2015 Buick Verano

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 Verano.

Body PASSENGER CAR

The 2015 Buick Verano is a passenger car that requires 6.0 quarts of 5W-30 engine oil for maintenance, fitting into the compact sedan segment of Buick's model range. With 58 total owner complaints recorded and zero recalls for this model year, the vehicle demonstrates a notably stable production record, particularly when compared to its earlier model years. This places the 2015 model in the middle of the vehicle's 20122017 complaint trajectory, which showed a steady decline from a high of 106 complaints in 2012 down to just 9 by 2017, indicating improving refinement and addressing of previous concerns—though notably, the electrical system remained the top complaint area across the model's history.

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 2015 Verano marks a distinct improvement in the generation's federal record, with complaints falling to 58 from a consistent 101–106 range in the three prior model years and recalls dropping to zero after 2014's six-campaign peak. Technical service bulletins also declined to 1,342, continuing a steady descent from the 2013 high of 1,545, while investigations remained absent across the entire 2013–2017 span. The 2015 complaint profile centers on the electrical system (11 reports), air bags (8), and an unspecified "Unknown Or Other" category (8), with two crash complaints and one fire complaint recorded; the data does not specify root causes for these issues. By 2016, complaints held near 2015 levels but recalls returned with two campaigns, and 2017 saw a further drop to just nine complaints as production ended. The 2015 model year sits at the generation's low point for both complaint volume and recall activity, suggesting a relatively well-resolved production phase. For a used buyer, 2015 represents the strongest candidate in this generation provided all electrical-system and air-bag recalls from adjacent years have been addressed on the specific vehicle.
