The go-anywhere 3500HD is unchanged for 2022, which means buyers still have a huge array of trim/body/drivetrain variants to pick from. You can even choose four or six-wheel configurations, for greater towing capacity and off-road prowess.
2022 GMC Sierra 3500HD
Unlike other websites and magazines, our ratings are not based solely on a singular road test, but rather a more encompassing batch of criteria: quality, safety, comfort, performance, fuel economy, reliability history and value. When comparing vehicles using our Rating System, it's important to note that the rating earned by each vehicle correlates only to the models within its class. For example, a compact car cannot be compared to a SUV—They are different vehicles altogether.
You can interpret our ratings in the following way:
5-Star: Outstanding vehicle. Only the most exceptional vehicles achieve this rating.
4-Star: Very Good vehicle. Very good and close to being the best vehicle in its class.
3-Star: Good vehicle. Decent, but not quite the best. Often affordable, but lacking key features found in vehicles of the same class.
2-Star: Below average vehicle. Not recommended, and lacking attributes a car buyer would come to expect for the price.
1-Star: Poor vehicle. Simply does not deserve to be on the road.
2022 GMC Sierra 3500HD Overview
Choosing Your GMC Sierra 3500HD
You’d need a flowchart to map the different configurations of 3500HD, in a range that is even broader than its 2500HD sibling. Choices include three-seater Regular Cab and six-seater Double/Crew Cab configurations, standard or long beds, gas or diesel engines, 2WD or 4WD, single or dual rear wheel axles, plus five trim levels.
Certain drivetrains and rear axles are only available with particular cab styles or trims, but the range starts at $39,595 including destination for a gas-powered 2WD single rear wheel Regular Cab Long Bed in Pro trim. At the other end of the spectrum, you’ll pay $79,845 for a turbodiesel Crew Cab Long Bed in Denali trim, with all-wheel drive and a dual rear axle.
For the 3500HD, GMC offers a choice of two 6.6-liter engines, starting with a V8 gas unit which produces 401 horsepower and 464 pound-feet of torque. This is supplied to either the rear or all four wheels (all six on dual rear wheel models) through a six-speed automatic transmission.
The 6.6-liter turbodiesel V8 produces 445 hp and 910 lb-ft of torque, allied to a ten-speed transmission with optional Power Take Off.
|6.6 V8 gas||401 hp||464 lb-ft|
|6.6 V8 turbodiesel||445 hp||910 lb-ft|
Passenger and Cargo Capacity
Cargo capacity for the three-seater Regular Cab or six-seater Crew/Double Cab 3500HD models is 69.5 cu ft on Standard Bed models, and 83.5 cu ft on Long Bed.
The level of safety offered by the 3500HD improves as you climb the range, though every model receives six airbags, hitch guidance, LED daytime running lamps, and traction control. SLE models have an integrated trailer brake controller and cruise control, while SLT receives an HD rear vision camera plus hitch view. However, if safety is paramount, you’ll need to either raid the options list or choose range-topping Denali trim. This is the only 3500HD to come with features like emergency braking, front and rear park assist, side blind zone alerts, and lane departure warning.
A color touchscreen infotainment system is standard across the 3500HD range, with Bluetooth and USB ports, but Pro models are otherwise sparsely equipped. SLE trim receives connected services, satellite radio, WiFi capabilities and even steering wheel-mounted audio controls. SLT is the first model with smartphone compatibility, while Denali is a league apart with its navigation, seven-speaker Bose stereo, and superior socketry.
Barring its dash-mounted touchscreen, climbing into a 3500HD Pro is like taking a trip back to the 1990s, with everything either manually operated or completely absent. The only equipment worth noting includes single-zone climate, power locks and windows, plus a 3.5-inch monochrome driver information center.
Putting aside the fact its features should come as standard, the $890 Driver Alert Package I is a must-have on any trim up to Denali. It includes front and rear park assist for this 250-inch truck, plus rear cross-traffic, side blind zone, and lane change alerts. The $615 Safety Confidence Package is equally essential, offering forward collision alert with automatic emergency braking, cruise control, and a 4.2-inch color driver information center with steering-wheel-mounted audio controls.
SLE trim may be basic, but it’s less utilitarian than Pro. Whichever cab, bed, engine, and drivetrain option you choose, there’ll be WiFi connectivity and satellite radio, remote keyless entry, and a leather-wrapped steering wheel. Driver aids include cruise control and a 4.2-inch color driver information center, while the tailgate gains power locking and release plus lift assistance.
The Safety Confidence Pack found on Pro models is renamed Driver Alert Package II, dropping the driver information features in favor of a following-distance indicator, intelligent full beam, and lane departure warning. It costs $595. The $2,330 SLE Convenience Package is also good value, with a dozen features (18 on Crew Cab and Double Cab models) including keyless open and start, heated front seats with 10-way power for the driver, a heated steering wheel, and dual-zone climate.
By the time you reach SLT trim, the 3500HD feels increasingly like a modern vehicle rather than a throwback. An HD rear camera and hitch guidance improve safety alongside an in-vehicle trailering app and an auto-dimming inside mirror. Smartphone compatibility and keyless open with remote starting are welcome touches, while a superior infotainment system and dual-zone climate improve the cabin. The front seats are wrapped in perforated leather with 10-way power, plus memory for the driver.
The $4,670 SLT Premium Package bundles in the Driver Alert Package I alongside a wealth of creature comforts including a Bose sound system and wireless phone projection, navigation and HD surround vision, ventilated front bucket seats, and a rear sliding power window. A more affordable option is the $1,670 SLT Preferred pack, combining a bed view camera and HD surround vision with navigation, the Bose stereo, and wireless device charging.
AT4’s upgrades are mainly focused on mechanical improvements, though this trim does receive ventilated front bucket seats, premium floor liners, and extra connectivity sockets in the cab. The big news involves hill descent control and off-road suspension, all-terrain tires mounted on twin-tube shock absorbers, and underbody skid plates.
AT4 is already reasonably well-equipped, but the $1,475 Technology pack moves it towards SUV levels of luxury with a rearview camera mirror, 15-inch color head-up display, and an eight-inch driver information center. If you really want to treat your truck, the $6,975 AT4 Premium Plus bundle combines the Tech pack with a power sunroof and 20-inch wheels, the two Driver Alert packages, and a wealth of other goodies including navigation, wireless phone charging, a bed view camera, and HD surround vision.
The increase in specification from AT4 to Denali is quite remarkable. This model comes with a comprehensive array of modern safety aids including rear cross-traffic and lane departure warnings, HD surround vision, and parking assistance at both ends of the vehicle. It rides on 20-inch polished aluminum wheels with chrome assist steps and a power sliding rear window, while the cabin is notable for offering navigation and a Bose sound system, plus wireless device charging.
There aren’t many options to add by this point, but the $1,770 Denali Ultimate Package combines a sunroof and rear camera mirror with a 15-inch head-up display. Alternatively, you could drop the sunroof and get the other features for $1,275 in the Technology Package.
SLT trim is at least on nodding terms with modern sensibilities, but you’ll need to raid the options list to bring its safety specs up to scratch. Denali is luxurious but very expensive, while AT4 will suit anyone planning serious off-roading.
