Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the 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 2022 Buick Encore GX recorded 29 consumer complaints and 1 safety recall, placing it below the 20202021 peaks of 65 and 50 complaints but above the 2023‑2025 lows of 23, 26 and 13 complaints. Recalls have generally declined, with only two recalls in 2020 and 2021, one in 2022 and 2024, and none in 2023 and 2025, indicating a relatively stable recall pattern across the generation. The most frequently cited complaint categories for 2022 are Power Train (7 reports) and Unknown Or Other (5 reports), together accounting for the majority of grievances. No crash‑related or fire‑related complaints were logged for the target year, and investigations remain absent throughout the period. Consequently, the 2022 model sits in the middle of a downward complaint trajectory and carries a modest recall count, making it a reasonable choice for a used purchase provided the specific vehicle’s recall status is confirmed.
