2003 Mitsubishi Montero problems
The Mitsubishi Pajero (三菱・パジェロ, Japanese: ; English: /pəˈhɛroʊ/; Spanish: ) is a full-size SUV (sport utility vehicle) manufactured and marketed globally by Mitsubishi over four generations — introduced in 1981 and discontinued in 2021.
The Pajero nameplate derives from Leopardus pajeros, the Pampas cat. Mitsubishi marketed the SUV as the Montero in North America, Spain, and Latin America (except for Brazil and Jamaica) due to the term "pajero" being derogatory (meaning "wanker") in Spanish. In the United Kingdom, it was known as the Shogun (将軍), named after the Japanese word for "General." The model was discontinued in North America in 2006.
The Pajero, Montero, and Shogun names were used on other, mechanically unrelated models, such as the Pajero Mini kei car, the Pajero Junior and Pajero iO/Pinin mini SUVs, and the Triton-based Pajero/Montero/Shogun Sport mid-size SUVs. The Pajero is one of four models by Mitsubishi (the others being the Triton, Pajero Sport and the Pajero iO) that share Mitsubishi's heavy-duty, off-road-oriented Super-Select four-wheel-drive system as opposed to their light-duty Mitsubishi S-AWC all-wheel-drive system.
The Pajero has generated more than 3.3 million sales in its 40-year run. The name lives with the smaller Pajero Sport, which is based on the Mitsubishi Triton/L200/Strada pickup. Despite the similarity in name, the Pajero Sport shares none of the original Pajero's underpinnings and is smaller in overall size.

Common 2003 Mitsubishi Montero problems
The Mitsubishi Montero from the 2003 model year has been reported to have several common problems by its owners. These issues range from minor inconveniences to major mechanical failures.
One of the most common problems with the 2003 Mitsubishi Montero is a leaking valve cover gasket. Both valve covers tend to have issues, but the one on the driver's side is more problematic. Almost every Montero that has been seen has an oil leak from this area, which can drip down onto the exhaust and produce a smell. This issue is likely due to the design of the valve cover and gasket, as well as the heat generated by the engine
Another common problem with the 2003 Mitsubishi Montero is a cracked exhaust manifold. This issue is not unique to the Montero, as it is a problem with many cars. However, it seems to be a particular issue with the Gen 3 Montero, as every set of manifolds pulled off has had a crack. This is likely due to the casting or the location of the manifolds, which can cause them to overheat and crack. This issue can lead to a loss of power and a decrease in fuel efficiency
The gauges on the 2003 Mitsubishi Montero are also known to have issues. The fuel gauge may read incorrectly due to a bad resistor, which can cause the gauge to read high or low. The temperature gauge may also have issues, as it may not accurately reflect the engine's temperature. This can lead to overheating or other engine problems if not addressed
The front four-wheel drive lights on the 2003 Mitsubishi Montero are also known to have issues. When shifting between two-wheel drive and four-wheel drive modes, the lights may flash due to a sensor or wiring issue. This can be a minor inconvenience or a major safety issue, depending on the severity of the problem
In addition to these common problems, the 2003 Mitsubishi Montero is also known to have issues with independent front and rear suspension alignment. This can make it difficult to align the car and get a lot of lift out of it. This issue can also make it difficult to drive the car comfortably, especially on rough roads or when towing
The support from Mitsubishi for the 2003 Montero is also known to be lacking. Dealers may not be able to service the car if something goes wrong, and finding a mechanic who knows how to work on the car can be difficult. This can make it challenging to own and maintain the car, especially for those who are not mechanically inclined
In summary, the 2003 Mitsubishi Montero is known to have several common problems, including leaking valve cover gaskets, cracked exhaust manifolds, gauge issues, four-wheel drive light issues, suspension alignment problems, and a lack of support from Mitsubishi. These issues can range from minor inconveniences to major mechanical failures, and can make owning and maintaining the car challenging.
Are old Mitsubishi Monteros reliable?
According to MotorTrend and various forums, the Montero is overall a reliable SUV. However, there are certain model years that run into problems in their transmissions, braking, and engines, which are always certainly expensive to fix. These are the 2001 to 2002 Montero models.
How many miles can a Mitsubishi Montero last?
I have a few customers well into the 300k mile range, and a lot of customers in the 200s. Really it all depends on how well the vehicle is maintained, but it is unusual to see any major failures even at this mileage provided the basic maintenance is done on time.
Why was Montero discontinued?
Unfortunately for Mitsubishi, Montero popularity waned in its later years as buyers started to focus more on crossovers than capable, truck-based SUVs like the Montero — so Mitsubishi cancelled the Montero in the U.S. market following the 2006 model year, and devoted itself instead to selling crossovers.
What kind of engine is in the Mitsubishi Montero?
4 cylinder Diesel engine
The Montero Sport, a new SUV from Mitsubishi comes in 4 variants. The top variant of Montero Sport is powered by the GT 4WD AT a 2442 cc, 4 cylinder Diesel engine that fires 179 hp of power and 430 Nm torque. The 7 seater.

Great handling, great look, and great interior comfort!

My Montero is unable to climb my driveway in snowy, icy, or slushy conditions, despite being purchased for that purpose. I upgraded to Mastercraft Courser C/Ts this year, but the issue persists even after the first snow storm. It's frustrating that my 2002 Dodge Ram with worn summer tires can climb the driveway with ease. I would appreciate any assistance in resolving this issue.

We looked at all the SUVs on the market, but were tired of seeing the same ones on the road. That's when we decided to check out the Mitsubishi Montero. At first, we were hesitant about its full size, but we fell in love with it after taking it for a spin. The Montero has tons of headroom and legroom in both the front and back, which is perfect for my husband who is long waisted. The back door opens and closes like a car door, so we'll never have to hassle with a hatch opening again. Our friends and family are sold on it too! The back seats fold down for lots of storage, and the 3rd row seat is handy for kids. Although its gas mileage is decent, it's not as cavernous as the Chevrolet Trailblazer. However, it has great visibility and is better looking than the 'dog' Durango, but not as expensive as the Toyota Land Cruiser. One thing to note is that we have spent thousands of dollars on regular maintenance, but we'll definitely consider that next time.

I really enjoyed the build quality and interior when I first purchased the vehicle. However, I experienced some regret during the first year due to the 'road wildness' issue. After reading some comments online, I discovered that I needed to change the 'OEM' tires. I switched to Michelin LTS and it made a huge difference. Now, I absolutely love everything about this vehicle. With 97,000 miles on it, I have not had any major problems. It is agile, rock solid, and extremely comfortable both inside and out, with the best visibility. Even though my company would buy me anything I want, I have chosen to stick with this vehicle because there is nothing else out there that interests me.

This is my first full size Montero, two others before were sports. I have noticed that this vehicle is made with better quality materials and is all around a nicer vehicle. However, it was not the right fit for me. Although I had some negative experiences with Mitsubishi, I still believe that it is a nice car. I hope to find a better fit for my needs in the future.
