2024 Buick Encore GX

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2024 Encore GX.

Transmission Automatic 9-spd

The 2024 Buick Encore GX is the latest iteration of Buick’s subcompact crossover, built on General Motors’ current VSS‑F platform and paired with an automatic nine‑speed transmission that delivers the model’s EPA‑rated 26 mpg city, 28 mpg highway and 27 mpg combined fuel economy. Its powertrain and chassis are calibrated for urban versatility while the vehicle’s modest 26 total owner complaints—primarily concentrated in the electrical system and accompanied by a single recall—reflect a continued trend of improving dependability since its 2020 debut, which recorded the highest complaint count of 65. Compared with the model‑year range of 2020‑2025, the 2024 Encore GX sits near the low‑end of the complaint spectrum, suggesting that its reliability is solidifying as the line matures.

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 Buick Encore GX generation shows a clear downward trend in complaints and technical service bulletins from its 2020 launch, with the 2024 model year recording 26 complaints—a slight uptick from the 23 in 2023 but still well below the 65 seen in 2020. Recalls have been intermittent, and 2024’s single recall breaks the recall-free streak of 2023, though it remains lower than the two recalls in each of the first two model years. The 2024 complaints are concentrated in the electrical system, with 10 of the 26 reports, while engine and exterior lighting issues account for a few more; no crashes or fires are reported. Technical service bulletins continue to decline, reaching 410, which suggests fewer documented fixes are needed as the generation matures. This year falls late in the improvement arc, offering generally low reported problems, but the electrical focus and the presence of a recall mean a buyer should verify that any related campaigns have been addressed. Overall, the 2024 Encore GX is a solid used choice, provided a pre-purchase inspection pays close attention to the electrical system.
