The 2024 GMC Sierra HD has arrived, bringing with it a host of upgrades and innovations that are set to redefine the heavy-duty truck segment. This latest iteration of GMC’s popular pickup line introduces cutting-edge technology, enhanced performance, and luxurious features that cater to both work and leisure.
Powertrain Enhancements
At the heart of the 2024 Sierra HD lies an improved 6.6-liter Duramax Turbo-Diesel V8 engine. This powerhouse now delivers an impressive 470 horsepower and a staggering 975 lb-ft of torque, representing a significant increase in low-end torque compared to its predecessor. The engine is paired with a 10-speed Allison transmission, providing smooth and efficient power delivery across all driving conditions.
Improved Towing Capacity: The 2024 model boasts an increased maximum towing capacity of up to 36,000 pounds when properly equipped. This enhancement is complemented by an array of new trailering technologies designed to make hauling safer and more manageable.
Technological Advancements
GMC has significantly upgraded the Sierra HD’s tech offerings for 2024. The truck now features a 13.4-inch touchscreen infotainment system powered by Android Automotive. This system provides access to Google services, including Google Maps and Google Assistant, even without a connected smartphone.
Enhanced Safety Features: The Sierra HD Pro Safety package now comes standard across all trims. It includes Forward Collision Alert, Following Distance Indicator, Front Pedestrian Braking, IntelliBeam, Lane Departure Warning, and Automatic Emergency Braking.
Exterior and Interior Upgrades
The 2024 Sierra HD receives a facelift with a redesigned front fascia, new LED projector headlamps with animated lighting sequences, and updated wheel designs. The interior has also been revamped, with premium materials and finishes, especially in the higher trims like the Denali and the new Denali Ultimate.
First-Ever Denali Ultimate: This new top-tier trim level offers the pinnacle of luxury in the Sierra HD lineup, featuring exclusive exterior styling elements and a lavishly appointed interior.
Off-Road Capability: AT4X and AT4X AEV Edition
GMC is expanding its off-road offerings with the introduction of the AT4X trim later in the model year. The AT4X AEV Edition takes things a step further, featuring a 1.5-inch suspension lift, 35-inch Goodyear Territory MT tires, and Multimatic DSSV dampers for superior off-road performance.
Addressing Previous Issues
GMC has taken steps to address some of the concerns raised by owners of previous models. The infotainment system, which had been a point of contention in earlier versions, has been completely overhauled with the new Android Automotive-based system. This change aims to provide a more responsive and user-friendly interface.
Transmission Refinement: Some owners of previous models reported issues with transmission tuning. GMC claims to have refined the transmission software for smoother operation, particularly in low-speed situations and when towing.
Potential Concerns
While the 2024 Sierra HD brings numerous improvements, early adopters should be aware of potential teething issues. Some owners of early production models have reported occasional glitches with the new infotainment system, particularly related to GPS connectivity. GMC has acknowledged these issues and is working on software updates to address them.
Start-Up Issues: A small number of 2024 Sierra HDs equipped with the 3.0L LZ0 engine have experienced start-up problems related to a software anomaly. GMC has issued a preliminary Technical Service Bulletin (TSB) to address this issue, which may require ECM replacement in some cases.
Conclusion
The 2024 GMC Sierra HD represents a significant step forward in the heavy-duty truck segment. With its blend of power, technology, and luxury, it aims to satisfy the needs of both work-oriented users and those seeking a premium truck experience. While some early production issues have been reported, GMC’s proactive approach to addressing these concerns should provide reassurance to potential buyers.
As with any new vehicle launch, it’s advisable for interested buyers to stay informed about early user experiences and keep an eye on any developing issues. However, the comprehensive upgrades and new features make the 2024 Sierra HD a compelling option in the competitive heavy-duty truck market.
