2023 Mitsubishi Mirage G4

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Mirage G4.

Transmission Automatic (variable gear ratios)

The 2023 Mitsubishi Mirage G4 is a subcompact sedan that pairs an automatic transmission with continuously variable gear ratios, delivering an EPA‑rated 35 mpg city, 41 mpg highway and a combined 37 mpg. Its modest powertrain is complemented by a clean reliability record for the model year, registering only five owner complaints—most of which cluster around structure, seats, or unspecified issues—and no recalls. Across the 2017‑2024 span, complaint volumes have fallen dramatically from a peak of 28 in 2017 to a low of two in 2021, positioning the 2023 iteration as one of the most trouble‑free points in the Mirage G4’s history.

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.

The 2023 Mirage G4 sits near the end of a clear downward trend in federal complaints and technical service bulletins across this generation, with only 5 complaints and 15 TSBs—far below the 28 complaints and 105 TSBs of the 2017 model. Recalls, which were present in 2017 (3) and 2018 (1), have been absent since 2019, and the 2023 model continues that clean recall record. The four complaint areas for 2023 are each isolated single reports covering structure/seats, electrical/brakes, exterior lighting/speed control, and engine, with no crashes or fires recorded, suggesting no widespread pattern. While complaints ticked up slightly from the 2–3 range of 20212022, the overall volume remains very low and consistent with the generation’s mature, trouble-free phase. This data indicates the 2023 Mirage G4 is a reliable choice with minimal reported issues, making it a sound used-vehicle purchase.
