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 at 120,000 mi. The big-interval services (at 120,000 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.

Across the generation, the Mitsubishi Mirage G4 has seen a significant decline in federal issues, with complaints dropping from 28 in 2017 to a low of 2 in 2021. This downward trend is mirrored in recalls, which vanished after 2018, and technical service bulletins (TSBs), which fell from 105 in 2017 to 27 in 2021. The 2021 model represents the nadir of reported complaints before a slight increase began in 2022. For 2021, the only reported issues involved forward collision avoidance and the electrical system, though the data does not specify the root causes. With zero recalls, zero crash or fire complaints, and the lowest complaint volume of the entire record, the 2021 model is an excellent year to buy.
