c. Corrosion and Body Rigidity: The Pajero 4’s body is susceptible to scratches, chips, and corrosion, especially on older models. Some owners have reported insufficient body rigidity, resulting in door abrasions and dust infiltration. Additional seals or strengthening measures can help address this issue.
- Brakes and Electrical System: Several concerns have been identified regarding the brakes and electrical system:
a. Brake Disc Beating: After 20,000 to 30,000 kilometers, the brake discs may develop a beating issue. While turning the discs might temporarily alleviate the problem, replacing them with higher-quality alternatives is often a more effective solution.
b. ABS Wiring: Chafing of the ABS wiring near the rear left boot of the drive can trigger warning lights, such as ABS, ASC OFF, and slippery road indications. Properly securing the wiring can resolve this issue.
c. Electrical Wiring Fraying: Over time, the stock cable of wires may fray, leading to malfunctions in components like the horn and airbag. Repairing or replacing the damaged wiring is necessary to ensure proper functionality.
Conclusion: The Mitsubishi Pajero 4, with its impressive off-road capabilities and sturdy design, has become a sought-after SUV. However, potential buyers should be aware of the common issues associated with this model. While these problems may arise, timely maintenance, regular inspections, and addressing any concerns promptly can help ensure a smooth and reliable driving experience with the Pajero 4.
