Best Model Years
2003-2006 (Later Gen 3 models saw some refinements and generally have better parts support, though core issues like timing belt remain)
Years to Avoid
None specifically to avoid, but earlier Gen 3 models (2000-2002) are more likely to have accumulated neglect and severe rust.
Biggest Strengths
- Rugged frame and body-on-frame design (earlier Gen models, Gen 3 is unibody with integrated frame, still very strong)
- Capable off-road performance
- Generally strong V6 engine (if timing belt maintained)
Top Risk Areas
The systems that tend to fail first on the 2000 Mitsubishi Montero, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The 3.5L V6 engine (6G74) commonly develops hardened valve stem seals over time, leading to significant oil consumption and blue smoke on startup or deceleration. This can foul spark plugs and catalytic converters.
The 3.5L V6 is an interference engine, meaning timing belt failure causes catastrophic engine damage. The belt, tensioners, and water pump must be replaced at strict intervals, often neglected by previous owners.
Due to its age and construction, the Montero is prone to frame, underbody, and body panel rust, especially in regions exposed to road salt. This can compromise structural integrity and make repairs difficult.
2000 Mitsubishi Montero Mileage Danger Zones
The mileage windows when the 2000 Mitsubishi Montero most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the vehicle should still be in excellent condition, with primary concerns revolving around basic fluid changes and tire rotation.
Maintenance Zone
This mileage is the critical first timing belt service interval for the 3.5L V6. If not done, it is a ticking time bomb.
Elevated Risk Zone
Another potential timing belt interval if the first was missed or for vehicles with a different service schedule. Suspension wear items begin to show, and valve stem seal issues may emerge.
High Risk Zone
Beyond 120k miles, most major wear components are at or past their service life. Expect increased oil consumption, potential electrical gremlins, and the full range of age-related issues.
2000 Mitsubishi Montero Ownership Cost Outlook
What it typically costs to keep the 2000 Mitsubishi Montero on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$600-900 (assuming timing belt is done)
Moderate Repairs
$800-2,000 periodically (for valve seals, suspension, electrical)
How Long Does the 2000 Mitsubishi Montero Last?
Focus on examples with comprehensive service records, especially for the timing belt. Lower mileage doesn't guarantee freedom from age-related issues like rust or valve stem seals; condition and maintenance history are paramount.

EQUIPMENT:OTHER:LABELS
CERTAIN PASSENGER VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 208, 'OCCUPANT CRASH PROTECTION.' THE BILINGUAL ENGLISH/SPANISH REMOVABLE AIR BAG WARNING LABELS AFFIXED TO THE DASH AND TO THE SUNVISOR DO NOT MEET THE SIZE REQUIREMENTS OF THE STANDARD.
AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE
Mitsubishi Motors North America, Inc. (MMNA) is recalling certain 1998-2000 Montero vehicles. These vehicles were equipped with Non-Azide Driver air bag Inflators (NADI) and do not contain phase stabilized ammonium nitrate (PSAN) propellant.
