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 every 60,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 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 2025 Encore GX sits at the favorable end of a clear improvement arc: federal complaints have fallen from 65 in 2020 to just 13 in 2025, recalls have dropped from two per year in 2020–2021 to zero in both 2023 and 2025, and technical service bulletins have declined from a peak of 667 in 2021 to 204 this year. The 2025 model year records the lowest complaint, recall, and TSB counts of the generation, with only four complaint categories logged — each at a single report — and no crash complaints, though one fire complaint appears in the data. The data does not specify root causes for any of these isolated reports. With zero recalls and zero investigations, the 2025 model presents the cleanest federal record to date, though as the current model year it has the least accumulated real-world exposure. Based on the available federal data, the 2025 Encore GX is a strong candidate for purchase, provided the buyer accepts the inherent uncertainty of a model year still early in its service life.
