2019 Buick Cascada

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 Cascada.

Body PASSENGER CARTransmission Automatic (S6)

The 2019 Buick Cascada is a passenger car equipped with a 5.8-quart engine paired with a 6-speed automatic transmission, delivering EPA-estimated fuel economy of 21/29/24 mpg across city/highway/combined driving. Over its four-year production run spanning 2016 through 2019, this model year marked the most refined iteration of the Cascada, accumulating just 5 owner complaints compared to 21 during the 2016 launch year, with zero recalls—a trajectory that reflects substantial improvements in build quality and positions the 2019 as the strongest conclusion to the Cascada's brief tenure in Buick's lineup.

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 60,000 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 2019 Cascada sits at the favorable end of a consistent improvement arc: complaints fell from 21 in 2016 to just 5 in 2019, TSBs dropped from 983 to 536, and the single recall and investigation recorded in 2016 did not recur in any subsequent model year. The 2019 data shows no recalls, investigations, crash complaints, or fire complaints, with the top complaint categories limited to three Structure reports and one each for Visibility/Wiper and Power Train/Engine — the data does not specify root causes for these few items. Compared to the elevated 2016 launch year and the steady declines through 2017 and 2018, the 2019 model represents the cleanest federal record of the generation. This downward trajectory across all tracked metrics suggests the platform matured well. For a used buyer, the 2019 is the strongest year to buy in this generation based on the federal complaint and recall trend.
