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 2017 Buick LaCrosse recorded 34 complaints and 2 recalls, both markedly lower than the peak complaint years of 2005‑2008 (314‑250 complaints) and the recall‑heavy period of 20112014 (4‑5 recalls per year). Complaints showed a general downward trend from 2005 to 2019, with a temporary rise in 2010‑2012 before falling again, placing 2017 near the low‑end of that trajectory. Recalls fluctuated between 2 and 5 annually but settled at the lower end of that range from 2015 onward, with 2017 matching the 2016 figure and below most earlier years. Investigations were zero for 2017, continuing the pattern of no investigations seen after 2014. Taken together, the 2017 model year exhibits comparatively few federal‑recorded issues, suggesting it is a reliable choice among used LaCrosse options.
