2014 GMC Sierra 1500: Used Car Review

Editor’s note: You may also want to read Autotrader’s GMC Sierra 1500 review for the 2015, 2016, 2017 and 2018 model years.


The 2014 GMC Sierra 1500 light-duty pickup is available as a 2- to 3-passenger regular cab, a 5- to 6-passenger double cab or a 5- to 6-passenger crew cab. Regular-cab models have just two doors and come with a standard 6.5-foot bed or a longer 8-foot bed. The newly named double cab model is slightly shorter and less roomy than the crew cab; it replaces the previous extended cab and features four forward-hinged doors and a 6.5-foot bed only. The crew cab comes standard with the short 5.7-foot bed, but the 6.5-foot bed is optional. Both rear-wheel drive (RWD) and all-wheel drive (AWD) are offered, and 4-wheel anti-lock disc brakes, stability control, front-seat side airbags and overhead airbags come standard.

For 2014, GMC gave the Sierra all-new sheet metal, a roomier interior, updated infotainment, three all-new engines with substantially improved power and fuel economy, a standard 6-speed automatic, new frame mounts, and revised steering, suspension and brakes. For 2014, maximum towing capacity is increased to 12,000 pounds. The latest safety systems are available, including lane-departure warning, forward-collision alert, front and rear park assist, and trailer-sway control. See the 2014 GMC Sierra models for sale near you

Fuel Economy & Engine Specs

The 2014 Sierra 1500 regular, double and crew cabs are available with an all-new 4.3-liter V6 with variable valve timing and direct injection. This engine makes 285 horsepower and 305 lb-ft of torque. Active Fuel Management idles unneeded cylinders to save fuel under light cruising conditions. RWD versions are rated by the Environmental Protection Agency (EPA) at 18 miles per gallon in the city and 24 mpg on the highway, while AWD models get 17 mpg city/22 mpg hwy. Regular unleaded or E85 fuel is recommended, and a 6-speed automatic transmission comes standard.

Also new for the 2014 model year, a 5.3-liter V8 is available on regular, double and crew cabs, burning regular unleaded or E85. Using variable valve timing and direct injection, it produces 355 hp and 383 lb-ft of torque. Equipped with a 6-speed automatic, EPA ratings for RWD models are 16 mpg city/23 mpg hwy, while AWD versions get 16 mpg city/22 mpg hwy. The 5.3-liter V8 also uses Active Fuel Management to save fuel when cruising.

SLT and Denali double and crew cabs are available with a 6.2-liter V8 that produces 420 hp and 460 lb-ft of torque. Premium unleaded is recommended but not required. EPA estimates are 15 mpg city/21 mpg hwy for RWD versions and 14 mpg city/20 mpg hwy with AWD. A 6-speed automatic comes standard.

Standard Features & Options

The 2014 Sierra 1500 comes in base, SLE, SLT and Denali trims.

The base Sierra comes with a cloth 40/20/40-split front bench seat, air conditioning, 17-inch steel wheels, a 4-speaker AM/FM radio with a 4.2-in display, cruise control, dual glove boxes, power door locks, a tilt steering wheel, auto headlamps, chrome bumpers, a locking tailgate, bed corner steps, movable bed tie-downs and manual-folding outside mirrors.

The SLE adds OnStar, power windows and heated mirrors, remote keyless entry, 17-in alloy wheels, a leather-wrapped steering wheel with audio controls, a backup camera, the EZ Lift-and-Lower tailgate that also features remote locking capability, an auto-locking rear differential, deep-tint glass, Bluetooth and a 6-speaker AM/FM/CD stereo with an 8-in IntelliLink touchscreen, SiriusXM radio and HD Radio.

The SLT brings the 5.3-liter V8, dual-zone auto climate control, a tilt-telescopic steering wheel, adjustable pedals, a trailer hitch, leather seats, heated power front seats, a memory driver’s seat, 18-in alloys, an auto-dimming rearview mirror, power-folding turn-signal mirrors, fog lamps, a rear defroster and a garage-door opener.

The Denali adds navigation, a heated steering wheel, front and rear parking assist, ventilated front seats, a touring suspension, 20-in chrome alloys, a chrome grille, body-color bumpers and a 7-speaker Bose stereo.

The National Highway Traffic Safety Administration (NHTSA) has announced these recalls for the 2014 GMC Sierra 1500:

A sticking ignition switch may spring back to the accessory position, cutting power to the engine, airbags, power steering and power brakes.

Faulty seat-bracket welds may allow the seats to come loose in a crash.

On AWD Sierras, a short may cause the transfer case to shift into neutral unexpectedly.

The V6 exhaust manifold may melt plastic parts, creating a fire risk.

The seat-belt tension cable may fatigue, insufficiently restraining the driver.

With vinyl flooring, floor mats may lodge under the accelerator pedal.

The base AM/FM radio amplifier may fail, shutting off the seat-belt or door-open warning chime.

A loose transmission cooler line may spray fluid onto hot engine parts, creating a fire risk.

Tie rods can come loose from the steering gear, causing a loss of steering control.

The front passenger airbag may not fully inflate in a crash, creating an injury 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, they’ll fix the car at no charge to you.

Safety Ratings & Warranties

NHTSA gave the 2014 Sierra five stars overall, with five for frontal and side impacts and four for rollover performance.

The independent Insurance Institute for Highway Safety rated the 2014 Sierra crew cab and double cab as Good for moderate-overlap front and side impacts, head-restraint, seat-crash performance and roof strength, but the nonprofit did not rate regular-cab models.

GMC covered the 2014 Sierra with a 3-year/36,000-mile bumper-to-bumper warranty, a 5-year/100,000-mile powertrain warranty with roadside assistance and a 6-year/100,000-mile corrosion-perforation warranty.

GMC certified pre-owned (CPO) vehicles can’t have more than 75,000 miles on the odometer and must be 5 years old or less. Every CPO GMC Sierra 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.

Other Cars to Consider

2014 Ford F-150Ford adds the Tremor sport truck edition to the F-150 lineup for 2014. The engine lineup continues with a 365-hp twin-turbo EcoBoost 3.5-liter V6, a 302-hp 3.7-liter V6, a 360-hp 5.0-liter V8 and a 411-hp 6.2-liter V8. Max towing capacity remains at 11,300 pounds.

2014 RAM 1500 — A new 240-hp 3.0-liter V6 turbodiesel with a 28 mpg hwy EPA rating joins the 305-hp 3.6-liter V6 and 395-hp 5.7-liter HEMI V8. Other features include an 8-speed automatic transmission with a twist-knob shifter, plus an optional air suspension and RamBox enclosed bed storage.

Autotrader’s Advice

Double and crew cabs with the midlevel 5.3-liter V8 are what most people want. We’d recommend at least the SLE trim to get alloy wheels, a backup camera and the 8-in touchscreen. Avoid modified trucks, look for lower-mileage examples, and check out CPO versions. Be sure to get a vehicle-history report, and make sure that the many 2014 Sierra safety recalls have been performed.
