2009 Buick LaCrosse

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 LaCrosse.

Body PASSENGER CAR

The 2009 Buick LaCrosse is a passenger car powered by a powertrain requiring 5 quarts of 5W-30 API-certified engine oil, and it represents a model year situated within a complaint history spanning 2005 to 2019 where owner-reported issues peaked at 314 in 2005 and subsequently declined to a low of 6 by 2019; with 106 total complaints on record and exterior lighting cited as the primary concern alongside two recalls, the 2009 model falls in the middle of this trajectory, suggesting it inherits some of the earlier reliability challenges while benefiting from incremental improvements over the model's trouble-prone debut.

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.

The 2009 Buick LaCrosse sits at a clear inflection point in the model's federal record: with 106 complaints, it marks the lowest complaint volume of the entire 2005–2019 span and follows four consecutive years of 249–314 complaints. Its two recalls and zero investigations also represent an improvement from 2005–2007, which posted four or five recalls annually and one investigation in both 2006 and 2007, even though TSBs continued climbing to 1,038 in 2009. After 2009, complaint counts rebounded to 169–204 through 2012, and recalls ticked upward again, suggesting the 2009 model year captured a temporary dip in reported owner problems rather than a sustained low. Within that year, the leading complaint categories were exterior lighting (38), air bags (18), electrical system (10), and a combined electrical/exterior lighting category (7), with 3 crash-related and 4 fire-related complaints on file. Because the federal record does not specify root causes, we cannot attribute these to any particular defect, but the overall complaint, recall, and investigation counts make 2009 one of the cleaner model years in this generation. For a used-car buyer, that makes 2009 a comparatively attractive year to buy within this LaCrosse range, provided a pre-purchase inspection confirms the specific vehicle's condition.
