2024 GMC Sierra 1500 Reliability Score & Common Problems

Owners report frequent issues with the 2024 GMC Sierra 1500's engine and engine cooling system, particularly related to engine stalling and loss of power while driving at highway speeds, often without prior warning lights. Complaints commonly mention catastrophic engine failures requiring replacement, with failure mileages ranging from approximately 6,500 to 67,000 miles. A notable pattern involves excessive oil consumption and low oil pressure warnings, sometimes accompanied by metal shavings in the oil filter. Safety implications include sudden loss of motive power, which could pose a risk during high-speed travel. Buyers should be aware of these issues, especially as many vehicles are affected by a recall with parts not yet available for repair.

Owners report recurring issues with the 2024 GMC Sierra 1500's front grille and tailgate structure. Complaints frequently mention the front grille or its components detaching at highway speeds, with instances of it flying off and causing damage to the vehicle's windshield or hood, and posing potential risks to other drivers. This problem is often reported at mileages ranging from 10 to 35,000 miles. Additionally, multiple owners describe the tailgate unexpectedly opening while driving, sometimes resulting in items falling from the truck bed and creating possible road hazards. These issues have been noted without prior warning signals or dashboard alerts, and there are no current recalls addressing these specific problems for the 2024 model.

Owners of the 2024 GMC Sierra 1500 frequently report issues with the brake system, including complete brake failure accompanied by multiple warning lights, and unexpected automatic braking at highway speeds. Complaints note irregular brake wear, with one owner needing brake replacements three times within 30,000 miles, and another experiencing a crash when the brake pedal went to the floor without stopping the vehicle. Additionally, there are reports of the trailer brake controller intermittently disconnecting. Safety implications are significant, with one crash reported, and issues typically arise around 13,000 to 46,000 miles. This information may be critical for potential buyers considering the vehicle's brake system reliability.

Owners report recurring power steering issues with the 2024 GMC Sierra 1500, often involving a complete loss of steering assist. Symptoms described include the steering wheel becoming inoperable or difficult to maneuver, accompanied by multiple dashboard warning lights such as "Service Power Steering" and "Steering Assist Reduced." These issues typically occur at mileages ranging from 5,754 to 28,140 miles and have been reported to persist even after attempted repairs. Safety implications include difficulty steering at lower speeds and potential loss of control, particularly concerning when driving at highway speeds. Buyers should be aware of these patterns, as they suggest potential safety risks and ongoing repair challenges.

Owners of the 2024 GMC Sierra 1500 report issues with the forward collision avoidance systems, particularly involving the SuperCruise feature and automatic emergency braking. Complaints frequently mention the SuperCruise system crossing double yellow lines and making erratic lane changes, especially following a software update in May 2025. Another common issue involves unexpected deceleration on highways, with one owner describing the vehicle suddenly slowing down and not responding to acceleration inputs. At least one incident involved a crash where the automatic emergency braking failed to activate, resulting in a rear-end collision at low speed. These issues are reported at various mileage points, including as early as 500 miles, and pose potential safety risks such as loss of control and collision.

Owners of the 2024 GMC Sierra 1500 report issues related to the suspension, including improperly attached differential and rear axle supports, which can lead to abnormal metal-on-metal sounds and warning messages. One report describes a severe incident where a front tire detached, resulting in vehicle damage and an injury, highlighting potential safety concerns. Additionally, some owners experience problems with shocks, such as leaking fluid shortly after purchase, with one case occurring at only 108 miles. These complaints suggest that suspension issues can arise at both low and high mileages, and may include safety risks like loss of control or vehicle damage.

Owners of the 2024 GMC Sierra 1500 report issues with the vehicle's visibility systems, particularly involving the sunroof and backup camera. One owner describes a sunroof explosion while driving, which resulted in glass falling inside the cabin and causing an injury. Additionally, multiple complaints highlight inadequate illumination from the rear view camera, rendering it ineffective for nighttime use. These reports suggest that the backup camera displays primarily dark and red spots, making it difficult to see obstacles behind the vehicle in low-light conditions. The incidents occur without specific mileage data, but the safety implications include potential injury from the sunroof failure and compromised rear visibility at night.
