2010 Buick Enclave

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2010 Enclave.

Body SUVTransmission Automatic 6-spd

The 2010 Buick Enclave is an SUV paired with a 6-speed automatic transmission, with an engine oil capacity of 5.5 quarts of 5W-30 API and EPA fuel economy rated at 16 city, 22 highway, and 18 combined mpg. Of the 275 owner complaints and 6 recalls logged for this model year, steering emerges as the dominant trouble area — the kind of early-life pattern researchers expect to see in a nameplate's first few model years. Sitting just two model years into the Enclave's 2008–2026 production run, the 2010 represents a sharp drop from the 536 complaints recorded for the 2008 debut and previews the long downward trend that ultimately bottoms out at 2 complaints in 2026, a useful middle stop on the model's reliability arc.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 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.

In 2010 the Enclave recorded 275 federal complaints, 6 recalls, 2 investigations, and 1,404 technical service bulletins (TSBs), positioning it midway between the higher‑complaint, higher‑recall years of 2008‑2009 and the sharply declining trend that began in 2012. Compared with the surrounding model years, 2010’s complaint count is modestly above the post‑2012 low (as low as 12 complaints in 2022) but well below the 2008 peak of 536, while recall activity remains steady at six per year through 2012. The top complaint categories—Steering (101), Engine (49), Power Train (13) and “Unknown/Other” (12)—suggest that most issues are mechanical rather than safety‑critical, and crash‑related complaints are limited to five with only one fire report. Overall, the 2010 Enclave sits in a transitional phase where problem frequency is decreasing but has not yet reached the minimal levels seen in later years. **Takeaway:** The 2010 model is relatively safe to buy, though it carries slightly more reported issues than newer model years; it remains a reasonable choice if priced competitively.
