Fuel Economy & Engine Specs

The engine also features active fuel management, a cylinder-deactivation system that shuts down four of the eight cylinders when coasting or highway cruising under light loads to save fuel.
The Suburban’s standard 6-speed automatic transmission features tap-up/tap-down gear selection on the column shifter, giving the driver easier manual gear control for grades, and a tow/haul mode offers the driver improved control of transmission shift points when dealing with heavy loads. Environmental Protection Agency (EPA) fuel economy estimates for 2-wheel drives are 16 miles per gallon in the city and 23 mpg on the highway; estimates are 15 mpg city/22 mpg hwy on 4WDs.

These safety recalls have been issued by the National Highway Traffic Safety Administration (NHTSA) regarding the 2015 Chevrolet Suburban:
The overhead airbags may be torn or punctured by roof rack hardware, reducing airbag effectiveness and increasing the injury risk during a crash.
Defective airbag-sensing and diagnostic module software may fail to deploy the front airbags and seatbelt pretensioners in a crash.
The ignition switch may bind in the srart position and later snap back to the accessory position while driving, causing a loss of power, steering and braking assist and deactivating the airbags.
There may be a sudden loss of electric power-steering boost during vehicle operation.
On 4WD models, an electrical short may cause the transfer case to shift to neutral, allowing the vehicle to roll away or creating a sudden loss of power.
A loose automatic transmission cooler fitting may spray transmission fluid on a hot engine component, creating a fire risk.
Recall repairs are required by law, even if the vehicle is out of warranty. Your dealer can check to see if the repairs were performed and, if not, will fix the car at no charge to you.
Safety Ratings & Warranties
The NHTSA gave the 2015 Suburban a 4-star overall rating with four stars for front impacts, five for side impacts and 3 stars for rollover resistance.
The independent Insurance Institute for Highway Safety did not crash-test the 2015 Suburban.
General Motors covered the 2015 Suburban with a 3-year/36,000-mile basic warranty with free roadside assistance, a 6-year/100,000-mile corrosion-perforation warranty and 5-year/100,000-mile powertrain coverage.
A certified pre-owned (CPO) Suburban cannot be more than 5 years old or have greater than 75,000 miles on the odometer. Each CPO Suburban undergoes a 172-point inspection. Those that pass receive a 12-month/12,000-mile bumper-to-bumper warranty plus whatever remains on the transferable original 5-year/100,000-mile powertrain coverage. Also included is a new 2-year/30,000-mile maintenance plan and roadside assistance.
Other Cars to Consider
2015 Ford Expedition EL — The extended-wheelbase version of Ford’s biggest SUV is almost 4 inches shorter than the Suburban but, thanks to a lower cargo floor, beats it by nearly 10 cu ft. on cargo-carrying space. Its 9,200-lb tow rating also beats the Suburban by almost 900 pounds. A new 365-hp 3.5-liter EcoBoost V6 provides smooth turbocharged power. The Expedition’s independent rear suspension rides better than Chevy’s live rear-axle setup.
With a legacy some 80 years long, Chevy’s full-size Suburban offers undeniable safety, security and trailer-towing ability. The LT trim comes with many standard features buyers want, such as an 8-in MyLink infotainment system, Siri Eyes-Free, text-message alerts, leather seats, a power lift gate, forward-collision alert and lane-departure warning. Look for a 4-wheel-drive version if you live in a mountainous area or snow country or if you must deal with unpaved roads. The Suburban enjoys a high resale value and has a solid reputation for durability. A certified pre-owned model is a good way to go. Always get a car history report before you buy, and make sure any applicable recall repairs on the Suburban you are considering have been performed by a GM dealer.
