2015 Subaru Forester

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

Body SUV

The 2015 Subaru Forester, an SUV requiring 5.1 to 5.4 quarts of 5W-30 or 0W-20 API oil, recorded 613 owner complaints — primarily targeting air bags and prompting three recalls — a figure that places this model year well beneath the 2019 peak of 831 complaints across the 1998–2026 history but notably above the 12-complaint floor of 2026. That tally situates the 2015 model as a mid-tier reliability chapter in the Forester's decades-long record, reflecting neither the generation's best nor its most troubled showing.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 6,000 mi; spark plugs every 60,000 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 2015 Subaru Forester represents a significant spike in reported issues within its generation, recording 613 complaints—a substantial increase over the 403 seen in 2014. This volume is notably higher than the 405 complaints reported for the 2016 model, placing 2015 as a localized peak in the trend. Across this era, there is a general upward trajectory in complaints and technical service bulletins, with 2015 maintaining an elevated 492 TSBs compared to 374 in 2013. The most frequent complaint areas for 2015 include Air Bags (64), Engine (62), and Suspension (62), though the data does not specify the root causes for these issues. Despite the high complaint volume, the year saw only 3 recalls and 0 investigations. Given that 2015 marks one of the highest complaint volumes in its immediate window, it is not a recommended year to buy.
