2015 Chevrolet Suburban

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

Body SUVTransmission Automatic 6-spd

The 2015 Chevrolet Suburban is an SUV on a 4WD platform paired with a 6-speed automatic transmission, returning EPA economy of 16 city, 23 highway, and 18 combined mpg — figures that come with an 8.0-quart, 0W-20 oil requirement underscoring the maintenance footprint of a vehicle this size. With 427 total owner complaints, 11 recalls, and Service Brakes as the top complaint area, the 2015 lands in the middle of the model's complaint history, which spans 1990 through 2024 and ranges from a peak of 1,004 complaints in 1994 to just 36 in 2024. That places this model year in a moderate but notable zone of the Suburban's reliability record — far from the worst era, yet carrying enough brake-related concerns to warrant close attention from anyone researching this generation.

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 provided federal record omits the 2015 model year entirely, skipping from 2009 to 2021, which prevents a comparison to the immediate years before and after. However, the broader historical trend shows complaints and recalls typically spike in early production years—such as 577 complaints and 9 recalls in 2001—before dropping as models mature, evidenced by the decline to 56 complaints and 3 recalls in 2006. For the 2015 Suburban, the isolated data reveals a concerning concentration of issues, with 118 service brake complaints alone rivaling the 161 total complaints of the closest earlier recorded year (2009), alongside 21 crash and 8 fire complaints. Because 2015 sits in a data gap and exhibits these significant brake and crash figures without a specified root cause, it implies a high-risk profile; therefore, buyers should avoid this year and seek a later model with a validated track record.
