The GMC Canyon II, specifically the facelifted version introduced for the 2021 model year, represents General Motors’ mid-size pickup truck offering. This iteration of the Canyon, built on the GMT-315 platform, aimed to provide a blend of capability, comfort, and technology in a package smaller than the full-size Sierra. The 2021-2022 Crew Cab Long Box configuration with the 3.6-liter V6 engine producing 308 horsepower and paired with an 8-speed automatic transmission, represented a popular and well-rounded trim level within the Canyon lineup, targeting buyers seeking a balance between work and everyday usability. This variant occupied a mid-range position, offering more power and refinement than the base four-cylinder models, but falling short of the more expensive and off-road focused AT4 trim.

Powertrain & Engine Architecture
At the heart of this Canyon variant lies the 3.6-liter LFX V6 engine. This engine is a naturally aspirated, 60-degree V6 featuring direct fuel injection and a double overhead camshaft (DOHC) valvetrain with continuously variable valve timing (CVVT). The LFX engine is known for its relatively smooth operation and respectable power output. The direct injection system contributes to improved fuel efficiency and reduced emissions. The 8-speed Hydra-Matic automatic transmission, a GM staple, provides smooth and efficient gear changes. This transmission is designed to optimize fuel economy while still providing adequate performance for towing and hauling. The transmission’s gear ratios are tuned to balance acceleration with highway cruising efficiency.
Driving Characteristics
The 308-horsepower V6 and 8-speed automatic combination delivers a competent driving experience. While not a performance-oriented setup, it provides sufficient power for everyday driving and towing. Acceleration from a standstill is adequate, and the transmission generally shifts smoothly. Compared to the base 2.5-liter four-cylinder engine, the V6 offers a noticeable improvement in both acceleration and towing capacity. However, it doesn’t possess the low-end torque of the available Duramax diesel engine. The automatic transmission, while generally smooth, can sometimes feel hesitant during quick downshifts. The 4WD system provides enhanced traction in inclement weather or off-road conditions, but this Canyon isn’t designed for serious off-roading like the AT4 trim.
Equipment & Trim Levels
The 2021-2022 Canyon Crew Cab Long Box 3.6L V6 4WD typically came standard with features such as an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a rearview camera, and keyless entry. Higher trim levels added features like leather upholstery, heated front seats, a premium audio system, and advanced safety technologies like forward collision alert and lane departure warning. Optional extras included a trailering package, off-road suspension, and various appearance packages. Interior materials were generally durable and functional, reflecting the truck’s work-oriented nature.
Chassis & Braking
The Canyon II utilizes a traditional body-on-frame construction, providing a robust and durable platform. The front suspension consists of independent coil springs, while the rear suspension employs a rigid axle with leaf springs. This setup is designed to handle heavy loads and provide a comfortable ride. Braking duties are handled by disc brakes on all four wheels, with ABS included as standard. The braking system is adequate for the truck’s weight and performance, but it doesn’t offer the same stopping power as some competitors. The standard tire size is typically 255/65R17 or 265/65R17, depending on the trim level.
Market Reception & Comparison
The 2021-2022 GMC Canyon with the 3.6L V6 and automatic transmission received generally positive reviews. Critics praised its comfortable ride, user-friendly infotainment system, and capable powertrain. However, some reviewers noted that the interior felt dated compared to newer competitors. Fuel economy was considered average for the segment. Compared to the four-cylinder Canyon, the V6 offered a significant performance upgrade, but at the cost of slightly lower fuel efficiency. The diesel-powered Canyon offered superior towing capacity and fuel economy, but came with a higher price tag.
Legacy
The LFX 3.6L V6 engine and 8-speed automatic transmission pairing proved to be a reliable combination in the Canyon. While not without its minor quirks, the powertrain is generally considered durable and relatively easy to maintain. In the used car market, these Canyon models represent a good value for buyers seeking a capable and comfortable mid-size pickup truck. Regular maintenance, including oil changes and transmission fluid services, is crucial for ensuring the long-term reliability of this powertrain. As of 2024, well-maintained examples of this Canyon variant continue to be a popular choice among truck buyers.
