2001 Mitsubishi Montero Sport

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 Montero Sport.

Body SUV

The 2001 Mitsubishi Montero Sport is a mid-size SUV that, with a 4.9-quart oil capacity requiring 10W-30 or 5W-30 viscosity, reflects a conventional powertrain design for its era. Within the model’s 1998–2009 complaint history, this year stands out as the highest with 245 total owner complaints—more than any other—and six recalls, led by issues in the service brakes (hydraulic) system. For a researcher, the 2001 Montero Sport represents the reliability low point of the generation, making it a critical reference for studying systemic brake-related failures and recall patterns in this SUV line.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 60,000 mi; coolant at 60,000 mi. The big-interval services (at 60,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2001 model year represents the clear peak of federal activity for this generation, with 245 complaints, six recalls, and 162 technical service bulletins—levels that more than double the 2000 model’s 98 complaints and 83 TSBs and dramatically exceed the 2002 model’s 61 complaints and 57 TSBs. Across the 1998–2004 arc, the federal record builds steadily from 35 complaints in 1998 to this 2001 apex before falling sharply thereafter, placing 2001 at the generation’s highest point of reported issues. The 2001 data show Service Brakes, Hydraulic as the dominant complaint category, followed by Electrical System and Engine & Engine Cooling, alongside 26 crash-related and 6 fire-related complaints, though the federal record does not specify root causes. Because this year sits at the absolute crest of complaints and recalls while immediately adjacent years show markedly lower activity, it signals the generation’s most concentrated volume of reliability and safety-related complaints. Consequently, the 2001 Montero Sport is not a recommended purchase, as the federal record shows this model year carries the generation’s highest complaint, recall, and TSB volume.
