The GMC Yukon XL V, specifically the 2024 facelift model equipped with the 5.3-liter V8 engine and automatic transmission, represents a significant offering in the full-size SUV segment. Introduced as part of the fifth-generation Yukon XL (introduced in 2021), the 2024 refresh brought updated styling and technology. This particular configuration positions itself as a mainstream offering within the Yukon XL lineup, balancing capability, space, and price point. It caters to buyers needing substantial passenger and cargo capacity, along with the towing ability expected of a full-size SUV, without the premium price tag of the Denali or AT4 trims.

Powertrain & Engine Architecture
At the heart of the 2024 Yukon XL V is the GM L84 5.3-liter V8 engine. This engine is a member of GM’s Small Block family, known for its durability and relatively simple design. The L84 utilizes direct fuel injection, a key technology for improving both power and fuel efficiency. The engine also incorporates Active Fuel Management (cylinder deactivation), which shuts down four cylinders during light-load driving conditions to further enhance fuel economy. The valvetrain employs an overhead valve (OHV) configuration with variable valve timing (VVT) to optimize performance across the engine’s operating range. The engine is longitudinally mounted in the chassis, driving the rear wheels. Paired with the L84 is a 10-speed automatic transmission (likely the 10L80), providing a wide gear ratio spread for improved acceleration and highway cruising. This transmission is electronically controlled and features overdrive for optimal fuel efficiency.
Driving Characteristics
The 5.3L V8 and 10-speed automatic combination in the Yukon XL V delivers a comfortable and capable driving experience. While not as quick as the 6.2L V8 option, the 355 horsepower and 382 lb-ft of torque provide ample power for everyday driving and towing. The 10-speed transmission is well-tuned, offering smooth and responsive shifts. The wide gear ratios help keep the engine in its optimal power band, resulting in good acceleration from a standstill and confident passing power. Compared to a manual transmission (not offered on the Yukon XL), the automatic provides ease of use and convenience, particularly in city traffic. The Yukon XL V doesn’t feel particularly sporty, prioritizing comfort and refinement over aggressive handling. The large size and weight of the vehicle are noticeable, but the suspension does a good job of absorbing bumps and providing a stable ride.
Equipment & Trim Levels
The Yukon XL V, as a mid-range trim, typically comes standard with a respectable array of features. These generally include tri-zone automatic climate control, an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a rear vision camera, and a suite of safety features like automatic emergency braking and lane keep assist. Interior upholstery is typically cloth, with options for leather upgrades. Standard dashboard configuration includes analog gauges with a digital information display. Popular optional extras for this trim often include a power liftgate, heated front seats, a premium audio system, and various driver-assistance technologies like adaptive cruise control and blind-spot monitoring.
Chassis & Braking
The Yukon XL V utilizes a body-on-frame construction, providing a robust and durable platform. The front suspension consists of an independent coil spring setup with a transverse stabilizer bar. The rear suspension employs an independent multi-link spring suspension, also with a stabilizer bar. Air suspension is available as an option, providing adjustable ride height and improved ride comfort. Braking duties are handled by ventilated discs at all four corners, with the front discs measuring 343×30.4 mm and the rear discs measuring 345×20 mm. The braking system is assisted by ABS (Anti-lock Braking System) and electronic brake-force distribution. Steering is rack-and-pinion with electric power assist.
Market Reception & Comparison
The 2024 GMC Yukon XL V with the 5.3L V8 and automatic transmission was generally well-received by automotive critics. It was praised for its spacious interior, comfortable ride, and capable towing capacity. Fuel economy, however, was a common criticism, as expected for a vehicle of this size and weight. Compared to the 6.2L V8 Yukon XL, the 5.3L offered a more affordable entry point, but with a noticeable decrease in performance. Compared to the diesel-powered Yukon XL (if available), the 5.3L offered a simpler and potentially more reliable powertrain, but with lower fuel economy and torque. The Yukon XL V competed directly with other full-size SUVs like the Chevrolet Suburban, Ford Expedition, and Nissan Armada.
Legacy
The GM L84 5.3L V8 engine has proven to be a reliable and durable powertrain over the years. While long-term reliability data for the 2024 facelift model is still emerging, the engine’s established track record suggests it should provide years of dependable service with proper maintenance. In the used car market, the Yukon XL V with this powertrain represents a good value proposition for buyers seeking a spacious and capable SUV. The 10-speed automatic transmission is also considered a strong point, contributing to both performance and fuel efficiency. As with any used vehicle, a thorough inspection and maintenance history review are recommended before purchase.
