2015 Chevrolet Tahoe

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

Body SUVTransmission Automatic 6-spd

The 2015 Chevrolet Tahoe is a full‑size SUV built on a 2‑wheel‑drive platform that pairs a six‑speed automatic transmission with an EPA‑rated fuel economy of 16/23/18 mpg, while requiring 8.0 qt of 0W‑20 engine oil. Its robust drivetrain and sizable interior make it a dependable choice for families and commercial use alike, yet the 2015 model still ranks within the higher end of the Tahoe’s reliability record, with 661 owner complaints—chiefly centered on service brakes—and a total of 16 recalls that year. Positioned just after the 2007 peak of 1,176 complaints, the 2015 Tahoe demonstrates a relatively stable, though not flawless, service history, underscoring the importance of regular brake maintenance for long‑term ownership.

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 model year represents a dramatic inflection point, with federal complaints surging to 661 from just 93 in 2014, while recalls jumped to 16 compared to 4 the prior year and 10 in 2016. This spike coincides with a substantial increase in technical service bulletins to 2,582—the highest in the dataset—with the highest complaint volumes concentrated in service brakes (142), unknown/other (59), electrical systems (48), and fuel/propulsion systems (46), alongside 30 crash-related complaints and 2 fire incidents. While 2016 saw volumes moderate to 253 complaints, the 2015 data reflects peak federal activity for this generation's early years. Given the substantially higher complaint and recall burden compared to both the 2014 predecessor and 2016 successor, buyers should verify all 16 recalls have been completed and budget for potential brake and electrical system attention.
