The Bad
Key weaknesses for the 1991 Montero include susceptibility to rust, particularly in the frame, rear wheel wells, and tailgate. Fuel economy is poor, and on-road handling is decidedly truck-like. Parts availability can be a challenge for specific components, and common engine issues like valve guide seals on the V6 require attention during pre-purchase inspections.
1991 Mitsubishi Montero: Quick Overview
- Engine Options: The primary engine for the 1991 US-market Montero was a 3.0-liter SOHC V6. Earlier models sometimes featured a 2.6-liter inline-four, but the V6 was dominant by '91.
- Horsepower: The 3.0L V6 produced approximately 143 horsepower and 168 lb-ft of torque, providing adequate power for both on-road and off-road driving.
- Fuel Economy: Fuel economy figures were not a strong suit. Owners typically reported around 13-16 miles per gallon (MPG) combined, varying significantly with driving conditions and vehicle maintenance.
- 0-60 Times: Acceleration was leisurely, with 0-60 mph times generally falling in the 11-13 second range, typical for SUVs of its vintage.
- Towing Capacity: The 1991 Montero, when properly equipped, had a towing capacity of around 3,500 pounds, making it suitable for light trailers or small boats.
- Trim-Level Features:
- Base (often referred to simply as Montero): Generally came with essential features such as manual windows, manual door locks, vinyl or basic cloth upholstery, and a robust four-wheel-drive system. It prioritized function over luxury.
- LS (Luxury Sport): Offered more comfort and convenience. Features often included power windows and door locks, air conditioning, cruise control, upgraded cloth interior, a better audio system (AM/FM cassette), and possibly more aesthetic exterior trim. Some LS models featured adjustable shock absorbers (often called "Active ECS" or "Multi-Mode Suspension") providing driver-selectable ride firmness.
- RS (Rally Sport): This trim often provided a slightly more aggressive or sporty appearance, sometimes with unique wheels or graphics, but might have fewer luxury features than the LS, focusing on a rugged, capable image.
- General Features Across Trims: All models boasted a strong body-on-frame construction, capable 4WD with a two-speed transfer case, and ample ground clearance. Many featured front torsion bar and rear leaf spring suspension (or coil springs on later first-gen models), providing durability for off-road use. A rear limited-slip differential was an option on higher trims.

What Problems Does the 1991 Mitsubishi Montero Have?
The 1991 Mitsubishi Montero, while generally robust, has several frequently reported problems and long-term reliability concerns due to its age and design.
Rust: This is arguably the biggest enemy. Common rust areas include the frame, rocker panels, rear wheel arches, and the lower sections of the tailgate. Vehicles in areas with salted roads are particularly susceptible. Thorough inspection of the undercarriage and body is crucial.
Engine Issues (3.0L V6): The 3.0L SOHC V6 engine, while generally durable, is known for premature wear of valve guide seals. This often manifests as noticeable blue smoke from the exhaust, especially on startup or during deceleration, indicating oil burning. Head gasket leaks are less common but can occur, particularly if the engine has been overheated.
Transmission: Manual transmissions are usually very durable. The automatic transmissions, however, can develop issues with age, such as delayed shifts, slipping, or harsh engagement, often due to neglected fluid changes or wear of internal components.
Electrical Gremlins: Minor electrical issues are common, including intermittent dashboard lights, faulty power window motors, and non-functional accessories. Wiring harnesses can become brittle over time.
Suspension and Steering: As with any older vehicle, wear in suspension components like ball joints, tie rod ends, control arm bushings, and shock absorbers is common. The steering box can also develop play, leading to a loose steering feel.
Brakes: Age can lead to common brake issues such as sticky calipers, worn rotors, and issues with the master cylinder or brake lines. Some models had rear-wheel ABS, which can be prone to sensor failures or modulator issues.
Fuel System: Problems with fuel pumps, fuel lines (especially rust on metal lines), and fuel injectors can arise with age.
Recalls: For a 1991 model, major recalls are less common to be active, but historical recalls did exist for various Mitsubishi models around that time, often related to components like fuel system parts, seat belt buckles, or minor electrical concerns. Prospective buyers should check NHTSA records using the VIN, though finding specific recalls active for a 30+ year old vehicle can be challenging. Overall, while the Montero's mechanicals are strong, age-related wear and rust are the primary long-term reliability concerns.

How long will the 1991 Mitsubishi Montero last?
The 1991 Mitsubishi Montero, with diligent maintenance, is known to achieve impressive longevity. Many owners report these vehicles easily reaching 200,000 to 300,000 miles, with well-preserved examples exceeding even that. It's not uncommon to see these trucks still serving faithfully after 25-30+ years of service. Its long-term durability stems from its robust body-on-frame construction and durable drivetrain components. However, this durability is contingent on consistent maintenance, particularly fluid changes and addressing wear items proactively. The primary long-term weakness, as highlighted, is rust, which can compromise the frame and body beyond economic repair if not prevented or addressed early. Engine valve guide seals can also be a long-term issue if neglected, leading to increased oil consumption.
What Technology & Safety Features are Included?
The 1991 Mitsubishi Montero, being a vehicle from the early 90s, reflects the technology standards of its era, meaning its built-in tech and driver-assistance features are minimal by modern standards.
Built-in Tech: The cabin featured a functional, no-frills dashboard with analog gauges for speed, RPM, fuel level, and engine temperature. Basic climate control was standard, typically with manual sliders for temperature and fan speed. Higher trims might have included a digital clock. Some advanced features for its time, like an inclinometer and altimeter, were available in a "Convenience Package" or standard on higher trims, appealing to its off-road audience.
Entertainment: Standard entertainment was an AM/FM stereo with a cassette player. Higher trim levels, like the LS, might have offered a more advanced unit with a graphic equalizer or a premium sound system for the era, possibly with four speakers. CD players were rare or an expensive dealer option, often an aftermarket addition.
Driver-Assistance Features: In the modern sense, driver-assistance features were non-existent. The Montero offered fundamental aids such as power steering for easier maneuverability and power-assisted brakes. Cruise control was an optional convenience feature on higher trim levels.
Safety Features: Safety for the 1991 Montero relied on its strong body-on-frame construction and passive safety measures. Standard safety equipment included three-point seat belts for front occupants and lap belts for rear passengers. Airbags were not standard equipment for this model year and were not an option.
