2014 Buick LaCrosse

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 LaCrosse.

Body PASSENGER CARTransmission Automatic (S6)

The 2014 Buick LaCrosse is a passenger car equipped with a six‑speed automatic transmission and returns an EPA‑estimated 18 city/28 highway/21 combined mpg. Its engine requires 5.0 quarts of 5W‑30 oil, a detail that underscores the modest maintenance footprint of the powertrain. Owner‑reported issues total 63 complaints, with the electrical system leading the tally and five recalls issued for the model year. Across the 2005‑2019 production run, complaint volumes peaked at 314 in 2005 and fell to just six by 2019, placing the 2014 edition well below the early‑generation highs but still above the final‑year low, suggesting a mid‑cycle reliability improvement that continued to trend downward.

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 2014 Buick LaCrosse falls within a clear downward trend of reliability issues, with total complaints dropping to 63 from 128 in 2013. While it shares the same number of recalls (5) as the 2012 and 2013 model years, it marks the beginning of a steady decline in Technical Service Bulletins (TSBs) from a peak of 1,950 in 2013 down to 1,811. The most frequent complaints for 2014 involve the electrical system (9) and steering (8), though the data does not specify the root causes of these failures. Additionally, the 2014 model saw a reduction in federal oversight, recording zero investigations compared to two each in 2012 and 2013, alongside seven crash and one fire complaint. This year represents a pivotal point in the generation's arc, transitioning toward the lowest complaint volumes seen in the later years of the run. Because it offers a significant improvement in stability and fewer reported issues than its immediate predecessors, the 2014 is a good year to buy.
