2023 Buick Enclave

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Enclave.

Transmission Automatic 9-spd

The 2023 Buick Enclave pairs a 9-speed automatic transmission with an engine requiring 6.0 quarts of 5W-30 or 0W-30 oil, yielding EPA fuel economy of 17 city, 25 highway, and 20 combined mpg.

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 97,500 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 2023 Buick Enclave sits in the middle of the second generation (2018 onward), a period defined by a sharp drop in complaints and recalls compared to the first generation (2008–2017). With only 18 complaints and zero recalls, the 2023 model is among the most trouble-free years in the entire federal record, continuing the downward trend from 2022’s 12 complaints and one recall. The top complaint areas—exterior lighting (5), seat belts (2), and electrical system (2)—are minor and not indicative of a systemic issue, and the two crash complaints do not point to a widespread safety concern. The TSB count of 509 is lower than the 620 in 2022 and the 766 in 2019, suggesting fewer dealer-level fixes are needed. Overall, the 2023 Enclave represents a low-risk, reliable choice within the generation, making it a good year to buy for a used vehicle.
