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 at 105,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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 federal record for the Mitsubishi Montero shows a volatile history of complaints and recalls, characterized by significant spikes in 1995, 1997, and most notably in 2002 with 174 complaints and 110 TSBs. The 2006 model year falls at the end of this arc, reflecting a dramatic decrease in reported issues compared to earlier iterations. With only 4 complaints, 0 recalls, and 0 investigations, the 2006 model is significantly more stable than the 2002 model and only slightly more active than the 2005 model. The few 2006 complaints are distributed across the fuel/propulsion system, service brakes, electrical system, and power train/ESC, though the data does not specify the root causes. Given the minimal volume of recalls and complaints relative to the generation's historical trend, this is a good year to buy.
