2024 GMC Yukon V (facelift ) 5.3 V8 (355 Hp) Automatic

The GMC Yukon V (facelift 2024) with the 5.3L V8 engine and automatic transmission represents a continuation of GMC’s full-size SUV offerings, updated for the 2024 model year. Positioned as a mainstream offering within the Yukon lineup – slotting below the Denali and AT4 trims – this variant aims to provide a balance of capability, space, and value for families and those needing substantial towing capacity. Production began in late 2023 for the 2024 model year, building upon the foundation of the fifth-generation Yukon (introduced in 2021) with styling and technology refinements. The Yukon, as a whole, competes directly with the Chevrolet Tahoe and Suburban, Ford Expedition, and Jeep Wagoneer.

Technical Specifications

Powertrain & Engine Architecture

The heart of this Yukon V variant is the 5.3-liter L84 V8 engine. This engine is a member of GM’s Small Block family, utilizing an aluminum cylinder block and heads. It employs direct fuel injection, a technology that improves efficiency and power output by injecting fuel directly into the combustion chamber. The engine also features Active Fuel Management (cylinder deactivation), which shuts down four cylinders during light-load driving conditions to further enhance fuel economy. The valvetrain utilizes an overhead valve (OHV) configuration with variable valve timing (VVT) to optimize performance across the engine’s operating range. The 10-speed automatic transmission (likely the 10L80) is a crucial component, offering a wide gear ratio spread for both improved acceleration and relaxed highway cruising. This transmission is electronically controlled and features overdrive for fuel efficiency.

Driving Characteristics

The 5.3L V8 paired with the 10-speed automatic delivers a respectable driving experience, though it’s not focused on outright sportiness. The Yukon V prioritizes smooth, comfortable transportation and towing capability. Acceleration is adequate for everyday driving and merging onto highways, with the 10-speed transmission helping to keep the engine in its optimal power band. Compared to the available 6.2L V8, the 5.3L offers less peak power and torque, resulting in slower acceleration times. However, the 5.3L’s cylinder deactivation system contributes to better fuel economy in certain driving scenarios. The automatic transmission’s gear ratios are tuned for a balance of responsiveness and efficiency, providing relatively quick downshifts when needed. The Yukon’s substantial weight (over 5600 lbs) is noticeable, particularly during braking and cornering, but the suspension does a good job of mitigating body roll.

Equipment & Trim Levels

The Yukon V (facelift 2024) 5.3L Automatic typically comes standard with a comprehensive suite of features. Interior appointments generally include cloth upholstery, though leather is often available as an option. Standard infotainment features include a touchscreen display (typically 8-inch, with larger options available), Apple CarPlay and Android Auto compatibility, and a basic sound system. Safety features such as automatic emergency braking, lane departure warning, and forward collision alert are also commonly included. Optional extras for this trim level often include a sunroof, upgraded sound system, heated and ventilated front seats, power-adjustable pedals, and a rear-seat entertainment system. The facelift for 2024 brought updated interior materials and a revised dashboard layout.

Chassis & Braking

The Yukon V utilizes a body-on-frame construction, providing a robust platform for towing and hauling. 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. Anti-lock brakes (ABS) are standard. The Yukon’s substantial weight necessitates a capable braking system, and the ventilated discs provide adequate stopping power.

Market Reception & Comparison

Critics generally view the Yukon V 5.3L Automatic as a solid, if not particularly exciting, choice in the full-size SUV segment. The 5.3L engine is praised for its reliability and adequate power, while the 10-speed transmission is lauded for its smoothness and efficiency. Fuel economy is typical for a vehicle of this size and weight, averaging around 15-20 mpg combined. Compared to the 6.2L V8 Yukon, the 5.3L offers lower performance but better fuel economy and a lower price point. The 5.3L also represents a more affordable alternative to the diesel-powered Yukon, which prioritizes towing capacity. The Yukon’s spacious interior and ample cargo capacity are consistently highlighted as strengths.

Legacy

The L84 5.3L V8 engine has a long-standing reputation for reliability and durability within the GM product lineup. While not without its potential issues (such as oil consumption in some model years), the engine is generally considered to be a robust and long-lasting powertrain. The 10-speed automatic transmission has also proven to be a reliable unit. In the used car market, Yukon V models with the 5.3L engine are generally well-regarded for their value and practicality. Proper maintenance, including regular oil changes and transmission fluid services, is crucial for ensuring the longevity of this powertrain. As of 2024, these vehicles represent a popular choice for families and those needing a capable and spacious SUV.
