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 6,000 mi. The big-interval services (every 6,000 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 Subaru Impreza presents a notably clean federal record, with only 4 complaints filed that year—the lowest complaint count in the dataset's recent history, down from 14 in 2021 and 12 in 2022. The model saw 2 recalls (matching 2024's rate but higher than 2022's single recall), zero investigations, and 200 TSBs—a figure that continues a steady decline from 304 in 2021 and 242 in 2022. The target year's top complaint areas were tires (2 cases) and a single combined complaint involving electrical, engine, and fuel systems, with zero crash-related complaints and zero fire complaints. Compared to the generation's peak complaint years—2019 (191 complaints) and 2012–2013 (242–248)—2023 represents a dramatic improvement, though 2024 saw a rebound to 29 complaints. The declining TSB trajectory suggests maturing of the platform's service literature. Takeaway: 2023 appears to be a strong candidate within this generation, offering the lowest complaint rate on record alongside moderate recall activity and no safety-related complaints, though the 2024 rebound warrants monitoring whether any emerging issues from that year might eventually affect 2023 models.
