2015 Mitsubishi Outlander — 2.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 Outlander 2.4L.

Body SUVEngine 2.4LTransmission Automatic (AV-S6)

The 2015 Mitsubishi Outlander is an SUV powered by a 2.4L engine paired with an automatic (AV-S6) transmission, delivering an EPA-estimated 25/30/27 mpg and requiring a 4.2-4.5 engine oil capacity of 0W-20 viscosity. However, that same powertrain is the epicenter of the vehicle's flaws, as the 233 total owner complaints predominantly target the Power Train alongside 12 separate recalls. Standing as the highest-complaint year across the model's entire 2003-2025 history, the 2015 Outlander represents the low point of the nameplate's reliability record, meaning researchers should approach this specific iteration as an exceptionally problematic outlier rather than a typical example of the model.

Service quick specs OEM factory data

Capacities, torques and tune-up values from the factory service manual.

This engine holds 4.2-4.5 of 0W-20 engine oil, GL-5 in the differential, DOT 3 brake fluid. Torque the oil drain plug to 26.0-32.0 ft-lbs. The firing order is 1-2-3-4-5-6. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

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; 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 2015 Mitsubishi Outlander stands out as the worst year in the entire federal record, with 233 complaints—far exceeding the 45 complaints in 2014 and the 167 in 2016. This spike is accompanied by 12 recalls and 202 TSBs, both the highest figures in the dataset, indicating a clear peak in reported issues for this generation. The trend shows a sharp rise from the relatively stable 2012–2014 period, followed by a decline after 2016, suggesting the 2015 model year was an outlier in terms of owner dissatisfaction. The top complaint area is the powertrain (90 complaints), and there are 6 crash-related and 2 fire-related complaints, though the data does not specify root causes. Given this spike in complaints and recalls relative to both earlier and later years, the 2015 Outlander is a poor choice for a used purchase; buyers should instead consider the 2014 or 2017 model years, which show significantly lower complaint and recall counts.
